Embodiment 1

[0021] This embodiment provides a method for predicting the landing point of rocket sub-stage wreckage, which can accurately predict the landing point of the rocket sub-stage wreckage after separation, so as to recover the sub-stage wreckage and perform safety control on the area near the landing point

[0022] In practical applications, the method for predicting the landing point of rocket sub-stage wreckage can be implemented by computer programs, such as application software, etc.; or, the method can also be implemented as a medium storing relevant computer programs, such as U disk, cloud disk, etc.; Alternatively, the method may also be implemented by an entity device integrated or installed with a relevant computer program, such as a chip, a mobile smart device, and the like.

[0023] figure 1 It is a flow chart of the method for predicting the landing point of rocket sub-stage wreckage provided in Embodiment 1 of the present application. Such as figure 1 As shown, the ...

Embodiment 2

[0033] This embodiment is based on the above embodiments, and provides a specific implementation of a method for predicting the landing point of rocket sub-stage wreckage.

[0034] figure 2 It is a flow chart of the method for predicting the landing point of rocket sub-stage wreckage provided in Embodiment 2 of the present application. Such as figure 2 As shown, the method for predicting the drop point of rocket sub-stage wreckage provided by this embodiment includes:

[0035] Step 201, establishing a child wreckage rigid body motion model.

[0036] The force on the rocket sub-stage wreckage during flight includes aerodynamic force, earth’s gravitational force and additional force, and the torque includes aerodynamic moment and additional moment. Since the rocket sub-stage wreckage will roll during flight, in order to avoid matrix singularity in the calculation, Quaternions are used to calculate the attitude angle. The rigid body motion model of the sub-level wreckage pr...

Abstract

The embodiment of the invention provides a rocket sub-level wreckage falling point prediction method and device and a storage medium, and the method comprises the steps of obtaining a separation parameter of a rocket sub-level wreckage during separation and an environment deviation parameter affecting the movement track of the sub-level wreckage; and determining a landing point range of the sub-level remains according to the separation parameters, the environment deviation parameters and a preset sub-level remains rigid body motion model. According to the rocket sub-level wreckage falling point prediction method and device and the storage medium, the landing position of the rocket sub-level wreckage can be predicted more accurately, and the landing range is narrowed.

Description

technical field [0001] The present application relates to the recovery technology of wreckage after rocket launch, and in particular to a method, device and storage medium for predicting the landing point of rocket sub-stage wreckage. Background technique [0002] In order to improve the carrying capacity of the multi-stage solid launch vehicle, after the completion of the work of each stage of the engine, useless structures such as the engine casing are thrown away to form the sub-stage wreckage of the rocket. During the flight of the rocket, the landing area of ​​the wreckage of the sub-stage cannot be a densely populated area, and the landing area needs to be safely controlled. Therefore, it is necessary to predict the landing point of the wreckage of the sub-stage of the rocket and predict its possible landing area in advance , and carry out security control. [0003] The rocket is steerable during flight, allowing trajectory adjustment and tracking. However, after the...
