Aerospace Instrument-Making Annotation << Back INFORMATION-MEASURING AND CONTROL SYSTEM OF WIND TUNNEL T-203 FSUE «SIBERIAN AERONAUTICAL RESEARCH INSTITUTE NAMED AFTER S.A. CHAPLYGIN» Yu.K. Blokin-Mechtalin, V.V. Petronevich, V.M. Pischasov Describes information-measuring and control system of wind tunnel T-203 FSUE «Siberian Aeronautical Research Institute named after S.A. Chaplygin», which was mounted on the stage of reconstruction of wind tunnel. Modernization of aerodynamic balance system AV-203 and AVM2-203 has been performed with replacement of the mechanical weight elements by strain gauge type (tenzometric) weight elements. T-203 was equipped with modern hardware, communication system and software, which allows you to perform all range of experimental research. This work was performed according to requirements to the metrological support of this research. Key words: aerodynamic experiment, information-measuring system, software, metrology.
