Aircraft Fleet Health Monitoring with Anomaly Detection Techniques

Anomaly Detection in Aircraft Gas Turbine Engines

Challenges and Opportunties in Taxi Fleet Anomaly Detection

To enhance fleet operation and management, taxi operators instrument their vehicles with GPS receivers and network connectivity to servers. Mobility traces from such large fleets provide significant information on commuter travel patterns, traffic congestion and road anomalies, and hence several researchers have mined such datasets to gain useful urban insights. The fleet companies, however, in...

Aircraft Electrical Monitoring & Fault Detection

Fault detection and electrical system monitoring (management) for aircraft/spacecraft dc or 400 Hz electrical systems is presented. Real-time ‘snapshot’ data is collected from current and voltage measurement transducers on radial or loop aircraft electrical system and introduced into a State Estimator. The State Estimator ‘smoothes’ the data, detects bad transducers, and calculates the best est...

Unsupervised Anomaly Detection for Liquid-Fueled Rocket Propulsion Health Monitoring

This article describes the results of applying four unsupervised anomaly detection algorithms to data from two rocket propulsion testbeds. The first testbed uses historical data from the Space Shuttle Main Engine. The second testbed uses data from an experimental rocket engine test stand located at NASA Stennis Space Center. The article describes nine anomalies detected by the four algorithms. ...

IDS: Improving Aircraft Fleet Maintenance

This paper describes the Integrated Diagnostic System (IDS), an applied AI project concerned with the development of hybrid information systems to diagnose problems and help manage repair processes of commercial aircraft fleets. A study at one major airline indicated that significant benefits could accrue (approximately 2% of overall maintenance budget) through the use of innovative information...
