Abstract
A diffuser for use in a gas turbine engine comprises an inner and an outer annular wall which define a divergent flow passage. The divergent flow passage is divided by a splitter to form two annular flow ducts, of different flow area. Introduction of the splitter into the diffuser to form the two annular flow ducts enables the length of the outer annular wall of the diffuser to be reduced. Reducing the length of the outer annular wall of the diffuser increases the flow area between the diffuser and combustion chamber. Air downstream of the diffuser is therefore unrestricted and moves radially outward to the ports in the head of the combustion chamber with minimum pressure loss.
