i want to make a small aeroplane turbine . i need help. please?

Question

i have seen on discovery channel a mini aeroplane turbine that works. but i want to build it . i need your help. thanks

Answer 1

You can probably buy a kit for $20,000 or so. The materials and machining required to make one would be beyond what you could do or ever afford. If not made with the right materials and balanced perfectly, they tend to disintegrate and throw shrapnel all over.

Answer 2

At the left of the engine is the turbine section. There can be two sets of turbines. The first set directly drives the compressor. The turbines, the shaft and the compressor all turn as a single unit. At the far left is a final turbine stage, with a single set of vanes. It drives the output shaft. This final turbine stage and the output shaft are a completely stand-alone, freewheeling unit. They spin freely without any connection to the rest of the engine.

Large jetliners use what are known as turbofan engines, which are nothing more than gas turbines combined with a large fan at the front of the engine. The difference is that the final turbine stage drives a shaft that makes its way back to the front of the engine to power the fan. The purpose of the fan is to dramatically increase the amount of air moving through the engine, and therefore increase the engine's thrust. When you look into the engine of a commercial jet at the airport, what you see is this fan at the front of the engine. It is huge -- on the order of 10 feet (3 m) in diameter on big jets, so it can move a lot of air.
The air that the fan moves is called "bypass air" because it bypasses the turbine portion of the engine and moves straight through to the back of the nacelle at high speed to provide thrust.

Compressor - Compresses the incoming air to high pressure
Combustion area - Burns the fuel and produces high-pressure, high-velocity gas
Turbine - Extracts the energy from the high-pressure, high-velocity gas flowing from the combustion chamber

The compressor is basically a cone-shaped cylinder with small fan blades attached in rows as the air is forced through the compression stage its pressure rises significantly. In some engines, the pressure of the air can rise by a factor of 30.
