Lift fan concept encompasses basically V/STOL propulsion system consisting of high bypass ratio jet engine; jet engine thrust is installed in aircraft for conventional flight and this thrust is used as energy source; lift fans are sized for VTOL; studies indicate that low aspect ratio wings suitable for fan installations compare very well with variable-geometry winged aircraft from mission standpoint; vertifan aircraft can achieve V/STOL at nearly cost of STOL only; vertifan aircraft powered by lift fan propulsion systems are equally applicable to high subsonic or supersonic applications.
