Preliminary Design Review (by the end of October)
Design Phase (next step)
Three types of possible injectors:
Pintle Injector - As used in many liquid-propelled rockets.
Coaxial Injectors - Previously used in hybrid-propelled rockets
Showerhead Injectors - Also Previously used in hybrid-propelled rockets.
Pintle Injector:
Pros:
Throttleable
Easy to manufacture
Good mixing for bi-propellant systems
Cons:
Increased complexity for mono-prop injection
Atomized propellant at the top of the case which decreases velocity
Doesn't allow propellant to evenly distribute into fuel grain geometry
Coaxial Injector:
