The X-Wing is a hybrid helicopter-airplane configuration designed to combine the low speed and hover capabilities of a helicopter with the high speed and altitude capabilities of a jet fighter.

The concept uses helicopter mode in low speed environments and for landing and take-off. It transitions into airplane mode by stopping the oversized helicopter main rotor to use as the airplane wing.

Examples of this configuration:

  • Sikorsky S-72 RSRA (NASA Rotor Systems Research Aircraft)
