A Method for Predicting the Optimum Delivery Point of Airdrops

Abstract

The invention discloses a method for predicting the best delivery point of an airdrop. The parachute is regarded as a three-dimensional, 6-degree-of-freedom variable mass body for calculation. The method analyzes the airdrop during the process of opening and stabilizing the parachute according to the actual working procedure of the parachute drop. The motion characteristics of the material, establish a reliable dynamic model of the material airdrop process, simulate the trajectory of the airdrop after it leaves the aircraft, and calculate the parachute trajectory. And based on the known delivery target point, the Monte Carlo method is used to calculate and analyze the best delivery point, delivery time and delivery angle of the airdrop. Through the high-precision dynamic modeling and solving of the parachute airdrop process in the present invention, the air drop point under the specified airdrop condition can be calculated more reliably, so as to accurately grasp the timing of the drop in the process of implementing the parachute drop, and make the materials Landing in the intended landing field provides a theoretical reference.

Description

technical field [0001] The invention relates to the technical field of airdropping materials, in particular to a method for predicting the best drop point of airdrops. Background technique [0002] From the analysis of the level of domestic airborne airdrop technology, my country has basically solved the problem of "lowering" equipment during the "Eleventh Five-Year Plan" period. However, due to the limited research on the working mechanism of the airborne airdrop parachute system, the success rate of airdrops is low. 1. Airdrops spread over a large area and take a long time to assemble, which is still a problem that cannot be solved by airborne and equipment airdrops, especially in complex climate and terrain conditions, or even unusable. In the process of parachute drop of airdrops, it is an important condition to make the materials land in the predetermined landing field by correctly calculating the drop point and accurately grasping the timing of the drop. It's not just ...
