Hello, so I am building a small turbine engine and i need to know the best angle for the blades. Any help would be very helpful, thank you.
Experimenting with gas turbines can be very dangerous. If you must experiment, I would recommend you initially follow other experimenters by modifying the turbocharger from a petrol vehicle
This is when the chemistry comes into play. A lean burn is oxidising so it precludes the use of many metals in the turbine. It also requires compression of air that will not be used efficiently.AlephZero said:"lean" combustion with an excess of air to reduce the exit gas temperature

You missed my point entirely, I did not consider NOx. Oxidation of the turbine material can be a real problem with the wrong turbine material / exhaust chemistry.AlephZero said:For a 3 in diameter engine, I don't think the OP is going to be worried about meeting NOx emission standards on the first prototype!
Will the exhaust gas continue to expand after combustion? If so I could use the same principal as a fish gill and use the increase in volume of the gas in conjunction with an increase in the diameter of the turbine. Ie. Make it sort of cone shaped.
