A gas turbine engine has conduits leading from the compressor to the turbine for bleeding a portion of compressor air through the turbine blades for cooling or other purposes. A radial pump in the conduits formed by a tangential accelerator and a rotating diffuser transmits the air from the non-rotating environment in the engine to the rotating environment of the turbine rotor. The tangential accelerator accelerates the bleed air to a tangential speed higher than that of the rotor, and the radial diffuser is designed to recover the dynamic pressure or re...


In a gas turine of the type having a compressor section having a flow path from which a fluid working medium such as air is discharged at an elevated pressure to a combustion section where the working medium is combined with a fuel in a combustion process and the products of combustion are directed at high velocity onto a plurality of turbine blades distributed about the periphery of a turbine rotor in a turbine section, improved apparatus for ducting the working medium to the plurality of turbine blades for cooling and other purposes comprising: first c...
