Abstract

IN the previous article, the lateral stability of an aircraft was shown to depend upon the roots of a quartic equation in which the coefficients were obtained in terms of the resistance derivatives of the aeroplane. These derivatives were defined in a highly synthetic manner from a mathematical rather than a physical standpoint, so that their meaning is apt to be somewhat obscure. It is likely, however, that the use of symbols like lp is familiar to readers who are not otherwise acquainted with stability nomenclature, since these expressions arc commonly used in other aerodynamic topics such as rolling performance, spinning etc. It is important therefore to correlate the definitions given here with those given elsewhere and to establish their physical meanings.
