Abstract
Various implementations described herein are related to an aircraft having a multi-engine configuration with multiple engines. The aircraft may have a flight control system coupled to the multiple engines with a multi-engine interface. The flight control system may be configured to reduce fuel consumption of at least one engine of the multiple engines during reduced-engine operation by pulse modulating fuel delivery to the at least one engine of the multiple engines.
Claims15
An aircraft comprising:
- a multi-engine configuration with multiple engines;
- and
- a flight control system coupled to the multiple engines with a multi-engine interface, wherein the flight control system is configured to:
- reduce fuel consumption of at least one engine of the multiple engines during reduced-engine operation by pulse modulating fuel delivery to the at least one engine of the multiple engines;
- calculate a minimum altitude of the aircraft for reduced-engine operation;
- and
- restart the at least one engine if a current altitude of the aircraft drops below the minimum altitude.
4 more elements
A method comprising:
- interfacing with multiple engines in an aircraft, the aircraft having a multiple engine configuration;
- continuously calculating a minimum altitude of the aircraft for reduced-engine operation;
- reducing fuel consumption of at least one engine of the multiple engines by pulse modulating fuel delivery to the at least one engine of the multiple engines during the reduced-engine operation;
- and
- restarting the at least one engine if a current altitude of the aircraft drops below the minimum altitude.
