Friction characteristics of skewed roller brakes

open access: yes, 1998
The project sponsors design and manufacture skewed roller brake devices for use in aircraft flight control actuation systems. Design tools have previously been developed to predict the torque characteristics ofthese devices. A fundamental deficiency ofthese tools is the use ofempirical friction coefficient data gathered from a limited test sample ...
