Aircraft Fuselage Section Assembly With Universal Mounting Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling aircraft fuselage sections are inefficient, as they require dedicated production units for each family of airplanes, leading to underutilization of some units and increased costs due to the need for multiple units.
Innovation Solution
A method and gear for assembling fuselage sections using a multipurpose mounting support system that allows the same production unit to assemble sections from different families of airplanes by positioning and joining panels on adjustable mounting supports, enabling the same assembly method and gear to be used across various section sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated production units are used for each family of airplanes, then assembly precision and reliability are improved, but device complexity and production costs increase
Solution Approach 1:
The mounting support is designed as a universal device that can accommodate multiple configurations for different airplane families. It includes adjustable elements and interchangeable components that allow the same production unit to assemble various fuselage section types without requiring dedicated equipment for each family, thereby reducing overall system complexity while maintaining assembly reliability
2Manufacturing precision
If multiple dedicated production units are used for different airplane families, then manufacturing precision is maintained, but productivity decreases due to underutilization
Solution Approach 1:
The mounting support incorporates dynamic and adjustable elements that allow reconfiguration between different airplane family specifications. This includes adjustable positioning mechanisms, movable components, and flexible fixtures that can be rapidly repositioned to accommodate different fuselage section dimensions and assembly requirements, enabling a single production unit to efficiently handle multiple product types without sacrificing precision
3Reliability
If multiple dedicated production units are used for different airplane families, then assembly quality is ensured, but loss of time increases due to setup changes between families
Solution Approach 1:
The mounting support is pre-configured with standardized interfaces, pre-positioned adjustment mechanisms, and pre-assembled modular components that can be quickly reconfigured for different airplane families. This preliminary preparation of the universal mounting system eliminates the need for extensive setup changes between production runs, reducing transition time while maintaining assembly quality through consistent precision features

AI summary
A method for assembling a fuselage section which comprises producing a lower part of the section from at least two panels and an upper part of the section from at least two panels, then assembling the lower and upper parts so as to obtain the fuselage section. A lower or upper mounting support, a gear and a production unit are used in the method.
