Blade and blade dihedral angle
The invention relates to a compressor blade defined at each of the points on its surface by a sweep angle and a dihedral angle, comprising: -a root, -a tip, the distance between the root and the tip, measured along an axis referred to as the radial axis, perpendicular to an axis of rotation of the c...

| description | The invention relates to a compressor blade defined at each of the points on its surface by a sweep angle and a dihedral angle, comprising: -a root, -a tip, the distance between the root and the tip, measured along an axis referred to as the radial axis, perpendicular to an axis of rotation of the compressor, being referred to as the radial height (h), - a zone, comprised between the root and the tip, a first part of which has a strictly positive leading edge dihedral angle, and a second part of which has a strictly negative leading edge dihedral angle, - the zone of maximum dihedral angle being comprised, along said radial axis, between r = 0.25 h and r = 0,7 h. |
