项目摘要

Theoretical investigations and simulation through experimental vehicle were conducted for the purpose of realizing a novel orbit transfer vehicle (OTV) in space, based on the tumble orbit transfer principle.OTV transfers a customer satellite into a new orbit by activating its thrusters after capturing the satellite. The OTV under the investigation utilizes a long arm in capturing the customer satellite, or extends its arm after the capture. The thrust is applied in a direction perpendicular to the arm, at one end of the arm. This maneuver causes rotational motion, as well as linear velocity increment, which puts the system into a transition orbit. By separating the satellite at a selected moment on command, the two end masses are put into different orbits by additional velocities of rotation. Out of plane transfer in this manner was confirmed effective by theoretical simulation, in addition to inplane transfer maneuver effects which had been confirmed in earlier investigation.The experimental vehicle makes a free motion on a laboratory floor by levitation by air bearings and thrusters using compressed air. Accelerometers and gyros provide data for attitude/position determination and control. Within the limit of air and electrical umbilicals, the vehicle was confirned to move with very small resistance. After a series of experiments with various configurations, the best configuration was reached by adding compressed air sources for supplying air independently to the thrusters.The present research established element technologies to verify the novel orbit transfer vehicle. The remaining task is to combine control algorithm derived by the theoretical investigation into the experimental vehicle.

为了在太空中实现一种新型的轨道转移飞行器(OTV)，基于滚转轨道转移原理，通过激活卫星捕获卫星后的推进器将其送入新的轨道，进行了理论研究和实验飞行器的仿真。被调查的OTV在捕获客户卫星时使用长臂，或在捕获后伸展手臂。推力在与手臂垂直的方向上施加，在手臂的一端。这种机动会导致旋转运动和线速度增量，从而使系统进入过渡轨道。通过命令在选定的时刻分离卫星，两端的质量通过附加的旋转速度被放入不同的轨道。通过理论仿真证实了这种方式的离面转移是有效的，并利用压缩空气通过空气轴承和推进器在实验室地板上实现了自由运动。加速计和陀螺仪为姿态/位置确定和控制提供数据。在空气和电动脐带的限制下，车辆被确认以非常小的阻力移动。通过一系列不同构型的实验，通过增加压缩气源独立向推进器提供空气，获得了最佳构型，建立了验证新型轨道转移飞行器的单元技术。剩下的任务是将理论研究得出的控制算法结合到实验车中。
