An object intended to rotate in a flow of air (F), comprising a plate () with a general planar aspect and globally extending along a plane, the plate () comprising: a rear face () having a central area () on which an operator () is intended to exert a pressure force (F) either directly or via a support; a front face () intended to receive the flow of air; a peripheral portion (); and a main portion () extending between the peripheral portion; the plate having a stable shape at rest, the plate having a shape in use such that: 2110120124. The object (; ; ) according to claim 1 , characterized in that the plate () claim 1 , on at least 90% of the surface area of the rear face () claim 1 , has a thickness (e) comprised between 5 and 500 μm claim 1 , preferably between 10 and 200 μm claim 1 , and a basis weight comprised between 10 and 200 g/m claim 1 , preferably between 20 and 100 g/m.31101201102101820222426283032. The object (; ; ) according to claim 1 , characterized in that the peripheral portion ( claim 1 , ) of the plate comprises one or several areas ( claim 1 , claim 1 , claim 1 , claim 1 , claim 1 , claim 1 , claim 1 , ) which cannot be developed.4110120110210. The object (; ; ) according to claim 1 , characterized in that the peripheral portions ( claim 1 , ) comprises at least one area forming with the plane (P) claim 1 , at rest claim 1 , an average angle (α claim 1 , β) greater than or equal to 10° claim 1 , preferably greater than or equal to 30°.5201214211842104826. The object () according to claim 1 , characterized in that the plate () comprises claim 1 , at rest claim 1 , at least one convex area (-) for which the convexity is oriented from the front face () towards the rear face () claim 1 , and at least one other convex area () for which the convexity is turned from the rear face () to the front face () claim 1 , so that the plate () may be reversibly used by the operator ().6110120122. The object (; ; ) according to claim 1 , characterized in that ...
