Aeroengine Washing Fluid Collection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current washing systems for aeroengines face challenges in efficiently collecting washing fluid that seeps through the nacelle and from the engine's inlet during and after washing, particularly due to varying engine sizes and positions, leading to contamination and environmental concerns.
Innovation Solution
A mobile washing liquid collection system comprising a collection tray and an extendable inlet collector connected to the engine's inlet, featuring a flexible or rigid sheet material with anchoring and tensioning mechanisms to accommodate different engine sizes and positions, ensuring comprehensive fluid collection and easy transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed collection system is used, then the structure is simple, but it cannot accommodate different engine sizes and positions
Solution Approach 1:
The inlet collector is designed as an extendable component that can dynamically adjust its length to accommodate different engine positions and sizes. The collection tray is also designed to be movable rather than fixed, allowing the system to adapt to various engine configurations while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the inlet collector is made extendable to accommodate different engines, then adaptability improves, but the device complexity increases
Solution Approach 1:
The inlet collector is divided into multiple segments or sections that can be extended or reconfigured independently. This segmentation allows the system to achieve adaptability through modular adjustments rather than requiring a complex overall restructuring, simplifying the extendable mechanism while maintaining versatility.
3Object-affected harmful factors
If washing fluid is not fully collected, then the system is simpler, but contamination and environmental impact increase
Solution Approach 1:
The inlet collector and collection tray are merged into an integrated system where the inlet collector channels washing fluid directly into the collection tray. This combination ensures comprehensive fluid capture without requiring separate complex collection mechanisms, reducing system complexity while preventing contamination.

AI summary
The present invention is a collector (56) for collecting washing fluid issuing (40, 41) from a gas turbine engine (10) during and/or after a washing operation. The collector (56) comprises a collection tray (58, 53) and an inlet collector (70) attached at a first end (72) to the collection tray (58, 53). The second end (74) of the inlet collector (70) is connected to an inlet (12) of the engine (10), thereby collecting washing fluid (40, 41) issuing from any one or both the inlet (21) and below the engine (10).
