[0056] According to the demand for underwater autonomous reconnaissance and blasting capabilities in a special field, a split high-energy blasting device applied to micro-unmanned aerial vehicles is proposed. The split high-energy blasting device of this micro-unmanned aerial vehicle weighs no more than 65 kilograms and has an overall length of no more than 1.5 meters. It is required to have underwater autonomous navigation, underwater small target detection, terrain reconnaissance, anti-frogman sonar detection and other detection capabilities, and has a certain blasting disposal capability, which can destroy a 12 mm thick steel shell.

It is only installed when it performs blasting disposal tasks, and the installation requirements are convenient, and the transportation and use safety are high. Under the premise that the performance of this type of product meets the indicators, the overall weight and size of the underwater unmanned vehicle bring great difficulties to the design of high-energy explosive devices.
