A simplified diagram of the propulsion for GOES-R, a weather satellite in GEO is shown. This is a  ______ liquid propellant system that uses a  ______ system to maintain the pressure in the fuel and oxidizer tanks.

The best type of propellant for engines that need to turn and and off multiple times during a mission is     cryogenic (hydrogen) propellant     solid (aluminum) propellant     traditional (kerosene) propellant     hypergolic (hydrazene) propellant

Explain system, control volume and control surface with a diagram.

What differences between ADF and VOR navigation?

explain why non- return/ return less fuel system are used on later model vehcile?

2c) There are many types of traffic control system for the lift system. Give a short account on the following three control systems.  (i) Down collective control; (ii) Directional collective control; and (iii) Group supervisory control.
