WebIn aeronautics, inertia coupling, also referred to as inertial coupling and inertial roll coupling, is a potentially catastrophic phenomenon of high-speed flight which caused the loss of aircraft and pilots before the design features to counter it (e.g. a big enough fin) were understood. It occurs when the inertia of a heavy fuselage exceeds the ability of the … WebRubber Rollers: A robust roller coupling design, ideal for boat drives, providing a very low stiffness at low torque which shifts the torsional resonance below idle speed and prevents gear chatter.
