Accurate air-drop system

Abstract

An accurate air-drop system comprises a task planning module, a weather information module, a parafoil module, an integrated navigation module, a flight control module, an attitude control module, a cargo platform module, a landing unlocking module, a remote control and remote measurement module and a ground station module. And the task planning module plans a flight path point for the descendingprocess of the parachute by utilizing the task information and the information provided by the weather information module, and calculates a reasonable air-drop release area. The integrated navigationmodule adopts GNSS / INS / laser radar integrated navigation to obtain system position and attitude information; the flight control module controls the rear edges of the two sides of the parafoil throughthe attitude control module, the parafoil flies autonomously according to a preset track in the whole process, high-precision sparrow landing is achieved, and the remote control telemetering module completes telemetering communication and control over the precise air-drop system in the whole process. The precise air-drop system can realize full-height drop and precise landing under three unconditions (no ground guidance, no ground control and no meteorological data).

Description

technical field [0001] The invention relates to a precise airdrop system, which is suitable for the research and realization of engineering application technology for accurately delivering materials or personnel to designated places. Background technique [0002] Traditional airdrops use an uncontrolled circular umbrella system, which cannot be manipulated to change its aerodynamic shape after delivery. Scattered due to the influence of the wind field cloth The area is very large, which leads to low landing accuracy of airdrops, large spread of landing points for airdrops, and traditional airdrops without a landing function. The landing speed is high, and it is easy to damage the airdropped materials. [0003] Tradition The disadvantages of the airdrop system mainly include: (1) The system has no control capability; (2) The airdrop mission is not planned, and the landing accuracy in harsh environments is poor; (2) There is no full-range autonomous flight capability. (3) ...

[0002] Traditional airdrops use an uncontrolled circular umbrella system, which cannot be manipulated to change its aerodynamic shape after delivery

Scattered due to the influence of the wind field cloth The area is very large, which leads to low landing accuracy of airdrops, large spread of landing points for airdrops, and traditional airdrops without the landing function. The landing speed is high, and it is easy to damage the airdrops.

[0003] Tradition The disadvantages of the airdrop system mainly include: (1) The system has no control capability; (2) The airdrop mission is not planned, and the landing accuracy in harsh environments is poor; (2) There is no full-range autonomous flight capability

(3) No bird drop function, airdrop materials are easily damaged
