The invention belongs to the technical field of aircraft landing gear design, and particularly relates to a main landing gear for takeoff and landing of an aircraft and a takeoff and landing method of the main landing gear. The main landing gear for takeoff and landing is designed to replace an existing main landing gear and is connected to the bottom of an aircraft body in the takeoff and landing process of the aircraft to assist takeoff and landing of the aircraft; when the aircraft flies in the air, a main undercarriage is not carried, so that the weight of the aircraft flying in the air can be reduced, the oil consumption of the aircraft is reduced, the obstacle crossing ability of an aircraft route is improved, an undercarriage cabin with a large size does not need to be arranged in the middle of the aircraft, the occupation of the internal space of the aircraft can be reduced, the design constraint of an aircraft body is reduced, and the difficulty of aircraft layout design is reduced; the aerodynamic resistance of the aircraft flying in the air can be reduced, and the cruise Mach number of the aircraft is increased.

    本申请属于飞机起落架设计技术领域,具体涉及一种飞机起飞着陆用主起落架及其起飞着陆方法,设计以起飞用主起落架、着陆用主起落架取代现有的主起落架,在飞机起飞、着陆过程中连接到飞机机体底部,辅助飞机起飞、着陆,飞机起飞后,在空中飞行时,不携带主起落架,以此可降低飞机空中飞行的重量,降低飞机油耗,提升飞机航线越障能力,且无需再在飞机中部布置体积较大的起落架舱,可降低对飞机内部空间的占用,降低飞机机体的设计约束,降低飞机布局设计的难度,以及能够降低飞机空中飞行的气动阻力,提高飞机的巡航马赫数。
