(FR) PALE DE ROUET DE COMPRESSEUR A RACCORDEMENT ELLIPTIQUE EVOLUTIF
Abstract: front page image
(EN)The invention relates to a compressor impeller that comprises at least one blade (24) connected to an impeller hub (26) by a curve-shaped connection, wherein said blade extends along a chord (27) defined between a leading edge and a trailing edge of the blade. The invention is characterised in that the connection has an elliptic shape (P, Q) that varies along the chord.
