Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional jet engine maintenance schedules do not consider the actual performance and condition of the engine when determining wash events, leading to inefficient cleaning and potential engine deterioration.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fixed maintenance schedules are used for engine washes, then maintenance operations can be performed regularly, but cleaning efficiency decreases and engine life is not maximized
Solution Approach 1:
The patent transitions from static fixed-schedule maintenance to dynamic condition-based maintenance. The system continuously monitors engine parameters (vibration, temperature, pressure, flow rate) and adjusts wash timing based on actual contamination levels and performance degradation, allowing maintenance operations to adapt to real-time engine conditions rather than following a predetermined schedule
Solution Approach 2:
The system implements closed-loop feedback by monitoring engine performance parameters, comparing them against baseline values, detecting degradation trends, and triggering wash operations when specific thresholds are exceeded. This feedback mechanism ensures washes are performed based on actual need rather than arbitrary time intervals, optimizing both cleaning efficiency and engine life extension
2Reliability
If engine washes are performed frequently, then engine cleanliness is maintained, but maintenance costs increase
Solution Approach 1:
The system monitors multiple engine parameters (vibration frequency, temperature differential, pressure drop, flow rate changes) to detect contamination accumulation. By tracking changes in these parameters over time and comparing them to baseline values, the system determines the optimal wash timing based on actual contamination levels rather than performing washes at fixed intervals, thereby reducing unnecessary maintenance costs while maintaining engine cleanliness
3Loss of substance
If engine washes are delayed, then maintenance costs are reduced, but engine performance deteriorates
Solution Approach 1:
The system continuously monitors engine performance parameters and compares them against baseline values to detect degradation trends. When parameter changes exceed predetermined thresholds indicating significant contamination accumulation, the system triggers a wash operation. This feedback mechanism ensures washes are delayed only as long as performance allows, preventing excessive deterioration while avoiding premature washes that would increase costs
