method of optimizing a flight path, non-transient media and system

摘要

a method, form, and system for receiving a mathematical model representation of performance characteristics for an aircraft and engine combination: performing a model order reduction in the mathematical model representation; eliminate, based on the projected model, fast dynamics components of the mathematical model representation; determine a reduced order model, such as a differential algebraic equation, where algebraic equations replace fast dynamics components; establish a flight path angle and throttle grip angle as a control to minimize fuel consumption for the combination of modeled aircraft and engine; discretize motion equations for the modeled aircraft and engine combination and formulate optimization equations as a nonlinear programming problem; and determine optimal open-cycle control that minimizes fuel consumption for the modeled aircraft and engine combination to climb to a set cruising altitude and speed.
