Abstract

The invention relates to the technical field of aircraft design, in particular to a ram air entrainment structure. The structure comprises an air entrainment device, a plurality of air entrainment holes are arranged along the axial direction, and one end facing the outside of the machine is conformal with the fuselage; One end of the supporting device is fixedly connected with one end of the air guide structure facing the inside of the machine, and is used for supporting the air guide structure and communicating the air guide hole with the inside of the machine body. The structure is arrangedin an air inlet opening of the airframe, no protrusion is formed on the exterior of the airframe after installation, and the structure is highly integrated with the airframe so as to maintain the aerodynamic shape of the airplane, thereby reducing the flight resistance of the airplane, stabilizing the flight of the airplane, and avoiding damaging the stealth performance of the airplane to a certain extent; In addition, the structure is simple, easy to manufacture, easy to install, easy to replace the existing ramp air inlet structure design.

Description

technical field [0001] The invention relates to the technical field of aircraft design, in particular to a ram air bleed structure. Background technique [0002] Ram air comes from the air outside the aircraft and is an important heat sink in aircraft design. It is mostly introduced into the aircraft through the ram air intake installed on the fuselage or wing. According to the shape and installation position of the ram air inlet, it can be divided into: figure 1 and figure 2 Leading edge bleed and funnel bleed shown. [0003] The above-mentioned leading-edge air-inducing port and funnel-shaped air-inducing port, or opening directly on the leading edge or protruding from the aircraft skin, increase the flight resistance of the aircraft. In addition, the technical information on the stealth of the aircraft shows that it also affects the stealth performance of the aircraft to varying degrees. damage, leading to a decline in stealth performance. Contents of the invention ...
