Problems solved by technology

[0003] The existing airborne antenna is an exposed copper cable antenna, which has the following disadvantages: the length of the antenna is long, and the copper cable antenna is exposed outside the fuselage. It is easily affected by wind, rain, salt spray, etc. when performing special tasks in special areas, which will accelerate the environmental corrosion of the equipment and cause Broken wires of copper cables, wear or even breakag

Embodiment Construction

[0022] Such as image 3 As shown, on the basis of ensuring the original aerodynamic configuration, the dorsal fin is divided into upper and lower cabins. The lower cabin is composed of a detachable support plate 1 and multiple ribs 5 below it, and has side skins on the outside. The armrest box 2 for maintenance is housed on the skin, and the mission system antenna 4 and the reflector 3 are fixedly installed on the rib plate 5 .

[0023] Such as Figure 4 As shown, the upper cabin is composed of a plurality of brackets 7 installed on the detachable support plate 1, and has a dorsal fin skin on the outside, and the carrier antenna 6 is supported and fixed by the plurality of brackets 7 and covered by the dorsal fin skin.

[0024] The upper surface of the upper cabin is about 5648mm long, the lower surface is about 5539mm long, and the height direction is about 300mm; the lower cabin can be regarded as a triangle with a bottom length of about 5393mm, a hypotenuse length of about...

Abstract

The invention belongs to the field of aircraft overall aerodynamic integrated layout design, and particularly relates to a dorsal fin aerial carrier and task system antenna integrated configuration. An existing aerial carrier antenna is an exposed copper cable antenna which is long in length, the copper cable antenna is exposed outside a fuselage and is likely to be affected by wind, rain, salt fog and the like when special tasks are executed in a special area, environmental corrosion of equipment is accelerated, consequently, a copper cable is broken, an antenna support pulley and a steel cable are abraded and even broken, and reliability is low. According to the dorsal fin aerial carrier and task system antenna integrated configuration, by designing an environment-friendly antenna mounting cabin, an aerial carrier antenna and a task system antenna are mounted and arranged in a fuselage structure, and the original aerodynamic characteristic of an aircraft is not affected negatively tothe maximum limit.

Description

technical field [0001] The invention belongs to the field of overall aerodynamic comprehensive layout design of an aircraft, and in particular relates to an integrated configuration of a dorsal fin carrier aircraft and a mission system antenna. Background technique [0002] According to the requirements of the whole aircraft antenna layout, mission performance and electromagnetic compatibility design of the whole aircraft, it is necessary to install mission system antennas with small antenna diameters, high field of view and maintainability requirements on the aircraft; figure 1 As shown, the aircraft antenna is in the form of a copper cable antenna. There are two antennas in one type. [0003] The existing airborne antenna is an exposed copper cable antenna, which has the following disadvantages: the length of the antenna is long, the copper cable antenna is exposed outside the fuselage, and it is easily affected by wind, rain, salt and fog when performing special tasks in ...
