This is my idea about Airbus's new medium-sized wide-body machine in the future (to replace the current A321Neo and A321XLR). On the basis of retaining the original design of A310-300, the effect is achieved by replacing the engine and structural materials. By replacing the engine with GEnx of General Electric, the fuel efficiency is improved by at least 20%, and the noise is reduced by 25%, which can better meet the complex and changeable route requirements. In terms of materials, the maximum takeoff weight is improved by replacing the main structure with composite materials and applying carbon fiber materials on the wing. By adding several central fuel tanks in the middle of the wing and a brand-new central fuel tank in the rear of the fuselage, the voyage is improved to a certain extent, second only to A330neo, which maintains the original number of seats.The cockpit benefits from the application of new technology, which makes the electrification and intelligence far ahead.If Airbus really produces this model in the future, will you consider taking it?
