Problems solved by technology

When the structure enters the water, it will arouse the movement of the surrounding medium; in turn, the fluid medium exerts various reaction forces on the structure, especially during the transient impact of entering the water (millisecond level), the structure will be subject to a huge impact Load, theoretical analysis is quite difficult
[0003] In the existing technology, the patent No. 03105301.7 is the invention patent of the rocket-assisted launching device and its method, which uses the shock wave generated by the explosion of gunpowder to generate the thrust required for launching the rocket, but the repeatability of this launching method is poor and there is a certain degree of safety. Hidden danger

Description

technical field [0001] The invention relates to the field of high-speed water-entry launching experiment devices, in particular to a variable-angle and variable-speed water-entry launching device for structures. Background technique [0002] The 21st century is the century of the ocean. The development, utilization and protection of the ocean has become an important subject of scientific research in various countries. In the field of ships and oceans, the problem of water entry of structures has an extensive and realistic engineering research background. The launching of underwater weapons, attacking ships, landing of seaplanes, torpedoes entering water, and launching underwater vehicles are all physical phenomena that belong to water entry. category. "Water entry" generally refers to the process in which an object hits the water surface at a certain speed or enters the water from the air. According to the speed of the water entry structure, the water entry can be divided ...
