Abstract

The invention discloses a regular dodecahedron multifunctional deployable target. The invention adopts an inflatable tube skeleton to be inflated and deployed as the buoyancy and support structure of the target, and a flexible deployable skin is spatially deployed to form a spatial regular dodecahedron target. The skin and the skeleton adopt a split design, that is, the flexible deployable skin is replaced according to the needs of different weapon training plans to achieve a target that meets the search, sighting and locking requirements of different strike functions. The inner cavity of the regular dodecahedron multifunctional deployable target is provided with a flexible deployable 30-face radar reflector, and the inflation volume requirement of the internal inflatable tube skeleton is small, so that a large aerial target can be more quickly deployed and formed, which is more convenient and more efficient than traditional targets. The device adopts a regular pentagonal structure with reasonable force, so that the strength of the entire target is maximized and more stable.

Description

Technical Field

[0001] The invention relates to the field of target technology, in particular to a regular dodecahedron multifunctional deployable target. Background Art

[0002] Targets provide maritime targets for naval artillery, missile live-fire shooting or simulation training, and are important maritime equipment for maritime target shooting training and exercises, as well as for testing and evaluating the strike effect. Therefore, the development, product iteration and deployment of targets are of great significance to the development of naval weapon equipment technology and the improvement of combat capabilities. Traditional targets generally use abandoned ships, requisitioned civilian fishing boats and special steel-structured target ships, which are costly, slow to deploy at sea, slow to recover, difficult to tow, pollute the ocean, and cannot be deployed on a large scale. The existing inflatable ball targets are simple and fast to deploy, but once they are damaged or scratched by external forces, the internal air pressure of the entire inflatable ball target is insufficient, and the inflatable ball target immediately fails and must be re-deployed, wasting personnel, time, financial resources, and seriously affecting the progress of training or exercise subjects.
