An Analysis of Longitudinal Stability in Power-Off Flight with Charts for Use in Design,
Abstract
The longitudinal stability of aircraft has received very extensive and exhaustive treatment by able writers (see references and bibliography), but the classical treatment of the subject has been rather (difficult for those not familiar with higher mathematics. The study reported herein was undertaken with the purpose of making more understandable the mathematical treatment and of preparing a method of estimating stability characteristics that would be sufficiently accurate and rapid to appeal to practical designers. The section preceding the group of charts for determining stability characteristics in power-off flight is devoted to a derivation, in relatively simple terms, of the mathematical relationships and to a discussion of the formulas. The portion following the group of charts consists of an explanation of the method of using them. It is not necessary to read the first portion in order to use the charts with satisfactory results. All symbols not given in the report cover are defined where used and are also listed in the appendix.
