Aircraft Component Phase Position Monitoring via Multi-Sensor Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft component monitoring systems face limitations in analyzing the health and condition of rotating machinery with variable rotation speeds, as they rely on asynchronous analytical techniques and are restricted to a single fixed location, making it difficult to accurately determine phase position and detect faults.
Innovation Solution
A computer-implemented method and system that uses data acquisition systems to receive and process signals from aircraft components, identifying phase reference points and generating models to determine the phase position of components at any given time, enabling synchronous analysis and fault detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are fitted to provide information about machinery health and status, then information about component condition is obtained, but the information is limited to a single fixed location and cannot accurately determine phase position for rotating machinery with variable speeds
Solution Approach 1:
The patent segments the monitoring approach by using multiple sensors positioned at different locations around the rotating component, rather than relying on a single sensor. This segmentation allows for comprehensive phase position determination across the entire rotation cycle, capturing information that would be missed by a single fixed-location sensor.
Solution Approach 2:
The patent transitions from single-point monitoring to multi-point spatial monitoring by distributing sensors around the rotating component. This adds a spatial dimension to the monitoring system, enabling phase position determination through comparison of signals from multiple locations rather than relying on a single fixed position.
2Adaptability or versatility
If asynchronous analytical techniques are used for machinery analysis, then analysis can be performed with limited data, but the analysis is limited and cannot effectively handle variable rotation speeds
Solution Approach 1:
The patent implements a dynamic analysis approach that adapts to variable rotation speeds by using phase-synchronized monitoring. The system dynamically adjusts its analysis based on the actual phase position of rotating components at any given moment, rather than relying on fixed-time intervals. This dynamic phase-position-based analysis maintains reliability across varying speeds by continuously synchronizing measurements with the actual mechanical phase.
3Reliability
If a single sensor location is used for monitoring, then the system complexity is reduced, but the ability to detect faults and determine phase position is compromised
Solution Approach 1:
The patent makes the monitoring system multi-functional by using the same distributed sensor array for multiple purposes: phase position determination, fault detection, and performance monitoring. The phase reference points derived from multiple sensor locations serve universal functions across different analysis types, reducing the need for separate specialized systems while maintaining high reliability.
