- Summary:
- The results of take-off calculations are given for an application of simple trailing-edge flaps to two hypothetical flying boats, one having medium wing and power loadings and consequently considerable excess of thrust over total resistance during the take-off run, the other having high wing and power loadings and a very low excess thrust.
- For these seaplanes the effect of downward flap settings was: (1) to increase the total resistance below the stalling speed, (2) to decrease the get-away speed, (3) to improve the take-off performance, and (4) to hinder the take-off of the seaplane having low excess thrust. It is indicated that flaps would allow a decrease in the highangles of wing settings necessary with most seaplanes, provided that the excess thrust is not too low.
