Intercepting and recycling device for high-speed water entry model test

Abstract

The invention discloses an intercepting and recycling device for a high-speed water entry model test, and belongs to the technical field of high-speed water entry tests of underwater vehicles. Comprising an intercepting frame, an intercepting plate frame, an intercepting plate and an intercepting plate angle adjusting device. The intercepting frame is of a frame structure, the intercepting plate frame is a rectangular frame, the two ends of the intercepting plate frame are connected into the intercepting frame through intercepting plate angle adjusting devices and rotating round pipes and can rotate relatively, an intercepting plate is embedded in the intercepting plate frame, two layers of intercepting plates are fixed right in front of the front side end face of the intercepting plate frame in parallel, and a layer of intercepting plate is fixed right behind the rear side end face of the intercepting plate frame in parallel. The two rotating circular pipes are vertically fixed to the middles of the two sides of the intercepting plate frame correspondingly; the angle of the intercepting frame is adjusted by adjusting the screwing-in length of an angle adjusting rod in the intercepting plate angle adjusting device. According to the device, the underwater model can be effectively intercepted and recycled, it is guaranteed that the main body structure of the model is not damaged, and the device is simple in structure and easy to use.

Description

technical field [0001] The invention belongs to the technical field of high-speed water entry tests of underwater vehicles, and in particular relates to an interception and recovery device for high-speed water entry model tests. Background technique [0002] In the future, underwater weapons will develop in the direction of high-speed, long-range, and intelligent. Supercavitation drag reduction is the basis for ultra-high-speed navigation. Supercavitation navigation technology has in turn led to the development of cross-media navigation technology. Cross-medium navigation means that the aircraft can cross the water-air interface and operate under the two media of water and air. It combines the advantages of high-speed aircraft, good underwater concealment, and strong explosion power, thus enabling off-zone launch and low-altitude sea-skimming flight Combined with the ability to repeatedly enter and exit water penetration and underwater attacks, it is an important weapon type...

AI Technical Summary

Problems solved by technology

[0004] If the interception device uses one or two layers of thicker interception plates, although the model can also be decelerated and intercepted, when the model hits the interception plate, the instantaneous impact on the model will be relatively large, which will easily cause damage to the model structure and internal test equipment. Exceeding the range will lead to damage to the internal equipment. At the same time, because the intercepting plate is too thick, the model may not be able to penetrate, so that the model cannot stay on the intercepting plate, and
