Description

Submarine multi-energy source cross energy supply unmanned aerial vehicle launching platform

Technical Field

The invention relates to the field of autonomous marine unmanned aerial vehicle launching, in particular to a device for acquiring a multi-energy-driven marine unmanned aerial vehicle launching platform.

Background

The existing submarine-launched unmanned aerial vehicles and torpedoes are launched by underwater vehicles (such as submarines) carried by people, and due to the fact that the unmanned aerial vehicles are high in cost and small in quantity, the unmanned aerial vehicles which cannot be standby and carried at ocean for a long time are small in quantity, and therefore investigation or attack on enemies at ocean at any time cannot be conducted.

With the continuous progress and development of marine intelligent equipment, the key technology of the deep-sea autonomous underwater vehicle is continuously developed and broken through. The development of deep-sea autonomous underwater vehicles requires the breakthrough of a plurality of technologies, wherein the power energy technology, the navigation positioning technology, the underwater communication technology and the autonomous task control technology are the most critical. The requirement on the aspect of power energy of the autonomous underwater vehicle is higher during deep sea operation, so that the required energy density is high, the push button is good, the maintenance is easy, the cost is low, and even the battery is required to bear the conditions of deep sea water pressure and the like. And therefore batteries are often used as energy carriers for aircraft. In the navigation positioning technology, a mode of combining inertial navigation and log navigation is generally adopted for navigation, and the deep-sea autonomous underwater vehicle cannot float out of water in real time to calibrate the inertial navigation, so that the technology becomes the key of the deep-sea autonomous underwater vehicle. The underwater communication technology is mainly through underwater only underwater sound conduction, so that the underwater communication technology is limited in all aspects and has to be greatly developed into a more efficient conduction technology. The autonomous task control technology is not only a key technology of a deep-sea autonomous underwater vehicle, but also a core technology, and comprises the steps of operation task management, intelligent planning, autonomous state inspection and autonomous fault processing, autonomous obstacle avoidance and autonomous navigation, and the autonomy of the vehicle is realized. Many countries today already own autonomous underwater vehicles that are developed autonomously and are used for military operations or scientific research. Such as REMUS6000 in the united states, BLUEFIN-21 in the united states, HUGIN in norway, the seeker in canada, and so forth.

Most autonomous underwater vehicles have limited time to perform tasks in open and deep seas, and their size must be continually expanded in exchange for greater battery capacity in order to increase endurance. Such as REMUS6000 in the united states, the main parameters of which are designed to measure sea water properties such as conductivity, temperature, chemical composition and map the sea floor by sounding, sonar side scan, magnetism, gravimetry and photography, are 71cm diameter, 3.96m vehicle length, 865kg vehicle airborne weight, 6000m maximum working depth, 22h endurance, 4.5kn maximum speed. Wherein the endurance time has been as long as 22 hours. Furthermore, bluefin-21 in the United states is a highly modular autonomous underwater unmanned vehicle that can carry a variety of sensors and payloads. One of the characteristics is that the capacity of electricity is big, even can work for a long time under the condition of extreme depth of water to can use for various emergent propagation operations. The main technical parameters are as follows: the diameter of the aircraft is 533mm, the length of the aircraft is 4930mm, the mass in the air is 750kg, and the maximum working depth is 4500m; endurance: the standard payload is 25h at 3 kn; the navigational speed is 4.5kn. And the first maritime god 6000 capable of conducting deep and open sea search and rescue in China carries a plurality of detecting instruments such as USBL (universal serial bus), an airplane black box search sonar array, deep sea sounding side scan sonar, an underwater camera, CTD (China train digital simulator), a deep sea acoustic communications apparatus, front sonar and the like due to task requirements. The relevant parameters are as follows: the maximum working depth is 6000m, the diameter is 880mm, the length is 7.5m, the maximum sailing speed is 5kn, and the maximum cruising ability is 24h. The three aircrafts are different from each other, although the design parameters are different, the design parameters are almost the same, the space of the aircrafts has to be sacrificed to achieve the cruising ability of nearly one day, and larger batteries are installed in the aircrafts.
