A SERIES of laborious calculations of take‐off distance indicated the desirability of expressing propeller thrust as a function of speed in the take‐off range so that the ground run could be integrated directly. Propeller thrusts were estimated from REF. 2 for a wide range of disk loadings, solidities, and tip speeds. Plotting against speed shows that, for practical values, the assumption of linearity introduces a negligible error (see FIGS. 7–39).
