Description

A kind of folding wing cruiser air-dropping canister and delivery method

technical field

The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a folding-wing cruiser air-dropping canister and a delivery method.

Background technique

The folding-wing cruiser is an unmanned aerial vehicle that can be folded and stored on each wing surface. It is usually launched from a ground launch tube, and can also be mounted on platforms such as transport aircraft and large unmanned aerial vehicles for remote delivery. After the folding-wing cruiser is launched from the launch tube or released from the launch platform, each wing surface is unfolded and locked, and normal flight is carried out. It is usually equipped with a reconnaissance pod for long-distance target reconnaissance. When carrying damage loads such as warheads, it can be used. It can carry out real-time suicide attacks on the discovered targets, and can also carry various loads such as jammers, decoys, and magnetic detectors according to mission requirements.

When the folding-wing cruiser is carried on platforms such as transport aircraft and large unmanned aerial vehicles, the wings must be folded and stored before launching. After the launch, the cruiser must be safely separated from the transport platform. After the safe separation, the cruiser must be released. The airfoil constraint completes the locking of the rover's airfoil deployment. In addition, the flight speed of transport aircraft and large UAVs is usually faster than the maximum flight speed that the folding-wing cruiser can adapt to. Therefore, the cruiser needs to be decelerated after being launched from platforms such as transport aircraft and large drones.

Folding-wing cruiser air-dropping canisters are routinely used for folding-wing cruisers storage, service transfer, etc., and are loaded or mounted on transport aircraft and large-scale UAV platforms for folding-wing cruisers during combat. When launching, the folding-wing cruiser air-dropping canister first separates from the carrier aircraft and descends to a safe height relative to the carrier aircraft. Then the folding-wing cruiser is pulled out of the air-dropping canister by a deceleration parachute, and the cruiser is separated from the air-dropping canister. The airfoils of the cruiser are unfolded. After the cruiser is separated from the airdrop release tube, the parachute continues to decelerate the cruiser to a predetermined speed. After the parachute is separated from the cruiser, the cruiser enters normal flight.

The airdrop release tube usually requires a short-term stable flight under unpowered and uncontrolled conditions, can be safely separated from the carrier aircraft, and can reliably separate from the cruiser and open the deceleration parachute. Therefore, it is urgent to develop a folding-wing cruiser air-dropping canister and a delivery method to solve the above problems.
