摘要： A BLADED ROTOR FOR A GAS TURBINE ENGINE HAS A ROW OF BLADES, EACH BLADE HAVING TWO PART SPHERICALLY FACED DEPRESSIONS OF OPPOSITE FACES AND HOLES THROUGH THE BLADE THICKNESS WHICH LEAD INTO THE DEPRESSIONS. TIE MEMBERS EXTEND BETWEEN ADJACENT BLADES, THE ENDS OF THE TIE MEMBERS PASSING THROUGH THE HOLES AND BEING RETAINED BY PART SPHERICALLY FACE NUTS WHICH ENGAGE IN THE PART SPHERICAL DEPRESSIONS. THE TIE MEMBERS ARE THUS ALLOWED TO MOVE RELATIVE TO THE BLADES AND TO TAKE UP THE NATURAL POSITION WITHOUT STRESSING THE BLADE UNDULY.

摘要： A bladed rotor for a gas turbine engine comprising a row of blades in which each blade is tied to the next adjacent blade by a Z-shaped metal tie having a center section which is inwardly curved such that centrifugal forces acting on itself are evidenced as compressive stresses within the tie and end limbs or lugs extending from the center section in opposite directions generally chordally of the blades and each being attached to the blades by bolts spaced apart transversely of the blade, the bolts extending through the blade to also attach a similar limb or lug to the opposite blade face.
