Bij computergesteund ontwerpen (CAD) is het nodig om gegevensuitwisseling tussen verschillende rekenprocessen en processen voor gegevensbehandeling technisch en organisatorisch mogelijk te maken. Dit komt neer op koppeling van de voor CAD gebruikte apparatuur en programmatuur. Kwaliteitsborging van de informatie is hierbij vereist. De onderling...

For a number of direct calculation methods for the prediction of flows around wings at subsonic speed, the basic assumptions are discxissed. This forms the basis of the demonstration of the applicability of the methods. Comparison of calculated pressvire distributions with results from windtunnel tests serve to illustrate this for three...
