Full-scale front fans were designed and tested with satisfactory results. The flow field in passing through the fans was estimated with a powerful method called streamline-curvature technique, and the first test-program was carried out in equipping the rotor blade row without snubbers (part-span shroud) and the second conducted with them. The detailed analyses of the test results showed that the snubbers had some effect on the operation of a fan stage at all locations within the stage and not only in locations locally near to the snubbers.
