Abstract
Abstract A gas-turbine plant in which the turbine in enclosed in an annular combustion chamber and the inlet portion of the stator of the turbine is connected to the stator of the compressor through the intermediary of the body of the diffusor in such a manner that it is possible to compensate temperature deformations of said body of the diffusor and stator of the turbine. To obtain a compact plant possessing good operating characteristics use is made of a compressor whose first stage is made diagonal and whose subsequent stages are axial.
