Kuiper, H. (author), van der Wees, A.J. (author), Hendriks, C.F.W. (author), Labrujère, T.E. (author)NLR participates in the ECARF (European Computation Aerodynamics Research Project) "Optimum Design" project, developing an algorithm for multi-point airfoil design. Within the ECARP project a test case has been defined for two-point design with the aid of well-specified target pressure distributions. It appears that optimization of pressure...report 1995

Hounjet, M.H.L. (author)A new method ARSPSC is described for the calculation of steady and time-linearized unsteady subsonic potential flow about complex 2-D and 3-D configurations. The method belongs to the category of the so-called panel methods. Applications have been made to a 2-D oscillating flat plate, a 2-D multi-component airfoil with oscillating flap and a 3-D...report 1986

Houwink, R. (author)An outline is given of a first version of the computer programme LTRAFV for coupled unsteady transonic flow/turbxilent boundary layer computations. It is a combination of the LTRAN2-NLR programme and the lagentrainment method of Green. A comparison is made of theoretical and experimental results for the NACA64A006 airfoil with oscillating flap...report 1981

Boersen, S.J. (author)Pressure measurements have been carried out on 5 stations along a 7.5- caliber conically pointed circular cylinder at a Mach number of 2.3 and Reynolds numbers of 1.2; 4.8 and 11.1 x 106. Pressure distributions have been integrated to produce local normal force coefficients. Some pitot pressure surveys have been performed in the external flow...report 1975
