Health and Usage Monitoring System
NASA, the US Navy, and numerous other organizations and governments around the world are using the Health and Usage Monitoring System (HUMS) software developed by Foliage. HUMS is designed to monitor virtually all aspects of an aircraft in flight and can be used on both fixed wing and rotary aircraft. This system employs sensors to collect, store, and analyze critical flight data. HUMS warns pilots in real time of possible in-flight problems.
a. Onboard Aircraft Monitoring System
Foliage developed a system to monitor and analyze data during flight, which is collected from up to 200 different sensors of varying types. The system communicates with other avionics systems though various interfaces including ARINC-429, RS-422, as well as analog, digital, pulse, synchro, and parallel interfaces. The software is designed to be configurable to perform on a wide variety of aircraft types. The onboard system performs in-flight, predictive failure analysis based on its unique vibration signature.
The system was developed for real-time kernel in C++ and was developed using DO178B Level C.
b. Aircraft Fleet Management System
Foliage created a distributed fleet management system for aircraft operators. The software operates over a distributed geographical area and provides detailed assembly and part tracking, maintenance management, aircraft usage analysis, and report generation. The system provides a graphical environment for managing and tracking the exact configuration and usage conditions of every aircraft in the fleet. Upon landing, usage data is downloaded into a ground-based system through a PCMCIA cartridge. The ground-based software determines if usage conditions from the flight should keep the aircraft grounded for inspection, overhaul or maintenance. The data is aggregated nightly into a central ground-based system which tracks every part on each aircraft in the fleet and issues and tracks maintenance directives. The system also provides powerful analysis and correlation tools to perform predictive failure analysis, historical reporting, and fleet-wide troubleshooting. Moreover, the ground-based system provides an interactive flight-playback capability that graphically scrolls any of several hundred parameters collected while in flight.
The system was developed on Sun O/S and Windows 3.1 in C++.
