Experimental investigation of the effects of viscosity on the drag and base pressure of bodies of revolution at a Mach number 1.5
Author(s): Chapman, Dean R; Perkins, Edward W
Abstract: Models were tested to evaluate effects of Reynolds number for both laminar and turbulent boundary layers. Principal geometric variables investigated were afterbody shape and length-diameter ratio. Force tests and ...

Investigation of the drag of various axially symmetric nose shapes of fineness ratio 3 for Mach numbers from 1.24 to 7.4
Author(s): Perkins, Edward W; Jorgensen, Leland H; Sommer, Simon C
Abstract: Experimental drag measurements at zero angle of attack for various theoretical minimum drag nose shapes, hemispherically blunted cones, and other more common profiles of fineness ratios of about 3 are compared with ...

Added to NTRS: 2009-01-14
Accession Number: 93R20312; Document ID: 19930091022; Report Number: NACA-TR-1386
A study of effects of viscosity on flow over slender inclined bodies of revolution
Author(s): Allen, H Julian; Perkins, Edward W
Abstract: The observed flow field about slender inclined bodies of revolution is compared with the calculated characteristics based upon potential theory. The comparison is instructive in indicating the manner in which the effects of ...

Investigation of some wake vortex characteristics of an inclined ogive-cylinder body at Mach number 2
Author(s): Jorgensen, Leland H; Perkins, Edward W
Abstract: For a body consisting of a fineness-ratio-3 ogival nose tangent to a cylindrical afterbody 7.3 diameters long, pitot-pressure distributions in the flow field, pressure distributions over the body, and downwash distributions ...

Comparison of the experimental and theoretical distribution of lift on a slender inclined body of revolution at M = 2
Author(s): Perkins, Edward W; Kuehn, Donald M
Abstract: Pressure distributions and force characteristics have been determined for a body of revolution consisting of a fineness ratio 5.75, circular-arc, ogival nose tangent to a cylindrical afterbody for an angle-of-attack range of ...

Characteristics of flow over inclined bodies of revolution
Author(s): Allen, H Julian; Perkins, Edward W
Abstract: Experimental force, moment, and center-of-pressure variations for a large number of bodies of revolution have been compared with the calculated characteristics based on the approximate theory developed in NACA-RM-A9I26. The ...
