Abstract

The area ruling of an annular diffuser disposed between the compressor and burner of a gas turbine engine is proportioned in a circumferential direction so that the maximum area ruling is adjacent the struts supporting the diffuser walls and the minimum is mid-way between the struts so as to achieve a substantial uniform velocity profile of the exiting air in the circumferential direction.
