XV-2

General information
Type	Stoppable rotor aircraft
National origin	United States
Manufacturer	Sikorsky Aircraft
Status	Canceled
Number built	0

TheSikorsky XV-2, also known by theSikorsky Aircraft model numberS-57, was a planned experimentalstoppable rotor aircraft, designated as aconvertiplane, developed for a joint research program between theUnited States Air Force and theUnited States Army. The program was canceled before construction of the prototype began.

Design and development

[edit]

The XV-2 was developed as part of a joint U.S. Air Force and U.S. Army program intended to explore technologies to develop anaircraft that could take off and land like ahelicopter but fly at faster airspeeds, similar to a conventionalairplane. The XV-2's stoppable-rotor design was intended to allow it to hover and fly at low speed like a conventionalhelicopter. It utilized a single-bladesingle-rotor design; a counterweight provided stability to the rotor system,^[1] while a tip-jet arrangement powered the rotor, which retracted into the upper fuselage when stopped, the XV-2 then flying like a conventional aircraft ondelta wings.^[2] A single jet engine was provided for forward flight, and was to be equipped withthrust vectoring for steering in hover and for anti-torque control in lieu of a tail rotor.^[3]

The XV-2 prototype was assigned the serial number 53-4403, but the project was cancelled before construction could begin.^[4]
