1. Developed from. McDonnell Douglas F/A-18 Hornet. The X-53 Active Aeroelastic Wing ( AAW) development program is a completed American research project that was undertaken jointly by the Air Force Research Laboratory (AFRL), Boeing Phantom Works and NASA 's Dryden Flight Research Center, where the technology was flight tested on a modified ...
The Rockwell-Messerschmitt-Bölkow-Blohm X-31 is an experimental jet aircraft designed to test fighter thrust vectoring technology. It was designed and built by Rockwell and Messerschmitt-Bölkow-Blohm (MBB), as part of a joint US and German Enhanced Fighter Maneuverability program to provide additional control authority in pitch and yaw, for significantly more maneuverability than most ...
1. The Douglas X-3 Stiletto is a 1950s United States experimental jet aircraft with a slender fuselage and a long tapered nose, manufactured by the Douglas Aircraft Company. Its primary mission was to investigate the design features of an aircraft suitable for sustained supersonic speeds, which included the first use of titanium in major ...
Tecnam P2006T. The NASA X-57 Maxwell was an experimental aircraft developed by NASA, intended to demonstrate technology to reduce fuel use, emissions, and noise. [ 2] The first flight of the X-57 was scheduled to take place in 2023, but the program was cancelled due to problems with the propulsion system. [ 3][ 4][ 5]
From the X-100 Curtiss-Wright developed the larger X-200, of which the United States Air Force ordered two prototypes designated the X-19A. The X-19 had fore and aft high-mounted tandem wings. Each wing mounted two 13 ft (4.0 m) propellers that could be rotated through 90 degrees, allowing the aircraft to take off and land like a helicopter.
3, [11] this kind of semiconducting titanates, the conduction band has mainly titanium 3d character and the valence band oxygen 2p character. The bands are separated by a wide band gap of at least 3 eV, so that these materials absorb only UV radiation. Change of the TiO 2 microstructure has also been investigated to further improve the performance.
The Rockwell X-30 was an advanced technology demonstrator project for the National Aero-Space Plane ( NASP ), part of a United States project to create a single-stage-to-orbit (SSTO) spacecraft and passenger spaceliner. [ 1] Started in 1986, it was cancelled in the early 1990s before a prototype was completed, although much development work in ...
Bell X-5. The Bell X-5 was the first aircraft capable of changing the sweep of its wings in flight. It was inspired by the untested wartime P.1101 design of the German Messerschmitt company. In a further development of the German design, which could only have its wing sweepback angle adjusted on the ground, the Bell engineers devised a system ...
