Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] refer to Figure 1 to Figure 9 As shown, the multi-target-oriented gridded parafoil homing method in an embodiment provided by the invention comprises the following steps:

[0046] 1) Estimate the maneuverability of the parafoil system;

[0047] 2) Grid partition the landable area, and use the center of each grid partition as the approximate target point for landing;

[0048]3) Modify the approximate target points in the non-square grid partition of the outer boundary;

[0049] 4) Correct the grid partitions with avoidance points, and then optimize the approximate target points of the corresponding grid partitions;

[0050] 5) Obtain the final control target point according to the deployment position of the parafoil system after leaving the aircraft;

[0051] 6) Manipulate the parafoil to fly to the obtained final control target point until...

Abstract

The invention discloses a gridded parafoil homing method oriented to multiple targets, comprising the following steps: estimating the maneuverability of the parafoil system; performing grid partitions on landable areas, and using the center of each grid partition as The approximate target point for landing; correct the approximate target point in the non-square grid partition on the outer boundary; correct the grid partition with avoidance points, and then optimize the approximate target point of the corresponding grid partition; according to the parafoil system after leaving the aircraft Expand the position to obtain the final control target point; manipulate the parafoil to fly to the obtained final control target point until landing. It is suitable for a large landing area, where the position of the landing point cannot be determined, or is limited by the landing terrain and topography conditions, and needs to avoid some Under special requirements such as the landing position, the parafoil system is used to realize the safe and controllable recovery of spacecraft, drones and other equipment, improving the accuracy and safety of landing.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to a multi-target-oriented gridded parafoil homing method. Background technique [0002] The precise homing control technology of the parafoil system is the key to realize the precise and safe landing of the parafoil system. Accurate homing depends on two aspects: one is precise navigation and positioning, which obtains the three-dimensional position and attitude of the system in the space field in real time; the other is the parafoil flight control strategy, which guides the parafoil system to fly to the target position according to the planned strategy. Finally reach the predetermined target position and land precisely. [0003] In the prior art, there is an integrated navigation method using satellite / inertial navigation, the data positioning is accurate, and the data update rate meets the requirements of the parafoil system. The parafoil flight control strategy can ...
