Medium-low altitude balloon flight path prediction method

Abstract

The invention belongs to the technical field of balloon flight path planning, and discloses a medium-low altitude balloon flight path prediction method, which comprises the steps of obtaining balloonsystem parameters, and a predetermined task flight height and a landing point of a balloon; carrying out interpolation to obtain environmental parameters of the balloon at any height from the ground to the flight height of the predetermined task; calculating the balance weight of the balloon when the balloon flies on the ground; establishing a thermodynamic equation in the balloon rising process,a kinetic equation, and a kinematic equation; predicting to obtain a flying point of the balloon, a rising track of the balloon from the ground to the starting point of the level flying stage and a motion track of the balloon in the level flying stage. The problem of balloon flight path prediction and planning is solved, the balloon can complete a flight task according to the planning path and height, and high-precision prediction of the flight path of the medium-low altitude balloon is realized.

Description

technical field [0001] The invention belongs to the technical field of balloon track planning, in particular to a method for predicting the flight track of a medium-low altitude balloon. Background technique [0002] At present, there are few domestic researches on the flight trajectory prediction methods of medium and low altitude balloons. The trajectory prediction methods of balloons are mainly based on theoretical research, and there are not many applications. During the whole process of flight simulation, the domestic research mainly focuses on the changes of balloon parameters, altitude and speed. There is no requirement for the mission area, and it is difficult to reach the predetermined target position and altitude. [0003] By carrying optical, microwave and other remote sensing loads and wireless communication loads, the balloon system provides new technical means for application requirements such as air and space early warning, battlefield reconnaissance and surve...

AI Technical Summary

Problems solved by technology

If the flight trajectory is not planned correctly, there will be no trace after the balloon is released, and the altitude and position will not meet the standard, which will directly lead to the failure of the mission
