Question: Plot the chord and pitch angle variation for a 30 cm diameter, two-bladed propeller in hover (no- oncoming velocity), operating at a rotational speed
Plot the chord and pitch angle variation for a 30 cm diameter, two-bladed propeller in hover (no- oncoming velocity), operating at a rotational speed of 2500 RPM, under the following design constraints: i) Angle of attack is fixed at 5 degrees for all radial positions ii) Sectional lift and drag coefficient for the airfoil cross section are 0.55 and 0.05 respectively iii) Total thrust is 1N iv) Hub diameter is 2 cm v) Assume a linear variation of the thrust along the blade such that the thrust at the tip is zero. Clearly explain the steps taken, and comment on the feasibility of the design.
