Health Monitoring in Helicopters KTP Regional Seminar By Steve Pollard
Introduction • Partners • Project • Background • Project Achievements • Conclusion
KTP Partners • Company Partner – Helitune Ltd • Provides Aircraft Vibration Solutions for Rotor Track & Balance (RTB) • Customers in over 30 countries worldwide • Academic Partner - University of Bristol • Aerospace Engineering • Bristol University Laboratory for Advanced Dynamics Engineering (BLADE)
Project Overview • Aims • Develop a ‘next generation RTB algorithm’ • Embed human expertise within Helitune’s products • Scope • 3 year project • 2 associates
Business Case • RTB is essential maintenance • Accounts for 5-12% of all flight hours • Effects of vibration costs 2.5-3 hours of maintenance per flight hour • Reducing flights quickly generates large cost savings for operators
An RTB primer • Series of test flights to collect vibration data • Adjust the rotor in between flights (not in-flight!)
History/Development • Early Manual Methods • Flag tracking • Electronic Methods • Digital Signal Processing • Next Generation • Solve track & balance simultaneously
Achievements to Date • Successful flight trial at RUAG in Germany
Achievements to Date • CH53 implementation • UH-60 Wind Tunnel Trial • A109 LUH remote trials
Achievements to Date • UH-1D Concept Study • AW101 Merlin – Onboard system • Wind Turbine Tracking
Summary • Benefits to date • Algorithm in use • Improved predictive capability for equipment • Results show reduction in number of flights needed • KTP has won substantial business for the company • Networking opportunities for both Company and University • Looking Forward • Further algorithm development • Add ‘intelligence’ • 2nd KTP established
