All Bell civil helicopters are now approved to use GE Aerospace’s Rotor Analysis Diagnostic System-Next Generation (RADS-NG) for rotor track, balance, and diagnostics. This state-of-the-art system replaces GE’s RADS-Advanced Technology (RADS-AT) and Aviation Vibration Analyzer, offering a portable, cutting-edge solution for rotor performance optimization.
With over 5,000 RADS-AT units delivered, including standard use by the U.S. Army and Navy, the first RADS-NG unit was delivered in 2024 to Henley Air in South Africa. Since then, Bell has integrated the system into flight testing and pre-delivery checks, with direct customer input helping refine its capabilities. The flexible design also allows RADS-NG to support tiltrotors, coaxial rotor helicopters, and eVTOL aircraft.
“Enabling the use of RADS-NG will differentiate the Bell fleet of helicopters as a leader in cutting-edge vibration analysis,” said Van Wilson, Bell’s director of customer solutions. “The distinct advantage of performing regular, proactive vibration measurements and monitoring this data with GE Aerospace’s latest technological advancements will provide a real-time benefit in enhancing component life and passenger comfort.”
Operators are already seeing measurable improvements. “One of our first operators reported a 10% torque savings after using RADS-NG,” said Matt Burns, GE Aerospace’s general manager of avionics.
With its ability to reduce maintenance costs, extend component lifespan, and improve passenger experience, RADS-NG is set to become a game-changer in helicopter diagnostics and performance monitoring.
