A powered lift aircraft takes off and lands vertically under engine power but uses a fixed wing for horizontal flight. Like helicopters , these aircraft do not need a long runway to take off and land, but they have a speed and performance similar to standard fixed-wing aircraft in combat or other situations.
The Osprey is a multi-mission aircraft with both a vertical takeoff and landing (VTOL) and short takeoff and landing capability . It is designed to perform missions like a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft. The FAA classifies the Osprey as a model of powered lift aircraft. [15]
Elevators' effect on pitch Elevator and pitch trim tab of a light aircraft. Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer.
The charts show the added lift benefit produced by ground effect. [3] For fan and jet-powered vertical take-off and landing (VTOL) aircraft, ground effect when hovering can cause suckdown and fountain lift on the airframe and loss in hovering thrust if the engine sucks in its own exhaust gas, which is known as hot gas ingestion (HGI).

Lift is proportional to the density of the air and approximately proportional to the square of the flow speed. Lift also depends on the size of the wing, being generally proportional to the wing's area projected in the lift direction. In calculations it is convenient to quantify lift in terms of a lift coefficient based on these factors.
Archer is developing electric vertical takeoff and landing aircraft (eVTOL) that promise efficiency as well as a quieter and more eco-friendly alternative for urban travel. In 2024, Archer ...
The plane is to be sold as an experimental kit aircraft that requires only a private pilot license. [15] In October 2020 with a $60 million investment in Joby Aviation, a business building an electric vertical takeoff and landing (eVTOL) aircraft intended to provide air cab service, Delta joined the list of airlines funding EV technology startups.
Last December, self-described serial entrepreneur Matt Chasen announced the launch of LIFT Aircraft, a company that recently released an electric, vertical-takeoff machine that doesn't require a ...
