Abstract

The invention relates to an integrated aircraft fuselage with a skin antenna, and belongs to the field of radar platform load integrated design. The aircraft fuselage comprises a left fuselage side wall mechanism, a right fuselage side wall mechanism, a fuselage top wall plate and a fuselage bottom wall plate; the two sidefuselage mechanisms have the same structure; each fuselage side wall mechanism is formed by transversely arranging and connecting a plurality of machine body side wall units; and each fuselage side wall unit comprises a fuselage frame composed of a pair of rod-shaped fuselage frame edges, an upper truss girder and a lower truss girder, a fuselage outer mask is arranged on the outer side face of the fuselage frame, two antenna unit sets are evenly distributed on the inner side face of the fuselage frame, and each antenna unit set comprises three or more antenna units. An integrated skin antenna array surface conformal with the fuselage is formed; and the plurality of antenna unit groups are electrically connected through connecting ribs, upper trussed beams and lower trussed beams to form an antenna array plane. The antenna array plane does not need extra supporting structures such as a hanging bin, a disc and a balance beam, and the load weight can be reduced by about 12%.

Description

technical field

[0001] The invention belongs to the field of radar platform load integration design, and in particular relates to an aircraft fuselage with an integrated design of aircraft fuselage skin and radar antenna structure, which is mainly used in sensor aircraft or platform load integrated aircraft platforms. Background technique

[0002] As an important part of electronic equipment, the antenna array is usually composed of a large number of antenna elements in a certain array, which mainly emits and receives various electromagnetic waves. Now all kinds of airborne detection, communication, and surveying and mapping electronic equipment contain a large number of antenna arrays.

[0003] In traditional airborne electronic equipment, these antenna arrays are usually installed on the nose of the aircraft, inside the fuselage, or suspended at the bottom of the belly in the form of a pod, or installed on the back of the fuselage in the form of a disc or balance beam. . ...
