Long-distance guiding method for paradrop of cargo by transport plane

Abstract

The invention discloses a long-distance guiding method for the paradrop of cargo by a transport plane, which comprises the following steps of: computing a distance difference and a time difference according to an original total flying distance and time and a desired total flying distance and time; firstly regulating the distance at each constant-speed stage to eliminate the time difference, updating a state initial value after regulating the distance at each constant-speed stage; then regulating the time at each constant-speed stage to eliminate the distance difference, and updating a state initial value after regulating the time at each constant-speed stage; ending the steps when achieving an regulating target; and when the time difference or the distance difference required to eliminateis over a critical range and the regulating target cannot be achieved, ending the method. The long-distance guiding method can adapt to a condition that the distance difference and the time difference are in coexistence so that the desired total flying time and the desired total flying distance can be achieved simultaneously.

Description

technical field [0001] The invention belongs to the field of transport aircraft navigation, in particular to a guidance method for air-dropped goods by transport aircraft. Background technique [0002] In order to successfully airdrop cargo, the transport aircraft must: determine the flight speed, time and distance of each flight stage during mission planning; adjust the flight speed, time and distance of each stage according to real-time conditions during online flight. From the entry point of the airdrop area to the starting point of aiming, the transport aircraft has a process of reducing speed and altitude, which is called the deceleration and heightening stage, and the navigation in this stage is called long-distance guidance. During mission planning, a guidance process is generated, called the original plan guidance process, including several constant-speed flight stages and their adjacent deceleration stages; the sum of the flight time of all constant-speed flight sta...
