Background Art
[0002] Modern torpedoes hold a crucial position in naval warfare. They attack the target ship's hull below the waterline from underwater, posing a serious threat to its survival. To strengthen defenses against torpedo attacks, many large ships (such as aircraft carriers and large missile destroyers) have one or more layers of thickened armor on their sides, significantly enhancing their torpedo defenses. Correspondingly, torpedo technology has also seen new developments; high speeds and large warheads increase the kinetic energy of a torpedo attack. However, the kinetic energy of a torpedo in water depends not only on its weight and speed, but also on its displacement and water resistance. Therefore, new torpedo technologies are needed to improve its combat effectiveness. Summary of the Invention

[0006] The invention discloses a multi-stage torpedo capable of flying in the air. The first stage comprises a control device (9) for underwater navigation of the torpedo, a power device (10) for underwater navigation, a fin (11) for stabilizing attitude of underwater navigation, a control device (12) for controlling a rudder for underwater navigation, an underwater navigation control rudder (13), a transmission mechanism (14) for outputting underwater navigation power, and a coaxial counter-rotating propeller (15) for driving the torpedo to sail in the water. According to the requirements of combat missions, a battery can be used to power a motor driving the propeller, or a thermal device can be used as power to drive the coaxial counter-rotating propeller (15) through the transmission mechanism (14) for outputting underwater navigation power of the torpedo. The coaxial counter-rotating propeller (15) is used for underwater navigation of the torpedo, and the counter-torques of the coaxial counter-rotating propeller (15) cancel each other. The coaxial counter-rotating propeller (15) has two groups, each group has four blades, and a magnetic coupling method is adopted to isolate the coaxial counter-rotating propeller (15) and the transmission mechanism (14), thereby ensuring that the transmission mechanism (14) has good seawater sealing performance. The second, third and subsequent stages all use solid-fuel rocket engines, which are identical in structure and can be easily cascaded to increase the range. They are low-cost, easy to store and maintain. The torpedo head consists of a full radar active seeker (1), a torpedo flight control system and inertial navigation system equipment (2), a cross-shaped fully movable control wing for torpedo flight (3) and an armor-piercing warhead with explosive charge (4). The second, third and subsequent stages all have their own power supply, engine ignition control mechanism and a cable for signal transmission with the next stage. The cable transmits information from the control system equipment (9) for the first stage underwater navigation of the torpedo to the second stage, ensuring that when the first stage power unit finishes working and the torpedo presents a head-up tilted posture, the second stage power unit ignites, the first stage is separated, and the torpedo flies out of the water. On the bottom plate of the previous stage, there is a sealed wall socket (30) for the cable, which is connected to the plug of the next stage. The sealed wall socket (30) is equipped with a pin and forms a sealed structure with the socket shell using sealing material. The socket shell has a mounting hole.

The above two grounding measures can ensure that the electrostatic potential between the front and rear stage shells is the same; the front and rear stage shells (16, 28) are made of aluminum alloy, and after chemical oxidation and conductive surface treatment, a surface with low contact resistance is formed, which is conducive to the grounding of the sheet-shaped ground spring (29); the material used for the shell skin is determined according to the functional requirements of each stage. When the first stage sails at a depth of 20m underwater, glass fiber composite material is selected. The shell skin is made to be able to withstand 2 atmospheres of pressure; the second stage flies in the air with a maximum speed of the speed of sound, and aerodynamic heating is not serious, so glass fiber composite materials are still used to make the shell skin; the third stage and the warhead fly in the air at supersonic speed, which will generate aerodynamic heating, so carbon fiber composite materials with low specific gravity, high strength and high temperature resistance are used to make the skin; high temperature resistant alumina ceramics are used to make the antenna cover, which can ensure the normal operation of the full radar active seeker (1) during supersonic flight; the radar of the full radar active seeker (1) works in the 2cm band and adopts single pulse ranging and lateral direction; the antenna's combined beam is used to transmit and receive distance echo signals, and the antenna's pitch The elevation difference beam and the azimuth difference beam are used to receive the pitch and azimuth echo signals of the target, and finally form the ranging and angle tracking control signals of the target through the corresponding sum channel, pitch difference channel and azimuth difference channel, and realize the tracking control of the target through the processing computer of the flight control system, and then realize the tracking of the target by the torpedo through the cross-shaped full-movable control wing of the torpedo flight; the torpedo flight control system and inertial navigation system equipment (2) have three-dimensional inertial sensors, which sense the change information of the torpedo attitude during flight, form the flight control signal through the processing computer of the flight control system, and then realize the flight attitude control of the torpedo through the cross-shaped full-movable control wing of the torpedo flight.
