Abstract
Base-pressure fluctuations behind a long cylinder (l/d ≈ 5–10) and the disk (l/ d ≈ 0.0) is investigated experimentally in this paper. The spectral and correlation characteristics of the base-pressure fluctuations behind axisymmetric bodies at a Mach number M ≲ 1.0 are generalized on the basis of the data obtained and the results of other authors.
