Book Description
A series of experiments was performed in the Princeton Dynamic Model Track to determine the lateral/directional stability and control of a V/STOL type aircraft in ground proximity. Of primary interest were the characteristics associated with flight at high lift coefficients and utilizing high wing incidences with large flap deflections as may be encountered during STOL operations in landings and take-offs where the full or maximum effects of ground proximity are encountered. The configurations tested included combinations of wing incidence and flap deflection up to a maximum of 60 degrees.

Book Description
A wind-tunnel investigation was made of the aerodynamic stability, control, and performance characteristics of a model of a four-propeller tiltwing VTOL airplane employing flaps and speed brakes through the transition speed range. The wing was stalled for steady level flight for all conditions of the investigation; however, the flapped configuration did produce a higher maximum lift. The wing stall resulted in an appreciable reduction of aileron effectiveness during the transition. Out of ground effect the low horizontal tail did not appear to be in an adverse flow field as had been expected and showed no erratic changes in effectiveness; however, in ground effect a large nose-down moment was experienced by the model. It is concluded that the configuration is directionally stable and possesses positive dihedral effect throughout the transition, and the data show no signs of erratic flow at the vertical tails.
