Latest Patents

Sielaff holds a patent for a "Failsafe valve for geared rotary actuator." This invention provides 'Hole-In-The-Wall' failsafe functionality for thin-wing aircraft control surface actuation systems that utilize a geared rotary actuator powered by a hydraulic rotary motor. The failsafe valve is designed to ensure that the flight control surface can return to an aerodynamically neutral failsafe position in the event of a loss of electrical control or hydraulic pressure. When normal command pressure is received, the valve remains inactive, allowing the actuation system to function as intended. However, in failure scenarios, the valve activates to connect the motor hydraulic control lines to the case return line, ensuring that the control surface is safely repositioned.
