AAE 532 – Orbital Mechanics Problem Set 10 Due: 11/22/10 Problem 1: Assume that you are investigating future space station concepts. You have been asked to provide information on possible transfer orbits to and from the space station by an OTV (Orbit Transfer Vehicle). The OTV is moved into a circular orbit at 1.5 R . The future space station remains in a coplanar, eccentric orbit such that e = .2 and a = 8 R . Note that the orbits are coplanar. As an example, solve for a transfer such that TOF = 7 hours. (Let ˆˆ ˆ ,, xyz be Earth J2000 equatorial coordinates.) (a) Determine the following characteristics of the transfer: , at yp epe . Use ,,, fgfg ± ± to determine , D A vv . Determine , D A ΔΔ in terms of coordinates; ˆ ˆˆ VCN coordinates. (b) Compute the angles αβφ for implementation of the maneuvers . (So these are the angles that are associated with maneuver orientation.) (c) What phase angle between the vehicles is required at departure?
