Aircraft Engine Mounting with Adjustable Connecting Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine coupling devices for aircraft are complex, lack precise adjustment capabilities, and often result in hyperstatic mounting systems, making them difficult to access and maintain.
Innovation Solution
The use of adjustable connecting rods and a transverse beam to securely attach the front aerodynamic structure to the rigid structure, allowing for precise positioning and forming an isostatic mounting system with a fail-safe mechanism, ensuring efficient force absorption and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complex hooking means are used to mount the front aerodynamic structure on the rigid structure, then the mounting system provides structural support, but the device complexity increases and accessibility deteriorates
Solution Approach 1:
The mounting system is segmented into distinct functional elements: the rigid structure, the front aerodynamic structure, and simple hooking means. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining structural support capability.
Solution Approach 2:
The complex attachment mechanisms are extracted and replaced with simple hooking means. The essential mounting function is retained while removing unnecessary complexity, improving accessibility and ease of maintenance.
2Strength
If complex hooking means are used to mount the front aerodynamic structure, then structural support is provided, but ease of operation deteriorates
Solution Approach 1:
By segmenting the mounting system into separable components with simple hooking means, operators can easily access and maintain the front aerodynamic structure without dealing with complex attachment mechanisms, improving ease of operation.
3Strength
If traditional attachment means are used, then the front aerodynamic structure is mounted on the rigid structure, but positioning precision deteriorates
Solution Approach 1:
The hooking means are designed to allow dynamic adjustment of the front aerodynamic structure's position relative to the rigid structure. This enables precise positioning while maintaining secure mounting, resolving the contradiction between mounting capability and positioning precision.
