Abstract
The present disclosure provides methods and systems for controlling a propeller-driven aircraft powered by at least one gas turbine engine. A thrust change is obtained corresponding to a difference between an actual thrust and a desired thrust for an engine. When the thrust change is greater than a pre-determined threshold, a setting change to one or more control input(s) of the engine is determined. One or more commands are output to cause the setting change of the control input(s).
Claims20
A method for controlling a propeller-driven aircraft powered by at least one gas turbine engine, the method comprising:
- obtaining a thrust change corresponding to a difference between an actual thrust of the at least one engine and a desired thrust for the at least one engine;
- when the thrust change is greater than a threshold, determining a setting change to at least one control input of the at least one engine;
- and
- outputting at least one command to cause the setting change of the at least one control input.
An autothrottle system for at least one gas turbine engine of a propeller-driven aircraft, the system comprising:
- a processing unit;
- and
- a non-transitory computer-readable memory having stored thereon program instructions executable by the processing unit for:
- obtaining a thrust change corresponding to a difference between an actual thrust of the at least one engine and a desired thrust for the at least one engine;
- when the thrust change is greater than a threshold, determining a setting change to at least one control input of the at least one engine;
- and
- outputting at least one command to cause the setting change of the at least one control input.
A non-transitory computer readable medium having stored thereon program code for controlling a propeller-driven aircraft powered by at least one gas turbine engine, the program code comprising instructions executable by a processor for:
- obtaining a thrust change corresponding to a difference between an actual thrust of the at least one engine and a desired thrust for the at least one engine;
- when the thrust change is greater than a threshold, determining a setting change to at least one control input of the at least one engine;
- and
- outputting at least one command to cause the setting change of the at least one control input.
