Mark Rober is an American YouTuber, engineer, inventor, and educator.He is known for his YouTube videos on popular science and do-it-yourself gadgets.Before he became a YouTuber, Rober was an engineer with NASA for nine years, where he spent seven years working on the Curiosity rover at NASA's Jet Propulsion Laboratory.
A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.
Two successful NASA Langley Research Center led sub-orbital flight demonstrations of HIAD technology have occurred; Inflatable Reentry Vehicle Experiment 2 (IRVE-2) [7] and IRVE-3 [8] were flown in 2009 and 2012 respectively. LOFTID is the first orbital flight of a HIAD and the largest blunt bunt aeroshell entry to date.
NASASpaceflight original reporting has been referenced by various news outlets on spaceflight-specific news, such as MSNBC, [2] USA Today [3] and The New York Times, [4] among others. NASASpaceflight also produces videos and live streams of rocket launches online, with a special focus on developments at SpaceX's Starbase facility , [ 5 ] [ 6 ...
During the early phases of the Shuttle program, NASA considered using the Boeing 737 airliner as the basis for the STA, but rejected it due to cost and opted for the less-expensive Gulfstream II. [1] The aircraft's exterior was modified to withstand the high aerodynamic forces incurred during training sorties. A redesigned cockpit provided a ...
Vortices are one of the many phenomena associated with the study of aerodynamics. Aerodynamics (Ancient Greek: ἀήρ aero (air) + Ancient Greek: δυναμική (dynamics)) is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. [1]
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 McDonnell Douglas F/A-18 Hornet.
The stalling angle of attack is less in ground effect, by approximately 2–4 degrees, than in free air. [23] [24] When the flow separates there is a large increase in drag. If the aircraft overrotates on take-off at too low a speed the increased drag can prevent the aircraft from leaving the ground.
