Autothrottle system for aircraft with fadec integration
The patent US11975861B2 describes a sophisticated system for controlling an autothrottle in aircraft equipped with a Full-Authority Digital Engine Control (FADEC) system. The system includes an autothrottle controller that utilizes processing circuitry and memory to execute an autothrottle control program. This controller receives sensed power-control input (PCL) position signaling, which indicates the manual throttle setting, and generates automated power command signaling based on a determined control-target setting. The FADEC interface is designed to select between the sensed PCL position signaling and the automated power command signaling, ensuring that the automated signals are synthesized to mimic the electrical characteristics of the sensed signals, making them recognizable by the FADEC system.
Additionally, the patent outlines various features of the system, including a default setting for the FADEC interface that prioritizes sensed PCL position signaling when the autothrottle control is disengaged. The autothrottle controller is designed for safe operation, ensuring that automated power command signaling is only selected when the controller is fully functional. The system also incorporates an angular position sensor to detect the manual throttle lever's position and can learn the electrical characteristics of the sensed PCL position signaling during its configuration. The method for controlling the autothrottle involves executing the control program, receiving and processing the PCL position signaling, and dynamically adjusting the automated power command signaling, all while maintaining the ability to transition between engaged and disengaged states based on manual throttle adjustments.
