A Slim Type Universal Joint With Lockable Axes
Caner Turker, Mete Anakli and Ali Yetim
During flight tests of unmanned air platforms, any dysfunction may result catastrophic outcomes such as collapse of the platform. In order to prevent the platform hitting to the ground, flight test equipment is used to eliminate unwanted motion of the platform due to problems arise during tests. A flight test equipment generally lets the platform turns in pitch, roll and yaw axes as well as translational axes at specified test levels. In some tests, these rotational axes are requested to be fixed and tests can be performed only at desired axes. A new lockable axis joint is designed for the control of pitch and roll axes. This joint is compared with the other possible mechanisms (universal joint, separated axis mechanism) which can be used for constructing the pitch and roll axes of the flight test equipment. Detail design procedure, range of motion and strength analyses of the new joint are presented throughout the study. In addition, further usage, possible advantages and disadvantages of the new joint are discussed.
