That whole thing is a pretty stupid idea except when you realize they did not have back then the materials to make good turbine (hot side) blades that would not melt of stretch. Thus, jet engines were not very efficient at making power and were unreliable. They did not have bypass air, either.

Otherwise, it is madness to see they had such a complex system. Axial compressor into a centrifugal compressor into a combustion chamber* then into the turbine, with an extra ignition chamber for more boost. Then the whole mess drives counter-rotating propellers and there is some thrust from the exhaust out the back.

Anyone can see that as you get to a big turbo charger or turbo compounder, it is just a logical extension to get rid of the heavy, complex reciprocating engine and make a nice smooth, light, simple, axial flow turbine.

* combustion chamber = 12 cylinder diesel engine
