ABSTRACT:
An area measurement device for determining the single vane throat area of a nozzle guide vane with inner and outer bands adapted for assembly in a ring of vanes having a close tolerance cold throat flow area through the entire ring annulus and wherein each of the guide vanes includes aft radial reference surfaces and a radially outwardly directed side reference surface locatable on internal engine support surfaces for positioning the vane within an engine annulus support assembly. Each vane also has an inner band locater hole for fixedly securing the inner band of the nozzle to an internally located engine support. The device has gages of the self-mastering type and includes a latch mechanism for setting the device in a vane height measurement position or in a vane throat measurement position; a single nozzle vane is installed on the device on two spaced reference surfaces thereon corresponding to radial engine annulus locating surfaces and the gage further includes a locating pin to align the inner band locater hole in its engine position; a third reference surface circumferentially locates the outer band of the vane in an engine mounted position.
