The TwoBody Problem in Aircraft

The TwoBody Problem in Aircraft
... r)(r − rp ) We can the integral by using the substitution r = a(1 − e cos η) Then dr = ae sin η dη and − r = ae(1 + cos η), r − rp = ae(1 − cos η) so the denominator is ae sin η The result is t ... L2 GM r+ −r − 2E 2E GM r (23) − (24) But the solutions to this quadratic in r are known, since vr = at the two turning points of the orbit, corresponding to pericenter, θ = θ0 , r = rp = a(1 ... and the radial equation (8) becomes F (1/u) d2 u +u = − dθ L2 u2 (10) The first integral of this equation, obtained by multiplying by du/dθ and integrating wth respect to θ (and noting that...
