    • An aircrfat landing wheel rotating means has an airscoop (21) mounted on the undercarriage unit (10) between a pair of landing wheels (16) fitted with tyres (14). A wheel outlet (25) in each side of the airscoop (21) directs the airflow over turbine blades (20) formed integrally with the landing wheels (16) as spokes interconnecting the rims to the wheel hubs (15) (which incorporate disc breaking systems). The airscoop (21) has a rearward venting outlet (24) which is selectively closed by hinged doors (29) and/or flaps (34) to direct the airflow to the turbine blades (20) or opened to allow a portion of the airflow to bypass the turbine blades (20) and so reduce the drag produced by the airscoop as the undercarriage unit (10) is lowered prior to landing or on take-off.
    • 空气着陆轮旋转装置具有安装在一个装配有轮胎(14)的一对着陆轮(16)之间的底架单元(10)上的空气调节器(21)。 在飞机(21)的每一侧中的轮出口(25)将气流引导到与着陆轮(16)一体形成的涡轮机叶片(20)上,作为将轮辋与轮毂相互连接的轮辐(15) 系统)。 该空气调节器(21)具有后部通风出口(24),该后部通风出口通过铰链门(29)和/或翼片(34)选择性地关闭,以将气流引导至涡轮叶片(20)或打开以允许一部分气流 以绕过涡轮机叶片(20)并且因此在着陆或起飞之前降低当底架单元(10)降低时由空气滤清器产生的阻力。
