Nacelle air inlet channel

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
