powered lift

Powered lift aircraft are a category of aircraft that can change the direction of their propulsion system's thrust during flight. This capability allows them to take off and land vertically, hover, and fly in any direction. This is achieved through the close integration of the airframe and propulsion system, where the exhaust flow influences the aircraft's aerodynamics.

Examples of powered-lift aircraft include vectored-thrust jets, like the Harrier, where rotating nozzles direct thrust for vertical takeoff and horizontal flight. Another type is the externally blown wing system, where engine exhaust is directed over the wing's surface to generate lift. Helicopters are also a prominent example of powered-lift aircraft, utilizing rotors for vertical flight capabilities. This technology overcomes the need for large runways, offering more flexible point-to-point transportation.12
