Time-Dependent In-Flight Thrust Determination
To examine aircraft and engine operating conditions under which the quasi-steady thrust assumption is valid.
To determine the extent to which time-dependent (nonstationary) force accounting for engine net thrust and propulsion system throttle-dependent terms is required, consistent with existing and developing thrust-minus-drag techniques.
To report time-dependent thrust methodologies and measurement techniques used for flight and ground testing.
To present the results of a data review of state-of-the-art methodology appropriate to the determination of aircraft-installed thrust during quasi-steady and dynamic maneuvers.
To provide guidelines for validating and improving time-dependent thrust determination as appropriate to a specific program.
