Fleet-Wide HUMS Data Aggregation and Comparative Trend Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Health and Usage Monitoring Systems (HUMS) are vendor-specific, limited to individual aircraft data, and require unique ground stations with different graphical interfaces, making it difficult for end-users to manage and analyze data across multiple aircraft types, leading to increased workload and inefficiencies in maintenance and logistics.
Innovation Solution
A web-based Health and Usage Monitoring System Service that collects, processes, and applies rule-based logic to large amounts of data, transforming it into trendable information across an entire aircraft fleet, using a common architecture and providing comparative statistics through a user-friendly web portal for proactive maintenance support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vendor-specific HUMS systems are used, then individual aircraft data can be viewed, but the system complexity increases and ease of operation decreases when managing multiple aircraft types
Solution Approach 1:
The patent implements a universal ground station that can interface with multiple HUMS vendors and aircraft types through a common architecture. The system provides a single unified interface that aggregates data from various sources (ACE, EADS, Honeywell, etc.) and presents it through consistent graphical interfaces, eliminating the need for separate vendor-specific ground stations for each aircraft type.
Solution Approach 2:
The patent introduces a data aggregation and normalization layer that acts as an intermediary between diverse HUMS systems and the user interface. This intermediate layer translates different vendor-specific data formats into a common standardized format, allowing the single ground station to communicate with multiple HUMS systems without requiring direct integration of each vendor's proprietary interface.
2Productivity
If conventional HUMS systems are used, then individual aircraft data can be collected, but the workload increases when analyzing data across the entire fleet
Solution Approach 1:
The patent segments the fleet data analysis into multiple levels of aggregation: individual aircraft level, fleet level, and comparative statistical level. The system automatically collates data from all aircraft and presents it with comparative statistics showing how individual aircraft perform relative to the fleet average, enabling users to quickly identify outliers without manually analyzing every data point.
Solution Approach 2:
The system automatically generates and presents comparative statistics and trend analysis as feedback to users. By continuously monitoring fleet data and comparing individual aircraft performance against fleet averages and historical data, the system provides actionable insights that highlight maintenance needs without requiring manual analysis of the entire fleet dataset.
3Ease of operation
If vendor-specific ground stations are used, then data from a particular HUMS can be viewed, but the ease of operation decreases with multiple different graphical interfaces
Solution Approach 1:
The patent implements a universal ground station that can interface with multiple HUMS vendors and aircraft types through a common architecture. The system provides a single unified interface that aggregates data from various sources (ACE, EADS, Honeywell, etc.) and presents it through consistent graphical interfaces, eliminating the need for separate vendor-specific ground stations for each aircraft type.
Data Source
AI summary
A Health and Usage Monitoring System (HUMS) utilizes a common architecture which permits OEM and rotorcraft operators to view and trend HUMS data for an entire aircraft fleet independent of aircraft model, HUMS vendor, or raw data format. The system operates through a web portal that provides users with comparative information on HUMS parameters relative to fleet statistics. The user may view HUMS data for the entire fleet or drill down to a particular HUMS acquisition on a specific flight. The web based format also facilities display and communication of warnings in a timely manner.
