Path: Orbit/OrbitManeuver
% Computes the delta-V for reentry from a near-circular orbit. You must select the entry interface radius, rEI and c! and c2 which are the LTVCON (Linear Terminal Velocity Constraint) constants such that vR = c1 + c2*vH where vR is the radial velocity and vH is the horizontal velocity Since version 8. -------------------------------------------------------------------------- Form: dV = DVReentry( a, e, rEI, c1, c2, mu ) -------------------------------------------------------------------------- ------ Inputs ------ a (1,1) Semi-major axis of initial orbit e (1,1) Eccentricity of the initial orbit rEI (1,1) Radius of entry interface c1 (1,1) LTVCON 1 c2 (1,1) LTVCON 2 mu (1,1) Gravitational constant ------- Outputs ------- dV (1,1) Required velocity change -------------------------------------------------------------------------- Reference: Bond, V.
