1. An airplane weighs 36,000 lb. and has a wing area of 450 fte. The drag equation is C, =0.014 + 0.05C} . It is
desired to equip this airplane with turboprop engines with available power such that a maximum speed of
602.6 mph at sea level can be reached. The available power is assumed to be independent of flight speed.
Calculate the maximum rate of climb and the speed at which it occurs.

- Explain the mechanism of drag and lift force generation for the wing using Newton's law. Here are the hints : If the wing does not exist, the velocity distribution is uniform at v=U_inf. Therefore, the x-directional velocity of the air is deceralated by the wing. This implies that the wing applied a force in the -x-direction to the air (Newton's second law). In other words, the air flow applied a force in the x-direction to the wing (Newton's third law). This is the mechanism of drag generation.arrow_forwardQ.17.
