Research on spacecraft long-range optimal interception
摘要
Abstract
Finite thrust and impulse thrust are two kinds of methods of studying spacecraft orbital interception. Equations of relative motion during spacecraft interception were built based on C-W equations,and it was nondimensionalized. In this paper, with fuel-consumption as performance index,the interception trajectory is optimized using Legendre pseudospectral method,and the results were analyzed. Results show that the method possesses high precision and good robustness for designing spacecraft long-range intercept trajectory. Under the assumption of impulse thrust,a new optimal intercept scheme was proposed based on fixed-time interception theory,and it was characterized by maneuver epoch and needed Delta-V. Both methods were compared and the new scheme of interception could satisfy the requirement of mission flexibly.关键词
