- Summary:
- Results are given of pressure-distribution measurements made in flight over the right wing cellule and the right half of the horizontal tail surfaces of a dive bombing biplane. Simultaneous measurements were also taken of the air speed, control-surface positions, control forces, and normal accelerations during various abrupt maneuvers in a vertical plane. These maneuvers consisted of push-downs and pull-ups from level flight, dives, and dive pull-outs, and push-ups from inverted flight.
- In addition to the pressure measurements, flight tests were made to obtain (1) wing-fabric deflections during dives and (2) variation of the minimum drag coefficient with Reynolds number. Supplementary tests were also made in the full-scale wind tunnel to obtain the characteristics of the airplane under various propeller conditions and with various tail settings.
