AIRCRAFT WAKE SENSING

A wake produced by a leader aircraft and experienced by a follower aircraft is sensed in the following manner. Measurements carried out by the follower aircraft are estimated (311) based on a simulated response of the follower aircraft to an estimated aerodynamic context (309). The estimated aerodyn...

Beschreibung
Zusammenfassung:	A wake produced by a leader aircraft and experienced by a follower aircraft is sensed in the following manner. Measurements carried out by the follower aircraft are estimated (311) based on a simulated response of the follower aircraft to an estimated aerodynamic context (309). The estimated aerodynamic context (309) includes a model of the wake and an estimated position of the follower aircraft with respect to the model of the wake. The estimated aerodynamic context (309) is adjusted (308) based on a comparison between the measurements that have been estimated (311) and actual measurements (312) carried out by the follower aircraft. The aforementioned estimation and adjustment operations are carried out iteratively. Information (313) on the wake is then extracted from the estimated aerodynamic context (309).
