NASA Center: Langley Research Center Publication Year: 1950 Added to NTRS: 2009-01-14 Accession Number: 93R21346; Document ID: 19930092056; Report Number: NACA-TR-999 Compressibility Effects in Aeronautical Engineering Author(s): Stack, John Abstract: Compressible-flow research, while a relatively new field in aeronautics, is very old, dating back almost to the development of the first firearm. Over the last hundred years, researches have been conducted in the ballistics ... NASA Center: Langley Research Center, NACA (Unspecified Center) Publication Year: 1941 Added to NTRS: 2008-01-28 Document ID: 20070026133; Report Number: NACA-ACR-207, NACA-SR-207 The compressibility bubble Author(s): Stack, John Abstract: Simultaneous air-flow photographs and pressure-distribution measurements have been made of the NACA 4412 airfoil at high speeds in order to determine the physical nature of the compressibility bubble. The flow photographs ...

The operation of the tunnel is also described and the method of presenting the data is given. An account of an ... NASA Center: Langley Research Center Publication Year: 1934 Added to NTRS: 2006-11-06 Accession Number: 93R20827; Document ID: 19930091537; Report Number: NACA-TR-463 Tests of airfoils designed to delay the compressibility burble Author(s): Stack, John Abstract: Fundamental investigations of compressibility phenomena for airfoils have shown that serious adverse changes of aerodynamic characteristics occur as the local speed over the surface exceeds the local speed of sound. These ...
