摘要
为了明确牵引比参数对空投货物运动状态准确性的影响,采用牵引比参数的条件下,将牵引力与实际牵引伞提供的牵引力进行对比,并建立货物牵引空投运动轨迹模型。通过实例计算出两种情况下货物运动状态,根据计算数据拟合出货物运动状态随时间的变化对比曲线,分析了牵引比参数对货物牵引空投运动状态准确性影响程度,为精确空投中确定货物运动准确状态提供了帮助。
For the sake of confirming the influences of the traction ratio on veracity of cargo state during airdrop, here using the traction ratio, comparing the traction and actual circs, and establishing model of the cargo on airdrop. The article uses example to work out the state of locomotion in both of the circs, and simulates contrastive curves to analyze the influences of the traction ratio on veracity of cargo state, theses offer help of confirming the veracity of cargo state during airdrop.
