| 摘 要： | 当降落伞在空气中作非定常运动时,空气动量的变化率必须包括在降落伞的运动方程中。空气动量的变化率可用表观质量分量描述,这些分量的大小必须通过实验来确定。该文采用旋量的矩阵记法,推导了降落伞的运动方程,它的表达形式十分简洁,容易求解。

| Abstract: | As a parachute canopy moves unsteadily through the air, its equations of motion must include the rate of change of momentum of the air in which it is immersed. This rate of change of momentum of the air is allowed for by apparent mass components, the magnitudes of which must be determined experimentally. In this paper, by introducing matrix notation of motor, the equations of motion of a parachute are derived, the form of which are very tailored and are readily to be solved. |
