HOW to DESIGN & BUILD SMALL LIQUID-FUEL ROCKET ENGINES
The rocket engine is a relatively simple device in which propellants are burned and the resulting high pressure gases are expanded through a specially shaped nozzle to produce
thrust. Gas pressurized propellant tanks and simple propellant flow controls make operation of a small liquid-fuel rocket engine about as simple as operating an automobile
engine. Why then do so many amateur rocket engines fail or cause injury? The reason, usually and simply, is that the amateur is not accustomed to high pressure devices
operating near material temperature limits. His normal everyday life is, instead, filled with devices and gadgets operating at low pressures and at low thermal energy levels. With
proper design, careful workmanship, and good test equipment, operated in a safe manner, the amateur can build small, liquid-fuel rocket engines which will have hours of safe
operating life. This will provide you with design information, fabrication procedures, test equipement requirements, and safe oeprating procedures for small liquid-fuel rocket
engines, so you can build your own liquid fuel rocket.
