Technical Field

[0001] The invention relates to the technical field of high-speed target drones, and in particular to a stealth control surface installation structure of a flying wing layout target drone. Background Art

[0002] In the military field, target drones are necessary equipment for testing the quality of weapons. They have always been in a relatively important position in radar testing and missile testing. In the testing of various target drones, the stealth performance of target drones is a key indicator of radar test target drones. In order to ensure its good stealth performance, protrusions must be reduced or avoided at the bottom of the fuselage. Among the target drones currently on the market, the target drones with flying wing layouts have good stealth performance. The resistance rudder surface of the flying wing layout plays the role of a rudder during flight. The design of the mounting structure is particularly important, which requires both structural stability and stealth. Most of the rudder actuators on the market are exposed new types, which have large reflection surfaces when doing RCS tests and do not meet the stealth requirements. Therefore, it is imperative to realize stealth rudder surfaces.
