page 2 Introduction Partners Project Background Project Achievements Conclusion
page 3 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)
page 4 Project Overview Aims -Develop a ‘next generation RTB algorithm’ -Embed human expertise within Helitune’s products Scope -3 year project -2 associates
page 5 Why do we need vibration reduction?
page 6 Business Case RTB is essential maintenance Accounts for 5-12% of all flight hours Effects of vibration costs hours of maintenance per flight hour Reducing flights quickly generates large cost savings for operators
page 7 An RTB primer Series of test flights to collect vibration data Adjust the rotor in between flights (not in-flight!)
page 8 History/Development Early Manual Methods -Flag tracking Electronic Methods -Digital Signal Processing Next Generation -Solve track & balance simultaneously
page 9 Achievements to Date Successful flight trial at RUAG in Germany
page 10 Achievements to Date CH53 implementation UH-60 Wind Tunnel Trial A109 LUH remote trials
page 11 Achievements to Date Wind Turbine Tracking UH-1D Concept Study AW101 Merlin – Onboard system
page 12 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’ -2 nd KTP established
