The design of Airbus A321 is based on A320, but it has been lengthened to increase the fuselage length and provide more seats and space. Compared with A320, the number of seats in A321 has increased by about 24% and the space has increased by 40%. In order to adapt to the larger fuselage and increased weight, the wing area of A321 is slightly enlarged and the landing gear is reinforced. In addition, A321 uses high-thrust CFM56 and V2500 engines.
In the service of airlines, Airbus A321 is usually used as a flight mission on medium-haul routes, which can accommodate more passengers and provide a comfortable flight experience. For example, the A321 of China International Airlines can accommodate about 300 people, which is suitable for domestic and foreign travelers.
In addition, Airbus A321 has some modern improvements, such as some models equipped with shark fins to improve flight efficiency. These winglets can reduce air resistance, thus reducing fuel consumption and carbon emissions.
To sum up, Airbus A321 is a passenger plane with high capacity and modern design, which is suitable for short and medium-haul routes.
