ABSTRACT	The nozzle of the 1m×1m supersonic wind tunnel of the National Aerospace Laboratory was partially repaired.After the measurement of the nozzle shape dimensions by using a laser measuring instrument the shape was adjusted to approach to the designed dimensions.The rubber seal was exchanged to a new one.After the repair,the inclination of the flow in the test section was measured using a five hole pitot tube and the AGARD-B standard model.Mach number distributions along the nozzle and cross-section of the test section were measured by the static pressures and the pitot tube.The flow characteristics are close to the one initially designed.
