Propulsion measurements and thrust methods presented in SAE 1703 and SAE 1703A place a primary focus on the engine reactionary force (thrust) acting to propel an aircraft in the forward direction. In contrast, this document addresses the use of reverse thrust that encompasses ground and in-flight thrust reversing. The engine reactionary force can be used to supplement aircraft ground deceleration and provide rapid descent capability. The discussion will span commercial and military applications for various engine and reverse thrust configurations.
This SAE Aerospace Information Report is intended to provide a comprehensive reference on the application and considerations pertaining to ground and in-flight thrust reversing. In practice reverse thrust is propulsion system specific due to aircraft integration issues. This report offers technical insights across a spectrum of applications.
