The 505 Low Vibration Solution
Authors / Details: Peter Q. Romano, Michael S. Seifert, Michael R. Smith, Bell HelicopterAbstract
The original 505 Jet Ranger X prototype used a simple hard-mounted focal pylon to attach the transmission to the airframe. In developmental flight tests, the design resulted in 2/rev vibration levels that exceeded program objectives for ride quality in high speed forward flight. To address the vibration levels, a LIVE pylon mount was designed over a 4-month period to serve as a drop-in replacement with minimal impact to existing systems. An overview of the rapid design process is presented with supporting analysis and test data that led to its incorporation on the aircraft. The LIVE pylon design cut the vertical 2/rev vibrations in half, without negatively impacting existing structures, drive systems, flight controls, or handling qualities. The LIVE pylon mount is part of the Bell 505 Type Design that was certified in December 2016.
