Bell Textron, Inc., a Textron Inc. company, has approved the use of the Rotor Analysis Diagnostic System Next Generation (RADS-NG) across its commercial helicopter fleet, including the Bell 505, Bell 429, Bell 412, and Bell 407 models. This cutting-edge system, developed by GE Aerospace, enhances vibration monitoring capabilities and introduces significant operational benefits for operators.
RADS-NG allows for proactive and precise measurement of vibrations, enabling operators to track component performance and identify potential issues before they escalate into costly maintenance problems. By supporting more efficient rotor track and balance operations, the system helps reduce the number of flights required for diagnostics, saving both flight time and fuel. Some operators have already reported tangible benefits, including a 10% torque saving, which highlights the potential for reducing wear on components and improving overall aircraft efficiency.
Designed with flexibility in mind, RADS-NG accommodates future aircraft concepts such as tilt rotors, co-axial rotors, and electric vertical take-off and landing (eVTOL) platforms. It replaces the previous RADS-AT and AVA systems, becoming GE Aerospace’s standard portable solution for Rotor Track and Balance (RT&B), particularly where permanent installations are not feasible or where supplemental analysis is needed.
The system has already been delivered to Henley Air, who operate a mixed fleet that includes Bell helicopters. GE Aerospace provided full training and support, ensuring seamless implementation. RADS-NG has also been deployed at Bell facilities to support flight testing and pre-delivery inspections.
With over 30 years of experience in vibration diagnostics, RADS-NG continues to build on GE Aerospace’s reputation for reliability. As the established RT&B standard used by the US Army and the UK Navy, the system serves both rotary and fixed-wing aircraft, including the Lockheed C-130 Hercules, while also preparing to support the next generation of eVTOL aircraft. This approval further strengthens Bell’s commitment to providing advanced maintenance solutions and ensuring superior passenger comfort and operational performance across its fleet.
