Exposición bibliográfica: 75 años del Ejército del Aire desde los libros
Las primeras ascensiones militares de globos en España tienen lugar en el siglo XVIII, y el primer vuelo militar se produce en febrero de 1911. Son los ingenieros militares quienes están al tanto de todos estos desarrollos participando en su evolución. Así la aviación en España va muy ligada al mundo militar desde sus inicios. Coincidiendo con los primeros vuelos van apareciendo en rápida sucesión nuevos descubrimientos propiciados por la revolución industrial, nuevos usos de la electricidad, el desarrollo de los motores de explosión, la fotografía, o las nuevas rotativas para la impresión de libros, revistas y periódicos.
Es por esto que el desarrollo de la aeronáutica es uno de los más documentados ya que la mezcla de técnica, riesgo y la posibilidad de alcanzar nuevos límites o “récords” volando más rápido, más alto o más lejos generó un enorme interés por parte de los ciudadanos, lo que contribuyó a una mayor difusión de la temática en periódicos o revistas.
En 1927 se crea el Consejo Superior de Aeronáutica, dependiente del Ministerio de Presidencia, y se le dota de una Biblioteca que se encarga de reunir la actualidad aeronáutica y todo lo escrito anteriormente desde los inicios de la aviación. Ése es el origen de la actual Biblioteca Central del Cuartel General del Ejército del Aire.
Los fondos exhibidos en esta exposición pertenecen a la mencionada biblioteca, y pretenden ser una muestra del desarrollo de la Aviación en España, tanto a nivel civil como militar, mostrando también las publicaciones que han emanado del Ejército del Aire, difundiendo sus actividades, sus misiones, sus aviones, su personal, sus uniformes y en definitiva, todo lo que le es propio. Todo queda reflejado en los documentos que se presentan, de los aviones de madera y tela, a los de titanio, mostrando más de 100 obras, entre libros y revistas, principalmente.
La Exposición titulada "75 años del Ejército del Aire desde los libros", se enmarca dentro de las múltiples actividades programadas para la celebración del 75 aniversario de la creación del Ejército el Aire.
La Biblioteca Central se encuentra situada dentro del Cuartel General del Ejército del Aire y está abierta al público, siendo un referente en cuanto al estudio de la historia de la aviación en España se refiere.
- Fechas: Del miércoles 19 de febrero al domingo 2 de marzo de 2014.
- Lugar: Vestíbulo principal del Cuartel General del Ejército del Aire.
- Plaza de la Moncloa, sin número (entrada por calle Princesa), Madrid.
- Horario: De Lunes a Domingo, de 10:00 a 18:00.

Desarrollan un nuevo sistema de pinturas para aviones más ecológico
// Instituto de la Ingeniería de España
Desarrollar un nuevo sistema de pinturas para aviones más ecológico, que evite la corrosión, es el objetivo del proyecto europeo de investigación GreenGELAIR, en el que participan científicos de la Universidad Carlos III de Madrid.
Desarrollar un nuevo sistema de pinturas para aviones más ecológico es el objetivo del proyecto europeo de investigación GreenGELAIR, que ha arrancado recientemente y en el que participan científicos de la Universidad Carlos III de Madrid (UC3M). Los resultados del proyecto podrán ser aplicados en otros sectores, además del aeronáutico.
El proyecto GreenGELAIR, señala la nota de prensa de la UC3M, trata de resolver un problema que actualmente presentan las pinturas utilizadas en diversas industrias. Estas pinturas contienen cromo hexavalente y, según las regulaciones medioambientales, deben sustituirse por otras en la mayoría de los sectores, particularmente en el aeronáutico.
Los investigadores del Departamento de Ciencia e Ingeniería de los Materiales de la UC3M están diseñando una nueva formulación y un nuevo sistema de aplicación para recubrimientos de pintura basados en la tecnología sol-gel.
A partir de moléculas compuestas de oxígeno, silicio, hidrógeno y carbono se producen determinadas reacciones químicas que llevan a la formación de una red polimérica capaz de albergar inhibidores de la corrosión ecológicamente aceptables. Esta tecnología, además, conlleva otras ventajas, como la utilización de disolventes no tóxicos y la oportunidad de trabajar a temperatura ambiente.

Mach 4 Bizjet Not Hard Enough? Try This...
----
Mach 4 Bizjet Not Hard Enough? Try This...
// Things With Wings
If you have heard of Richard Lugg, you probably know him as the man behind the HyperMach SonicStar supersonic business jet concept. And as if Mach 4 cruise, supersonic laminar flow, plasma drag and boom reduction, and superconducting electric propulsion were not enough, Lugg’s name appears on a new US patent (8,636,241, filed in 2006) for a hybrid jet/electric VTOL aircraft.
Graphics: USPTO
The design uses electric-powered lifting fans in the wing roots and canard foreplanes for vertical flight. The fans are powered by electricity generated by turbofans, which provide propulsion in forward flight. In vertical flight, residual thrust from the turbofans is vectored downwards to supplement lift from the fans. In forward flight, all engine power goes to thrust and louver doors close over the fans.
How much engine thrust needs to be vectored depends on the power of the lifting fans, which can range from 25% to 100% of the lift needed for VTOL, the patent says. The advantage of the fans is their exhaust flow is at ambient temperate and low velocity. The power extracted from the turbofans to generate electricity also reduces the temperature and velocity of the vectored engine thrust, allowing the aircraft to operate from unprepared surfaces, the patent claims.
Not surprisingly, there are echoes of the SonicStar and its SonicBlue H-Magjet (Hypersonic-Magnetic Advanced Generation Jet Electric Turbine) engine in the VTOL concept. In the H-Magjet, the fan and compressor stages are driven electrically from a superconducting generator embedded in the turbine, which is driven by burning fuel. This eliminates the shafts within a conventional turbofan and allows each individual stage to run at its optimum speed.
In the hybrid jet/electric VTOL concept, the turbofan drives a generator, “preferably superconducting”, attached to the turbine shaft via an electric clutch, producing megawatts of electrical power. Each fan is magnetically centered within a superconducting magnetic coil that drives it at speeds of 3,600-8,500rpm. Each has its own speed controller and, in a 10-fan aircraft, six are used for lift while four (in the canard) are also used for attitude control in vertical flight, the patent says.
SonicStar (Concept: HyperMach)
HyperMach raised more than eyebrows when it unveiled the SonicStar concept in 2008 – its hybrid-electric jet propulsion and plasma-aerospike flow control seeming more science fiction than feasible technology. The company says it continues to refine the design, and look for a manufacturer to develop and build the aircraft. It hopes to fly by 2024, but no-one is holding their breath.The hybrid jet/electric VTOL design looks a bit more practical and, if not Lugg’s design, then some similar form of distributed-thrust, electric-propulsion VTOL is going to fly sooner rather than later, I am sure.

El presidente de Airbus tacha de “hipócrita” la postura de Boeing con las ayudas al B-777X
// Revista de prensa aeronáutica: Feed de feeds de Revistas Aeronáuticas | recopiladas por www.noticias-aero.info
“Tremendamente hipócrita”. Esta es la expresión que el presidente y consejero delegado de Airbus, Fabrice Brégier, utilizó para describir
Preguntado sobre las diferencias entre estas exenciones fiscales y las ayudas que está recibiendo su propia empresa por la instalación de una FAL en Mobile, Estado de Alabama, Brégier precisó que: “La diferencia es que en Estados Unidos es legal que cuando inviertes en una nueva industria en un sitio recibas ayudas para formación u otras actividades. Esto es un apoyo clásico y normal que hay en todos los países. Lo que no es normal es que tengas que invertir 5.000 millones de dólares en el desarrollo del nuevo B-777X, y obtengas a cambio 8.700 millones de dólares en exenciones de impuestos. Esto parece un poco extraño. Este sistema se usó ya en el B-787 y fue declarado ilegal. Por eso sabemos que lo es, no es que lo digamos nosotros. Boeing fue el que denunció el tema ante el WTO y fue a la que declararon las ayudas ilegales. Pero esto parece no importar. No puedes cambiar las reglas cuando quieras.”

Iberdrola Ingeniería acaba de lanzar, en colaboración con un grupo de empresas vascas, el proyecto de I+D denominado Marin-el, cuyo objetivo es diseñar un nuevo modelo de subestación marina para parques eólicos offshore que facilite su instalación y logre abaratar significativamente los costes.
La iniciativa, que cuenta con un presupuesto de 10 millones de euros y el respaldo del Gobierno vasco, también pretende ofrecer una alternativa a las actuales subestaciones, demasiado voluminosas y pesadas. Este tipo de instalaciones marinas, informa la compañía en una nota de prensa, debe cumplir requisitos cada vez más exigentes, derivados no solo de la creciente potencia nominal de los parques eólicos offshore, sino de la necesidad de gestionar una energía eléctrica fiable y de tratar de reducir al mínimo las pérdidas provocadas por la lejanía de estas infraestructuras de la costa.
La propuesta cuya viabilidad técnica y económica va a analizar Marin-el se basa en la creación de una subestación autoinstalable que implicaría todo tipo de ventajas: tanto en la fase de construcción, dado que ésta se desarrollaría al 100% en tierra firme, como en las de transporte y, sobre todo, montaje. Su fijación al fondo marino no precisaría de la ayuda de barcos-grúa especiales, como sucede en la actualidad, que encarecen el proceso y tienen numerosas limitaciones técnicas.
Marin-el se desarrollará en principio hasta finales de 2015.

Europe Looks for Lead in Fast Rotors

Europe Looks for Lead in Fast Rotors
// Things With Wings
Europe's rotorcraft industry has high hopes for the planned Clean Sky 2 public-private research program. Clean Sky 2 is expected to include not one, but two fast rotorcraft flight demonstrators, one led by AgustaWestland and the other by the company formerly known as Eurocopter (now Airbus Helicopters).
Clean Sky 2 is planned to run from 2014 to 2023 with €4.05 billion ($5.55 billion) in funding -- €1.8 billion from the European Union and the rest from industry. For both manufacturers, the program is a chance to keep pace in fast-rotorcraft development with the U.S., which plans to fly two demonstrators under the Army's Joint Multi Role (JMR) program.
As Clean Sky managers tour Europe briefing industry and academia on the plans for Clean Sky 2, now in the political approval phase, leaders of the proposed fast-rotorcraft integrated aircraft demonstrator program (IADP) are providing glimpses into the different objectives behind the two vehicles they plan to fly before the end of this decade.
Outer wings and proprotors tilt, engines remain fixed (Concepts: Clean Sky)
AgustaWestland will lead design of a second-generation tiltrotor -- the first generation being the company's AW609, a design acquired from former partner Bell Helicopter. The flight demonstrator will aim to validate a tiltorotor configuration in which the outer wing panels tilt with the proprotors while the inner wing sections stay fixed. The engines may or may not remain fixed while the proprotors tilt.
This configuration promises to increase efficiency in both helicopter and aeroplane modes, allowing a longer-span wing for lower drag in cruise flight while minimizing rotor download on the wing in vertical flight. Karem Aircraft uses a similar approach in its tiltrotor for JMR, while Bell uses fixed engines/tilting proprotors in its design for the US Army program.
Or tip-mounted nacelles tilt with outer wings (Concept: Clean Sky)
AgustaWestland is aiming for a cruise speed exceeding 300kt, allowing the pressurized aircraft to fly 250nm in under 1hr 45min on search-and-rescue and medical missions. The proposed schedule calls for a critical design review in first-half 2016, demonstrator first flight in mid-2019, reaching TRL 6 by the end of 2022 ready to transition to a certification program beginning in 2033.
Airbus Helicopters' concept artwork for the second fast-rotorcraft demonstrator, LifeRCraft, is more generic, showing a swoopy notional follow-on Eurocopter's X3 compound-helicopter testbed. The objectives under the IADP include combining a cruise speed of 220kt with hover performance as least as good as a conventional helicopter, while lowering noise and emissions.
Tractor- (top) or pusher-prop compound configurations (Concepts: Clean Sky)
LifeRCraft has the same architecture as the X3, with two (tractor or pusher) propellers at the tips of short wings driven from the same gearbox as the single main rotor. Sikorsky's compound helicopter for JMR has coaxial rigid main rotors and a single rear propulsor, while AVX's has coaxial rotors and ducted fans. The goal under Clean Sky 2 is to take the Eurocopter/Airbus compound helicopter to TRL 6 by 2020.

Behind The Threatened F-35 Delays

Behind The Threatened F-35 Delays
// Ares
“Could have been worse” is probably a good four-word summary of the latest Joint Strike Fighter report by the director of operational test and evaluation, Michael Gilmore. If you paid attention to Gilmore’s congressional testimony on June 19 (too few people did), or to our coverage, there is little shocking news.
On the other hand, if you were confidently expecting the program to make the scheduled initial operational capability dates announced last May (too many people were), the report is a cold shower, making a strong case that those dates may be missed by a year or more.
Gilmore’s team is most specific on the first planned IOC, for the Marine Corps. The current objective date is July 2015 (objective) and December 2015 (threshold). The report predicts that the necessary software, Block 2B, will not complete developmental testing until November 2015 or be released to the fleet until July 2016, 13 months late. Since an operational utility evaluation (originally set for May 2015) will then be needed before IOC, the aircraft would not be operational with the Marines until late 2016 or early 2017.
The report also gives new detail on the strong linkage between Block 2B and Blocks 3i and 3F. Block 3i supports the US Air Force IOC (objective August 2016, December 2016) and basically re-hosts the Block 2B’s capabilities on a the new Technology Refresh 2 integrated processor, which is installed on Lot 6 and later F-35s. Block 3F provides full operational capability (that is, compliant with the key performance parameters established when the program started) for Navy IOC, with an objective of August 2018 and a threshold of February 2019. It is also the supported configuration for most international operators.
Most Block 3i/3F testing cannot start until Block 2B developmental testing is completed, which (according to the official schedule) is due to happen in October. “All program plans and schedules [for 3i/3F] depend on this happening so that the development laboratories and test venues can be converted and devoted to testing the Block 3 hardware,” the report says, but predicts that the switch will start more than a year late.
A complication is that the Lot 6 aircraft with the new processor start to roll off the production line in the middle of this year, but cannot be accepted without certified Block 3i software. To avoid the problems associated with a pile-up of grounded jets at Fort Worth, the program office is modifying three mission systems test aircraft (one of each variant) with TR-2 processors to test an early increment of 3i. However, these aircraft will then be unavailable to support Block 2B development.
Gilmore’s predictions about testing schedules are more specific than those he advanced in June, when he first noted that the then-new IOC dates were at risk. The report is based on the actual growth rate – in testing needed to accomplish specific tasks – between January and October 2013. It separates testing of the helmet-mounted display system from other things that needed more testing than predicted – “regression testing” of seven different software loads and issues with the radar and electro-optical targeting system, among others. If that historical growth rate of 40 per cent is maintained, the predicted delay will occur, the report says.
Other problems noted in the report:
One reason for delays in Block 2B was that the first training standard package for use by the US Air Force at Nellis AFB and the Marines at MCAS Yuma, Block 2AS3, was rejected by flight test teams as being unsuitable for night and instrument flying, and the program “had to make adjustments to Block 2B” while another 2A version was developed.
The first attempt to load Block 3i on an F-35C, in October, failed.
So far, the highly touted Distributed Aperture System (comprising six infra-red cameras covering an entire sphere around the aircraft, and intended to track aircraft and missiles while delivering imagery to the helmet) has failed in its most basic function as a missile warning system, being unable to tell missiles from decoy flares.
The program is still dealing with poor target track quality from the EOTS and radar, which is causing problems with demonstrating simulated weapon engagements.
Development of “enhanced diagnostics (model-based reasoning)” for the Autonomous Logistics Information System (Alis) has been cancelled for the rest of the system development and demonstration phase, because the current diagnostic system has, so far, “failed to meet basic functional requirements, including fault detection, fault isolation and false alarm rates.” (These are otherwise known as “what diagnostic systems do.”)
The reliability of the training fleet is well behind predicted levels.
Despite these and other issues, software is still the critical issue for this program, and the corrective actions taken since 2010 (including added flight test time, new laboratories and more engineers) do not seem to have resulted in a stable and predictable schedule.
The report does not go into root causes, but I believe that (ultimately) there are two big issues that will be identified.
One of these is that sensor fusion – taking targets from radar, electro-optical, passive electronic and other sensors, together with datalink information and databases, and fusing them into a single set of targets – is extremely difficult. Every program that does this has had problems, and the transition from ground-based laboratories, through a flying test bed, to real-world operations seldom goes smoothly. Unlike software-intensive ground-based computer systems, the initial inputs are unstable and unpredictable analog signals, and airborne sensor-fusion systems can’t be tested on hundreds of PCs running 24/7.
The other issue is that the F-35 system is highly integrated, with its higher functions concentrated in the integrated core processor banks in the forward fuselage. This was an architecture inherited in 1995 from the F-22, because, at the time, a shared-processor approach appeared to be the only way to provide enough horsepower for sensor fusion in a fighter aircraft. But it may mean that regression testing – that is, making sure that a change in software has not impacted another function – becomes more extensive and complicated. The need to do more regression testing than predicted has been a recurring factor in F-35 delays.
As for fixes: Is the Block 2B configuration holding the entire program up? In some ways it is clearly doing so (by hogging laboratories that are needed for 3/3i). Its military value is strictly limited: It allows the Marines to field one squadron of aircraft with a limited operational capability (they are not compatible with the Rover video datalink, near-essential for close air support, and do not have a gun or AIM-9 provisions) a year before 3i would be available. On the other hand, an early operational capability could be a valuable way of surfacing unexpected snags.
In the long run, however, what will be most important is for the program to fully understand and manage the writing and testing of software for the F-35 platform, because development does not stop with Block 3. If cost overruns, delays and the consequent deferment of new capabilities from one block to the next are not contained, there is little chance that the fighter’s sustainment will be affordable.

Will Boeing Embrace Braced WIngs?
// Things With Wings
The cover story in the latest Aviation Week & Space Technology is an exclusive on tests of Boeing's Sugar truss-braced-wing (TBW) airliner concept in NASA Langley Research Center's Transonic Dynamics Tunnel.

You can read how the expensive and flexible 13ft-span, 15%-scale model is being used to validate wing weight estimates for a full-size aircraft. These are critical to determining whether the fuel savings promised by the drag reductions possible with a high-aspect-ratio wing are achievable.
Boeing and NASA are pretty convinced the wing can be made light enough, and that a 737-size TBW airliner would have a 5-10% lower fuel burn, even with the same generation of engines. They are also pretty confident a truss-braced wing can be an option for the next generation of all-new airliners, expected somewhere around 2030.
The study work, being conducted under NASA's N+3 project, is also looking at hybrid turbine-electric propulsion for Boeing's Sugar Volt concept, and in the same issue of AW&ST you can read my colleague Guy Norris's article on General Electric's work on the hFan gas-turbine/battery-electric engine concept.

But why a high-aspect-ratio wing? Aspect ratio (span-squared divided by area) is a measure of a wing's slenderness. The more slender a wing is, the lower the lift-induced component of drag and the higher the lift-to-drag ratio (a measure of aerodynamic efficiency) -- think of a sailplane wing.
Most jetliner wings have an aspect ratio around 9. Thanks to their stiff carbon-fiber wings, the Boeing 787 and Bombardier CSeries push this to 11. With active flutter suppression and gust-load allevation to control the structural flexibility, you might get to 15 with a conventional "cantilevered" wing supported only at its roots.
To go higher and reduce drag further, to an aspect ratio of 20, or even 30, you need to support the wing with a strut (a single member) or truss (two or more members). Hurel-Dubois pioneered this with a series of designs in the late 1940s and 1950s - you can see our slideshow on the history of strut/truss-based wings here.

Hurel-Dubois' aircraft were successful technically, but not commercially. They were piston-powered and slow. To make TBW work for a future jetliner the structure must be light, and drag from aerodynamic interference between the struts and the wing must be minimized. That is what the Sugar study is working to validate.
Interestingly, the Sugar study involves not only Boeing Research & Technology but also Boeing Commercial Airplanes -- which has a tendency to keep unconventional configurations (like blended wing body) at arm's length. Perhaps its involvement with Sugar is a sign that TBW is a viable option for a future airliner.
