First Claim
Patent Images
1. A rotorcraft autopilot system, comprising:
- a series actuator connecting a cockpit control component to a swashplate of a rotorcraft, the series actuator to modify a control input from the cockpit control component to the swashplate through a downstream control component; and
a differential friction system connected to the cockpit control component, the differential friction system to control the series actuator to automatically adjust a position of the cockpit control component during rotorcraft flight based, in part, on a flight mode of the rotorcraft.

Abstract
A rotorcraft autopilot system includes a series actuator connecting a cockpit control component to a swashplate of a rotorcraft, the series actuator to modify a control input from the cockpit control component to the swashplate through a downstream control component. The rotorcraft autopilot system also includes a differential friction system connected to the cockpit control component, the differential friction system to control the series actuator to automatically adjust a position of the cockpit control component during rotorcraft flight based, in part, on a flight mode of the rotorcraft.

9. A method, comprising:
-
determining a flight mode of a rotorcraft; identifying a swashplate position of the rotorcraft corresponding to the determined flight mode; and adjusting a cockpit control position of a rotorcraft cockpit control component based on a differential friction across a series actuator connecting the cockpit control component to the swashplate, the adjusted cockpit control position to match the identified swashplate position. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for controlling rotorcraft flight, the method comprising:
-
adjusting a differential friction between an upstream linkage and a downstream linkage relative to a series actuator to allow movement of the upstream linkage and prevent movement of the downstream linkage; and controlling actuation of the series actuator in response to the adjusted differential friction between the upstream linkage and the downstream linkage. - View Dependent Claims (17, 18, 19)
