Abstract
A radial flow centrifugal impeller comprising an even number of re-heat flow ports, a main engine flow port, and a drive shaft having a helical impeller arrangement provided on its circumference and impeller blades mounted on the circumference of the helical impeller arrangement, each impeller blade having a flat peripheral first portion adjacent each re-heat flow port and a flat peripheral second portion adjacent the main engine flow port, the ratio of the size of the first portions on all the impeller blades to the size of the second portions on all the impeller blades being effective to control the ratio of the fuel flowing through the re-heat flow ports and the main engine flow port, and the re-heat flow ports being symmetrically disposed about the radial flow centrifugal impeller.
