Abstract
Traction fluid changes its property from liquid to solid by controlling the pressure. This phenomenon has potential to be applied to a new type of mechanical engaging or disengaging element as a starter-generator of an aircraft engine. This paper examines fundamental engaging characteristics of a half-toroidal variator on focusing the synchronization of 4 power rollers, power loss and corresponding temperature rise during liquid to solid drive transition by using a 350Nm torque capacity variator with an electro-hydraulic loading mechanism.
