Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft health and usage monitoring systems (HUMS) can only analyze data and provide maintenance recommendations when the aircraft is on the ground, leaving pilots without sufficient information to address hazardous conditions in-flight.
Innovation Solution
A real-time health and usage management system (RT HUMS) that collects and transmits data to a remote location during flight, allowing for in-flight analysis and transmission of flight crew-enabling information to mitigate mechanical issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If HUMS data is analyzed only when the aircraft is on the ground, then data analysis accuracy is improved, but response time to hazardous conditions deteriorates
Solution Approach 1:
The system segments the data analysis function into two parts: preliminary analysis is performed onboard the aircraft using onboard processors, while comprehensive analysis is performed on the ground using ground-based processors. This segmentation allows immediate detection and response to hazardous conditions while maintaining accurate ground-based analysis capabilities.
Solution Approach 2:
The system performs preliminary data analysis and hazard detection onboard the aircraft before the aircraft returns to ground. This preliminary action enables the system to identify hazardous conditions in real-time and provide alerts to pilots, allowing them to take remedial action before landing.
2Loss of time
If HUMS data is transmitted in real-time during flight, then response time to hazardous conditions is improved, but data transmission complexity increases
Solution Approach 1:
The system extracts only the essential data elements needed for real-time hazard detection and transmits them during flight, while leaving comprehensive data analysis for ground-based processing. This extraction approach reduces the amount of data transmitted and processed in real-time, thereby reducing transmission complexity while maintaining rapid response capability.
Solution Approach 2:
The system uses an intermediary onboard processor that pre-processes HUMS data before transmission to the ground. This intermediary performs initial filtering, aggregation, and prioritization of data, reducing the burden on ground-based systems and simplifying real-time transmission requirements.
3Loss of time
If comprehensive HUMS data is analyzed onboard the aircraft, then response time is improved, but onboard processing requirements increase
Solution Approach 1:
The system segments processing tasks between onboard and ground-based systems. Onboard processors handle time-critical functions such as real-time monitoring, hazard detection, and immediate alert generation. Ground-based processors handle comprehensive analysis, detailed diagnostics, and long-term trend analysis. This segmentation reduces onboard processing requirements while maintaining rapid response capability.
Solution Approach 2:
The system performs partial data analysis onboard the aircraft - specifically, only the critical functions needed for immediate hazard detection and response. Comprehensive analysis is left for ground-based processing. This partial action approach provides sufficient information for pilots to respond to hazardous conditions without requiring full onboard processing capability.

AI summary
A system and method for operating an aircraft. The system includes a health and usage monitoring system (HUMS) system for sensing health and usage data during flight of the aircraft, and a data transmission unit. The data transmission unit retrieves HUMS data from the HUMS system and generates a trigger signal when the retrieved HUMS data meets a selected criterion, the trigger signal being indicative of a condition of the aircraft. In response to the trigger signal, the data transmission unit transmits the retrieved HUMS data to a remote location.
