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, W.A. (author)The glass temperature (TG) of polymers is defined and methods for its determination are enumerated. The influence of rate of measurement, purity and condition of sample on observed TG' s and the interpretation of data and criteria for their assessment are discussed. TG's of 424 homopolymers are tabulated with a comprehensive bibliography of 353...report 1965

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), Westley, R. (author)Using experimental measurements of the sound pressure and phase in the near field of a choked screech jet, a method is proposed for computing the effective source positions, their strengths and phases. Two models are considered. The first assumes a distribution of point sourees along the jet axis and the second assumes ring sources along the jet...report 1971

Lee, B.H.K. (author)A theoretieal treatment of plane progressive sound waves of finite amplitude in a non-dissipative medium produced by a piston whose motion contains many different frequeney components is presented herein. The solution of the seeond-order wave equation is represented in the form of a Fourier series and the eoeffieients are expressed in terms of...report 1971

Lee, B.H.K. (author)The blast wave equations in an unsteady environment are derived. For wedge and conical nozzles it is shown th at the density has a power law vari ation with distance downstream from the throat when the loeal flow Mach number is large. The unsteady flow field behind the blast wave is solved by a perturbation technique and the sel f-similar...report 1968

Lee, B.H.K. (author), Ribner, H.S. (author)The propagation of a weak normal shock wave through a turbulent atmosphere is studied in terms of an idealized model. The turbulent field is assumed to be weak and represented by the superposition of two inclined shear waves of opposite inclination to the mean flow. The resulting flow is of a cellular nature. The cells are rectangular in shape...report 1972

Lee, B.B.K. (author), Tang, F.C. (author)A supercritical airfoil with a trailing edge flap has been the subject of aerodynamic investigation in the National Aeronautical Establishment's High Reynolds Number 2-D Test Facility. The effects of flap deflection on buffet intensities and delay of buffet onset at transonic speeds were studied. Buffet boundaries for various flap angles were...report 1988
