ABSTRACT	This paper summarizes the works on the test section area as part of a whole-scale refurbishment of the NAL 2m×2m transonic wind tunnel.The area ranges from the upstream settling chamber to the downstream high-speed diffuser end corner vane.The works were started in April 1988 and were completed in March 1994,and include the replacement of the test section master control system,the flexible nozzle control system,and several driving mechanisms associated with the test section configuration changes.Descriptions are given of the process and the content of the refurbishment together with the improvement in performance.
