Abstract [English]

The fuel efficiency of aero engines is a very crucial aspect that determines the cost of operation and sustainability of the environment in the aviation industry. It examines how complex design and optimization technologies can influence the operation of 100 modern aero engines of turbojet, turbofan and hybrid-electric types. To provide a reference on comparison, baseline performance metrics like fuel consumption, specific fuel consumption and thrust and engine weight were analyzed. Single design interventions such as lightweight materials, aerodynamic designs and thermal management systems were considered with respect to the impact on efficiency and the synergistic effect of combining several interventions were also considered using a compound optimization strategy. The findings showed that integrated optimization led to more than 11 percent decrease in fuel consumption and specific fuel consumption and a minor increase in the thrust-weight ratio, indicating the potential of integrated design methodology. These results can offer practical information in the design of the next generation of fuel-efficient aero engines that can be used to achieve economic and environmental goals in the aviation industry.
