Embodiment Construction

[0013] Below in conjunction with accompanying drawing the present invention is described in further detail, please refer to Figure 1 to Figure 3 .

[0014] Such as figure 1 As shown, it is a general sealing structure, and its structure adopts superelastic material as the sealing plate material, which can meet the sealing requirements, but the service life is short, the reliability is low, and the material requirements are high.

[0015] Such as Figure 2-3 As shown, it is a schematic diagram of the structure of the present invention, a passive follow-up sealing structure, including a fixed airfoil joint 1, a rudder surface joint 2, a fixed airfoil joint support 3, a rudder surface joint support 4, a connecting rod 5, Connecting rod 6, sealing plate support 7, sealing plate 8, skin on fixed wing surface 9, lower skin on fixed wing surface 11, skin on rudder surface 12, lower skin on rudder surface 14, the sealing structure It also includes a fixed airfoil main structure 10 ...

Abstract

The invention provides a passive follow-up sealing structure. The passive follow-up sealing structure comprises a fixed wing surface connector 1, a control surface connector 2, a fixed wing surface connector support 3, a control surface connector support 4, a connecting rod 5, a connecting rod 6, a sealing plate support 7, a sealing plate 8, a fixed wing surface upper covering skin 9, a fixed wingsurface lower covering skin 11, a control surface upper covering skin 12, a control surface lower covering skin 14, a fixed wing surface main structure 10 and a control surface main structure 13. Byadopting the passive follow-up sealing structure provided by the invention, the passive follow-up sealing structure follows deflection when the deflection is realized by a control surface; on one hand, the requirement on airflow continuity at any time can be met, and a better sealing effect is kept; on the other hand, the strict requirement of the passive follow-up sealing structure on material rigidity is weakened, the reliability of the passive follow-up sealing structure is improved, and the service life of the passive follow-up sealing structure is prolonged.

Description

technical field [0001] The invention is a passive follow-up sealing structure, which is used to realize the sealing requirements of the combination of aircraft rudder surface structure and fixed wing surface structure, and is suitable for aircraft flaps, ailerons, rudders and the like. Background technique [0002] The sealing structure of the aircraft is a structure that installs and fixes the combination of the wing surface structure and the rudder surface structure. The main purpose is to ensure the continuity of the airflow. It is widely used in various fighter jets at home and abroad. Due to the complex stress on this part, the impact on stealth involves multiple disciplines such as static strength, aeroelasticity, flutter and fatigue. At present, the sealing structure of the aircraft is generally a sealing plate with a cantilever structure installed on the fixed wing surface. This kind of sealing structure has poor rigidity, is easy to be damaged, has poor sealing eff...
