den Boer, R.G. (author)A new postprocessing procedure is applied on the data, acquired in 1981 during the unsteady transonic pressure measurements on a transport-type supercritical wing (LANN-model), oscillating in pitch. The new procedure takes the influence into account of the local boundary layer on the dynamic response of the pressure tubes. This report presents...report 1989

Smith, J. (author)The applicability of two-dimensional flexible solid wall test sections for three-dimensional testing is theoretically investigated for linearized subsonic flow. The method uses known interference velocity distributions along a targer line (derived from a method of images for this particular study). From these, wall shapes are calculated that...report 1984

Vogelaar, H.L.J. (author)A description is given of the two-dimensional test setup in the pressurized wind tunnel HST of the NLR, for the testing of multiple airfoils at high Reynolds numbers. Results of the first tests with this setup are validated. For this validation a number of additional tests were performed in the HST as well as in the atmospheric wind tunnel HST 3...report 1983

Snel, H. (author)A brief description is given of a method, developed at NLR for the prediction of interference effects between (propulsion) jets and parts of airframes. The jet flow region is described by a model for a jet in a nonuniform mainflow, accounting for the presence of the airframe. The potential flow field around the airframe-jet combination is...report 1976
