Celestia Aerospace, Lanzarsatélites desde un avión de caza








Lanzar satélites desde un avión de caza
El espacio parecía coto privado de las grandes agencias espaciales y algunos ejércitos. Pero cada vez hay más empresas privadas con ganas de hacerse un hueco entre las grandes empresas públicas  y poner su granito de arena en órbita, o en Marte.
Lanzar satélites desde un avión no es idea nueva: Ahí estaba el Pegasus lanzado desde un L1011, ni tampoco es la 1ª vez que se quiere hacer desde un caza. Esto no significa que no sea buena idea o no sea original.  En la historia hay muchos ejemplos de distintos inventos que no funcionaron  porque no llegaron en el momento adecuado, o la tecnología no estaba madura, como el motor a reacción que lleva con nosotros desde 1910 o las aeronaves no tripuladas, que llevan con nosotros desde que Torres Quevedo quiso montar su Telekino en un dirigible a comienzos del siglo XX. Para que una idea triunfe se necesita que sea posible llevarlo a cabo más allá del demostrador tecnológico y que sea económico. Y por supuesto, demanda.
-        ¿Por qué podría funcionar vuestro proyecto ahora, y no los de antes?
La idea no es nueva, pero los anteriores intentos han pecado principalmente de dos importantes defectos: iban a un rango de masas demasiado elevado, requiriendo de importantes modificaciones en el avión e incluso el apoyo de otros aviones; y aparecieron cuando la utilidad de los nanosatélites era muy limitada.
-        ¿Los nanosatélites no son muy pequeños para ser útiles? La miniaturización actual es la razón principal del boom de los nanosatélites: permite un gran número de aplicaciones, observación de la Tierra, comunicaciones seguras de banda estrecha, certificación de componentes que han de viajar al espacio en otros satélites de mayor tamaño…
-        ¿Las constelaciones de nanosatélites no empeoran el problema de la basura espacial?
La ventaja es que van a órbitas llamadas LEO (Low-Earth Orbit) en las cuales la atmósfera todavía está presente y existe una mínima resistencia que hace que los satélites se frenen y reentren a la atmósfera a los 2 años aproximadamente, desintegrándose totalmente.
-        ¿Por qué un ex caza?
El MiG-29 es perfecto para este cometido: es un interceptor puro, diseñado para subir hasta los 20 km de altura en un tiempo récord. Además, se trata de un modelo que lleva operando desde los años 80, por lo que las primeras unidades ya han comenzado a pasar al sector privado lo cual los hace lo asequibles como para hacer que la operación sea rentable.
-        ¿Otros usos para el MiG?
Como mercado secundario, utilizarlo para dar vuelos VIP supersónicos hasta los 20 km de altura, donde comienza a apreciarse la curvatura de la Tierra o contemplar gran parte del Mediterráneo de un solo vistazo.
-        ¿Cualquier aeropuerto serviría?
Cualquiera con una pista de 2 km o más es una base de operaciones viable, por lo que podemos desplazar el avión allí donde el cliente indique.
-        ¿Qué ventajas tiene utilizar este sistema?
Existe un término para definir el punto fuerte de nuestro sistema: Rapid Response. A diferencia de otros sistemas de lanzamiento, permite a un cliente que disponga de uno o más nanosatélites con todos los permisos en regla lanzarlos a órbita en un tiempo récord, ya que el avión se encontrará en estado de vuelo constantemente y dispondremos de un stock de lanzadores (un cohete de 7 m de largo y 1000kg de masa al que hemos bautizado Space Arrow) listos para ser acoplados al avión.

En la actualidad Celestia dispone de todos los permisos para comenzar la campaña de vuelos de prueba en un tiempo no superior a 6 meses, y busca inversores para cerrar la Serie A que permitirá la adquisición del MiG-29UB, lanzadores, y todos los costes de operación hasta el inicio de lanzamientos comerciales.

Planetary Exploration Rover Avoids Sand Traps with “Rear Rotator Pedaling”





(A) NASA’s RP15 prototype. (B) The Mini Rover resting on a bed of loosely packed poppy seeds on an incline of θbed ≈ 20∘. (C) Four top-view rendered snapshots of the Mini Rover executing a quadrupedal gait: an RS gait with no modulation. In the RS gait, all wheels except the one colored in red sweep toward the rear of the rover for 2.7 s. The sweep direction for each wheel in each snapshot is shown with the black arrows. Once the sweep is complete, the wheel begins the reset phase, where the wheel is colored in red. The Mini Rover lifts the resetting wheel with its four-bar linkage and rotates it 90° toward the front of the rover in 0.9 s. The reset direction for each wheel is shown in red arrows.

The rolling hills of Mars or the moon are a long way from the nearest tow truck. That’s why the next generation of exploration rovers will need to be good at climbing hills covered with loose material and avoiding entrapment on soft granular surfaces.

Built with wheeled appendages that can be lifted and wheels able to wiggle, a new robot known as the “Mini Rover” has developed and tested complex locomotion techniques robust enough to help it climb hills covered with such granular material – and avoid the risk of getting ignominiously stuck on some remote planet or moon.

Using a complex move the researchers dubbed “rear rotator pedaling,” the robot can climb a slope by using its unique design to combine paddling, walking, and wheel spinning motions. The rover’s behaviors were modeled using a branch of physics known as terradynamics.

“When loose materials flow, that can create problems for robots moving across it,” said Dan Goldman, the Dunn Family Professor in the School of Physics at the Georgia Institute of Technology. “This rover has enough degrees of freedom that it can get out of jams pretty effectively. By avalanching materials from the front wheels, it creates a localized fluid hill for the back wheels that is not as steep as the real slope. The rover is always self-generating and self-organizing a good hill for itself.”

The research was reported on May 13 as the cover article in the journal Science Robotics. The work was supported by the NASA National Robotics Initiative and the Army Research Office.

A robot built by NASA’s Johnson Space Center pioneered the ability to spin its wheels, sweep the surface with those wheels and lift each of its wheeled appendages where necessary, creating a broad range of potential motions. Using in-house 3D printers, the Georgia Tech researchers collaborated with the Johnson Space Center to re-create those capabilities in a scaled-down vehicle with four wheeled appendages driven by 12 different motors.

“The rover was developed with a modular mechatronic architecture, commercially available components, and a minimal number of parts,” said Siddharth Shrivastava, an undergraduate student in Georgia Tech’s George W. Woodruff School of Mechanical Engineering. “This enabled our team to use our robot as a robust laboratory tool and focus our efforts on exploring creative and interesting experiments without worrying about damaging the rover, service downtime, or hitting performance limitations.”

The rover’s broad range of movements gave the research team an opportunity to test many variations that were studied using granular drag force measurements and modified Resistive Force Theory. Shrivastava and School of Physics Ph.D. candidate Andras Karsai began with the gaits explored by the NASA RP15 robot, and were able to experiment with locomotion schemes that could not have been tested on a full-size rover.

The researchers also tested their experimental gaits on slopes designed to simulate planetary and lunar hills using a fluidized bed system known as SCATTER (Systematic Creation of Arbitrary Terrain and Testing of Exploratory Robots) that could be tilted to evaluate the role of controlling the granular substrate. Karsai and Shrivastava collaborated with Yasemin Ozkan-Aydin, a postdoctoral research fellow in Goldman’s lab, to study the rover motion in the SCATTER test facility.

“By creating a small robot with capabilities similar to the RP15 rover, we could test the principles of locomoting with various gaits in a controlled laboratory environment,” Karsai said. “In our tests, we primarily varied the gait, the locomotion medium, and the slope the robot had to climb. We quickly iterated over many gait strategies and terrain conditions to examine the phenomena that emerged.”

In the paper, the authors describe a gait that allowed the rover to climb a steep slope with the front wheels stirring up the granular material – poppy seeds for the lab testing – and pushing them back toward the rear wheels. The rear wheels wiggled from side-to-side, lifting and spinning to create a motion that resembles paddling in water. The material pushed to the back wheels effectively changed the slope the rear wheels had to climb, allowing the rover to make steady progress up a hill that might have stopped a simple wheeled robot.

The experiments provided a variation on earlier robophysics work in Goldman’s group that involved moving with legs or flippers, which had emphasized disturbing the granular surfaces as little as possible to avoid getting the robot stuck.

“In our previous studies of pure legged robots, modeled on animals, we had kind of figured out that the secret was to not make a mess,” said Goldman. “If you end up making too much of a mess with most robots, you end up just paddling and digging into the granular material. If you want fast locomotion, we found that you should try to keep the material as solid as possible by tweaking the parameters of motion.”

But simple motions had proved problematic for Mars rovers, which got stuck in granular materials. Goldman says the gait discovered by Shrivastava, Karsai and Ozkan-Aydin might be able to help future rovers avoid that fate.

“This combination of lifting and wheeling and paddling, if used properly, provides the ability to maintain some forward progress even if it is slow,” Goldman said. “Through our laboratory experiments, we have shown principles that could lead to improved robustness in planetary exploration – and even in challenging surfaces on our own planet.”

The researchers hope next to scale up the unusual gaits to larger robots, and to explore the idea of studying robots and their localized environments together. “We’d like to think about the locomotor and its environment as a single entity,” Goldman said. “There are certainly some interesting granular and soft matter physics issues to explore.”

Though the Mini Rover was designed to study lunar and planetary exploration, the lessons learned could also be applicable to terrestrial locomotion – an area of interest to the Army Research Laboratory, one of the project’s sponsors.

"This basic research is revealing exciting new approaches for locomotion in complex terrain," said Dr. Samuel Stanton, program manager, Army Research Office, an element of the U.S. Army Combat Capabilities Development Command's Army Research Laboratory. "This could lead to platforms capable of intelligently transitioning between wheeled and legged modes of movement to maintain high operational tempo."

Beyond those already mentioned, the researchers worked with Robert Ambrose and William Bluethmann at NASA, and traveled to NASA JSC to study the full-size NASA RP15 rover.

This work was supported by the Army Research Office (W911NF-18-1-0120) and the NASA National Robotics Initiative (NNX15AR21G).

Material remodeling and unconventional gaits facilitate locomotion of a robophysical rover over granular terrain

Abstract
Autonomous robots and vehicles must occasionally recover from locomotion failure in loosely consolidated granular terrain. Recent mobility challenges led NASA Johnson Space Center to develop a prototype robotic lunar rover Resource Prospector 15 (RP15) capable of wheeled, legged, and crawling behavior. To systematically understand the terradynamic performance of such a device, we developed a scaled-down rover robot and studied its locomotion on slopes of dry and wet granular media. Addition of a cyclic-legged gait to the robot’s wheel spinning action changes the robot dynamics from that of a wheeled vehicle to a locomotor paddling through frictional fluid. Granular drag force measurements and modified resistive force theory facilitate modeling of such dynamics. A peculiar gait strategy that agitates and cyclically reflows grains under the robot allows it to “swim” up loosely consolidated hills. Whereas substrate disturbance typically hinders locomotion in granular media, the multimode design of RP15 and a diversity of possible gaits facilitate formation of self-organized localized frictional fluids that enable effective robust transport.

Rolls-Royce launches first immersive virtual reality training for business aviation customers







press release




Even during the COVID-19 pandemic, Rolls-Royce continues to ensure world-class support for our global customer base. As part of our IntelligentEngine vision we are further expanding the use of immersive Virtual Reality technology for customer training.

The latest addition to the remote training programme is an instructor-led distance learning course, providing a comprehensive overview of the construction, design and operation of the Rolls-Royce BR725 engine that powers Gulfstream’s current flagship G650 business aircraft family. After completion of this comprehensive two-day training course, participants will be able to service the engine and undertake non-routine maintenance.

Andy Robinson, SVP Customers and Services - Business Aviation, Rolls-Royce, said: “Rolls-Royce has been the leading engine supplier for business aircraft for more than two decades thanks to our continued commitment to the highest levels of service support. We are tremendously proud to have been voted number one in the latest Engine Product Support Services Survey of Aviation International News (AIN) by our operators.


Digitalisation plays a vital role in in bringing our IntelligentEngine vision to life; we use it to design, test and maintain our engines. This new immersive live Virtual Training tool is nothing short of a game-changer - it makes us the leader in technical training and allows customers to participate in the new training, wherever they are in the world. They just need an internet connection, and the required VR equipment, which will be shipped directly to their door,” Andy added.

Lee Bradshaw, Director of Technical Operations, Cox Aviation, said: “The new Virtual Reality maintenance course is a great example of the innovative thinking that is needed to meet the challenges of our ever-changing world. This programme allows each student to immerse themselves in an augmented environment full of realistic images, interactive functions and auditory feedback to delve deeper into the engine like never before. The course complements the industry-leading service already provided by Rolls-Royce and is another reminder of why this company is pioneering the way in creative solutions for the future.”

While not intended to completely replace practical training, Rolls-Royce see the value Virtual Reality adds for customers, such as higher flexibility and the elimination of the need to ship a full size training engine. The user finds themself as part of two realistic scenarios – the engine installed on the aircraft in a virtual hangar and the BR725 engine alone, just like it would be in our in-person training courses. The immersive environment allows them not only to watch the process steps to get familiar with the respective task, but to interact with the engine and the tools, and actually accomplish the task under the constant supervision of the instructor.

The Boeing [NYSE: BA]-built X-37B autonomous spaceplane today launched on top of a uniquely configured United Launch Alliance Atlas V rocket.

Boeing is the prime contractor for the X-37B spaceplane and facilitates the integration of all experiments into the vehicle ensuring they receive the correct power, thermal and data services required. Boeing also works to identify future reusable platform experiment opportunities on each mission.

The X-37B’s sixth mission is the first to use a service module with additional payload capability to support a variety of experiments for multiple government partners. The mission will deploy FalconSAT-8, a small satellite developed by the U.S. Air Force Academy and sponsored by the Air Force Research Laboratory, to conduct experiments on orbit. Further, two NASA experiments will study the impact of radiation and other space effects on certain materials and seeds used to grow food. Another experiment by the Naval Research Laboratory will transform solar power into radio frequency microwave energy which could then be transmitted to the ground. In addition, the mission will test reusable space vehicle technologies.

The X-37B first launched in April 2010. Originally designed for missions of 270 days duration, the X-37B has set endurance records during each of its five previous flights. Most recently, X-37B spent 780 days on orbit before returning to Earth in October 2019.

“The X-37B has shifted the paradigm and redefined efficiency in space development, said Jim Chilton, Boeing Space and Launch senior vice president. “The rapid technology advancements enabled by the program will benefit the entire space community and influence the next generation of spacecraft design.”

The X-37B program is a partnership between the Department of the Air Force Rapid Capabilities Office and the United States Space Force. Boeing program management, engineering, test and mission support functions for the Orbital Test Vehicle (OTV) program are conducted at Boeing sites in Southern California and Florida.

Future Combat Air System: Airbus and Fraunhofer FKIE create expert panel on the responsible use of new technologies



press release


In the frame of the Future Combat Air System (FCAS),
Airbus (stock exchange symbol: AIR) and Bonn, Germany-based Fraunhofer Institute for Communication, Information Processing and Ergonomics FKIE have created an independent panel of experts on the responsible use of new technologies to define and propose ethical as well as international legal “guard rails” for Europe’s largest defence project.

The expert panel, which was first initiated in Germany in 2019, currently includes stakeholders such as the German Ministry of Defence, German Ministry of Foreign Affairs, foundations, universities as well as think tanks.

“In many ways, FCAS represents a giant leap forward. Not only is it Europe’s largest defence programme in the coming decades, which will foster collaboration across our partner nations. With FCAS we`ll be significantly stepping up our game in terms of new technologies which will form part of this sixth-generation ‘System of Systems’”, said Dirk Hoke, Chief Executive Officer of Airbus Defence and Space. “This opens up new opportunities in terms of security policy and helps to strengthen Europe's role in the world. But there are also ethical and legal challenges which we have to address.”

The FCAS programme reflects a complex and extensive networked “System of Systems”, of which a next generation manned fighter will represent one key element. Such manned platforms will team with unmanned ones, called "remote carriers", which will be providing additional capabilities to complete the missions at stake. Scalable and interoperable system architectures will allow upgraded existing platforms to be integrated into FCAS. Leveraging the collaborative capabilities of manned and unmanned platforms will require an "Air Combat Cloud" fusing in real time massive amounts of data augmented by warfare analytics and articifical intelligence. Furthermore, it is expected that the technologies developed in the frame of this project will also have significant beneficial spill-over effects for future civil applications.

Professor Reimund Neugebauer, President of Fraunhofer-Gesellschaft e. V., added: “FCAS is the largest and most technologically ambitious European defense program ever. One essential question we’re trying to tackle with this panel is how we can ensure that, on the one hand, such a system meets the necessary mission requirements of the 21st century on a global scale, while, on the other hand, ensuring full human control of such a system at all times and under all circumstances. For the first time in the history of the Federal Republic of Germany, a major defense policy project is accompanied from the start by the intellectual struggle for the technical implementation of basic ethical and legal principles – “ethical and legal compliance by design".”

In order to create the greatest possible transparency over the proceedings of the expert panel, a website was established: www.fcas-forum.eu. All panel members make their contribution free of charge and are solely committed to their conscience.

An interview by Dirk Hoke and Professor Reimund Neugebauer further outlining the panel’s purpose and partnership can be read here: http://www.fcas-forum.eu/en/interview.

In order to reflect the European nature of the FCAS programme, it is foreseen in due course to broaden the panel to further participating nations.

Aciturri completa la fabricación y entrega de una nueva versión de la sección S19 del A350

https://www.aciturri.com/es/press-media/noticias/aciturri-completa-fabricacion-entrega-nueva-version-seccions19-a350 

Nota de prensa


Dentro del paquete de trabajo de rediseño y fabricación de la estructura interna de la Sección 19 (S19) del A350, Aciturri ha completado la entrega de todos los componentes correspondientes a la nueva configuración del avión, conocida como Step 7, que incluye, entre otras significantes mejoras, una ampliación de la cabina de pasajeros.

Para lograrlo, se han fabricado numerosas piezas y montajes respondiendo al nuevo diseño del fuselaje posterior de la aeronave, resultado de mover el mamparo de presión (Rear Pressure Bulkhead) hacia la cola del avión. Esto facilitaba la posibilidad de ampliar la capacidad de pasajeros o aumentar la distancia de separación entre ellos y, por ende, incrementaba el volumen de piezas inicialmente previstas.

Entre las piezas fabricadas se incluyen, principalmente, nuevas cuadernas y refuerzos, así como un gran cambio en todos los soportes de sistemas. Esta nueva configuración implica, inicialmente, una serie de modificaciones en las piezas ya fabricadas, que se entregarán en paralelo a las versiones anteriores. La cadencia de entregas de esta nueva configuración irá aumentando durante los próximos años hasta alcanzar un "full rate".  

Desde el punto de vista tecnológico, esta nueva configuración incluye piezas complejas de RTM, forjas de aluminio, mecanizados de titanio y piezas de ATL y termoconformado.

Éste ha sido un proyecto de gran envergadura para la compañía, donde se ha involucrado la totalidad de la cadena de valor de Aciturri y donde han participado los equipos de las plantas de Aerostructures en Ayuelas (Burgos), Boecillo (Valladolid), Tres Cantos (Madrid) y Sevilla. De igual forma, ha participado una extensa lista de colaboradores de nuestra cadena de suministro. A todos agradecemos el esfuerzo y compromiso con el proyecto.

Está previsto que Airbus finalice el montaje del primer A350 con esta nueva configuración en los próximos meses.

Impacts of COVID-19 pandemic on Aero Vodochody



press release





Like any other company on international market, AERO Vodochody AEROSPACE is confronted with unforeseeable impacts of the COVID-19 pandemic. The management of Aero decided to keep the company running and operational in all activities: MRO, aerostructures, and the L-39NG project.

Aero fully continues its L-39NG activities with target to achieve certification in September 2020. The aerostructures programs are naturally more impacted by the pandemic of the coronavirus due to production shortage of some customers or due to lack of parts and material deliveries from suppliers, which has stronger impact to commercial programs due to their higher production cadences. The running MRO business as defence business, proven by previous crises, is subject to different cycles and patterns than civil aviation and is much more resilient. Furthermore AERO has a very high backlog on MRO business. However, like for almost all aviation companies it will be impossible for Aero to meet the targets originally set for 2020 prior the crisis.

Since beginning of COVID-19 governmental measures, Aero has implemented a comprehensive package of hygienic, safety, technical and personnel measures to minimize the risks of a pandemic situation and to ensure conditions for business continuity.

DARPA's Blackjac aims to demonstrate advanced technology for satellite constellation autonomy and space mesh networks



press release




In partnership with the U.S. Space Force and Space Development Agency, DARPA’s Blackjack program is targeting flights to low-Earth orbit (LEO) later this year and 2021. Using a series of small risk reduction satellites, the program aims to demonstrate advanced technology for satellite constellation autonomy and space mesh networks. Blackjack seeks to develop and validate critical elements of global high-speed autonomous networks in LEO, proving a capability that could provide the Department of Defense with highly connected, resilient, and persistent overhead coverage.

The upcoming demonstration flights are all planned as rideshares, catching a ride to LEO on a launch with other missions. The first demonstration, Mandrake 1, is a cubesat that will carry supercomputer processing chips. Mandrake 2 is a pair of small satellites that will carry optical inter-satellite links for broadband data. These could form the basis of future optically meshed computer networks in LEO.

The program also is targeting a risk reduction payload called Wildcard, a software-defined radio that will experiment with links from LEO to tactical radios. A data fusion experiment with the ability to host advanced third party algorithms, known as massless payloads, is intended for an upcoming Loft Orbital mission.

“It's important that we get the design right,” says Paul “Rusty” Thomas, the program manager for Blackjack. “We focused first on buses and payloads, then the autonomous mission management system, which we call Pit Boss. We anticipate we'll begin integrating the first two military payloads next summer with launch via rideshare in late 2021, followed by the remainder of the Blackjack demonstration sub-constellation in 2022.”

Blackjack aims to demonstrate sensors that are low in size, weight, and power, and that can be mass produced to fit on many different buses from many different providers, for less than $2 million per payload.

The agency is evaluating buses from Airbus, Blue Canyon Technologies, and Telesat, all of which have progressed through preliminary design review. The final selection of buses will happen in 2020. The program recently completed preliminary design review for Pit Boss, selecting SEAKR as the primary performer for the on-orbit autonomy system. The agency also awarded a contract to Lockheed Martin as the satellite integrator.

Several sensor payloads are under consideration for the Blackjack demonstration sub-constellation, including overhead persistent infrared (OPIR) from Collins Aerospace and Raytheon; radio frequency systems from Northrop Grumman Mission Systems, Trident, and Systems & Technology Research; position, navigation, and timing from Northrop Grumman; optical inter-satellite links from SA Photonics; and electro-optical/infrared from L3Harris. The program also recently completed a Small Business Innovation Research contract with Augustus Aerospace to work on an Army Space and Missile Defense Command-related payload.

Over the next few months, the program will run simulations to test payloads in virtual constellations of all types of missions. The goal is to show interoperability between the commoditized buses and the various payloads being considered.

“We need to show the constellations can move the right amount of data and support the data fusion and command and control we want from Pit Boss,” Thomas said. “From there, we will start building the actual hardware. By late next spring, we will have hardware and then spend next summer focused on satellite-level qualification for launch readiness in late 2021.”
