Automated method for optimizing aircraft engine power and speed
The patent US12030658B2 outlines an automated method and system for controlling an aircraft's autothrottle to optimize fuel efficiency during flight. The method involves a series of steps where the autothrottle system reduces engine power to slow the aircraft incrementally from a prior airspeed to a reduced airspeed. It then compares the rates of energy consumption (specifically fuel flow rates) at both airspeeds. If the energy consumption at the reduced airspeed is lower, the system continues to reduce power; if not, it increases engine power to achieve a more efficient operating airspeed. This process can be repeated to ensure the aircraft operates at optimal efficiency, defined as the airspeed where the lift-to-drag ratio is maximized under current conditions.
Additionally, the patent describes a system that includes an autothrottle controller with processing capabilities, memory, and inputs from airspeed and energy consumption sensors. The controller executes a flight endurance program that automates the throttle adjustments based on real-time data. The increments for speed adjustments are specified as 2 knots for the first and third increments, and 4 knots for the second increment. The system is designed to stabilize energy consumption before making further comparisons, ensuring that the aircraft maintains an efficient flight profile throughout its operation. This innovation aims to enhance fuel efficiency and operational performance in aviation.
