The invention provides an air cycle machine and an aircraft air conditioner, and the air cycle machine comprises a fan volute which is provided with a fan wheel cover; the fan blades are assembled in the fan wheel cover and are coaxial with the fan wheel cover; the containing ring is arranged on the outer side of the outer circumferential wall of the fan wheel cover in a sleeving mode, and a sealed containing annular cavity is formed between the containing ring and the outer circumferential wall of the fan wheel cover; and fan blade fragments formed after the fan blades are broken under the inclusive rotating speed can break through the fan wheel cover and are contained in the containing ring cavity. The fan blade fragments can be reliably contained in the containing annular cavity, the risk that in the prior art, the fan blade fragments penetrate through a fan volute or cannot penetrate through a fan wheel cover and fly out of a ventilation face to damage external equipment is effectively prevented, and the flight safety of an airplane is guaranteed.

    本发明提供一种空气循环机及飞机空调,其中空气循环机,包括:风扇蜗壳,所述风扇蜗壳上设有风扇轮盖;风叶,组装于所述风扇轮盖内且与所述风扇轮盖同轴;包容圈,套装于所述风扇轮盖的外圆周壁外侧,所述包容圈与所述风扇轮盖的外周壁之间形成密封的包容环腔;所述风叶在包容性转速下发生断裂后形成的风叶碎片能够击穿所述风扇轮盖容置于所述包容环腔内。本发明使得风叶碎片能够被可靠地容置于包容环腔内,有效防止现有技术中的风叶碎片穿透风扇蜗壳或者不能穿透风扇轮盖而从通风面飞出损坏外部设备的风险发生,保证飞机的飞行安全。
