为了研究降落伞对空投水雷空中弹道的影响,运用动量定理和动量矩定理建立了水雷的六自由度空中弹道数学模型,并在一定假设的条件下建立了降落伞作用力的数学模型。然后对空投水雷的空中弹道进行了仿真分析。结果表明:降落伞对空投水雷起到了很好的减速作用,同时降落伞有利于水雷在空中调整姿态从而以较好的角度入水。 In order to study the influence of the parachute on the airdrop trajectory of the airdrop mine, a six degree of freedom air ballistic mathematical model of the mine is established by using the momentum and momentum theorems. Under certain assumptions, a mathematical model of the parachute force is established. Then the airdrop of airdrop mine was simulated. The results show that the parachute has a good deceleration effect on the air-mined mines, and the parachutes help the mines to adjust their attitude in the air so as to enter the water at a good angle.
