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.
Baluncore said: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!
iwant2beoz said: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.
The blade angle in a turbine engine is designed to efficiently convert the energy of the hot gases into rotational energy to power the engine. The angle is carefully designed to optimize the airflow and maximize the engine's performance.
The blade angle in a turbine engine is determined through a combination of theoretical calculations and experimental testing. Engineers use complex design software and physical models to calculate the most efficient angle for each blade based on the engine's specific requirements.
The blade angle is a critical factor in the engine's performance. A smaller angle can lead to a higher pressure and temperature difference across the blade, resulting in greater energy conversion. However, a larger angle can improve the engine's stability and reduce the risk of blade failure. Finding the right balance is crucial for optimal performance.
Yes, the blade angle can be adjusted in a turbine engine. This is typically done through variable stator vanes, which can change the angle of the airflow entering the rotor blades. This allows the engine to adapt to different operating conditions and improve efficiency.
If the blade angle is not properly maintained, it can lead to reduced engine performance, increased fuel consumption, and potential damage to the engine. A small deviation from the optimal angle can significantly impact the engine's efficiency, so regular maintenance and adjustments are critical for optimal performance and safety.
