powered by turbofan engines These engines are significantly more efficient than earlier turbojet designs A typical turbofan engine comprises several key components 1 Fan The large frontfacing fan draws in a significant amount of air a portion of which bypasses the core engine improving fuel efficiency 2 LowPressure Compressor Further compresses the bypassed air 3 HighPressure Compressor Compresses the remaining air which is then directed to the combustion chamber 4 Combustion Chamber Fuel is injected and ignited creating hightemperature high 2 pressure gas 5 HighPressure Turbine Extracts energy from the hot gas to drive the highpressure compressor 6 LowPressure Turbine Extracts remaining energy to drive the fan and lowpressure compressor 7 Nozzle Expands and accelerates the hot gases generating thrust Figure 1 Simplified Diagram of a Turbofan Engine Insert a clearly labeled diagram here showing the components listed above III Performance Characteristics and Key
