Embodiment Construction

[0023] Below, the present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 Shown is a schematic diagram of the results of the test device of the present invention. A supercavitation test device, comprising a hull 1, a power system 2, a supercavitation hydrofoil 3, a supercavitation test model 4, a test assembly 5, a ventilation system 6, a battery pack 7, a motor 8 and a control system 9; The test assembly 5, ventilation system 6, battery pack 7, motor 8 and control system 9 are all arranged in the inner space of the hull; the hull 1 is composed of a hull 11 and a hatch cover 12. The hull is used to provide space for component installation and partial lift, and the hatch cover is used to block various components to prevent water from entering the interior space during the test.

[0025] Described power system is made up of primary power system 21 and secondary power system 22; Described primary power...

Abstract

The invention belongs to the supercavity test research field and relates to a supercavity test device and a test method. The test device comprises a ship body, a power system, super-cavitation hydrofoils, supercavity test models, a test assembly, a ventilation system, a battery pack, a motor and a control system, wherein the test assembly, the ventilation system, the battery pack, the motor and the control system are arranged in an inner space of the ship body. The ship body is formed by a hull and a cabin cover plate. The power system is formed by a first-stage power system and second-stage power systems. The first-stage power system is arranged at the tail portion of the ship body; and the second-stage power systems are arranged at the tail portions of the supercavity test models respectively. The two sides of the ship body are provided with two supercavity test models respectively, which are connected to the hull through the super-cavitation hydrofoils respectively. The invention also provides a supercavity test method. Through the hull, the super-cavitation hydrofoils and ventilated cavitation drag reduction design, the supercavity test device helps to improve navigation speed, and meets requirements for supercavity test speed and environment.

Description

technical field [0001] The invention belongs to the technical field of supercavitation test, and relates to a supercavitation test device and a test method, which support and drive the supercavitation test. Background technique [0002] Supercavitation refers to the phenomenon that the air bubbles surrounding the surface of the vehicle are formed under the condition of high-speed navigation or artificial ventilation of the vehicle. Supercavitation can realize efficient drag reduction of underwater vehicles, which has attracted widespread attention from researchers at home and abroad. The performance of the traditional power system using propellers as propulsion devices drops sharply at high speeds, so new underwater jet propulsion power systems, such as water ramjet engines, have become the preferred power devices for supercavitating vehicles. It is one of the key technologies in the research of supercavitating aircraft to carry out dynamic supercavitation tests, assess the...
