The invention relates to a landing gear bay, comprising a bottom wall (46) comprising longitudinal beams (52.1-52.8) and a panel (60, 60 ') arranged between the longitudinal beams (52.1-52.8). At least one panel (60, 60, 60 '') forming a sealing barrier between a first zone (Z1) and a second zone (Z2) on both sides of the longitudinal beams (52.1-52.8), said panel (60, 60 ', 60' ') having a first longitudinal edge (60.1) and a second longitudinal edge (60.2), each connected to one of the longitudinal beams (52.1-52.8), the second zone (Z2) being adapted to withstand a greater pressure than the first zone (Z1); the invention is characterized in that the panel (60, 60 ', 60' ') has a substantially constant profile in the longitudinal direction and comprises at least one central portion which is offset towards the second area (Z2) compared to the first (60.1) and second (60.2) longitudinal edges thereof. This solution can limit the vertical stresses exerted on the stringer due to the pressure difference between the first zone (Z1) and the second zone (Z2). The invention also relates to an aircraft comprising said landing gear bay.
本发明涉及一种起落架舱,包括底壁(46),其包括纵梁(52.1‑52.8)以及在设置于面板(60,60’,60”)的两侧的第一区域(Z1)和第二区域(Z2)之间形成密封屏障的至少一个面板(60,60,60”),所述面板(60,60’,60”)具有第一纵向边缘(60.1)和第二纵向边缘(60.2),其各自连接至纵梁(52.1‑52.8)中的一个,第二区域(Z2)适于承受大于第一区域(Z1)的压力;其特征在于,面板(60,60’,60”)在纵向方向上具有基本不变的轮廓并包括至少一个中心部分,该中心部分相比于其第一纵向边缘(60.1)和第二纵向边缘(60.2)朝向第二区域(Z2)偏移。这种解决方案可以限制由于第一区域(Z1)和第二区域(Z2)之间的压力差而施加在纵梁上的竖直应力。本发明还涉及一种包括所述起落架舱的飞行器。
