描述了一种用于数值确定两个不同日心轨道中两个位置之间的最佳二脉冲传递的方法。这些公式基于 McCue 和 Bender (1965) 的早期工作，用于在绕地球的两个轨道之间实现最佳双脉冲传输。最小总 Delta-V（发射时的 Delta-V 加上在目标体上实现给定最终轨道的 Delta-V）等值线绘制在发射体发射时的真实异常值和目标体到达时的真实异常值轴上。获得的最佳转移是“时间开放的”，并且使用修补二次曲线找到从初始轨道到最终轨道的 Delta-V。这些“主肋”图对于在任务设计的早期阶段选择初始条件非常有用。
A method for numerically determining the optimum two-impulse transfer between two positions in two different heliocentric orbits is described. The formulas are based on earlier work by McCue and Bender (1965) for optimum two-impulse transfers between two orbits about the earth. The contours of minimum total Delta-V(Delta-V to launch plus Delta-V to achieve a given final orbit at the target body) are plotted on axes of true anomaly of the launch body at launch and true anomaly of the target body at arrival. The optimum transfers obtained are 'time-open' and the Delta-V from the initial orbit to the final orbit is found using patched conics. These 'prime rib' plots are useful for selecting initial conditions in the early phases of mission design.
