The invention relates to an aircraft wheel drive device comprising: a ram air turbine device attached to an aircraft landing gear and capable of being driven by air to provide a driving force; a transmission device drivingly connected to the ram air turbine device; and a hub drive drivingly coupled between the transmission and the wheel, where the wheel can be driven in rotation by the ram air turbine device via the transmission and the hub drive. Therefore, energy is provided for the hub driving device through the ram air turbine device, so that the hub of the undercarriage can be directly or indirectly driven to rotate without depending on an aircraft power supply system, and then wheels can be pre-accelerated before the aircraft lands, so that tires are smoothly grounded, and sliding friction and additional impact of the tires are reduced. In addition, the invention also relates to a wheel speed control system and a control method.

    本发明涉及一种飞行器轮子驱动装置,该飞行器轮子驱动装置包括:冲压空气涡轮装置,冲压空气涡轮装置附连到飞行器起落架并且能够被空气驱动以提供驱动力;传动装置,传动装置驱动地连接到冲压空气涡轮装置;以及轮毂驱动装置,轮毂驱动装置驱动地联接在传动装置和轮子之间,其中,轮子能够经由传动装置和轮毂驱动装置被冲压空气涡轮装置驱动旋转。这样,通过冲压空气涡轮装置为轮毂驱动装置提供能量,使得不依赖飞行器电源系统,可直接或间接驱动起落架轮毂转动,进而能够在飞行器降落前给轮子预加速,使轮胎平顺接地,减少轮胎滑动摩擦和额外冲击。另外,本发明还涉及一种轮子速度控制系统及控制方法。
