Abstract

Several experiments Involving two-dimensional and axisymmetric bodies have been carried out In a Trisonic WIND TUNNEL at supersmuc speeds to Investigate and analyse the measured values of BASE PRESSURE and to compare them with those from the theoretical methods. The objective of the experiments was to obtaln an appropriate method for processing the results of WIND TUNNEL tests on rockets or alrcraft having base area, hence, base drag. Among numerous semi-empirical methods avallablefor two-dimensional and axisymmetric geometry, the methods presented by Chapman, Korst and Tanner have been utilized to calculate values of BASE PRESSURE for comparison with the experimental flndings for the same modeL The results indicate that the pressure increasefor the 1-D model with a steplike base is greater that of the AXISYMMETRIC MODEL with the same conditions. The experimental results for all cases considered in this investigation compare weli with thosefram existing the theoretical method developed by Tanner
