The invention relates to the technical field of aero-engine air inlet mechanisms, in particular to an aero-engine air inlet mechanism capable of preventing a bird strike. The aero-engine air inlet mechanism comprises an air inlet cylinder, a protective screen plate is arranged at an opening in one side of the air inlet cylinder, an edge plate is fixedly welded to the edge of the protective screenplate, the edge plate is fixed in the inner wall of the air inlet cylinder through screws, a plurality of airflow through holes which are through left and right are formed in the surface of the protective screen plate, a plurality of connecting holes are further formed in the surface of the protective screen plate, and the plurality of connecting holes each are distributed between every two adjacent airflow through holes. According to the aero-engine air inlet mechanism capable of preventing the bird strike, an ultrasonic bird repeller and a laser box are arranged in a bird strike prevention device box, so that the function of repelling birds is achieved, and loss caused by collision between the birds and the air inlet cylinder is avoided; and a cotton filter plate and a drying box are arranged in the air inlet cylinder, the cotton filter plate can discharge dust sucked into the air inlet cylinder from a dust removal groove under the oscillation effect of power springs, the drying boxplays a role in drying fed air, and the service life of an engine is prolonged.
本发明公开了涉及航空发动机进气机构技术领域,具体为一种防止鸟撞的航空发动机进气机构,包括进气筒,进气筒的一侧开口设有防护网板,防护网板的边缘固定焊接有边缘板,边缘板通过螺钉固定在进气筒的内壁中,防护网板的表面设有若干组左右贯穿的气流通孔,防护网板的表面还设有若干组连接孔,若干组连接孔分布在相邻的气流通孔之间。本发明中防鸟撞装置箱中设有超声波驱鸟器和激光盒,对飞鸟有着驱赶作用,避免飞鸟与进气筒碰撞造成损失;本发明中进气筒中设有棉质过滤板和干燥盒,棉质过滤板通过动力弹簧的振荡作用,会将吸入进气筒中的灰尘从除尘槽中排出,而干燥盒则起到给进去的空气进行干燥的作用,增加了发动机的使用寿命。
