Pressure fed liquid bipropellant engine |
|
This engine uses liquid oxygen as the oxidizer and kerosene or gasoline or liquid propane as the fuel. The engine is made out of brass or copper tubes and is regeneratively cooled by the propellant. Helium is used to pressurize the propellants. Here are some useful links: Pyrotechnic Valves: http://home.iae.nl/users/nero/pyro/pyrovalv.html http://www.comcen.com.au/~pkelly/pyrovalves.htm |

Auto vent valves for cryogenic propellants, propellant vents until pyrovalve upstream fires releasing pressure which pushes the teflon slider to the vent hole, sealing the system. From: http://home.iae.nl/users/nero/pyro/pyrovalv.html |

High pressure design with o-rings on the cylinder instead of on the moving piston. This means that orings don't need to move and wont shear with high pressures. From: http://home.iae.nl/users/nero/pyro/pyrovalv.html |
