English

Subject field(s)
  • Launchers (Astronautics)
CONT

The Ausroc 3(A3) launch vehicle has a liquid fuelled motor that burns JA-1 kerosene with liquid oxygen, and uses regenerative cooling. The motor produces 35 kN at sea level and has a burn time of 80 seconds. The motor is gimballed to facilitate pitch and yaw control. The wall of the combustion chamber, throat and expansion nozzle consists of 102 stainless steel tubes stacked side by side running parallel to the motor axis. The tubes will be brazed together and the assembly wrapped in a carbon fibre composite. The composite wrapping is used to relieve to tubes of the hoop stress generated by the combustion pressure(2 MPa), whilst the tubes contain the combustion heat(3500 K). The top end of the motor has a kerosene inlet manifolt, oxygen dome and injector block. The kerosene inlet manifold delivers kerosene to every second motor tube, where it travels down to the arse end of the motor. Here it enters the lower kerosene manifold which is a simple plenum ring. This allows the kerosene to flow into the other alternate tubes which deliver it back up to the inlet manifold. The inlet manifold then directs the kerosene to the injector block, which sprays it and the liquid oxygen into the combustion chamber.

Subject field(s)
  • Thermal Insulation
DEF

Insulation material installed between the cell mount of an infrared flame detector and the sighting pipe to reduce heat conduction to the cell.

CONT

Electronic Fuel Injection nozzles and fuel rails are subjected to overheating during vehicles operation... Solution. Install a flat rectangular heat shield between the exhaust manifold and the fuel rail. This shield combines a high temperature ceramic heat block with a more cost effective lower temperature resistant fiberglass insulation. An aluminum foil pad is also added to distribute the heat throughout the insulator alleviating any "hot spots. "
