Advice on radial inflow turbine

[jpolihro]

Hello All,

where could one purchase a radial inflow turbine wheel and its manifold/nozzle assembly? I looked on the net but all I could find is this link.

Would someone know what is the cost of such assembly for a turbine wheel with radius of 6cm (cold flow, about room temperature gas)? We need the turbine wheel and manifold, but do not require burner/generator modules.

Many thanks.

What power?
What air speed and temperature and pressure at the "standard" inlet conditions?
Fixed installation (for power production), or mobile (auto, truck, train, missile, airplane)?
What lifetime? (Many years or one-time use or only two or three times use?)
What is important? (Minimum weight, minimum cost, minimum size, minimum fuel economy, maximum lifetime, maximum reliability?)
Home or garage-type "Owner-operator" maintenance, hobby applicatin, or professional airframe & mechanical aerospace worker or NASA or military?

Could you accept a "used" ex-military power plant from an old missile?
Have you checked overseas (Russia, the Ukraine, Slovak or Poland or Czech Republic) for an older jet or missile power plant from their surplus?

Hi racookpe1978,

Power: in the order of hundreds of watts, up to a kilowatt.
At Inlet: room temperature + up to 100K; pressure of 2-5atm gauge; subsonic nozzle injection. Tip speed of the rotor is subsonic, but should be capable of reaching about 300-330 m/s (50,000 rpm at 12cm diameter).
Rig: for testing purposes in a lab only, to demonstrate output power from radial inflow turbine.
Lifetime: longer is better, but as this is for demonstration purposes only, durability is less important.
What is needed: minimum size and possibly minimum weight.
Setting: university lab.

Thanks!
