[0022] In order to solve the difficult problem of simulating the jet flow pipeline and ventilation pipeline, a laboratory simulation forward jet flow experimental mechanism based on motor acceleration was invented, which can be applied to the experimental water tank or free-flying pool experiment. The aircraft model in the water tank can carry the jet pipeline, which is installed on the track as a whole, accelerated by the drive of the motor, and then ejected by inertia to realize free entry into the water. The influ...

Abstract

The invention discloses a laboratory simulation forward jet experiment mechanism based on motor acceleration. The laboratory simulation forward jet experiment mechanism comprises a guide rail, a sliding block, a motor, a motor gear, an electromagnet, an iron sheet, a stopping magnet, a magnet fixing block, a rack, a motor support baffle, a connecting platform, a photoelectric switch, an accelerometer fixing block, a stopping cylinder, a magnet fixing frame, a speed reduction table, a jet nozzle and an accelerometer. Acceleration is carried out through driving of the synchronous motor, inclined ejection can be carried out at a specific speed, and meanwhile the characteristics that ejection is stable and the movement track is stable in the ejection process are achieved. The laboratory simulation forward jet experiment mechanism based on motor acceleration can be widely applied to the field of laboratory simulation equipment.

Description

technical field [0001] The invention relates to the field of laboratory simulation devices, in particular to a laboratory simulation forward jet flow experimental mechanism based on motor acceleration. Background technique [0002] With the development of multiphase flow and cavitation drag reduction technology, for the water entry process of the vehicle, the way of forming ventilating cavitation by jetting forward can significantly reduce the resistance in the water entry process. However, the flow state and resistance law of the air bubble formed by the forward jet flow to assist the vehicle to enter the water are still unclear, and the flow state and resistance law are quite different under different experimental conditions, so further research is needed, especially the flow state and resistance law of the jet flow. Behavior of multiphase flow formed when water surface and gas mix, and load simulation when jet impinges on water surface. And the ejection mechanism that is...
