Technical Field

The invention belongs to the technical field of radars for airplanes, and particularly relates to a radome bracket with a control surface.

Background

In the existing early warning machine, a fixed bracket is usually adopted to support the radome. Although the appearance and the installation position of the bracket are both optimally designed, in the actual flight of the airplane, the side washing and blocking effects of the radome body bracket on the vertical fin reduce the vertical fin efficiency and obviously reduce the course stability of the airplane.

The existing solutions of the early warning machine include the following: the aircraft flight control system is improved, but the improvement degree is limited, and the aircraft flight control system is generally used under the condition of early warning of high course stability of an airborne aircraft body; pneumatic measures such as adding small vertical tails on ventral fins, a horizontal tail end plate and a horizontal tail are added, the weight and the pneumatic resistance of the airplane are increased, and the performance of the airplane is reduced.

(4) And certain gaps are reserved at the upper end and the lower end of the fixed support 1 respectively, so that the deflection of the front edge control surface and the rear edge control surface of the support does not interfere with other components.
