Problems solved by technology

However, for stealth aircraft, the surface of the fuselage should be smooth to reduce electromagnetic scattering characteristics. At the same time, the aircraft requires navigation lights to be installed on specific parts to indicate the position and heading of the aircraft. Therefore, the navigation light becomes an irreversible scattering source on the surface of the stealth aircraft, which affects the stealth effect of the stealth aircraft

Abstract

The invention discloses a navigation lamp fairing. The navigation lamp fairing comprises a fuselage appearance body, wherein a fairing base is arranged on the fuselage appearance body, the fairing base is provided with a fairing main body through a fairing transition section, the surface of the fairing main body is covered with a transparent conductive film, the fairing base corresponds to the shape of the fuselage appearance body, the fairing base and the fuselage appearance body are both arched, the outer side of the fairing transition section is semicircular, and the radius of the semicircle is 1-50 mm. As the fairing base and the fuselage appearance body are arched correspondingly, a low-scattering appearance is formed, the transparent conductive film covers the fairing main body, scattering signals of a navigation lamp are eliminated from the aspects of the appearance and material respectively, and radar characteristics of the navigation lamp are reduced, so that the navigation lamp has a good hiding effect on the premise of not reducing illumination intensity and illumination range.

Description

Technical field [0001] The invention belongs to the technical field of aircraft navigation lights, and particularly relates to a navigation light fairing. Background technique [0002] Navigation lights refer to the signal lights installed on the aircraft for mutual discovery of air traffic and judging the direction of flight. It is stipulated that the aircraft should be equipped with navigation lights on its two wing tips, and it is stipulated that the left wing tip is red and the right wing tip is green. It is customary to include white lights on the tail of the aircraft. Must be connected during flight. Navigation lights are used to detect each other when taxiing on the ground at night to determine the direction of taxiing, and to determine the distance to prevent wing tip collisions. The navigation lights have lampshades to protect the navigation lights. [0003] The patent number is CN201620517673.9 and the application date is 2016-05-31. It discloses a fuselage lampshade s...
