Micro-thrust measuring device for solid rocket engine

The utility model provides a micro-thrust measuring device for a solid rocket engine. The micro-thrust measuring device comprises a bracket, a thrust sensor and a transition frame, the support and the thrust sensor are connected through a flange plate, the transition frame is located above the thrust sensor, and the transition frame is used for placing a solid rocket engine and is further limited and fixed through the support; it is guaranteed that the solid rocket engine is in a vertical state in the test process, and the axis of the transition frame is parallel to the thrust axis of the solid rocket engine. The device solves the problem of thrust test of the large slenderness ratio micro-thrust solid engine. The test device adopts an inverted test run structure, and is novel in structure, high in integrity and strong in innovativeness. Through test verification, the engine is convenient to assemble, safe, reliable and high in test precision, and the requirement of engine thrust test precision can be met. 本实
