Injector finished

We have finished machining the injector for the Pyralis rocket engine. The injector is the most mechanically complex part of the engine. Fuel and oxidizer pipes tap into the injector, and channels within the injector route the propellants to a ring of six injector heads. Within each injector head, the propellants are mixed together and sprayed out of the injector into the combustion chamber at high speed. The injector also contains mounting points for the three load cells that will connect the engine to the test stand, holds the spark plug igniter, and has a pressure tap for measuring chamber pressure. Finally, the injector has numerous seals within itself and with other components to prevent leaks.
