三角平动点的探测与开发:回顾与展望
Exploration and Development of Triangular Libration Points:Review and Perspective
摘要
Abstract
Triangular libration points,as the dynamical equilibrium points in the circular restricted three-body problem,have attracted significant attention in deep space exploration missions in recent years owing to their unique stability and geometric configuration.In this paper,the research progress of triangular libration points is reviewed,and their future application directions are prospected.Based on the critical mass ratio theory,the linear and nonlinear stability conditions of major celestial systems in the solar system are analyzed.The formation and evolution characteristics of periodic orbits near these points,including long/short-period orbits,horseshoe orbits,and tadpole orbits,are examined.The relationships between fuel consumption and flying time and between the costs of orbit maintenance and formation flying in missions targeting triangular libration points are investigated,and the theoretical,technical,and engineering challenges faced by such missions are evaluated.In practical applications,triangular libration points provide ideal platforms for deep space observation,gravitational wave detection,and space infrastructure deployment.关键词
