Abstract : Relative altitudes of coplanar circular orbits about the earth are investigated for which a bielliptical transfer is more economical than the classical Hohmann transfer, It is found that for transfers between orbits apart by radii-ratios larger than 15.582, the Hohmann transfer it less economical than a bi-elliptical transfer with an intermediate point of altitude larger than that of the larger terminal orbit. The implications of these findings are indicated. (Author)
