Abstract:

In this analysis the optimum launching of a body into a nonintersecting hyperbolic orbit by two impulses is presented. The effects of planet rotation and atmospheric drag were not included. The conclusions of this analysis can also be applied to the optimum landing on a planet from a hyperbolic orbit. Only the planar case was investigated, since this is always more economical than the non-planar case. This problem can be defined in terms of three-dimensionless parameters. It was found convenient to use lambda, a and b, where lambda is the ratio of the specific impulse of the first impulse to that of the second, and a and b are the ratios of the radius of the planet to the focal distance to the asymptote and to the perigee of the hyperbolic orbit respectively.
