A large and medium-sized fixed-wing unmanned aerial vehicle airdrop system and airdrop control method

Abstract

The invention discloses a large and medium-sized fixed-wing unmanned aerial vehicle airdrop system. On the basis of the original unmanned aerial vehicle, the invention adds a ground proximity warning system and a mission computer. The system can collect relevant flight data information on the aircraft and use itself The terrain database and the airport runway / obstacle database perform warning calculations to determine whether there is a possible near-ground danger for the aircraft. By reminding or warning the crew in advance, it is possible to avoid the situation where the drone cannot be effectively controlled in bad weather such as rain and fog. Or the accident that the plane hits the ground, hits the mountain or flies into the water when the judgment of the spatial direction is wrong. The invention discloses an airdrop control method for a large and medium-sized fixed-wing unmanned aerial vehicle. This technology can reduce the flying height of the remodeled unmanned aerial vehicle to 200 meters during airdrop. In turn, the height of the airdrop is greatly reduced and the accuracy of the airdrop is improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle control, and in particular relates to a large and medium-sized fixed-wing unmanned aerial vehicle airdrop system, and also relates to a large and medium-sized fixed-wing unmanned aerial vehicle airdrop control method. Background technique [0002] Airdrop is a very important means of troop delivery and material supply, and plays an indispensable role in modern warfare. Its development has brought about a fundamental change in military logistics, realizing timely, appropriate, and appropriate delivery of equipment, supplies, and military supplies, that is, regional logistics materials in remote mountainous areas, plateau areas, and offshore islands and reefs under complex weather conditions. It can also realize intelligent, fast and accurate delivery, making up for the lack of single means of transportation in the above areas and being greatly affected by seasonal climate; for manne...

Problems solved by technology

Its development has brought about a fundamental change in military logistics, realizing timely, appropriate, and appropriate delivery of equipment, supplies, and military supplies, that is, regional logistics materials in remote mountainous areas, plateau areas, and offshore islands and reefs under complex weather conditions. It can also realize intelligent, fast and accurate delivery, making up for the lack of single means of transportation in the above areas and being greatly affected by seasonal climate; for manned aircraft, bad weather such as rain, fog and strong wind will reduce visibility, affect the pilot's sight, and increase the difficulty of pilots controlling the aircraft , will double the probability of flight accidents; UAVs will also deviate from the flight route under the influence of bad weather, cannot complete the delivery task accurately, and the aircraft will also hit the ground, mountains, water or fly into residential areas accidents, etc.

[0003] The low-altitude flight height of drones affects the falling time of goods after airdrops. This indicator will directly affect the accuracy of airdrops in complex environments
