摘要:
提出了一种有大气地外行星悬飞探测方式,该探测方式是利用被探测天体存在大气的环境特点,实现探测器在被测天体的“飞行”机动,克服目前已有的环绕探测、着陆探测、巡视探测和采样返回探测四类无人深空探测方式受地形、地貌约束无法实现大范围机动就位探测的不足。提出了悬飞探测器的典型任务工作模式设想,建立了悬飞探测器的六自由度动力学模型,并针对太阳系内典型的有大气行星环境(火星和土卫六)特点,给出了悬飞探测器的动力学特性并开展了仿真分析。在此基础上,首次提出了悬飞探测器的可行性约束系数,为悬飞探测器在深空探测的可行性研究提供了理论依据。

Abstract:
At present, the large-scalemaneuver capability of space probes in orbiting exploration, landing exploration, exploration with rovers and sampling and return back to Earth, is greatly constrained by landform features and topography conditions. The Suspension exploration is a newly developed method for exploration mission on the planets with atmosphere. By "flight" maneuver, the probes can take full advantage of planetary atmosphere to collect more scientific exploration data. By Suspension exploration, the maneuver defects of probes can be overcame. In this paper, the concepts of a Suspension probe and its working modes are proposed. A six-degree dynamic model of the probe is set up. Together with the careful study on the environment of the planets with atmosphere in solar system, the dynamic characteristics of the Suspension probe are demonstrated and its exploration targets are listed out. Based on these study results, the evaluation coefficient of feasibility (ECoF) of the Suspension probe is proposed for the first time, thus to lay out theoretical foundation for the feasibility study on the application of Suspension probes in deep space exploration.
