Definition System and Criteria Related to the Static Stability of Airplanes ( First Report ) — Definition System , Static Flight Speed Stability , and Static Angle of Attack Stability —
This paper discusses the static stability concepts of airplanes. The definition of static stability has not been systematically discussed. For example, although “Cmα < 0,” “C β < 0,” and “Cnβ > 0” are merely the aerodynamic criteria corresponding to each static stability, they are used just like the definition of static stability. Moreover, “flight path stability” is well known as the static st...
