Abstract
Method and device for an optimal management of the energy of an aircraft. The device (1) includes means (5) for determining, in an iterative manner, according to a predicted energy state and according to a management strategy, optimal commands of means (S1,S2, S3, S4, S5, S6) for controlling the energy of the aircraft, which allow the aircraft to reach a given point of a trajectory in a given operational state.
Claims14
An optimized energy management method for an aircraft, upon a flight along a predetermined trajectory so as to join a given point of said trajectory in a given operational state characterized by a set of constraints, a method wherein, upon the flight of the aircraft along said trajectory until said given point, automatically and repetitively, the sequence of successive steps is implemented as follow:
- a) the current values of parameters of the aircraft are determined;
- b) the predicted energy state of the aircraft at said point is calculated with the help of at least one prediction module (12) as a function of these current values and predetermined models, and iteratively as a function of the predicted energy state, optimized command orders of means (S1, S2, S3, S4, S5, S6) for controlling the aircraft energy are determined with the help of at least one optimization module (Cn), according to a management strategy, said optimized command orders being such that they allow the aircraft to reach said given point in the given operational state;
- and
- c) the optimized command orders being thus determined are applied to said energy control means (S1, S2, S3, S4, S5, S6) for the aircraft,
- a method according to which a plurality of different modes is provided, each of which is associated with particular energy control means and, as a function of the management strategy used at step b), a priority order of said modes enabling the selection of the mode being used is determined through a mode management module (11).
