DuPont Aerospace DP-2
Encyclopedia
The DuPont Aerospace DP-2 is a fixed-wing VSTOL transport aircraft that is designed to take off and land like a helicopter
and fly like an airplane. The DP-2 is designed to travel at high subsonic speeds with a greater range than its rotary-wing equivalent, and to allow troops to rappel from the aft cargo ramp. The development of the 53% scale DP-1 aircraft was originally funded as a manned vehicle. During the construction of the test aircraft, ONR program management changed the requirements, and mandated that the vehicle be tested as a UAV. This change added significant cost and time to the project, but in October 2007, the DP-1 autonomous prototype achieved sustained, controlled tethered hovers of 45 seconds at the Gillespie Field test site. The requirement for military helicopters is a 30 second hover.
On June 13 2007, the U.S. House Committee on Science and Technology held a hearing about the fate of the DP-2. http://democrats.science.house.gov/Media/File/Commdocs/hearings/2007/oversight/12jun/hearing_charter.pdf In August 2007, funding was finally cut, after a total of $63 million dollars spent over two decades. The general consensus was that this project was just a pork barrel for the local congressman.
Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by one or more engine-driven rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forwards, backwards, and laterally...
