2 and in Table L R=T-D-AD They are reduced to the usual coefficients of thrust, where power, and propulsive efficiency, T=the thrust of the propeller while operating in front of the body (the tension in the crank effect ive i hrust shaft). J9 = the drag of the airplane alone (without the p input… … Figure 7.—Fuselage and engine mounted on propeller research tunnel balance where D is the propeller diameter and n represents the In order to obtain the propulsive efficiency, which revolutions per unit time. Since the coefficients are includes the propeller-body interference, an effective…
