PREDIFFUSER FOR A GAS TURBINE ENGINE

摘要

Prediffuser For A Gas Turbine Engine A prediffuser, immediately upstream of a dump diffuser for a gas turbine engine is constructed to have equal numbers of struts as there are fuel injectors in the annular combustor. The wedged shaped struts are disposed symmetrically about the annular diffuser. The relatively large blunt trailing edge enhances the circumferential expansion of the discharge air dumping into the dump diffuser which achieves a more uniform temperature profile of the cooling air cooling the burner liner and its associated components, and avoiding localized hot spots.
