Embodiment Construction

[0026] The present invention is described in detail below in conjunction with accompanying drawing of description:

[0027] When docking, use the fuselage as the standard, fix the fuselage with brackets, and let the wings dock on the fuselage. figure 1 It is a typical butt joint structure of the fork ear fuselage and wing of a typical small aircraft. Taking the right side as an example, from front to back, it is the intersection point 1 of the first docking frame, the intersection point 2 of the second docking frame, the intersection point 3 of the third docking frame, and the intersection point 3 of the third docking frame. 4. Intersection point 4 of the docking frame, intersection point 5 of the fifth docking frame, except that the intersection point of the first docking frame is a single intersection point, and the rest of the docking frames are both upper and lower groups of docking intersection points. by figure 1 For example, the docking process and requirements are as ...

Abstract

The invention relates to a method for fast manual docking of fuselage wings, belonging to the field of manual fast docking methods for fuselage wings of small aircraft with a fork ear type fuselage wing docking structure. The present invention selects the docking reference, fork-ear type docking structure, with the fuselage as the standard for docking the wing, and its docking reference is composed of upper and lower references, front and rear references, and left and right references; the upper and lower references select the upper ear piece joint hole with the largest distance as the docking reference. Positioning; the front and rear reference position degrees of freedom are positioned based on the end face of the middle lower joint ear piece; the left and right reference position degrees of freedom are positioned based on the middle lower joint ear piece hole as a reference; solve multi-intersection, high-precision, non-compensated fuselage wing docking When the small aircraft of the structure do not have advanced docking technology equipment and means in the field of troops and in wartime, it can realize fast and manual docking, realize rapid maintenance and overhaul, improve the maintainability of fighters in the field, and improve the performance of fighters in extremely unfavorable conditions in wartime. survival and combat capabilities.

Description

technical field [0001] The invention relates to a method for fast manual docking of fuselage wings, which belongs to the field of manual rapid docking methods for small aircraft fuselage wings with a fork ear type fuselage wing docking structure. Background technique [0002] Fighters of the third generation and above require high maneuverability and high structural strength. In addition to high aerodynamic shape requirements, the aircraft must also strictly control the structural weight. Therefore, many designs use fork-ear fuselage-wing docking structures. Due to the difference in aircraft speed, overload, and aerodynamic layout, the butt joints of the ear-fork fuselage and wings of small fighters are generally arranged on 4-5 load-bearing frames, and there are about 7-9 sets of joints, which have the characteristics of many docking points; Most of the docking intersection points of each group are matched with E9 (joint hole of fuselage) / f9 (butt bolt) / H8 (joint hole of wi...
