Lifting Rotating Mechanism for Multi-Piece Erosion Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind tunnel testing systems for thermal barrier coatings in aeroengines are expensive and limited in their ability to test multiple types of test pieces simultaneously, requiring manual adjustment of the erosion spray gun and test piece positions.
Innovation Solution
The ultrahigh-temperature wind tunnel erosion testing system incorporates a lifting and rotating mechanism with a high-speed erosion spray gun, allowing for automatic adjustment of the spray gun angle and relative position to test pieces, enabling simultaneous testing of multiple groups of test pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional testing device is used, then one type of test piece can be tested, but multiple types of test pieces cannot be tested simultaneously
Solution Approach 1:
The erosion spray gun is mounted on a lifting and rotating mechanism that enables it to test multiple types of test pieces (blade test pieces, disk test pieces, and other rotationally symmetric test pieces) with a single device configuration, achieving multi-functionality without requiring separate testing equipment for each test piece type
2Ease of operation
If manual adjustment of spray gun and test piece positions is used, then operation is simple, but adjustment efficiency is low
Solution Approach 1:
The lifting and rotating mechanism transforms the static positioning system into a dynamic one, where the erosion spray gun can be automatically adjusted to different angles and positions through lifting and rotating motions, significantly improving adjustment efficiency while maintaining operational simplicity
