针对向太阳高纬发射日冕探测器科学任务,对借金星引力探测器轨道设计进行了研究。用圆锥曲线拼接法给出了地球逃逸轨道参数中的升交点赤径和近地点幅角的解析解,保证了快速设计轨道。分析数组飞往金星的日心过渡轨道发现:首次飞入金星影响球前探测器日心轨道偏心率较大,是保证多次借金星引力提高倾角的关键;当探测器日心轨道偏心率接近零时,借力后轨道倾角不会继续提高。设计了与金星轨道周期相等的三次金星借力轨道,倾角最终达到黄纬20°以上。
In view of the scientific task of launching a coronal detector to the high latitudes of the sun, a study on the orbit design of a gravitational probe by means of Venus was carried out. Using the conic splicing method, the analytic solution of the ascending point and the argument of the ascending point in the escape trajectory parameters of the Earth is given, which ensures the rapid design of the orbit. Analysis of the array to the orbit of Venus transition to the discovery of Venus: the first time into the Venus impact of the ball before the orbital heliocentric orbital eccentricity is to ensure that many times by borrowing Venus gravity to increase the angle of inclination; when the detector orbital heart rate close to Zero, leveraging the orbit inclination will not continue to improve. The three Venus lean orbits, equivalent to the orbital period of Venus, have been designed to eventually reach a dip angle of 20 ° or more.
