    • The present invention relates to a propulsion unit (101) for an aircraft, including: a stationary assembly; a cowl, which is pivotable between an operating position and a maintenance position allowing access to the turbojet for regular maintenance operations and irregular maintenance operations; at least one actuator (123) secured to the stationary assembly via a main fitting (125) mounted on the stationary assembly and rigidly connected to the movable cowl; at least one safety rod (129) rigidly connected to the movable cowl and to the stationary assembly via said main fitting. The propulsion assembly according to the invention is characterised in that: the actuator (123) is sized such as to allow the cover to alternate between an operating position and a position for regular maintenance only; the safety rod (129) is sized such as to hold the cover in the position for regular maintenance only; and the main fitting (125) is sized such as to allow regular maintenance operations only. The assembly is also characterised in that it includes a secondary fitting (145) mounted on the main fitting (125), sized such as to allow irregular maintenance operations, and supporting at least said actuator (123) when the cover is in an irregular maintenance position.
    • 提供了用于飞机的推进单元。 推进单元包括固定单元,该固定单元具有至少一个枢轴安装在与推进单元的纵向轴线共线的轴上的操作位置或维护位置,以允许进入涡轮喷气发动机用于定期维护操作和不规则维护操作。 用于不规则维护操作的维护位置包括罩的打开角度,该打开角度大于罩进行定期维护操作的打开角度。 推进单元还包括至少一个汽缸和至少一个安全连接杆,所述安全连接杆固定至罩和固定单元。
