The invention relates to a propulsion system comprising a chassis (402), a fan cowl (208), an articulation system (300) fixed between the chassis (402) and the fan cowl (206), and comprising a shaft (302) having two offset cylinders wherein the central cylinder is movably rotatably mounted on the chassis (402), and wherein the central cylinder is rotatably mounted on the chassis (402), and wherein the fan cowl (208) is rotatably mounted on the chassis (402). The fan cowl (208) comprises a central cylinder (402), a lateral cylinder (208) movably rotatably mounted on the fan cowl (208), a blocking device (406) restricting rotation of the central cylinder relative to the chassis (402) between a closed position and an intermediate position, and a stop device (406) allowing rotation of the fan cowl (208) between the intermediate position and an open position and preventing rotation of the fan cowl (208) beyond the intermediate position. In such an arrangement, the fan cowl moves laterally when it begins to open, which reduces the risk of interaction.

    本发明涉及一种推进系统,其包括底架(402)、风扇整流罩(208)、铰接系统(300),铰接系统固定在底架(402)与风扇整流罩(206)之间,并且包括轴(302)、阻挡装置(306)和止动装置(308),轴具有两个偏移的圆柱体,其中,中心圆柱体可动地旋转安装在底架(402)上,并且其中,侧向圆柱体可动地旋转安装在风扇整流罩(208)上,阻挡装置将中心圆柱体相对于底架(402)的旋转限制在关闭位置与中间位置之间,止动装置允许风扇整流罩(208)在中间位置与打开位置之间旋转,并防止风扇整流罩(208)旋转超过中间位置。以此类布置,风扇整流罩在其开始打开时侧向运动,这减小了相互作用的风险。
