Abstract
As a part of studies on the aerodynamic characteristics of rectangular sails, the writer performed wind tunnel experiments on the sail models indicated in Table 1. A sketch of the apparatus used in measurements of lift, drag and centre of pressure to various angles of attack is shown in Fig.1. Table 2 indicates the Reynolds Numbers and effective angles of attack α in each measurement. Their coefficient about each model expressed by equations (1), and the stalling angles and maximum lift coefficient with parameter camber are obtained as shown in Figs.2-7. Then, making use of these results obtained by the writer, coefficients of maximum thrust C_t and side force C_s at the same time expressed by equations (2) against θ_a, the directions of apparent wind from bow, are shown in Figs.8-9, and its angles of attack α_m are indicated in Fig.10. Some discussions of the findings are presented.
