The invention relates to aviation, namely to air intakes of gas-turbine power plants of aircraft. An inlet device of low-resistance, in-depth type is intended for intake of external air and its supply it to an engine and other consumers. The technical object of the invention is improvement of parameters, increase of stability factor of a power plant, extension of application field of the inlet device type of in-depth type. The inlet device type of in-depth type comprises a curved guiding tray smoothly connected by large radii of rounding and made flush with the surface of an aircraft, a short curved air duct, a collector, an annular outlet, which is connected through an annular slit with the engine compartment and designed to remove a boundary layer and supply of cooling air to the engine. The upper surface of the duct together with the surface of aircraft forms an upper lip. |
