A study of the dimensions of the wake and of the radial distribution of the gas velocity in the wake behind a blunt body moving at hypersonic velocity

We present a method for experimentally studying in a ballistic range the dimensions of the turbulent wake behind a blunt body moving in air at hypersonic speed; included also in our results is the radial distribution of the gas velocity in the wake.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 3, pp. 165–168, May–June, 1976.The author thanks N. N. Baulin, A. S. Mkrtumov, and Yu. N. Urbanovich for their help in carrying out the experimental work.
