Rotary Engine Rotor Recess Geometry for Multi-Fuel Combustion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotary engines face challenges in accommodating different fuel types, particularly sustainable aviation fuels (SAFs) due to their non-standardized compositions, which affect combustion performance and efficiency.
Innovation Solution
A rotary engine rotor design with customizable recess configurations, either integrally formed or selectively attachable recess members, optimized for specific fuel types, allowing for universal compatibility and performance optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rotor uses a fixed recess geometry optimized for conventional aviation fuels, then combustion performance is optimized for standardized fuels, but combustion performance deteriorates when using non-standardized sustainable aviation fuels
Solution Approach 1:
The rotor is segmented into a base rotor body and interchangeable recess members. The recess members are separate components that can be attached to or removed from the rotor body, allowing different recess geometries to be swapped depending on the fuel type being used. This segmentation enables the system to maintain optimized combustion performance across different fuel types without requiring a completely different rotor design for each fuel.
Solution Approach 2:
The rotor system transitions from a static, fixed-geometry design to a dynamic, adjustable configuration. The ability to change recess members allows the rotor geometry to adapt dynamically to different fuel properties, optimizing combustion performance for each specific fuel type while maintaining versatility across multiple fuel options.
2Adaptability or versatility
If the rotor includes interchangeable recess members for different fuel types, then fuel type compatibility is improved, but device complexity increases
Solution Approach 1:
The base rotor body is designed as a universal component that can accommodate multiple types of recess members. The attachment mechanism and overall rotor architecture are created to work with various recess geometries, allowing a single rotor platform to serve multiple fuel types. This universality reduces the need for entirely separate rotor designs for different fuels, thereby limiting the increase in overall device complexity.
