Rocketscience The team behind Australia's attempt at the land speed record - the Aussie Invader 5R - has received its first two composite- wound ablative rocket nozzles. The motors, which are on loan to the team, have been test fired to establish maximum sea-level thrust ratings, nozzle erosion duration and thrust ratings for various given injector feed pressures. The team is now establishing gaseous helium, liquid oxygen and bio kerosene payloads to determine final pressure vessel sizes.
