Hohmann-like Transfer

Definition

A two-impulse Earth-to-libration-point transfer analogous to the Hohmann transfer. The apogee of an Earth orbit is raised to the altitude of the target libration point orbit, followed by an orbit insertion maneuver. Simple but expensive for EML2 due to velocity mismatch at arrival.

Application Value

在进行轨道转移设计时，This概念有助于评估转移代价和飞行时间，为任务方案比选provides定量依据。结合全局搜索算法，可找到多族解和帕累托前沿，指导轨道设计决策。
