Theory of Subsonic Lifting Surface (Fixed Mode). Some Considerations and Propositions for Improving the Method of Numerical Solution . Teoria Della Superficie Portante Subsonica (Moto Permanente). Alcune Considerazioni E Proposte Per Migliorare UN Metodo di Soluzione Numerica

摘要

The problem of calculating coefficients in a system of linear algebraic equations that approximate the integral equations for the numerical solution of the equations for fixed subsonic lifting surfaces are examined according to the method of Zandbergen, Labrujere, and Wouton. It is shown that modifying the expressions for calculating the coefficients, and introducing a regulatory condition, it is possible to improve the numerical evaluation of terms which influence the coefficients, without complicating the computer programs.
