Abstract: A full admission radial impulse turbine and turbines with full admission radial impulse stages.

Abstract: A full admission radial impulse turbine and turbines with full admission radial impulse stages. The last-mentioned turbines are of the single shaft, dual pressure type. Provision is made for utilizing working fluid exhausted from the high pressure section, in which the radial impulse stage(s) are located, in the low pressure section which contains axial flow turbine stages. The (or each) radial impulse stage in the dual pressure turbine has a rotor or wheel with buckets or pockets oriented transversely to the direction of wheel rotation and opening onto the periphery of the wheel. Working fluid is supplied to the buckets via nozzles formed in, or supported from, a nozzle ring surrounding the turbine wheel and aligned with the entrance ends of the buckets.

Abstract: Gas turbine engines with interfaces between a compressor and a combustor which minimize disturbances in the pattern of air flowing from the compressor to the combustor. Provision is also made for dissipating disturbances which may have been created and for supplying compressor discharge air to the turbine of the engine to cool specified turbine components.
