The invention belongs to the field of aircraft cabin door structure design, and particularly relates to an aircraft mission cabin door structure. Comprising a foam sandwich core, an inner skin arranged on the inner side of the foam sandwich core and an outer skin arranged on the outer side of the foam sandwich core; the multiple groups of cabin door hinges are fixedly connected with the cabin door main body through bolts; the locking ring comprises a front locking ring and a rear locking ring, the front locking ring is fixedly installed at the front end of the cabin door body through a bolt, and the front locking ring is matched with a front locking device on a fuselage fixing structure to achieve cabin door locking; the rear locking ring is fixedly installed at the rear end of the cabin door body through a bolt, and the rear locking ring is matched with a rear locking device on a fuselage fixing structure to achieve cabin door locking. According to the aircraft mission cabin door structure, the current space and rigidity requirements can be met, the cabin door structure and the hinge occupy small space, and the cabin door rigidity meets the requirement in the full-height flight state of an aircraft.

    本申请属于飞机舱门结构设计领域,特别涉及一种飞机任务舱门结构。包括:所述舱门主体具有预定弧度,包括泡沫夹芯,还包括设置在所述泡沫夹芯内侧的内蒙皮,以及设置在所述泡沫夹芯外侧的外蒙皮;多组所述舱门铰链通过螺栓与所述舱门主体固定连接;锁环包括前锁环和后锁环,其中,所述前锁环通过螺栓固定安装在所述舱门主体的前端,所述前锁环与机身固定结构上的前锁定装置配合实现舱门锁定;所述后锁环通过螺栓固定安装在所述舱门主体的后端,所述后锁环与机身固定结构上的后锁定装置配合实现舱门锁定。本申请的飞机任务舱门结构,可以满足当前空间、刚度要求,舱门结构和铰链占用空间小,舱门刚度在飞机全高度飞行状态下满足要求。
