摘要： The downstream end portions of the inner and outer walls of the combustion chamber of the gas turbine are pressed against the inner and outer platforms respectively of the vanes of the high pressure turbine nozzle and they extend thereover substantially to the downstream end of the platforms, and the means for mechanically connecting the turbine nozzle to the downstream end portions of the combustion chamber walls are formed by connection screws implanted in the airfoils of the vanes of the turbine nozzle, passing through holes formed in the end portions of the combustion chamber walls. Thus, the downstream end portions of the combustion chamber walls contribute to preventing leakage from the gas stream at the interface between the chamber and the nozzle, and also along the nozzle.
