WebFan-Jet. How does a turbofan engine create thrust? A gas turbine engine that has a separate turbine to drive a fan section to produce thrust. The fan section of a turbofan engine produces what percentage fo teh engines total thrust? 80 %. On a turboprop engine what keeps the propeller from windmilling when the engine is shut down? WebThe engine property of a turboprop and turbo-shaft engine is quite similar. The primary difference is the design base as per its usage. The turboprop version needs to be designed in such a way that it supports the load of the attached propeller. While the design of turboprop the load of the propeller is supported by the design of the aircraft.
