A nonpositive displacement mechanical device designed to provide cool air in aircraft air conditioning systems. Cool air or reduction in temperature is obtained when the heat or energy of compressed air is removed by converting it to work or mechanical energy to drive an impeller wheel. Compressed air is directed through nozzle vanes and impinged upon the blades of a turbine wheel creating rotary motion which drives an impeller wheel. Consists of an impeller wheel, a turbine wheel matched with a nozzle ring on a bearing mounted shaft within a scroll type housing(s).
