VELOCITY REQUIREMENTS FOR TRANSFER BETWEEN CO-PLANAR, CO-AXIAL ORBITS

Abstract

The total velocity requirements for coplanar, cotangential transfer between orbits with a common major diameter are examined. The results are valid for ascending, descending, intersecting,AND NON-INTERSECTING ORBITS. Computational results obtained using the AFIT IBM 1620 computer are presented for elliptic, parabolic, and hyperbolic outer orbits as a function of the transfer and outer orbit geometries. For the parabolic outer orbit, he maximum velocity requirement is 18% greater than the escape velocity at the periapsis of the transfer orbit when the transfer orbit has an eccentricity of 0.73. Fo hyperbolic orbits, maximum velocity requirements occur at particular elliptical transfer orbits where the velocities at infinity (i.e., the hyperbolic excess), are less than one third the reference escape velocity.
