Aerodynamic Optimisation of Aircraft Components for Fuel-Efficient Aircraft: Progress in Flaps, Winglets and Engine Configuration

Abstract

With the rise in demand for fuel-efficient aircraft, many people have been exploring how to reduce aerodynamic drag to lower fuel consumption and emissions. The three main parts that affect the aerodynamics and fuel economy of the aircraft are flaps, winglets and engine settings. Aerodynamic mechanisms and Design Trade-offs of the different configurations have been studied in previous experimental and computational work. According to the required size of lift enhancement and flow separation control, the structure of the high-lift device for flaps will also be different. Although the aim of a winglet is to reduce induced drag, it may increase profile drag and other problems with the structure. The other is the arrangement of the nacelle and engine-airframe integration. Increase Propulsion Efficiency and Reduce the Effect of Aerodynamics. Based on the above analysis, it was determined that a single-component Design is not universally ideal. The overall goals of good aircraft design are to improve aerodynamics and structure, meet operational needs, and so on. In the future, with the development of advanced computational methods and multidisciplinary optimisation, the efficiency and sustainability of aircraft will continue to be improved.
