The brand new 5th-generation fighterjet Shenyang J-31 – or F60, which would be nicknamed Gyrfalcon – took off on October 31, 2012. She thus performed a test flight – probably her maiden flight – on Wednesday.
This futuristic PLAAF (People’s Liberation Army Air Force) stealth multirole jetfighter looks like an F-35 Lightning II though the Gyrfalcon (or Falcon Eagle?) turns out to be a twin-engine a/c. She would be more maneuverable but smaller than the latest Chengdu J-20 Black Eagle stealth fighter. Her radar cross section (RCS) might be very small, and stealthier than recent 5th-generation fighter aircraft as the radome mounting looks as if it were – like the rest of the airframe – designed with reentrant shapes.
This fighter aircraft would not exceed Mach 2, and she features a DSI (Diverterless Supersonic Inlet) so that the airspeed can be reduced while entering the air intake, thus preventing the engine from breaking up.
Felix Baumgartner, the famous Austrian skydiver, is still waiting for better meteorological conditions to make a new attempt in the Red Bull Stratos project to break the sound barrier while freefalling. This new feat might happen within the next few days as it has already been scheduled on October 14.
According to the video below, Felix BAUMGARTNER’s top 5 jumps are:
Wingsuit Channel Crossing
Taipei 101 BASE Jump
Petronas Towers BASE Jump
Seating of the Spirits Cave Jump
Man vs. Plane
Felix BAUMGARTNER was to jump on the 9th of October 2012. However, this jump which could have become the highest skydive in the aerospace history has been put off due to gusty winds.
In this new record attempt Felix BAUMGARTNER will be so high up – 120,000 ft, or 36.6 km – that if his suit leaks, his blood will boil. When he jumps, he will fall so fast that he will break the sound barrier as explained in this video:
A 3-hour ascent is expected to reach such an altitude, and it could take him more than a quarter of an hour to fall down back to the earth, and land… And now the animation on how it could unfold from the stratosphere right over Roswell, New Mexico, USA: (Click on the link below – MUST SEE!)
This is what the next Airbus aircraft should be in the 40 years to come. The new Airbus concept is to match the passengers’ demand.
According to a consultation with the customers, 96% of them want more environmentally sustainable aeroplanes. The aircraft of the future will have to be fully recyclable, more sustainable ie eco-efficient, and less stressful:
Now, the leading aircraft manufacturer is using the feedback to paint its vision of sustainable aviation in 2050.
There is a need among the passengers to reduce the time spent in airports. The new Airbus concept cabin will integrate an additional door for faster boarding, and exit. This airliner of the future will reduce its noise, and carbon emmissions. It will use the latest technologies – bionic structure, blended airframe, enhanced laminar flow and noise reduction; blended U-tail, biomorphing seats able to collect the passenger’s body energy, cutting-edge relaxation systems, human body thermal recycling, dramatic panoramic view, World Wide Web access, round of golf, etc. Watch the video:
NASA Langley Research Center in Hampton, Virginia – New energy-efficient airplanes could be designed. Researchers work on designs for viable commercial aircraft which could leave a low to zero carbon footprint.
In order to save jet fuel, they look at new concepts, processes, and designs that could be lighter. They try to reduce drag, and they try to increase the propulsive efficiency. For this purpose, they try to get rid of metallic airframes, and parts as often as possible.
For instance NASA has a newer composite 10 percent lighter than carbon fiber composite. This advanced material is called « Pultruded rod stitched efficient unitized structure » or PRSEUS.
The new sleeker designs look like large wings without any traditional tube-shaped fuselage in the central part since it is blended with the wings. These futuristic designs are more fuel efficient as the more lift the plane has, the less it consumes fuel.
The researchers also look at new energy sources as it is showed in this video, and in the end there is further information about the NextGen project which could save fuel too, thanks to this new form of air traffic management:
Felix Baumgartner, an Austrian skydiver, performed a challenging test jump on Thursday March 15, 2012.
Felix Baumgartner has the right stuff. He is a well known BASE jumper. B.A.S.E. means Buildings; Aerials; Spans (jumps from bridges); and Earth (jumps from cliffs). He performed numerous stunts such as jumping from the Petronas Towers in Kuala Lumpur, the statue of Christ the Redeemer in Rio de Janeiro, World Financial Center T101 in Taipei, and the Millau viaduct.
Yesterday’s jump test is just a stage in his attempt to break a new free-fall record. He jumped above Roswell, New Mexico at an altitude of 71,581 feet ie 21.8 kilometers; 13.6 miles; or Flight Level 716. He should then carry out another jump test before leaping again from a capsule lifted by a helium balloon at around 120,000 ft ie 23 miles or 37 km this year, and could become the first man to break the sound barrier while free falling.
This is not a simple leap in the sky. People may not understand how dangerous skydiving at such heights is. The air density is so low that it cannot brake movements as drag becomes poorer up there.
Therefore, a position mistake can make the human body tumble violently or spin very fast. High rotation speeds involve high-G forces due to the centrifugal force, and may lead to G-LOC (G-force induced Loss Of Consciousness), and even to the rupture of blood vessels.
Moreover, if a spacesuit were to leak (due to a dormant seal failure or a cracked/crazed faceplate, for instance), the blood could be boiling (ebullism at 37°C above 63,000 ft or 19 km) because of the very low air pressure, and the body could be swelling, and actually freezing to death as the external temperature can reach down to -70°C, and even lower, not to mention the risk of pulmonary barotrauma.
The current record is held by Joseph Kittinger (a former USAF pilot who is curently advising Felix Baumgartner on his project) who jumped from 102,800 feet in 1960. He temporarily lost the use of his hand which got twice as big as a glove seal was leaking during the final part of the ascent. With this test jump, Felix Baumgartner already belongs to the highest three skydivers along with Joe Kittinger, and Russian Eugene Andreev who performed the longest parachute jump from 83,523 feet (25.5 km).
The following video shows that this feat is not only a matter of pushing limits as researchers are working on this Red Bull Stratos project to prepare flight safety of the future spacecraft:
