Book Description

A brief study of available wind-tunnel data with regard to the variation of pitching moment with sideslip has been made. The results indicate that the effect of sideslip on the pitching moment can be large and is dependent upon a large number of factors. For example, it was found that wing plan form, wing position, horizontal-tail location, aileron location, and fuselage shape can have appreciable effects on the pitching moment due to sideslip. However, data at large sideslip angles are rather meager and a considerable amount of systematic experimental data is needed, especially at transonic and supersonic speeds.
