Unformatted text preview: Tyler Campos ECE-2984 HW6 1) Perigee (when point in orbit is closest to the earth) 2) Thermodynamic and Electrodynamic 3) Over-expansion happens where shock waves created at the nozzle tip convert kinetic energy to thermodynamic energy which decreases exhaust velocity and thrust 4) Liquid hydrogen and liquid oxygen 5) 2 6) At a node (where the path crosses the equatorial plane 7) Mechanical energy divided by the mass. Energy is defined by the specific orbit rather than the vehicle in orbit 8) Prograde motion is where the satellite orbits in the same directional movement as the planets rotation. Retrograde motion is where the satellite orbits in the opposite motion of the planets rotation (retrograde motion) 9) From it’s ground track, eastward moving spacecraft reach the highest latitude during inclination 10) The rendezvous “lead angle” is 180 degrees minus the final angle between the satellite and the shuttle. The lead angle is the angle from that plane where that angle can be used to determine what ∆V...
