Using the McCormick approximation to blade propeller theory, determine the thrust power, torque power and efficiency of a 4 bladed 5868-9 Clarke-Y section propeller with a diameter of 1.8m, rotational speed of 3000 RPM, advance speed of 150kph and pitch of 15 at 75% of the blade radius operating at an altitude of 3000 m. Assume that the blade lift slope can be approximated by = 0.1 &1.0 + * [!\"] where t is the section thickness and the hub occupies about 5% of the blade radius. You may also assume that section drag polar for the blade is given by # = #,%&' + 0.01(( 0.15)) , where #,%&' = 0.004 + 0.017 8 * + 9.
