Abstract
The invention relates to a propulsion system concept that is a propulsion system that is integrated in the hull of an aerial vehicle (), which propulsion concept comprises at least one differential velocity fan (), which is arranged on a shaft driven by one or more power units (). The propulsion concept is intended to provide short takeoff and landing distances, high flight speed (high subsonic to transsonic) and to be able to provide low IR signature, low radar signature, a small cross section and low air resistance. The propulsion concept is called HPVO (High Performance Optimized Versatile propulsion). The invention is useful both for air vehicles of the type for conventional takeoff and landing, 'CTOL' (Conventional Take Off and Landing), 'Chair' and for vertical takeoff and landing, “V (t) OL” (Vertical (Take) Off and Landing') and the flying wing (blended-body). The concept is applicable to both large and small aircraft, manned as well as unmanned aerial vehicles.
