Recent experimental investigations on small-chord controls in two-dimensional flow suggest that such controls are more efficient than wide-chord controls. The experiments also suggest that a further gain is obtained if the ...

Following flight experience of a particular aircraft, the effect of including a bob-weight and feel spring in the circuit of a power-operated longitudinal control on the dynamic stability of the aircraft is investigated. ...

The methods at present available for the estimation of the usual longitudinal and lateral stability derivatives of an airoraft are briefly discussed for each derivative in turn. This is preoeded by an introductory seotion ...
