Method and rotary-wing aircraft provided with a stabilisation means minimising the attitude hump phenomenon

摘要

The method involves positioning a lower stabilization unit (20) in a wake (8) of an upper stabilization unit (10), where the wake is generated by an airflow (7) passing through a rotary wing (5) by impacting an upper surface (10') of the upper stabilization unit. The upper stabilization unit is positioned between a first plane (P1) passing through the lower stabilization unit and a second plane (P2) containing the rotary wing, where the upper stabilization unit has upper stabilizing surfaces (11) with a upper leading edge (13) and an upper trailing edge (14). An independent claim is also included for a rotary-wing aircraft comprising a cell extending longitudinally from a front end to a rear end.
