Abstract
An automatic aircraft powerplant control system includes a throttle servo for adjusting a throttle valve via a throttle control linkage. A throttle control lever provides a user input to the throttle servo, and a throttle controller controls the throttle servo for controlling a throttle valve. A propeller servo is provided for adjusting a propeller governor setting of an engine. A propeller control lever provides a user input to the propeller servo, and a propeller controller controls the propeller servo. A mixture control servo is configured for providing a mixture control output to the engine via a mixture control linkage for adjusting an air-fuel mixture. A mixture controller is configured for controlling the mixture control servo.
Claims19
An automatic aircraft powerplant control system, comprising:
- a throttle control configuration for controlling a throttle, comprising:
- a throttle servo mechanically coupled with an engine via a throttle control linkage, wherein the throttle servo is configured for adjusting a throttle valve via the throttle control linkage;
- a throttle control lever communicatively coupled with the throttle servo for providing a user input to the throttle servo;
- and
- a throttle controller communicatively coupled with the throttle servo for controlling the throttle servo, wherein the throttle controller receives inputs from an avionics bus, and the throttle controller is configured to control the throttle servo for adjusting the throttle valve based at least partially on the inputs;
- a propeller control configuration for controlling a propeller, comprising:
- a propeller servo mechanically coupled with the engine via a propeller control linkage, wherein the propeller servo is configured for adjusting a propeller governor setting of the engine;
- a propeller control lever communicatively coupled with the propeller servo for providing a user input to the propeller servo;
- and
- a propeller controller communicatively coupled with the propeller servo for controlling the propeller servo;
- and
- a mixture control configuration for controlling an air-fuel mixture, comprising:
- a mixture control servo mechanically coupled with the engine via a mixture control linkage, wherein the mixture control servo is configured for providing a mixture control output to the engine via the mixture control linkage for adjusting the air-fuel mixture;
