Embodiment Construction

[0047] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0048] Such as figure 1 Shown is the specific flow chart of this method realization. First of all, it is necessary to mathematically model the whole process of airdrops / paratroopers from the initial exit of the cabin to the final stable landing.

[0049] Step 1. Carry out mathematical modeling for the whole process of the airdrop / paratrooper from getting out of the cabin to the final stable landing, including three models: the full three-dimensional dynamic model of the parachute, the nonlinear spring damping model of the connecting rope, and the Full 3D dynamic model;

[0050] In the nonlinear spring damping model of the connecting rope, a full three-dimensional hoisting point action judging algorithm is adopted for multi-hanging points, and all multi-hanging point actions under different three-dimensional postures are automatically judged accor...

Abstract

The present invention discloses a pre-evaluation method for large-scale airdrop and airborne landing points. The method comprises the steps of establishing dynamic models for airborne materials and skydivers after airdrop and airborne deplaning; simulating motion tracks of the airborne materials and the skydivers after deplaning; obtaining all parameters in an working process of an airdrop and airborne system; then calculating landing point coordinates of the airborne materials and the skydivers; and drawing a landing point scatter diagram. In this way, the overall working process of the airdrop and airborne system can be analyzed and studied in a directly visible mode. Therefore, the pre-evaluation method can help commanders to scientifically draw up an airdrop and airborne scheme for air dropping of materials in earthquake relief work or for maneuvers. The method adopts a Monte Carlo method to perform simulation and statistics on impacts of these different cases, so that calculation is closer to reality situations. According to the method provided by the present invention, the landing dispersion degree of airborne troops and airborne materials can be predicted, so that the large-scale airdrop landing dispersion area can reduced, the aggregation time can be shortened, and the airborne consumption can be decreased. Therefore, the method plays a crucial role in improving the mobility and overall support capability of the airborne troops, and reducing the consumption of the airborne materials.

Description

technical field [0001] The invention relates to the field of airdrop technology, in particular to a large-scale airdrop landing point pre-evaluation method. Background technique [0002] With the rapid development of applied computer technology, computer numerical calculation and computer simulation technology are becoming more and more mature. In the early 1990s, related technologies in our country began to develop vigorously, but the calculation and simulation research for airborne airdrops started relatively late. Software for airdrop system design and performance calculations is particularly lacking. By establishing the dynamic model of the airdrop and parachutist after airdrop and airdrop, simulating the trajectory of the airdrop and parachutist after leaving the plane, and using computer simulation to obtain various parameters of the airborne airdrop system's working process, the landing can be calculated Point coordinates, draw a scatter map of landing points, intuit...
