VTOL X-Plane hypothetical concepts. T ilt-wing aircraft, as well as other vertical takeoff and landing (VTOL) aircraft, offer multiple benefits when used in unmanned aerial vehicle (UAV) applications. Compared to widely used multicopter systems, convertible VTOL aircraft feature a longer flight range, higher payload, and higher airspeed at the expense of mechanical complexity and the need for sophisticated flight by:

    Firehawk — a VTOL multi-role fighter jet that appears in Command & Conquer 3. The craft is a two-seat, forward-swept wing design with rearwards-swept winglets and canards. It can be outfitted with special boosters that enable it to go sub-orbital, allowing it to bypass anti-aircraft fire. The Harrier, informally referred to as the Harrier Jump Jet, is a family of jet-powered attack aircraft capable of vertical/short takeoff and landing operations (V/STOL). Named after a bird of prey, it was originally developed by British manufacturer Hawker Siddeley in the s. The Harrier emerged as the only truly successful V/STOL design of the many attempted during that cturer: Hawker Siddeley, British Aerospace / .

The book starts with wartime German projects such as the Focke Wulf Treibflugel, Heinkel Wespe, and VTO rocket fighters/5(6).Vertipedia is a comprehensive source of information on vertical flight.

Vertipedia provides high-quality information on current and historical aircraft, as well as notable milestones in the history of vertical flight and biographical information on the people who made them happen.

Some VTOL aircraft can operate in other modes as well, such as CTOL(conventional take-off and landing), STOL (short take-off and landing), and/or STOVL(short take-off and vertical landing). Others, such as some helicopters, can only operate by VTOL, due to the aircraft lacking landing gear that can handle horizontal motion.

VTOL is a subset of.
