Theoretical assessment of the general stability and gust response characteristics of STOL aircraft

Abstract

Results are presented of theoretical studies into the likely stability and gust response characteristics of four distinct classes of STOL aircraft, namely those using low wing loading and high CLmax alone, partly jet-borne configurations, aircraft using jet-flap-type wing-lift augmentation, and designs exploiting propeller slipstream. The areas considered are gust sensitivity, cross-wind control, dynamic response to gusts, speed stability, stability in flight under attitude constraint and dynamic longitudinal and lateral stability with fixed controls.
