Multiple high-speed aircraft models McDonnell XV-1 was created by American engineers in 1951 year. As a base, American experts have several models made in Germany, produced before the Second World War, however, the designers did not use the design and principle of operation of aircraft data, which has been improved, allowing the helicopter McDonnell XV-1 was able to accelerate to higher speeds and gained higher functionality, although the actual use of the current model and have not received.
The helicopter McDonnell XV-1 has improved aerodynamic design, which in turn makes it a high-speed aircraft, although with reduced maneuverability qualities. Due to the high speed and sufficiently compact design, the aircraft to be used for a variety of purposes, including as a search-and-rescue vehicle, as a small vehicle, as a patrol and reconnaissance aircraft, and even as an independent fighting unit, able to effectively combat the enemy's manpower and lightly armored vehicles.

His first flight tests of the aircraft McDonnell XV-1 1954 been in the middle of the year, however, the project was not able to fully meet the expectations of aviarazrabotchikov. In this connection, a little later he was presented the second prototype of the aircraft with a higher flight-technical qualities and is more reliable in terms of its operation. Nevertheless, the military leadership of the armed forces of the United States responded with disapproval of the current model, in connection with which all work on the design of the helicopter McDonnell XV-1 were curtailed.
On board the aircraft machine model McDonnell XV-1 can accommodate up to three people, including one pilot and two soldiers, either, if the helicopter intended to be used as a search-and-rescue vehicle, only one additional crew member, who was involved in the rise of the people on board. If necessary, the aircraft could also carry out transportation to 500 kg of payload, however, in this context, as well as in the fighting, the helicopter was not tested due to the closure of the project.
The power plant helicopter McDonnell XV-1 consists of a piston radial aircraft engine brand Continental R-975-19, which is able to develop traction in 525 hp and disperse the aircraft up to speed in 325 km \ h. Maximum the same distance that the aircraft of this model can carry out air travel is 955 kilometers, which is very impressive.
