Abstract
The purpose of this paper is to introduce the problem of propulsion induced ground effects. These ground effects are usually associated with V/STOL aircraft which utilize medium or high disc loading propulsion devices (lift jets, fans, and augmenters) for vertical flight. The exhaust flow from these propulsion systems can affect the ground environment, the aircraft and the propulsion device itself. These interactions (ground effects) can have a severe impact on the vertical takeoff and landing performance of V/STOL aircraft.
