An Evaluation of the Longitudinal Dynamic Stability of an Aircraft at Stall.

Abstract

The longitudinal stability of an aircraft at or near stall was examined using the digital computer as an experimental tool to solve the longitudinal equations of motion. A linear analysis determined the effect of lift curve slope variation. An investigation was made to identify the nonlinear lift curve variations needed to create the often observed 'rocking-chair' or 'porpoising' stall trait. The characteristics of this limit-cycle oscillation were examined. (Author)
