A boundary integral or "panel" method is described for computing the threedimensional, steady state, potential flow about ship configurations with or without lifting surfaces in the presence of a free surface in an initially undisturbed sea. The low order method is characterized by a special modelling of the free surface boundary condition, by...

A discussion is given of the physical mechanisms governing the hydrodynamics of sailing yacht keels and the parameters that, through these mechanisms, determine keel performance. It is concluded that due to the presence of the free water surface optimum keel shapes differ from optimum shapes for aircraft wings, a fact that does not seem to have...

An engineering method for the design of airfoils having a prescribed pressure distribution in subsonic or transonic flow is described. The method is based on an iterative, "residual-correction" type of procedure. In each iteration step, the difference between the current and a target pressure distributions (residual) is determined by means of a...

An overview is provided of computational methods that can be used in solving the design problem of aerodynamics; i.e. the problem of finding the detailed shape of (parts of) configurations of which the gross geometric characteristics have already been determined in a preliminary, overall design process, and that, subject to certain constraints,...

Examples are discussed of the application of computational methods in aerodynamic design problems involving interference. Amongst these are: subsonic wing-body, sting support, pylon-nacelle and pylon-store interference, high-lift devices, induced drag minimization through constrained optimization in the Treftz-plane and transonic wing-fuselage...

Recent developments in computational fluid dynamics have led to a need for a data base against which results of various computational methods may be checked. As a test case for transonic flow around a commercial transport type configuration, the DFVLR-F'i wing body configuration has been selected by the GARTEUR Aerodynamics Action Group AD (AGOl...

Slooff, J.W. (author)
A review is given of some current new developments at NLR in integral equation ("panel") methods for the computation of potential flows. One of these developments concerns the exact modeling of (nonlinear) compressibility effects through field source distributions, in combination with the artificial viscosity, retarded density and flux-splitting...

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...

A computational method is presented for the design of "thick" wings with given pressure distribution in subsonic flow, in the presence of a body and/or other airplane components of fixed geometry. The method combines well-established linear techniques for the analysis of thick-wing configurations, and for the design of asymptotically thin wings....
