The invention discloses a nacelle air inlet channel, belongs to the field of airplane structure design, and particularly relates to a nacelle air inlet channel which is used for solving the problems that in the prior art, a nacelle structure is large in resistance, the lip wall of the air inlet channel is too thick, the structural efficiency is low, and the anti-icing space is large. A traditional nacelle air inlet lip and an outer wall plate are designed into a whole, installation of fasteners is reduced, and large-area laminar flow of the air inlet lip is achieved; meanwhile, the front partition plate of the air inlet channel is designed into a triangular section, so that the anti-collision performance of the front partition plate is improved under the condition that the weight of the front partition plate is equivalent, the structural efficiency is improved by reducing the wall thickness of the lip of the air inlet channel, in addition, the anti-icing space is reduced, and the air consumption is reduced.
本专利公开了一种短舱进气道,飞机结构设计领域,尤其涉及短舱进气道,用于解决现有技术中存在的短舱结构阻力大、进气道唇口壁偏厚,结构效率低,防冰空间大的问题。本发明通过将传统的短舱进气道唇口和外壁板设计为一个整体,减少紧固件的安装,实现进气道唇口的大面积层流;同时将进气道前隔板设计为三角截面,在前隔板重量相当的情况下,提高前隔板的抗撞性能,从而实现进气道唇口壁厚的降低来提高结构效率,此外还减少防冰空间,实现用气量的减少。
