摘要： An improved system (11), apparatus and method for estimating thrust from an engine (10), and more specifically, a system (11) for estimating thrust from strain gauge and accelerometer measurements. At least one strain gauge (13) is mounted on an engine (10) mount (44) to measure strain to estimate a constant velocity or steady-state portion of thrust. At least one accelerometer (15) is mounted on the vehicle (50) to measure acceleration to estimate a transient portion of thrust. Steady-state thrust estimation and transient thrust estimation are combined to estimate thrust from the engine (10). An algorithm (23) provides steps for estimating thrust from strain gauge and accelerometer measurements.
