Title
(EN) FAN BLADE DOVETAIL AND SPACER
(FR) QUEUE D'ARONDE DE PALE DE VENTILATEUR ET ENTRETOISE
Abstract
(EN)
A blade according to an exemplary aspect of the present disclosure includes, among other things, a radially inner dovetail supporting a radially outer airfoil; and the dovetail having a radial thickness which is less in a circumferentially center portion of the dovetail than circumferentially opposing outer edges.
(FR)
Une pale selon un aspect donné à titre d'exemple de la présente invention comprend, entre autres, une queue d'aronde radialement intérieure supportant une surface portante radialement extérieure; et la queue d'aronde présente une épaisseur radiale qui est inférieure au niveau d'une partie circonférentiellement centrale de la queue d'aronde par rapport aux bords extérieurs circonférentiellement opposés.
