Quick Summary

An externally blown wing is a type of powered-lift aircraft system where the exhaust from jet engines is directed over the upper surface of the wing. This design integrates the airframe and propulsion system closely, allowing the engine exhaust to influence the wing's aerodynamics.1

Powered-lift aircraft, in general, can alter the direction of their propulsion system's thrust during flight. This category includes various types, such as the vectored jet, externally blown wing, and externally blown flap systems. Lift itself is the upward force acting on an aircraft wing or airfoil, created by a difference in air pressure above and below the wing due to airflow.12
