Product Code:SAE AIR1678
Title:Uncertainty of In-Flight Thrust Determination
Issuing Committee:E-33 In Flight Propulsion Measurement Committee
Scope:This document defines and illustrates the process for determination of uncertainty of turbofan and turbojet engine in-flight thrust and other measured in-flight performance parameters. The reasons for requiring this information, as specified in the E-33 Charter, are:- determination of high confidence aircraft drag; - problem rectification if performance is low; - interpolation of measured thrust and aircraft drag over a range of flight conditions by validation and development of high confidence analytical methods; - establishment of a baseline for future engine modifications.
