摘要：

The combination of lunar gravity assists for Earth escape and similar to 1.25 yr. of SEP V-infinity leveraging effectively boosts the performance of a given launch vehicle. Two methods are available to establish a launch period with lunar gravity assists, where the energy achievable with lunar escape has been characterized as a function of right ascension, declination, and launch energy. The increased launch efficiency makes a Falcon 9 perform like an Atlas V (401) at low C-3 or like an Atlas V (531) at high C-3. An Atlas V (551) outperforms a Delta IV Heavy for C-3 above 24 km(2)/s(2).
