Problems solved by technology

The gaps on the surface of the aircraft will produce surface electromagnetic defects, and the scattering cannot be eliminated. The suppression effect of the sub-weak scattering source caused by surface electromagnetic defects such as aircraft gaps is poor, and the electromagnetic continuity problem on the aircraft surface cannot be satisfied.

Abstract

The invention belongs to the technical field of scattering inhibition, and particularly relates to a covering cap capable of suppressing gap scattering. A first gap chamfer is arranged on the side face, close to a skin (2), of a covering cap (1), a second gap chamfer is arranged on the side face, close to the covering cap (1), of the skin (2), a gap is formed between the first gap chamfer and thesecond gap chamfer, and the gap is filled with a sealant (3); and a conductive paint (4) is arranged at the joint of the outer surfaces of the covering cap (1) and the skin (2). According to the technical scheme, electromagnetic scattering caused by the gap of the covering cap of an airplane can be effectively restrained, secondary scattering RCS is reduced, and the covering cap has important significance in improving the comprehensive stealth performance of the airplane.

Description

Technical field[0001]The present application belongs to the field of scattering suppression, and in particular, to a mouth cover capable of suppressing a slit scatter.Background technique[0002]In order to ensure the use and maintenance of the aircraft, a large number of mouths were opened in the surface of the aircraft, thus affecting the continuity of the surface skin of the aircraft, and the surface quality of the aircraft has an important impact on the stealth performance of the whole machine. With the improvement of stealth performance, the aircraft causes harmful electromagnetic scatter due to design, manufacturing aircraft surface gap, enabling the entire machine RCS, from secondary scattering source to major scattering sources, should be in design, manufacturing Control.[0003]In order to ensure the surface quality of the aircraft, according to the aircraft surface gap design control requirements, the gap of the mouth is 0.5 to 1.0 mm of the sketch and longitudinal gap require...
