The invention relates to the technical field of aircraft structure design, in particular to an aircraft cargo hold floor structure and an aircraft. The invention provides an aircraft cargo hold floor structure. The aircraft cargo hold floor structure comprises a high web frame and shear angle pieces. The high web frame is provided with a frame web and a frame edge strip; the frame web is of a plate-shaped structure, compared with a traditional stand column structure, the plate-shaped structure is higher in structural stability, further, the high-web frame structure has higher bending rigidity, and when the high-web frame structure is applied to the lower portion of a cargo hold floor with the bottom of a fuselage large in appearance curvature change, the rigidity of the cargo hold floor is improved. The bottom structure can well cope with the situation that the bottom structure expands unevenly under the action of airtight loads, the appearance of the fuselage is maintained, the problem that the safety margin is insufficient due to the fact that the bending moment of the bottom of the fuselage is too large is effectively solved, and the safety and reliability of the structure are guaranteed. The aircraft provided by the embodiment of the invention also has the technical effects as the aircraft comprises the cargo hold floor structure of the aircraft.
本申请涉及飞机结构设计技术领域,尤其涉及一种飞行器货舱地板结构及飞行器。本申请提供的飞行器货舱地板结构,包括高腹板框以及剪切角片;高腹板框具有框腹板和框缘条;将框腹板为板状结构,相较于传统的立柱结构,板状结构的结构稳定性更强,进一步本申请提供的高腹板框结构具有较高的抗弯刚度,当应用于机身底部外形曲率变化较大的货舱地板下部时,可以很好地应对底部结构在气密载荷作用下会出现膨胀不均匀情况,维持住机身外形,有效地解决了机身底部弯矩过大导致的安全裕度不足的问题,保证了结构的安全可靠性。本申请实施例提供的飞行器,由于包括上述的飞行器货舱地板结构,因此也具有上述的技术效果。
