Straightening of guide vanes
Abstract
Abstract A METHOD AND APPARATUS ARE DISCLOSED FOR RESTORING DISTORTED GUIDE VANES TO THEIR ORIGINAL SHAPE FOR PROPER LOCATION AND PERFORMANCE IN A FINAL VANE ASSEMBLY. A HEATED AIRFOIL SECTION HAVING LOCATING BUTTERESSES AT OPPOSITE ENDS THEREOF IS CLAMPED UNDER PRESSURE BETWEEN A PAIR OF HEATED DIES HAVING CONTOURED WORKING SURFACES DEFINING THE DESIRED AIRFOIL SHAPE, WITH THE BUTTRESSES OF THE VANE EXTENDING FREELY OUTSIDE THE DIES. THE PRESSURE IS MAINTAINED ON THE AIRFOIL UNTIL IT HAS CONFORMED TO THE CONFIGURATION DEFINE BY THE DIES AND, WHILE MAINTAINING THE PRESSURE ON THE AIRFOIL, THE FREELY EXTENDING BUTTRESSES ARE THEN ORIENTED RELATIVE TO THE AIRFOIL SECTION TO THE CORRECT ATTITUDE REQUIRED FOR PROPER LOCATION OF THE VANE IN THE FINAL VANE ASSEMBLY.
