Although similar in concept a big difference between the FIAT and the Rotodyne was the FIAT had a gas turbine feeding cold tip jets whereas the Rotodyne had compressors driven by the main engines feeding hot tip jets where fuel was added and combustion took place in the tip nozzle which is why it was so noisy.
