Schijve, J. (author), Jacobs, F.A. (author), Tromp, P.J. (author)Comparative flight-simulation tests on four types of joints of 2024- T3 sheet material were carried out with and without application of the penetrant LPS-3. Types of joints were douhle strap joint with hi-lok bolts, asymmetric strap joint, lap joint with countersunk rivets and lap joint with dimpled holes. Observations on slip during the fatigue...report 1977

Edwards, J.B.W. (author)Measurements of the distribution of heat-transfer coefficient and static pressure have been made in free flight on the flat upper surface of a sharpedged delta wing of aspect ratio 1 (76º leading-edge sweepback) at 14° incidence. Two configurations were tested differing only in edge angle between upper and lower surfaces, being 26.50 and 900...report 1965

Lee, B.H.K. (author)A method for the prediction of the response of an elastic wing to random loads at flight conditions using rigid model wind tunnel pressure fluctuation measurements is presented. The wing is divided into panels or elements, and the load is computed from measured pressure fluctuations at the centre of each panel. A series representation with terms...report 1983

Swewell, R.T. (author), Pettit, K.G. (author)This report presents preliminary result s of an analysis of V-G-H records obtained during the summer of 1963 from a DC-4M aircraft engaged in precipitatien physics experiments . The results are preliminary in that a report re lating the turbulence ta a detailed meteorological analysis will be issued later. Recording time totalled approximately...report 1964

Fisher, W.A.P. (author), Winkworth, W.J. (author)The effect of clamping on the fatigue strength of joints in aluminium alloy is investigated experimentally. Tests on Z section stringers connected to long, slotted cleats give an endurance for tightly clamped joints about nine times that for unclamped joints. Tests of bolted joints in aluminium alloy sheet material show still greater improvement...report 1952

Schra, L. (author), Wanhill, R.J.H. (author)In 1991 a simple automated stress corrosion testing method called the ASCOR (Automated Stress corrosion Ring) test was developed to test aluminium alloys according to ASTM specification G49. The present investigation concentrated on evaluating two aspects of the test method: The SCC initiation criterion (2 % load decrease). The possibility of...report 1997

Gilbey, D.M. (author), Pearson, S. (author)The change in length of an edge or central crack in a metal sheet can be obtained by measuring the change in electrical resistance of the sheet containing the crack. This paper gives the theory of the method and the results of a computer programme designed to provide detailed calibration curves. The method has been used to measure crack...report 1966

Anscombe, A. (author), Williams, J. (author)This note considers some of the special problems of wind tunnel testing wich arise in high-lift work. Discussion is confined to current experience in the R.A.E. end N.P.L. low-speed wind tunnels, and refers mainly to tests on blowing over flaps or jet-flaps. Comments are made on suitable size of model, methods of feeding compressed air into...report 1956

Pearson, S. (author), Wadsworth, N.J. (author)A torsion microbalance has been developed for use as a molecular beam detector. Three types of balance were investigated, the most successful being one in which very small angular deflections were measured using an R. V. Jones type light beam amplifier. This balance was reasonably robust, had a period of 6 seconds, would withstand baking at....report 1963
