Embodiment Construction
[0033] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] In order to realize the thrust measurement in the ground and high-altitude simulation tests of the 20kN level high-pressure attitude control engine, the invention provides a thrust measurement device for the attitude control engine. The measuring device adopts a one-point load-bearing structure with a single sensor to measure the thrust. The connection between the moving frame and the fixed frame adopts the front and rear mountain-shaped spring sheet structure. It adopts an automatic thrust in-situ calibration system composed of a standard force sensor and an electric cylinder. Afterburner calibration, the transmission path of the calibration force value is consistent with the test conditions. Through in-situ calibration, the influence of propellant supply pipelines, cooling pipelines, and measurement cables on th...
