Embodiment Construction
[0028] The present invention will be further elaborated below in conjunction with embodiment.
[0029] A liquid rocket engine swing interference detection system, composed of a support mechanism 1, a drive mechanism 2, a control mechanism 3, and a gap sensor 4, the support mechanism 1 is connected to the engine frame 6, the engine is lifted to suspend the nozzle 7, and the drive mechanism 2 One end is connected to the engine frame 6, and the other end is connected to the engine nozzle 7. Through the length adjustment, the engine nozzle 7 will swing, and the control mechanism 3 converts the required swing angle and orientation of the engine into the drive mechanism 2 through a trigonometric function relationship. Length, and control the drive mechanism 2 to perform in place, the gap sensor 4 is preset at the gap detection part, and the thickness is consistent with the required gap value. When the gap does not meet the requirements, the sensor is triggered by pressure. If it is n...

The invention relates to a liquid rocket engine swing interference detection system, which consists of a supporting mechanism, a driving mechanism, a control mechanism and a gap sensor, wherein the supporting mechanism is connected with an engine frame; an engine is lifted to suspend a nozzle, one end of the driving mechanism is connected to the engine frame, the other end is connected to an engine spray pipe, the engine spray pipe swings through length adjustment, the control mechanism converts a swing angle and a swing direction required by the engine into the length of the driving mechanismthrough utilizing a trigonometric function relation and controls the driving mechanism to execute in place, a gap sensor is preset at a gap detection position, the thickness of the gap sensor is consistent with a required gap value, and the sensor is pressed and triggered when the gap does not meet the requirement. The liquid rocket engine swing interference detection system has the advantages ofbeing simple in structure, convenient to install and high in compatibility, and can comprehensively detect the swing interference condition of the liquid rocket engine.
Description
technical field [0001] The invention relates to a swing interference detection system, in particular to a liquid rocket motor swing interference detection system. Background technique [0002] Liquid rocket engine swing interference detection is an important part of engine function detection. The purpose is to detect possible interference and small clearance problems that may occur during engine operation in advance. The accuracy and comprehensiveness of detection directly affect the working safety of the engine. The existing detection method is to manually pull the nozzle or frame, so that the nozzle swings relative to the frame to a specified angle and orientation, and then detect the gap between the components of the relevant parts. The angle and orientation are determined by measuring the engine nozzle and the machine. The distance between two fixed points on the frame is guaranteed, and the distance is calculated by the trigonometric function relationship between the tw...
