Abstract

Abstract

When researching on the influence of the inlet and jet exhaust plume of the embedded propulsion system on the aerodynamic characteristics of a blended wing/body aircraft, a calibration method of thrust and drag for the integral inlet and jet simulation test is developed. The embedded ejector integrated with the aircraft model is employed to simulate the inlet and jet effects simultaneously. The total value of the aerodynamic load on the aircraft model and the thrust of the working ejector are measured by the balance. With the TPS calibration tank, the thrust and drag of the propulsion system can be calibrated, the decoupling of the aerodynamic load on the aircraft model with the thrust and drag of the propulsion system can be efficaciously realized, and the reliability data of inlet and jet effects can be obtained. The thrust/drag calibration method is verified by the inlet and jet simultaneously testing with black-embedded inlets of a blended wing/body aircraft.
