How to make a small turbine engine?

I can't stand it anymore, so let's say a few words:

If you're an enthusiast, and you're very, very, very, very rich, and you don't have anything to make your own turbochargers, that's a hobby;

If you want to save money, buy ready-made ones to save the most money;

It is estimated that the car factory will develop a supercharger in the face of large-scale and long-term cooperation in the future, and a symbolic development fee of 1.8 million yuan (it cannot be brand-new, only modify the interface), and the prototype stage will cost tens of thousands of yuan.

You do it yourself, I think the quality requirements are minimized, and you can make one that can be turned for more than 10 minutes:

The parts are all made of rapid prototyping, and I assume that you have your own design drawings, in fact, my assumption is ridiculous, and people with design drawings will not come here to ask this question at all:

High nickel shell, use fast mold, only one one, count you 250,000;

Turbines and shafts, gasoline engines, you'd better go to France to do it, to the UK for processing, you can't find it in China; Just if the chairman of the company is your relative, he is willing to do it for you, symbolically even if you are 10,000; And then, then, what are you going to do with those little parts, I died of a headache.

In short, in this matter, there is no billions of net worth, so it is better to buy a ready-made one, and then change the engine, I think it will save a little.

Don't understand? The wiper motor does not consume much energy, so why get an engine? The engine also has to bring another generator** wiper motor power supply??

It is advisable to go to a hardware store and maybe there are ready-made micro generator sets.

It's harder. First, you have to understand the structure of this engine yourself.

Second, how big of an engine are you going to make?

Third, the pump can be centrifugal type, not axial flow type, axial flow type is quiet design and manufacturing requirements are very high, and the speed is much higher than that of centrifugal type to achieve the same pressure.

Fourth, if you want to make the old scum structure, then the starter can be directly connected to the shaft of the compressor with an electric motor, and then moved away after starting. The lubricating oil can be supplied with an electric oil pump, and the oil pump is not driven by the power of the engine, and similarly, the fuel pump is also electric. Of course, this is only a scheme for thrust engines.

If it is used for general engines, then as long as the shaft of the engine is lengthened, output in front, and then decelerate with a reducer.

Fifth, the turbine of the engine should be resistant to high temperatures. General steel is not good, and the design and processing of turbines are also very laborious. It directly affects the engine output power.

Sixth, it is better not to use gasoline for fuel. Because it is homemade, gasoline is not safe enough. Diesel or kerosene can be used.

Seventh, the combustion chamber should be made of high-temperature resistant materials.

8. The bearing should be kept as far away from the combustion chamber as possible. And use high-temperature bearings.

For the rest of the stuff, let's take a good look at the book.

It is recommended not to make yourself, the steel is not up to standard, and the centrifugal force will produce **, and the power is not inferior to that of a grenade.
