Novel multi-vehicle series water entry light-gas gun launching experimental device

Abstract

The invention discloses a novel multi-vehicle series water entry light-gas gun launching experimental device. The device comprises a tripod; a motor and a light-gas gun launching device are fixed ontothe upper surface of a tripod pan-tilt holder; the light-gas gun launching device is provided with a plurality of light-gas gun tubes and a rotating shaft; the output shaft of the motor is connectedwith the rotating shaft; one end of each light-gas gun tube, which is adjacent to the motor, is fixedly provided with a compressed gas cylinder; a vehicle is arranged in one end of each light-gas guntube adjacent to the motor; one end of each light-gas gun tube, which is far away from the motor, is provided with a front-end support; a level is fixed on the tripod; and the light-gas gun tubes areprovided with speed measuring devices respectively. According to the novel multi-vehicle series water entry light-gas gun launching experimental device of the invention, the light-gas guns are adoptedto launch vehicles; the light-gas guns are arranged on the tripod; the inclination angle of the light-gas guns is so accurate that the inclination angle can reach a 0.1 degree-level; by means of a servo motor, the plurality of vehicles can densely enter water at the same position, and can enter water synchronously in a parallel manner at a certain initial speed, and namely, the series water entryand parallel water entry of the vehicles can be realized.

Description

technical field [0001] The invention relates to a water entry test device, in particular to a new type of multi-vehicle series entry light gas cannon launch test device. Background technique [0002] The water entry methods of the vehicle body model mainly include vertical and inclined water entry. The water entry problems correspond to the water entry problems in actual engineering, such as air-launched torpedoes, high-velocity projectiles, and depth charges. It will be subjected to a much higher slamming load than the free fall into the water instantly, and its water entry process is more complicated. In addition, in the military field, the concept of saturation strike has led to the technical path of intensive water entry of multiple vehicles. The mutual influence of various vehicles during the water entry process makes the phenomenon more complicated, and requires a large number of related experiments in the early stage for demonstration. [0003] Usually, the oblique w...

AI Technical Summary

Problems solved by technology

The existing experimental devices mainly study the vertical or oblique water entry characteristics of a single vehicle model, and there are few experimental studies on the oblique water entry problem of multi-body intensive launch, and the control of the inclination angle is relatively rough
