The invention provides an embedded air inlet channel suitable for a stealth patrolling device. A main implementation formula is a new center line change rule formula, the camber angle of an inlet of the air inlet channel ranges from 0 degree to 12 degrees, and the equivalent length-width ratio ranges from 2 to 3. When the embedded air inlet channel is practically applied to the design of the embedded air inlet channel of the stealth patrolling flight device, the air inlet channel which is excellent in stealth effect and has the air inlet channel aerodynamic performance reaching the standard can be obtained. The total pressure recovery coefficient is 92% or above, and the forward RCS value is reduced by 30% compared with a common air inlet channel.
本发明提供一种适用于隐身巡飞器的埋入式进气道,本发明主要实现公式为新中心线变化规律公式以及进气道入口外倾角范围在0°~12°,等效长宽比范围在2~3。本发明在实际运用于隐身巡飞器的埋入式进气道设计中,可以得到一个隐身效果优异,进气道气动性能达标的进气道。总压恢复系数在92%以上,前向RCS值与普通进气道相比降低30%。
