Compressor Mount Bracket Structure for Aircraft Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mount brackets for aircraft cabin air supply systems lack sufficient strength and are unable to effectively manage the stresses encountered, which can lead to structural integrity issues.
Innovation Solution
A compressor mount bracket design featuring a mount floor perpendicular to a square side, an angled side extending at a non-parallel angle, and a flange with specific thickness ratios, providing enhanced structural support and stress distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional mount bracket design is used, then the structure is simple and easy to manufacture, but the strength and stress management are insufficient
Solution Approach 1:
The mount bracket incorporates a mount location with a first thickness and an angled side with a second thickness, where the ratio of the first thickness to the second thickness is between 1.38 and 1.63. This local variation in thickness provides enhanced strength at the critical mount location while maintaining a relatively simple overall bracket structure, resolving the contradiction between strength and complexity.
2Reliability
If the mount bracket thickness is increased to improve strength, then the structural integrity improves, but the weight and material usage increase
Solution Approach 1:
Rather than uniformly increasing the thickness of the entire mount bracket, the design applies increased thickness (first thickness) specifically at the mount location where structural integrity is most critical. The angled side has a reduced second thickness, optimizing the weight-to-strength ratio by concentrating material where it provides the most benefit.
Solution Approach 2:
The design specifies a precise ratio range (1.38 to 1.63) between the first thickness at the mount location and the second thickness at the angled side. This parameter optimization ensures sufficient structural integrity while minimizing unnecessary material usage and weight, balancing reliability and weight considerations.

AI summary
A compressor mount bracket has a mount floor extending to be perpendicular to a square side extending away from the mount floor in a first direction. A closure side extends from the mount floor in the first direction. An outer surface faces away from the square side. An angled side extends at a non-parallel angle from the square side and back over the mount floor. A mount location extends from the angled side, and further over the mount floor. The closure side extends along the angled side and the mount location. The mount location has a first thickness, and the angled side has a second thickness. A ratio of the first thickness to the second thickness is between 1.38 and 1.63. A cabin air supply system and a method of servicing a cabin air supply system are also disclosed.
