    Abstract

    This is the closure report submitted to the project sponsors AR&DB at the AR&DB project review meeting held on 03/5/2003 at DISC, Bangalore . An experimental study of PSP measurements was undertaken on aircraft and slenderbody models in the 1 .2m trisonic wind tunnel . A major objective of this programme was to provide a correction method of the drop in total temperature of the tunnel on PSP data and estimate accuracy of PSP measurements in a blowdown wind tunnel environment. Tests were made at Mach numbers of 0 .6 and-0 .8 at angle of attack of 6° and 100. A correction method for temperature effects on PSP data was evaluated and found very effective. The PSP results (using above correction method) showed very good agreement with pressure port data on the aircraft model . The accuracy of PSP results so obtained are considered to be about as good as those obtained in wind tunnels elsewhere in the world at transonic speeds .
