RR test composite made Low Pressure System (fan blades, a fan case and annulus fillers)

martes, 26 de febrero de 2019

press release

Engineers at Rolls-Royce in Derby, UK, have successfully tested a key component of the UltraFan engine design. UltraFan will redefine the world of jet engines, delivering significant weight, noise and fuel burn reductions, and will be 25% more efficient than a first-generation Trent engine.

For the first time, all composite elements of the Advanced Low Pressure system (ALPS), including fan blades, a fan case and annulus fillers, were tested together on a donor engine.

The engine parts are manufactured using state-of-the-art, fully automated construction methods at Rolls-Royce’s Composites Technology Facility, a Composites Centre of Excellence.

Each fan blade is made robotically, building up around 500 layers of carbon fibre materials. Heat and pressure are then applied, and each blade is finished with a leading titanium edge, which offers extreme protection against foreign objects and bird strikes. When laid out, the layers of composite material that make up the fan blades and the fan case on this engine would stretch from London to Leeds.

The Advanced Low Pressure System demonstrates Rolls-Royce’s IntelligentEngine vision. Each blade has a digital twin – an identical virtual copy. During testing, vast amounts of data will be collected that will be fed into the digital twins, and allow engineers to predict how each blade will perform in service.

Ash Owen, Rolls-Royce, Chief Engineer, Civil Aerospace Demonstrator Programmes said: “These incredible technologies are taking our world-leading fan efficiency to the next level. More than a decade of research and development has brought us to this point and I’m confident that after extreme weather testing in Canada and performance testing in Germany, we can prove ALPS technology even further here in Derby, moving us one step closer to our UltraFan demonstrator.”

The Advanced Low Pressure System programme is a partnership between Rolls-Royce, Clean Sky, Innovate UK, the Department for Business, Energy and Industrial Strategy, the Aerospace Technology Institute, ITP Aero and GKN.

TsAGI and Rosteck test full scale 3 blade rotor for new light multi-purpose helicopter with coaxial rotors

press release

Specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center “Zhukovsky Institute”) together with the Design bureau “VR-Technologies” of the Russian Helicopters (State Corporation Rostec) conducted the second stage testing of the VRT500 rotor, (the VRT 500 is the light multi-purpose helicopter with coaxial rotors).

The full-scale hingeless rotor model was tested in the largest Europe wind tunnel — the TsAGI’s subsonic wind tunnel. The Institute’s scientists studied the behavior of the model at speeds up to 136 km/h during the tests. The collective pitch angle was varied within the functional range, at the same time there were applied longitudinal design and lateral control systems. Specialists continuously recorded the measured data, including forces and the moments affecting the model in general, and loads for the three sections of one of the blades.

The experiment confirmed the previously calculated aerodynamics and aeroelasticity of the rotor and its blades. The results will help to clarify flight characteristics of the helicopter. “The VRT500 project’s tests were successful and turned out to be very interesting for us,” noted Oleg Kirillov, the Chief of the Department of aerodynamics and dynamics of helicopters. “First of all, we tested a full-scale model, and it was already a unique situation. Secondly, we had to deal with a hingeless rotor model. The design of this kind has been poorly studied in Russia yet; it was only used for the ‘Ansant’ helicopter. These works appeared to be exceptionally relevant to the development of the research competencies and design of hingeless rotors in TsAGI.”

The VRT500 is a light single-engine helicopter with twin three-blade coaxial rotors. Its takeoff weight is 1600 kg. The machine has the largest-in-its-class passenger/cargo cabin for up to 5 people and is equipped with a modern, interactive avionics complex. Its flight characteristics enable the helicopter to reach speeds of up to 250 km/h, flying at a distance of up to 860 km, taking on-board up to a 730 kg payload. The helicopter is intended for passenger, multi-purpose, commercial, educational, VIP and medical operations.

ESA: Signs of ancient flowing rivers on Mars

We see Mars as a cold, dry world, but plenty of evidence suggests that this was not always the case. Research in past years instead increasingly indicates that the planet once had a thicker, denser atmosphere that was able to lock in far greater amounts of warmth, and therefore facilitate and support the flow of liquid water on the surface below.  Continue reading:

Hybrid fiber combines strength of metal core and elasticity of rubber shell


Tough, biological materials (e.g., collagen or titin) protect tissues from irreversible damage caused by external loads. Mimicking these protective properties is important in packaging and in emerging applications such as durable electronic skins and soft robotics. This paper reports the formation of tough, metamaterial-like core-shell fibers that maintain stress at the fracture strength of a metal throughout the strain of an elastomer. The shell experiences localized strain enhancements that cause the higher modulus core to fracture repeatedly, increasing the energy dissipated during extension. Normally, fractures are catastrophic. However, in this architecture, the fractures are localized to the core. In addition to dissipating energy, the metallic core provides electrical conductivity and enables repair of the fractured core for repeated use. The fibers are 2.5 times tougher than titin and hold more than 15,000 times their own weight for a period 100 times longer than a hollow elastomeric fiber.

Figure 1B compares the force versus strain responses of a solid gallium rod, an empty SEBS fiber, and a Ga-SEBS metamaterial fiber (see fig. S2 for stress-strain data). In Fig. 1B, each sudden decrease in force corresponds to a break in the metallic core of the Ga-SEBS fiber, after which a polymer bridge forms from the encasing polymer. After each break, the force needed to maintain a constant rate of extension increases steadily as the bridge is strained, until eventually the metallic core fractures again and the cycle repeats itself. During these cycles, the strain localizes primarily in the polymer bridges between the breaks, which keeps the overall stress high regardless of the macroscopic strain. This behavior generates a sawtooth-shaped curve centered about the force needed to break the metallic core (see note S1 for additional details) and provides an effective and continuous energy dissipation method. The fiber sustains approximately the same force as the force needed to break the metallic core, but for almost six times the amount of strain.

Airbus Friedrichshafen triples the size of its integration facilities

Press release

Airbus’ Friedrichshafen site has opened Europe’s most state-of-the-art satellite integration and space technology centre, known as the Integrated Technology Centre (ITC). The ITC, which triples the area of clean room space to 4,200 m2, is dedicated to building satellites, probes, space instruments and experimental technologies. The centre took only two years to build at a total cost of approximately €45 million.

“Airbus’s significant investment in this building also represents an investment in the future – both for the Airbus site at Lake Constance and for Baden-Wuerttemberg as an aerospace location. When it comes to space technology, we are now a step ahead of the rest of Germany – in terms of science and research, development and technology, and enthusiasm for the aerospace industry,” said Baden-Wuerttemberg’s Minister-President, Winfried Kretschmann. “With this technology centre, Airbus has shown it has the courage to take the leap into a new age of even better satellites, and this includes those intended for scientific purposes. Satellites can, for instance, document changes in sea levels and detect even small sources of greenhouse gas emissions. Satellites of this nature are helping to expand the basic scientific knowledge needed to combat climate change.”

“Space flight has undergone huge positive development over the past few years. In addition to scientific missions to explore our solar system and investigate fundamental physical laws, we as a space company are meeting a swiftly increasing demand for high-performance, ultra-reliable Earth observation, meteorological and navigation satellites,” said Nicolas Chamussy, Head of Airbus Space Systems. “Thanks to the new satellite hub, production at Airbus’s Friedrichshafen site is optimally positioned in terms of both quality and quantity compared with our competitors.”

With dimensions of 70 x 60 metres and a ceiling height of up to 18.50 metres, the building was designed to expand the current satellite integration hall. The new ‘dual’ complex enables projects to be executed more efficiently and economically and, thanks to cutting-edge technology and its new size, also offers new possibilities for developing future space projects, such as large space telescopes.

The centrepiece of the ITC is its large clean room. The final integration of the satellites takes place under clean room conditions of various ‘cleanliness classes’ (from ISO 8 to ISO 5) in facilities totalling approximately 2,100 m2, of which 400 m2 are dedicated to ISO 5. Extensive air conditioning and filter systems circulate an air volume of 900,000 m3 up to 60 times an hour, which not only ensures the required levels of cleanliness but also a consistently elevated air pressure, in addition to controlling humidity and temperature.

Four seismic blocks, each weighing 150 tonnes, ‘decouple’ special integration tables from the building and ensure a completely vibration-free environment for the installation of optical instruments. A computer-controlled fan and filter matrix on the south side of the clean room generates air-flow profiles that can be adjusted to the occupancy of the room. This concept allows different clean room classes to be created in a single hall with no disruptive partitions or curtains.

In the adjacent check-out rooms, technicians can conduct a broad array of electrical function tests without having to enter the clean room area. All computer systems are housed in their own air-conditioned, noise-insulated racks.

The two wings of the ITC provide a further 1,100 m2 of integration and laboratory space for component manufacturing and technical areas. The first floor of the building’s west wing houses a conference zone and a multifunctional showroom and information space, whose large panoramic windows provide a unique view of the flight hardware production process.

Four Sentinel satellites for the European environment and security programme ‘Copernicus’, the joint European-Japanese EarthCARE Earth observation satellites and two 12.30-metre-long planar radar antennas are the first projects to move into the new centre. The integration work for JUICE, a mission to the icy moons of Jupiter (set to launch in 2022), is also expected to start within the next six months.
