NASA proposes Water Walls to replace mechanical life support systems
NASA proposes Water Walls to replace mechanical life support systems:
When they’re living aboard spacecraft, astronauts presently rely on mechanically-driven life support systems. Not only is there a danger of these systems breaking down, but maintenance can be challenging, as they’re always in use. While redundant duplicate systems could take over in such situations, they add to the expense and weight of a spacecraft, and also take up valuable space. Instead, NASA is exploring another possibility – the passive “Water Walls” system, which would use the principle of forward osmosis to perform tasks such as water filtration, air filtration, and even food growth...

Safer, cleaner and lighter: DLR demonstrates developments for the aviation of tomorrow at ILA 2012
Artificial bird for bird strike test
Negative swept angle in wings
Morphing Leading Edge
Microscopic holes in the outer skin of an aircraft, wings with elastically deforming leading edges and steep approach flights - these are just some of the innovations from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) for the future of aviation, offering greater comfort and safety while simultaneously consuming less fuel and generating less noise. At the ILA Berlin Air Show 2012, from 11 to 16 September, DLR is presenting a total of 18 spectacular developments in modern aviation research, along with three aircraft and two helicopters from the largest civilian research fleet in Europe. A Quadrocopter-Parcours will tempt visitors to have a go at flying themselves.
Eco-efficient flight
An aircraft as elegant as a bird of prey, with wings extended forwards in the air: DLR has been researching this wing configuration in the LamAIR (Laminar Aircraft Research) project, which will lead to a significant reduction in air resistance and thus fuel consumption. In addition, under the same project, the researchers have developed a vertical stabiliser with a microperforated outer skin, within which a pump system sits. Turbulence is siphoned through these microscopic holes, creating uniform fuselage flow.
Lower flow resistance is also the goal in the development of the droop nose, a seamless, flexible wing leading edge that can be seen as a moving original part at the DLR stand (Hall 4, Stand 4301). DLR is also demonstrating the optimum combustion of alternative fuels for aviation based on gas (GtL, Gas to Liquid) and biomass (BtL, Biomass to Liquid), with two flames for comparison. DLR researchers are presenting compressor blades with flow-optimised edges for an engine that is more economical with regard to fuel consumption.
Another development towards aircraft with lower emissions is lightweight construction. DLR is working on stiffened panels made of carbon-fibre-reinforced plastic (CFP) that are used in load tests for the material. Another exhibit demonstrates the thermography developed by DLR as a new method for testing CFP materials in an automated manufacturing process.
Flight technology for greater comfort and safety
In the Multiple Swashplate System (META), DLR researchers have developed a new technology for controlling rotor blades individually. This limits rotor noise and vibration. DLR is presenting a fully mobile, functioning META demonstrator at ILA. In addition, a new cooling system for aircraft (Cooling Center) that is positioned centrally in the tail section is being demonstrated.
The newly-developed DLR propeller brake disk can get very hot. It is made of fibre-ceramics that can withstand high thermal loads. Aircraft propellers can be stopped more quickly after landing using this technology. This limits loading and unloading times. The search for the right material is also important in the development of an artificial bird. Tail sections, wing leading edges and engines have to withstand the risk of bird strike. The DLR artificial bird will be used in tests and the approval process of new aircraft components in the future.
Unmanned disaster relief
For the first time, DLR is demonstrating the small unmanned superARTIS research helicopter, used to develop demanding automated flight missions. superARTIS stands out because of its high payload capacity, range and flight speed.
DLR is also displaying images of a disaster operation in Cyprus, where DLR scientists investigated a heavily damaged power station using an unmanned octocopter and quadrocopter. A DLR_School_Labs Quadrocopter-Parcours invites visitors to the booth to have a go at controlling the unmanned aircraft themselves.
Air traffic efficiency
DLR researchers want to achieve greater environmental sustainability and less noise from air traffic using optimised flight paths. Modern satellite navigation systems will make future flight paths more flexible. An animation demonstrates potential, steeper, more oblique approach flights. Also based on satellite data is a new system for short-term weather forecasting for air traffic. The process developed at DLR can detect weather cells in real time every five minutes and make predictions of up to an hour.
Flawless air traffic control requires personnel with the right nerves - visitors can have a go at a few aerospace psychology selection tests at the DLR booth. Anyone fancy being a pilot or flight controller? In addition, a simplified version of the indoor navigation system used at airports - using a smartphone app and QR code - is being demonstrated, as is a software package that calculates the connection of an airport to the international air traffic network in real time.
Part of the DLR research fleet will also be on display at ILA 2012. Five examples from the largest European fleet of civilian research aircraft and helicopters are set to impress visitors at the open-air grounds of the new exhibition area: the Antares DLR-H2 hydrogen power glider, the Falcon 20E, the Cessna 208B Grand Caravan 'flying auditorium' and the lightweight BO-105 multipurpose helicopter and EC-135 FHS flying helicopter simulator.
A particular highlight will be a visit by the A300 ZERO-G parabolic flight aircraft. A parabolic flight uses steep flight manoeuvres to achieve around 22 seconds of virtual weightlessness for experiments in weightlessness research.
The International Forum for Aviation Research (IFAR) is being hosted at the DLR booth in Hall 4. The Forum was founded in 2010 by initiative of DLR and, with 21 institutions involved at present, is the only network for aviation research organisations in the world.
All the exhibits with photographs and background information can be found on the DLR website dedicated to the ILA Berlin Air Show 2012.

Air travel of the future – aircraft with no leading-edge slats will be quieter and more environment-friendly
Every year, there is a six percent increase in the volume of air traffic. To make air travel more environment-friendly and quieter, researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), together with partners Airbus, EADS Innovation Works and Cassidian Air Systems, have been carrying out research to reduce the aerodynamic drag of aircraft and have developed an alternative to the traditional leading-edge slat. A morphing leading edge is expected to replace slats to create an innovative high-lift system. This construction significantly reduces drag and noise during landing. Tests were carried out between 27 August and 7 September in one of Europe's largest wind tunnels at the Russian Central Aerohydrodynamics Institute’s (TsAGI) Zhukovsky research facility south of Moscow.
In the wind tunnel, the system's operation and performance were tested under realistic conditions. "The measurements on the droop nose here at TsAGI are just one example of the exceptional collaboration between DLR and TsAGI. We are looking forward to future cooperation," said Sergey L. Chernyshev, Executive Director of TsAGI. Normally, the flaps on the trailing edges of the wings and the slats located on the leading edges are extended during take-off and landing to provide the necessary lift at low speeds. There is a gap between the wings and the slats, through which air can flow from the underside of the wing to the top – generating noise. With the development of the smart droop nose, a morphing wing leading edge, the researchers have solved this problem. "The smart droop nose morphs itself during take-off and landing in such a way that no separate slats are necessary. The leading edge can be lowered by up to 20 degrees with virtually no loss of lift," explains DLR project leader Markus Kintscher from the DLR Institute of Composite Structures and Adaptive Systems in Braunschweig.
Uniting conflicting requirements
The researchers also want to minimise drag to reduce fuel consumption. To do this, the wing surfaces have been made as flat as possible to achieve laminar airflow. This reduces the air resistance by up to 12 percent. "The particular challenge in this project was to unite conflicting requirements," explains DLR Department Head Hans-Peter Monner. "On the one hand, the structure needs to be very elastic, to enable it to morph to the required shapes, but on the other it has to be very rigid. Ultimately, the leading edge must bear around one third of the weight of the aircraft during landing." A suitable material was required to ensure that the leading edge of the wing is not too heavy. During their experiments, the researchers concentrated on the glass- and carbon-fibre reinforced composites that are typically used in the aviation industry. A glass-fibre reinforced material turned out to be the most suitable for meeting the requirements.
In the concept of the droop nose, the skin on the front edge of the wing is just curved, not stretched. This stresses the material as little as possible. The scientists position individual layers one on top of the other, in such a way that the skin creates a structure that has a customised rigidity distribution. The leading edge morphs into the desired shape via integrated actuators and support elements along the wingspan, thus achieving very high stability. Soon, the new wing leading edge will be further developed to meet industrial requirements such as lightning protection, de-icing and the ability to withstand bird strikes.

Morphing leading edge reduces drag and noise in takeoff and landing:
Passengers looking out the window of a passenger plane will likely have noticed slats on the leading edge of the wing, along with the flaps on the trailing edge of the wing, being extended during takeoff and landing. These leading edge slats provide the lift necessary at low speeds, with the gap between the wing and the slats directing air from the underside of the wing to the top. Unfortunately, this gap also generates a lot of noise. A team of researchers has now developed a morphing leading edge that eliminates the gap and reduces noise and drag during landing...
