The Aerodynamic Forces and Moments on a Spinning Model of the F4B-2 Airplane as Measured by the Spinning Balance
This is a 1935 NACA technical report, published by NASA's Technical Reports Server, on wind-tunnel measurements of a spinning 1/12-scale model of the Navy F4B-2 biplane fighter, taken with a spinning balance. The pictures are plain engineering plots of aerodynamic coefficients against angle of attack and sideslip for different fin and rudder setups, plus one photograph of the model in flight, offering a designer little beyond the model's silhouette and the cruciform tail shape.
