ABSTRACT	Many varied methods exist for the derivation of optimum aerofoil shapes by the combined use of numerical optimisation techniques (optimisers) and Computational Fluid Dynamics (CFD). Some are capable of optimisation at more than one design point (multi-point design). ESDU 99019 deals with the principles of the technique in general and, for illustration, the application of one such multi-point method (CODAS) in particular. ESDU 99019 gives an overall view of the optimisation design method and presents a general description of the constrained multivariable optimisation process. It also deals with some aspects of geometry definition and discusses the CFD methods involved. A brief survey of current optimisation methods is given. Examples of the use of aerofoil design optimisation methods are given in a sequence of companion ESDU documents. The first of these are: ESDU 99020, which considers a single design point, and ESDU 99021, which considers a case with two design points. In each of those examples the effects are considered of leading- and trailing-edge flap deflections and of camber line variations.
