Integrated Fluid Conduits in Gas Turbine Casing Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wing-mounted gas turbine engines require larger nacelles to accommodate fluid routing, leading to increased aerodynamic drag and reduced aircraft performance due to size penalties.
Innovation Solution
Integration of fluid conduits directly into the engine casing, reducing the need for external conduits and nacelle size, while allowing shared walls for weight reduction and improved aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If external fluid conduits are used in the nacelle, then fluid routing functions are achieved, but the nacelle size increases leading to higher aerodynamic drag
Solution Approach 1:
The patent merges the fluid conduit structure with the engine casing by integrating the conduit into the casing wall. This consolidation eliminates the need for separate external conduits in the nacelle, reducing nacelle size and minimizing aerodynamic drag while maintaining fluid routing functionality.
2Weight of moving object
If external fluid conduits are used, then fluid routing is achieved, but weight increases due to additional components and attachment fixtures
Solution Approach 1:
The conduit is integrated into the engine casing wall, allowing the casing and conduit to share a common wall structure. This eliminates the need for separate conduit components and attachment fixtures, reducing overall weight while maintaining fluid routing capability.
3Reliability
If separate conduits are attached to the casing, then fluid routing is achieved, but vibration-induced failures occur due to attachment fixtures
Solution Approach 1:
By integrating the conduit directly into the engine casing wall as a unified structure, the patent eliminates attachment fixtures that would be susceptible to vibration-induced failures. The shared wall design creates a rigid, vibration-resistant connection between the conduit and casing.
