装备投放是一种部队快速生成战斗力的机动方法.投放过程涉及到气动力学、气固耦合、装备属性等领域知识.通过合理简化,对投放过程的四个阶段分别进行受力分析,在二维情况下建立了对应的微分方程组模型,并给出了相关算例.考虑实际风速、风向等随机参数的影响,在三维情况下建立了带参的微分方程模型,并随机模拟了装备降落点的范围.建立的数学模型对定点降落,及时把握空投最佳时机有积极的指导意义.
Equipment delivery is a kind of maneuvering method that the unit can quickly generate combat effectiveness.During the delivery process involves the knowledge of aerodynamics, gas-solid coupling, equipment properties, etc. By reasonably simplifying, the four phases of the delivery process are respectively analyzed by forces, The corresponding differential equation model is established and the relevant examples are given.According to the influence of the random wind speed and wind direction parameters, a differential equation model with parameters is established in three-dimensional case, The mathematical model established has a positive guiding significance for landing fixed time and grasping the best time for airdrop.
