Question: 2 for a space shuttle in a 300 km altitude...

Question details

2. For a space shuttle in a 300 km altitude circular orbit, calculate the orbital speed. What is the Δν required to attain escape speed, i.e., to insert the shuttle on a parabolic orbit? Compute the required propellant mass, assuming the shuttles Orbital Maneuvering System -- hypergolic liquid-propellant rocket engines with ls 316s - is used for this insertion maneuver. Use Eq. (11.26), neglecting gravity and drag losses. For mo use the empty weight 68,585 kg plus a 10,000 kg payload plus the required propellant mass to be calculated(11.26)
