WebThe velocity at periapsis of the capture orbit is found by setting h = r p v p in Equation 2.50 and solving for ν p. (8.59) v p ) capture = μ 2 ( 1 + e ) r p Hence, the required delta-v is WebMay 4, 2024 · This equation will give you the positive values of True Anomaly thanks to the arccos function, where the spacecraft is ascending from periapsis to apoapsis. Flight path angle can now be calculated as ϕ = ± arctan e sin θ 1 + e cos θ If the spacecraft is ascending from periapsis to apoapsis, flight path angle will be positive.
WebNow, we can find the velocity at periapsis of this transfer orbit. In this case r = 7000 km, and a = 13,500 km. We plug these into the Vis-Viva equation to get: v transfer_peri = 9.185 km/s . Then, we can calculate the Δv of the first maneuver: Δv 1 = v transfer_peri - v park = 9.185 km/s - 7.546 km/s = 1.639 km/s WebThe mission calls for a periapsis altitude at Mercury of r p = 122 km.
