Arrangement of aerodynamic auxiliary surfaces for an aircraft

摘要

An arrangement of aerodynamic auxiliary surfaces is configured for being arranged on the underside of an aircraft and furthermore includes a longitudinal axis and at least one aerodynamic auxiliary surface, wherein the aerodynamic auxiliary surface is laterally offset referred to the longitudinal axis, and wherein the aerodynamic auxiliary surface is configured for generating vortices when it is subjected to an oncoming air flow. This makes it possible to compensate vortices caused by the shape of the aircraft such that the directional stability of the aircraft can be improved and the aerodynamic drag may be reduced.

主权项

1. An aircraft comprising:
a fuselage comprising a fuselage upsweep at a rear of the aircraft; at least one outwardly directed landing gear fairing in form of a sponson on the fuselage; and at least one arrangement positioned on an underside of the at least one landing gear fairing upstream of the fuselage upsweep, the arrangement having a longitudinal axis and comprising: a plurality of vortex generators arranged between a first edge and a second edge of the underside, said vortex generators being laterally offset relative to the longitudinal axis, and wherein said plurality of vortex generators is configured for generating vortices when said plurality of vortex generators is subjected to an oncoming air flow.
