van der Vooren, J. (author), van der Kolk, J.T. (author), Slooff, J.W. (author)A description will be presented of a computer program system that is being used for the prediction of aircraft steady aerodynamic characteristics. Properties of the system are described from two different viewpoints. One is that of the aerodynamic designer, who needs an information system to predict lift, moment and drag characteristics and to...report 1982

van Egmond, J.A. (author), Rozendal, D. (author)The design and experimental verification of a thick (18 %), shock free airfoil is described. The design was performed, using the NLR hodograph theory for transonic airfoil design. The airfoil was experimentally investigated in the NLR Pilot tunnel.report 1978

Kooi, J.W. (author)An experiment is described in which a nominal normal shock impinges on a turbulent flat plate boundary layer. The wall pressure distribution in the interaction region was measured for Mach numbers in front of the shock of 1.40, 1.44 and 1.46. The Reynolds number based on shock position was 18 X 10(6) and based on momentum thickness at the start...report 1978

Tijdeman, H. (author)Exploratory wind-tunnel experiments in high-subsonic and transonic flow on a conventional airfoil with oscillating flap and a supercritical airfoil oscillating in pitch are described. In the analysis of the experimental results, emphasis is placed upon the typical aspects of transonic flow, namely the interaction between the steady and unsteady...report 1977

Zandbergen, T. (author), Maarsingh, R.A. (author), Joosen, C.J.J. (author)With the intent to test the qualities of the theoretical models used in two different calculation methods, pressure distributions have been measured on a simple half model wing-in-jet combination. The position of the jets relative to the wing was varied, mainly in a plane perpendicular to the span. Jet velocities of 1, 2 and 3 times the tunnel...report 1977
