ABSTRACT:
A thermal regenerative injector 10 for a rocket engine that transfers heat from a fuel after turbine operation to the fuel prior to turbine operation, thereby providing a higher chamber pressure and lower fuel pump pressure. The injector 10 has a plurality of elements 44 having concentric channels 78, 80, and 82 separated by sleeves 66, 68, and 70, the fuels flowing therethrough, heat being transferred through a common middle sleeve 68, The cold fuel, after being so heated, is heated further in the typical fashion of routing it through the combustion zone and nozzle cooling jackets 16 and 20.
