The invention relates to a method for wiring suctions ((i), (i+1)) of a blade (1) for a blade row of a turbomachine. According to said method, a first central component (formula (II)) of a second section ((i+1)) is selected according to at least one central component ((formula (IV)), xCG(i), rCG(i)) of a first section ((i)), especially according to a formula (I) where: (i) is a variable of the first section; (i+1) is a variable of the second section; (formula (III)) is a central component of a section in the peripheral direction, preferably in the angular or radian measure; xCG is a central component of a section in the axial direction; rCG is a central component of a section in the radial direction;βis a graduated angle of a section; and (formula (V)) is a peripheral incline, preferably in the angular or radian measure.ΘCG ( i + 1 ) =ΘCG ( i ) + Arctan [ 2 · ( x CG ( i + 1 ) - x CG ( i ) ) ( r CG ( i + 1 ) + r CG ( i ) ) · tan (β( i + 1 ) +β( i ) 2 ) ] ( I ) ΘCG ( i + 1 ) ( II ) ΘCG ( III ) ΘCG ( i ) ( IV ) Θlean ( V )
