NTSH Gas turbine
Fascinated by jet engine propulsion, we have decided to learn all we can about jet engines. We figure that the best way to explore the principles of a turbojet engine is to build one. We have searched the internet for information on home-built jet engines and found quite a few experimenters in the field. There is a good amount of information available on the subject with all kinds of designs being employed. We want to use these ideas to build a turbojet engine that will be a research test bed for my experimentation. Our goal is to make an engine that is self-sufficient and require no separate power sources to operate thus allowing the unit to be mobile.
Our research has found that most home-built turbojets are built utilizing an gasoline or diesel engine turbocharger. The turbochargers intended function is to use an engines exhaust gas pressure to drive a turbine that in turn drives a centrifugal air compressor. This air compressor forces air into the combustion cylinders allowing more fuel to be burned per combustion thus creating more horsepower from the same displacement engine. In a home-built turbojet application, the turbochargers compressor forces air into a combustion chamber which is mixed with fuel and burned creating hot expanding gasses. These gasses drive the exhaust turbine which in turn drives the compressor thus sustaining the process (a basic jet engine).
