Slocum was the last one to leave the jet, three minutes before impact. Shanle then flew the jetliner by remote control, from the chase plane. [9] Aftermath at the crash site. Note that the cockpit broke off. The jetliner hit the ground at 140 miles per hour (120 kn; 230 km/h), with a descent rate of 1,500 feet per minute (460 m/min). [10]
N833NA, the Boeing 720 aircraft involved in the test. NASA and the Federal Aviation Administration (FAA) conducted a joint program for the acquisition, demonstration, and validation of technology for the improvement of transport aircraft occupant crash survivability using a large, four-engine, remotely piloted transport airplane in a controlled impact demonstration (CID).
Plume shapes can be influenced by flow in the ambient fluid (for example, if local wind blowing in the same direction as the plume results in a co-flowing jet). This usually causes a plume which has initially been 'buoyancy-dominated' to become 'momentum-dominated' (this transition is usually predicted by a dimensionless number called the ...
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 United States and German Enhanced Fighter Maneuverability program to provide additional control authority in pitch and yaw, for significantly more maneuverability than ...
The first X-29 took its maiden flight on 14 December 1984 from Edwards AFB piloted by Grumman's Chief Test Pilot Chuck Sewell. [2] The X-29 was the third forward-swept wing jet-powered aircraft design to fly; the other two were the German Junkers Ju 287 (1944) and the HFB-320 Hansa Jet (1964). [ 9 ]
In aerobatics, the cobra maneuver (or just the cobra), also called dynamic deceleration, [1] among other names (see § Etymology), is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose momentarily to a vertical and slightly past vertical attitude, causing an extremely high angle of attack and making the plane into a full-body air brake ...
At a speed of about 767 miles per hour, depending on temperature and humidity, a moving object will break the sound barrier. It was not until World War II, when aircraft started to reach the ...
The V-Jet II had an all-composite structure with a forward-swept wing, a V-tail, each fin of which was mounted on the nacelle of one of the two engines. Williams had not intended to produce the aircraft, but it attracted a lot of attention, and Eclipse Aviation was founded in 1998 to further develop and produce the aircraft.
