Winter, K.G. (author), Smith, K.G. (author)The measurements, using razor blade surface pitot tubes, show that the relatively mild pressure gradients and streamline convergence on the wing have a large effect on local skin friction. Application of the boundary layer momentum equation suggests that the change in skin friction arises directly from changes in the boundary layer profile....report 1965

Smith, E. (author), Apps, R.L. (author)A simulation technique has been employed to exannine the structures and properties of the heat affected zone in single and multipass submerged arc welds in QT 35 steel fora range of heat inputs i.e. 1.2, 2.1, and 4.2 kJ/mm (30, 54, and 108 kJ/in). Mechanical properties were assessed using Charpy V-notch, tensile and hardness tests and related to...report 1970

Maarsingh, R.A. (author), Labrujère, T.E. (author), Smith, J. (author)The present paper describes two alternative correction methods for wall interference based on measured boundary conditions. In both methods it is assipied that at or near the tunnel boundary the flow velocity will be measured in magnitude and direction and that the main part of the flow field may be considered irrotational and subsonic. One...report 1984

Smith, E. (author)Dimensional changes and the development of cracking in the Charpy V-notch impact test have been studied using a low energy blow technique. Notch opening, angle of bend, notch root contraction and lateral expansion are shown to be proportional to the energy of the low blow which does not cause complete fracture and to be relatively independent of...report 1973

Smith, R.E. (author)The directional handling qualities criteria for an instrument approach task in controlled turbulence were determined using an airborne V/STOL simulator, and compared with the re sults for a visual approach task , to show that instrument flight demanded more stringent criteria . Increasing the weathercock stability, in the presence of turbulence,...report 1966

Smith, J. (author)Modern developments in wind tunnel wall correction methods are for a major part directed towards the use of in situ measured boundary conditions in order to eliminate the need to describe the complicated aerodynamic characteristics of test section walls. This paper presents a short general review of the principles of such methods for 2D flow....report 1982

Smith, J. (author)The applicability of a multi-velocity-component static pipe, proposed by CALSPAN ATC, for measuring boundary velocity vector distributions in behalf of wall interference assessment, has been explored in two-dimensional flow. Comparisons with alternative methods to derive the local flow angle from measured pipe pressures as well as analyses of...report 1985

Allen, D. (author), Smith, E. (author), Apps, R.L. (author)Notch toughness, tensile and hardness properties of a normalised and tempered Mn-Cr-Mo-V steel have been determined after thermal cycling to 1275º C in simulation of thermal cycles experienced in the coarse grained region of the heat affected zone (HAZ). The metallurgical structure was investigated by means of optical microscopy and electron...report 1970

Smith, K.G. (author), Winter, K.G. (author)Results are given for the boundary layer allowance on the walls of the tunnel calculated by the method of Tucker. A preliminary calibration of the working section flow has shown that the calculated values of displacement thickness are correct to within about 5%. The approximate methods of Rogers and Davis and Ruptash are in fair agreement with...report 1961

Smith, K.G. (author)Graphs are provided giving the local and mean skin friction coefficients in laminar and turbulent boundary layers on flat plates with zero heat transfer. The curves cover Mach numbers up to 5 and Reynolds numbers between 10(5) and 10(8). Methods of estimating the skin friction drag of wind tunnel models are considered. The skin friction curves...report 1964
