Definition

A shape function construction method proposed in this paper. It assumes that the amplitudes and phases of the approximate periodic orbit solution near libration points vary polynomially with time, thereby fitting the spiral characteristics of low-thrust transfer trajectories. The linear assumption is the simplest form; higher-order polynomials can approximate more complex transfer paths.

Application Value

This term has application value in the design and analysis of cislunar space missions, supporting trajectory design, mission planning, and system optimization. Researchers can analyze its physical mechanisms and engineering applicability based on specific mission requirements to advance cislunar space exploration technology.
