- The decrease in orbital altitude of an artificial satellite as a result of conditions such as atmospheric drag. 能量消减人造卫星由于大气阻力等的作用结果,在轨道高度上能量消减
- Eventually atmospheric drag removes them from orbit by lowering their altitudes until they burn up on reentry into the dense lower atmosphere. 最终空气阻力会使它们高度降低、移出轨道,在重返地表的过程中,被浓密的低层大气燃烧殆尽。
- Since such a lowly satellite would suffer from atmospheric drag, it would need its own propulsion system and a decent supply of fuel. 如此低空飞行的卫星会受到大气层的拖赘,本身需要推进系统和足够的燃料。
- The shape and perigee of artificial satellite orbits shall continually variate due to caused by the atmospherical drag and the earth gravity. 人造地球卫星的轨道由于大气阻力和地球引力场等因素的摄动,其形状和近地点位置将不断改变。
- The result is the five metre long aerodynamic satellite equipped with low power ion thrusters to compensate for atmospheric drag. 其结果是,5米长的空气动力卫星配备了低功耗的离子推进器,以补偿大气阻力。
- The meeting is gone on in very friendly atmosphere. 会议在非常友好的气氛中进行。
- To make maximum use of the applied thrust, the perigee distance was chosen at a point where the atmospheric drag was negligible and this distance was held constant throughout the escape maneuver. 扑翼飞行器的主要特点是将升力、推进的功能集合于扑翼系统中,由减速齿轮组及四连杆扑翼机构将引擎输出动力转换成所需工作转速及拍扑动作。
