The invention discloses a polar region unmanned
underwater icebreaking
navigation system. After leaving a nuclear
submarine underwater, the
system performs self-propulsion through a
tail rudder wing and a
propeller, and an aircraft opens a fairing. A polar region unmanned
underwater explosion icebreaking aircraft emits high-energy explosives through a main explosive emitting tube and a secondary explosive emitting tube, the high-energy explosives generate huge pressure on an ice layer, the ice layer is damaged, and icebreaking is achieved; a fixed
drill bit of the
drill bit icebreaking aircraft begins to rotate, an extension
drill bit is opened during rotation and is fixed after extension, and the
drill bit generates huge pressure in an ice layer contact area, so that an ice surface is damaged, and icebreaking is realized. The
system is simple in structure, can be used as an ice breaking device, and provides a launching window for a nuclear
submarine to launch missiles in polar regions. According to the polar region unmanned underwater icebreaking aircraft, an underwater ice drilling and
underwater explosion icebreaking combined mode is adopted, the mixed icebreaking mode can be combined and optimized for icebreaking according to different ice layer environments, and in order to enhance the
diameter capacity of an icebreaking window and improve the carrying convenience of the unmanned aircraft, a carrying extension
drill bit is designed, and the extension
drill bit has extension and retraction functions.
