Design Ideas of Unmanned Underwater Launch Test Facility

To assess underwater launching technology and avoid test risk of underwater launching vehicle effectively, three design ideas of unmanned underwater launch test facilities of anchoring type, pile leg self-lifting type and caisson type are put forward according to the task requirements with reference to the corresponding foreign design ideas. The composition and function, working principle, working process of the system are briefly described. Based on the real marine environment conditions, the three schemes simulate the launch conditions of the real underwater launch platform realistically, adopt the unmanned mode to ensure their safety, and increase the feasibility of the test facility design schemes with reference to the mature technologies about the designs of such as ships, submarines and offshore platforms. The three schemes are compared in terms of technical difficulties, organization and implementation, and fidelity. The analysis results show that from the aspects of marine environment elements, organization and implementation, maintenance and technical implementation difficulty, all three schemes can meet the underwater launch and test needs of the vehicle, among which the anchored launch platform scheme has the most advantages.
