Kellock, G.T.B. (author), Smith, E. (author), Sollars, A.R. (author)Single and double thermal cycle simulation of heat affected zone (HAZ) structures has been used to study the structural and property changes produced by submerged arc welding of HY 80 steel. The effectiveness of the temper bead technique and post-weld heat treatment at 650°C have also been examined, Marked degradation of impact properties occurs...report 1971

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, 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

Smith, E. (author)Structures representative of the visible weld heat-affected zone (HAZ) of a semi-killed C - Mn steel and a fully killed and normalised aluminium grain - refined C - Mn steel have been produced by means of a simulation technique. The Charpy V - notch impact properties have been assessed and related to microstructure. The only significant...report 1970

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, A.E. (author), Punter, T.J. (author)This paper determines the parameters of the gas flow from a 5 gm thrust propane attitude control jet and investigates the physical condition of the exhaust gas in a satellitet's environment. Theoretical investigations show that the propane gas has negligible effect on the attitude sensing systems of a satellite or on the optical systems of...report 1966

Smith, S.G. (author), Thomas, I.L. (author)Dead reckoning navigation systems making use of gyros have to take account of the earths rotation and the vehicles motion round the earth since these rotations will be sensed by the gyros. In general the gyro correction terms are functions of latitude and therefore the system generates a feedback loop whitin itself since the final output ...report 1966

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, K.G. (author)The linearised theory results of Nielson for the wave drag due to two and three dimensional types of surface waviness on circular cylinders are discussed, and compared with results obtained by using two dimensional linearised theory and slender body theory, and with the results for waviness on a flat plate. It is shown that for the types of...report 1965

Smith, K.J.C. (author)A Monte Carlo method of evaluating the stream function for a twodimensional, irrotational, incompressible flow into a bellmouth inlet is investigated. Considered as a Dirichlet problem, this method provides a numerical solution of Laplace' s equation by performing random walks from a test point Po to a point P1, chosen uniformly at random on the...report 1965
