Book Description
Presented are lift, drag, and pitching-moment data, neutral points, and the effects of power, flap deflection, and free elevator for the model at zero angle of yaw. The lateral-stability parameters and tests for a yaw range including rudder-free data are also presented.

Book Description
The results of wind-tunnel of a single-engine single-rotation airplane model indicated that, although extreme asymmetry in the horizontal tail showed a reduction in power effects on the longitudinal stability of the model, the particular "practical" arrangement tested did not show marked improvement. Disagreement between tests and analyses indicated the necessity for continued research to determine the characteristics of the slipstream behind various propeller-fuselage-wing combinations. Out-of-trim lateral forces and moments of the unsymmetrical tail arrangements that were best from consideration of longitudinal stability were no greater than those of the normal tail arrangement.

Book Description
The tunnel-induced upwash for a wing of any plan form and load distribution in a rectangular tunnel may be found with the aid of only two charts. One is given in the present paper. The second must be computed for each tunnel. The second chart is given for an open tunnel of 2:1 width-height ratio, a closed tunnel of 2:5 width-height ratio, and a closed tunnel of 10:7 width-height ratio.
