Abstract
The invention relates to the technical field of rockets, in particular to a radial thrust collecting mechanism and a thrust vector measuring device and method. The radial thrust acquisition mechanism comprises a first fixed frame, a first movable frame, a pulley and a radial tension and pressure sensor; the first movable frame is arranged in the mounting hole of the first fixed frame and forms an annular interval; a preset cylinder area is formed in the annular first movable frame, at least three pulleys are connected with the first movable frame and arranged around the preset cylinder area, and the sliding direction is the axial direction so as to clamp a to-be-detected component in the preset cylinder area; the radial tension and pressure sensor can strain in the radial direction and is connected with the first fixed frame and the first movable frame, so that the first movable frame can move in the radial direction. The thrust vector measuring device comprises the radial thrust acquisition mechanism. The thrust vector measurement adopts the thrust vector measurement device. According to the radial thrust acquisition mechanism, the thrust vector measurement device and the thrust vector measurement method, independent measurement of the radial thrust and measurement of the combined thrust direction of the engine are realized.
Description
technical field [0001] The present application relates to the field of rocket technology, and in particular, to a radial thrust acquisition mechanism, a thrust vector measurement device and a method. Background technique [0002] In the field of thrust measurement of liquid rocket engines, to achieve vector measurement of engine thrust (that is, to measure thrust magnitude and thrust direction at the same time), it is often necessary to use a six-component force sensor. The six-component force sensor can realize the measurement of single-point and multi-directional force, and the vector measurement effect can be achieved by using multiple sensors in combination, but the six-component force sensor needs to be customized, has poor versatility, and is easily damaged. [0003] When using the pull pressure sensor for thrust measurement, only axial measurement can be achieved at present, but radial measurement cannot be achieved, and the direction information of the combined thrus...
