Product Code:SAE AIR6064
Title:REVERSE THRUST
Issuing Committee:E-33 In Flight Propulsion Measurement Committee
Scope: 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.
Rationale: 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.
