Outline of Final Research Achievements

Experimental techniques in a supersonic wind tunnel with Magnetic Suspension Balance System (MSBS) are developed in this research to suspend a model against starting load without mechanical support. The principal results were obtained as the following; a suspended model was accurately positioned at the center of a test section by the newly-developed fast response control system of MSBS, and the starting load was decreased by adjusting a total pressure within a setting chamber, making it possible to magnetically suspend a model in a supersonic wind tunnel testing.
