The invention discloses a fan cover and an engine nacelle comprising the same. The fan cover comprises a fan cover body and a pressure relief part, one end of the pressure relief part is connected to the fan cover body, at least one part of the pressure relief part is made of elastic materials, and the pressure relief part and the fan cover body are used for being arranged outside a fan casing in a covering mode. When the pressure in the fan cover rises to a preset threshold value, the pressure relief part deforms, and at least one part of the pressure relief part expands outwards in the radial direction to form an exhaust passage, so that air in the fan cover is exhausted outwards through the exhaust passage. According to the scheme, the pressure relief function under the pipeline blasting working condition is achieved through deformation of the fan cover, a pressure relief door does not need to be arranged on the fan cover, and the weight and cost of the nacelle fan cover are greatly reduced; and the risk that pressure cannot be released in time under the pipeline blasting working condition is reduced, and the difficulty of fireproof design of the fan cabin is also reduced.

    本发明公开了一种风扇罩及包含其的发动机短舱。所述风扇罩包括风扇罩本体和泄压部,所述泄压部的一端连接于所述风扇罩本体,所述泄压部的至少一部分由弹性材料构成,所述泄压部与所述风扇罩本体用于罩设于风扇机匣的外部;其中,当所述风扇罩内部的压力升高至预设的阈值时,所述泄压部产生形变,所述泄压部的至少一部分沿径向向外张开形成排气通路,以使所述风扇罩内部的空气通过所述排气通路向外排出。本方案通过风扇罩自身的变形来实现管路爆破工况下的泄压功能,无需在风扇罩上设置泄压门,大大降低了短舱风扇罩的重量和成本;降低了管路爆破工况下不能及时泄压的风险,也降低了对于风扇舱防火设计的难度。
