MODELLING AND DESIGNING OF A TURBOFAN ENGINE WITH MORE ENHANCED OVERALL ENGINE EFFICIENCY DURING OPERATION

In the current study, a turbofan engine design was model for optimal overall efficiency during engine operation. This was achieved by modelling the parameters of the engine thrust and the total system efficiency during v arying heat transfer process, kinematic processes and flow velocities that are used to propel the aircraft. The main parameter being model was the propulsion efficiency being modelled as a proportion of the system mechanical energy being used to propel the system. The tool of EngineSim was used to modelled the derived models being developed for a design of a turbofan engine with more enhanced overall efficiency. The models focused on the turbofan efficiency and the critical parameter such as propulsion efficiency was model for optimal operation. the model derived were simulated by EngineSim version and the derived models were tested through the empirical simulation of the turbofan engine for the purposes of critical system observation and analysing the system performance during operation. The turbofan engine thrust was being iterated during EngineSim simulation process changing the values of the different engine parameters. It was shown that, the thrust produced by the simulation impacted the propulsion efficiency which gave varying system performance and overall efficiency of the designed system. It was also revealed that, the design turbofan can produce enough kinetic energy to propel the airplane to move forward.
