Features
- Trim Servo used to provide AFCS control of the elevators
- Contains a servo motor with amplifier and an engage clutch, as well as a torque sensor for trim command generation
- Outputs a dual-channel trim sense signal with a scale factor of 100mV/in-lb, with a positive differential voltage representing CW torque
- Maximum sensed torque is at least 20 in-lb in each direction
- Also contains a tach feedback signal to provide servo motion sensing
- Outputs a differential signal with a scale factor of approximately 5.3V for full servo speed
- Is installed with a KM 275 servo mount, which contains a slip clutch for pilot override
- The servo receives a differential command input and drives the servo motor with a speed proportional to the magnitued of the command
- The command polarity will determine direction of the servo rotation
- The command inputs have an impedance of at least 15K ohms
- The interface is designed such that an open command signal will not cause a servo drive of more than 25% of full-scale speed
- Contains a validity circuit which compares the motor voltage against the servo command
- The actuator outputs a open/ground discrete signal, where ground represents a valid servo
- If the comparison fails, the servo outputs an invalid signal to the FCC
