Beschreibung
Zusammenfassung:	This invention relates to an impeller device for data acquisition in a flow. It comprises a support (3) with two bearing blocks (4.1, 4.2) to hold a spindle (2) around which the impeller (1) is fitted. The spindle (2) comprises two approximately conical ends (5). The bearing blocks (4.1, 4.2) are made from a material with the lowest possible coefficient of friction and each comprises an approximately conical recess (6) into which one of the ends (5) of the spindle (2) fit. Cette invention porte sur un dispositif à hélice pour l'acquisition de données dans un flux. Ce dispositif comprend un support (3) pourvu de deux blocs de support (4.1, 4.2) afin de retenir une broche (2) autour de laquelle est montée l'hélice (1). La broche (2) comprend deux extrémités approximativement coniques (5). Les blocs de support (4.1, 4.2) sont fabriqués dans un matériau ayant un coefficient de friction le plus bas possible et chacun comprend un évidement approximativement conique (6) dans lequel s'adapte une des extrémités (5) de la broche (2).
