National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Development of Subsonic Base Pressure Prediction Methods, Volume I.

AD475670

Publication Date	1965
Personal Author	Butsko, J. E.; Carter, W. V.; Herman, W.
Page Count	156
Abstract	A combined analytic-experimental investigation of the subsonic base pressure phenomenon, especially as applied to blunt bodies typical of hypersonic flight vehicles, results in the development of a generalized method to predict base pressure in three-dimensional flow at subsonic speeds. A mathematical description of the fluid mechanics of steady two-dimensional subsonic base flow is developed. Two and three-dimensional wind tunnel testing of blunt based configurations is used to verify the two-dimensional analytic solution and obtain empirical relations which extend the analysis to three-dimensional base flow.
