木卫停泊轨道间低耗能小推力转移轨道设计方法研究

对木卫停泊轨道间的低耗能小推力转移轨道设计方法进行了研究,提出基于"类halo轨道截面"法的低耗能转移轨道参数化方法和基于配点法的多体Lambert问题求解算法,并利用全局优化算法得出了燃耗最少的初步优化结果;利用多体同伦法和固定近心点高度的多圈转移控制律得到了各段小推力转移轨道的有效设计结果.所提方法同样适用于其他天体间的转移轨道设计,为多体环境下低耗能小推力转移轨道提出了新的设计思路和方法.

DESIGN METHODS FOR LOW-ENERGY LOW-THRUST TRANSFER ORBIT BETWEEN PARKING ORBITS AROUND JOVIAN MOONS

propose a novel method for low-energy low-thrust transfer orbit between parking orbits around Jovian moons. Using a "halo-like section", the manifold is simply parameterized and patched by the multibody Lambert algorithm based on collocation method. Then by using the global optimization algorithm, a preliminary optimization result is obtained with minimal fuel consumption. The transfer orbits with lowthrust propulsion are optimized and designed by the homotopic method with multi-body environment and the multi-circle transfer orbit design method with fixed perigee height. The proposed method may be applied to transferring orbit design between other celestial bodies. In summary, we have proposed new design ideas and methods for low-energy low-thrust transfer orbit with multi-body environment.
