c Using the data in figure 4, such problems may be because of the low D/L assumed for the 22° blade solved. The drag of a locked propeller is easily found, setting, for it is evident that the cleaner the airplane since the drag coefficient remains constant and is equal the greater will be the… … the landing run. Figure 11.—Negative thrust and torque coefficients, nacelle mounted on biplane cellule—composite curves. DRAG OF LOCKED, IDLING, AND FREE-WHEELING PROPELLERS coefficient of a free-wheeling propeller also remains constant since the propeller is operating at nearly zero For the…
