Demonstrate precision hover flight within a virtual two-meter diameter sphere for one minute. Demonstrate hover stability in a wind gust flight which required the aircraft to hover and tolerate a two-meter per second (five miles per hour) wind gust from the side, without drifting downwind more than one meter.
The Wingless Electromagnetic Air Vehicle (WEAV) is a heavier-than-air flight system which can self-lift, hover, and fly reliably with no moving components. The Wingless Electromagnetic Air Vehicle ( WEAV ) is a heavier than air flight system developed at the University of Florida , funded by the Air Force Office of Scientific Research .
The computer system also prevents the machine from flying higher than 10 feet (3 m) above the ground. Per Federal Aviation Administration regulations, any vehicle which flies above 10 feet is regulated as an aircraft. [1] The M200G Neuera is expected to be capable of travel over any terrain at speeds up to 50 mph (80 km/h). [4]
The aircraft is not a tiltwing or tiltrotor design. Instead, the entire aircraft changes pitch in order to fly in two modes, hovering and cruising. In hover mode, the aircraft is pitched roughly vertically and maintains its position and altitude by default, though it can move laterally and longitudinally, as well as change its heading, if ...
Replacement helicopter based on the Boeing Model 360, this Advance Technology Demonstrator from the 1980s never entered production. The aircraft relied heavily on composites for its construction and had a beefier drive train to handle the twin Avco-Lycoming AL5512 engines (4,200 shp). [53] XH-49 Original designation of UH-46B.
Chosen to replace the HH-3F Pelican, the MH-60T is a member of the Sikorsky S-70 family of helicopters and is based on the U.S. Navy's SH-60 Seahawk helicopter, [1] itself based on the U.S. Army's UH-60 Black Hawk helicopter. Development began in September 1986, first flight was achieved on 8 August 1989, and the first HH-60J entered USCG ...
Many of the helicopters made their way to the civilian market and museums. Under the aircraft designation system used by the U.S. Navy pre-1962, Navy and U.S. Marine Corps versions were originally designated as the HTK, HOK or HUK, for their use as training, observation or utility aircraft, respectively. The Air Force Version was the H-43A ...
The flight controls are directly linked to the swashplate of the helicopter so there are no hydraulic systems in the 269. There are generally two sets of controls, although this was optional on the civil 269A. For three-seat aircraft, the middle collective control stick is removable and a seat cushion can be put in its place for the third ...
