Abstract:
The development of three-component thrust platform used for the thrust measurement of scramjet is described in this paper. The thrust platform is used to measure axial thrust, lift force and pitching moment in the free jet test. The thrust platform mainly consists of the fixed frame, moving frame, elastic linkage, locking mechanism and thrust force calibration system. The thrust platform obtains measurement matrix through five groups of measuring sensors. The relationship among axial thrust, lift force, pitching moment and measurement matrix is obtained through the three-component thrust calibration. Locking or unlocking of the moving frame is realized by the locking mechanism with hydraulic plug pin structure, which protects the thrust platform while the impact occurs. The thrust measuring performance of the platform was verified by the free jet test. The platform can record the force loaded on the scramjet in the supersonic free jet field, and get the thrust gain. The thrust platform can meet the accuracy requirement of each component measurement and provide
