Embodiment 1

[0065] In this embodiment, an air-to-ground strike guided aircraft is taken as an example. The altitude of the target point is 1000m, the release height is 5000m, and the release speed is V r =250m / s, drop angle Q 0 is 0 degrees, the off-axis launch angle is 5.3 degrees, the target is located at a position 10000m away from the guidance aircraft horizontally, and the expected fall angle q d = -70 degrees. The flight trajectory scheme of the guided aircraft is as follows: figure 1 As shown, it is divided into a stable section, a middle guidance section and a final guidance section, and the present invention is aimed at the latter two guidance stages.

[0066] The specific implementation steps of the guidance and terminal guidance handover and guidance information processing method with large drop angle constraints are as follows:

[0067] Step 1. The trajectory scheme adopts the three-stage control scheme of the stable section, the middle guidance section, and the final guida...

Abstract

The invention relates to a method for handing over mid-guidance and terminal guidance and guidance information with large fall angle constraints, and belongs to the technical field of guided aircraft. The purpose of the present invention is to propose a processing method for handover and guidance information of mid-guidance and terminal guidance with large fall angle constraints. The required guidance information; as well as the handover strategy of the middle guidance and the terminal guidance, as well as the overload instructions of the middle guidance and the terminal guidance; in order to ensure that the aircraft flies farther in the middle guidance section, forms a large fall angle in the terminal guidance section, and can strike the target precisely.

Description

technical field [0001] The invention relates to a method for handing over mid-guidance and terminal guidance and guidance information with large fall angle constraints, and belongs to the technical field of guided aircraft. Background technique [0002] In order to improve the air-to-ground strike capability of deep-buried and reinforced targets, targets under bridge openings, and targets in buildings, as well as the launch capability of carrier aircraft outside the defense zone, it is urgent to develop guided aircraft with long range, large fall angle, high fall speed, and good maneuverability. Continuously enrich the means of air-to-ground strikes and enhance strike capabilities, especially the ability to precisely strike the enemy's solid and deep-seated targets. [0003] In order to ensure the range, fall angle, and fall speed requirements of the guided aircraft, it is necessary to design a new aerodynamic layout, ballistic scheme, and guidance control strategy. The gui...
