Composite-Covered Turbine Engine Component for Stress Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Turbine engine components made of composite materials face challenges in withstanding mechanical stresses and external forces during operation, particularly at high temperatures and due to rotational dynamics, leading to potential damage.
Innovation Solution
A composite structure is reinforced with a cover structure, which can be metallic or plastic, coupled to the composite structure using methods like welding, adhesion, or integration, to enhance its strength and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If composite materials are used for turbine engine components, then weight is reduced and manufacturing flexibility is improved, but strength and durability under mechanical stress are insufficient
Solution Approach 1:
The invention applies composite materials by combining a composite structure with a cover structure (metallic or plastic) to create a hybrid component that leverages the weight advantages of composites while gaining the strength and durability of traditional materials. The cover structure encapsulates the composite structure, creating a composite-of-composites solution that resolves the strength deficiency of pure composite materials.
2Ease of manufacture
If composite materials are used for turbine engine components, then ease of manufacture is improved, but reliability under operational forces is insufficient
Solution Approach 1:
The invention creates a composite structure where a composite component is encapsulated by a cover structure made of metallic or plastic material. This hybrid composite approach maintains the manufacturing flexibility of composite materials while incorporating the reliability and durability of traditional materials, thereby improving operational reliability without sacrificing ease of manufacture.
3Strength
If a cover structure is added to reinforce the composite structure, then strength and durability are improved, but device complexity increases
Solution Approach 1:
The invention merges the composite structure and cover structure into a unified hybrid component where the cover structure encapsulates the composite structure. This integration approach combines multiple materials and structures into a single functional unit, improving strength and durability while minimizing the increase in device complexity through unified design and assembly.
