Ultra-large type stretch-draw integral keel structure integration tool and method thereof

Abstract

The invention discloses an ultra-large type stretch-draw integral keel structure integration tool and a method thereof, which relate to the technical field of aircraft structure general assembly. The ultra-large type stretch-draw integral keel structure integration tool is characterized by comprising a plurality of bearing frames, a plurality of center core supports, a tail cone support, a head cone support, a plurality of center core trusses, a plurality of stiffening rings and a plurality of longitudinal pull rods, wherein the bearing frames are anchored on the ground, and the center core support, the tail cone support and the head cone support are installed on the tops of the different bearing frames respectively. Scattered multi-point support is realized by adopting a modular, segmental frame and functional support integration tool, the support has three-dimensional pose adjustment capability, and efficient, economical, rapid and simple final assembly and integration of a large-scale tensegrity keel structure are realized by utilizing self-bearing support of the central core truss and the stiffening rings; the problems of high-altitude assembly of the all-round scaffold and high cost, long period and the like caused by manufacturing, erecting, disassembling and process interference of a large number of scaffolds are solved.

Description

technical field [0001] The invention relates to the technical field of aircraft structural assembly, in particular to a super-large tension integral keel structure integration tooling and a method thereof. Background technique [0002] Stratospheric airships rely on buoyancy, propulsion and control to achieve long-term flight, fixed-point cruise, and altitude maintenance, thereby completing applications such as scientific detection and communication, and have broad application prospects. However, due to the environment such as the low density of the stratosphere and the current structural materials, energy and other technologies, the length of the airships involved in the domestic and foreign demonstrations are all more than 100m, and the commercial-grade load scenarios can be completed. The temperature alternation between day and night brings great changes in the buoyancy and pressure of the soft capsule structure, and there are challenges in maintaining the altitude of the...

AI Technical Summary

Problems solved by technology

For the airship lightweight keel system with a length greater than 100 meters and a height greater than 40 meters, due to its special structural form and characteristics, its final assembly integration method is difficult to follow the traditional rigid airship structure, aircraft cabin and other general assembly ideas
