Sliding vane turbomachine - from which combustion gases are cleared over three phases before new gas is forced into combustion chamber

摘要

The turbomachine has a rotor mounted on bearings in inner plates, the rotor carrying sliding vanes. Preheated charging air is taken from a branch pipe of the cooling air outlet via filters to the air inlet and the combustion chambers. An outlet is mounted directly on the air inlet. The change of charge is carried out in three phases. The outlet gases can escape during the first phase, during the second phase the remaining gases are expelled by fast flowing compressed air and during the third phase clean air is forced into the combustion chamber.
