The invention relates to a landing gear assembly, a nose landing gear device, an aircraft, and a method of retracting/deploying landing gear legs. A retractable landing gear assembly 102 for an aircraft 100 has a leg 106 configured to be mounted on an airframe 114 and rotated about a pivot axis 112 between deployed and stowed configurations. A stay assembly is provided for maintaining the landinggear assembly in a deployed, for example down and unlocked, configuration. The stay assembly has a linkage mechanism comprising a first stay (122) and a second stay (124) which are movable between a folded state and an unfolded state (as shown in Figure 2). Room that would otherwise be occupied within a landing gear bay (104) may be freed up above the landing gear leg (106) when in a stowed configuration by means of the stay assembly being unfolded but generally aligned with the length of the landing gear leg, with the stay assembly being mostly positioned beneath the leg.

    本发明涉及起落架组件、前起落架装置、飞行器以及缩回/展开起落架腿部的方法。用于飞行器(100)的可缩回的起落架组件(102)包括安装至机架结构(114)以用于绕枢转轴线(112)旋转的腿部。设置有撑杆组件以用于将起落架组件保持成处于展开的、例如放下且未锁定的构型。撑杆组件具有包括第一撑杆(122)和第二撑杆(124)的连杆机构,所述第一撑杆(122)和第二撑杆(124)可以在折叠状态与伸展状态(如图2中所示)之间移动。可以借助于伸展但与起落架腿部的长度大体对准的撑杆组件来释放起落架舱(104)内的在其他情况下可能被占据的、位于呈收起构型时的起落架腿部(106)上方的空间,其中,撑杆组件大部分定位在腿部下方。
