Lee, B.H.K. (author)A method for predicting the response of a wing to non-stationary buffet loads is presented. The wing is treated as a cantilever beam with known mass distribution. Using generalized co-ordinates, the vibration of the wing is governed by the second order mass-spring-damper oscillator equation. The buffet load on the wing is expressed as an...report 1979

Lee, B.H.K. (author)A method for the prediction of the response of a wing to nonstationary buffet loads is presented. The time history of the applied load is segmented into a number of time intervals. In each time segment, the nonstationary load is represented by the product of a deterministic shaping function and a statistically stationary random function. An...report 1980

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

Lee, B.H.K. (author), Ohman, L.H. (author)Buffet characteristics of the BGK No. 1 shockless airfoil have been investigated. Fluctuating pressure measurements along the airfoil chord and unsteady force balance data have been obtained in various regions inside the buffet régime close to the onset boundary curve. The Mach number range where buffet intensity reaches high values is...report 1983

Lee, S. (author), Munro, M. (author)This review is the first phase of a study of Matrix dominated properties of advanced composites materials for aerospace application. In this report, all the commonly used in-plane shear test methods are examined and discussed in detail. Using a decision analysis technique, three test methods are selected for further study.report 1984

Jones, D.J. (author), Lee, B.H.K. (author)As part of the study of the nonlinear response of structural components we investigate in this report a single degree-of-freedom nonlinear response equation usually known as Duffing's equation. Previously the response curves have been investigated analytically by many authors but there seems to have been very little numerical work done in the...report 1985

Lee, B.H.K. (author), LeBlanc, P. (author)Flutter analysis of a two-dimensional airfoil with a cubic nonlinear restoring force in the pitch degree of freedom is investigated. The structural dynamic equations of motion are integrated by a time marching finite difference scheme. Flutter is determined from conditions which give rise to either a divergent or limit-amplitude solution. Case...report 1986

Lee, B.H.K. (author), Desrochers, J. (author)Nonlinear flutter of a two-dimensional airfoil undergoing plunging and pitching motions is studied using a time marching finite difference scheme. The structural nonlinearity considered is of the type due to a spring with preload and freeplay. Flutter is determined from solutions of the structural dynamic equations of motion when either...report 1987
