The efficient low-resistance air inlet device comprises a power section and an air inlet device body, the air inlet device body is located on the upper side of the power section to capture airflow, the air inlet device body comprises an air inlet section, a flow stabilizing section and an inner channel resistance reducing plate, the air inlet section is located on the upper side of the power section, and the flow stabilizing section is located on the upper side of the inner channel resistance reducing plate. The air flow is efficiently captured and decelerated through the air inlet section, and then the flow direction of the air flow is ensured to meet the working condition of the ducted fan through the flow stabilizing section; standing vortexes are generated on the rear side of the inner channel anti-drag plate to form a pneumatic wall surface to reduce a turning angle of airflow at a rear lip of the air inlet device, so that excessive overflow resistance caused by flow separation at the turning angle is avoided, and the air inlet device is ensured to be compact in structure; efficient air intake of the ducted fan in various states from vertical take-off and landing to horizontal flight can be ensured without any movable part, the oil consumption of a power system can be effectively reduced, and the voyage and the load of the aircraft can be increased.

    本发明公开了一种用于垂直起降飞行器的高效低阻进气装置,包括动力段以及进气装置,所述进气装置位于所述动力段上侧以实现对气流的捕获,所述进气装置包括进气段、稳流段以及内通道减阻板,所述进气段位于所述动力段上侧,且通过进气段实现对气流的高效捕获并对其减速,随后通过稳流段保证气流的流向满足涵道风扇的工作条件,通过内通道减阻板后侧生成驻涡以形成气动壁面来减小气流在进气装置后唇口处的转折角以避免此处出现流动分离而导致过大的溢流阻力,保证进气装置结构紧凑,且不用任何可动部件即可保证从垂直起降到水平飞行各状态下涵道风扇高效的进气,可有效降低动力系统的油耗并增大飞行器的航程及载重。
