Abstract:

A traversing rake system to be used in measuring the in-flight thrust of a turbo-jet powered aircraft is described. A material development investigation was conducted to obtain a rake which would withstand the pressure and temperatures in a jet during afterburning for short periods of time and also be capable of rapidly and accurately responding to pressure and temperature changes as the rake was traversed across the jet. Calibration tests were conducted with the rake installed in the transonic and supersonic wind tunnels. Evaluations of the traversing rake system installed behind different makes of engines at the Naval Air Turbine Test Station indicated the system is capable of satisfactorily measured gross thrust and mass flow in the plane.
