Advanced speed test

An advanced speed test was carried out, and the fulfillment of the design speed was verified. The advanced speed of ISiMI with respect to the propeller's rpm was determined, as shown in Fig. 11. The design speed (1 m/s) was reached at a propeller speed of about 1,000 rpm. By extrapolating the results shown in Fig. 11, it is estimated that the maximum speed (2 m/sec) was reached at 1,650 rpm.
