FLIGHT TEST DETERMINATION OF LATERAL STABILITY AND CONTROL DERIVATIVES FOR A SINGLE ROTOR HELICOPTERnPart I Equations of Motion, Analysis Techniques, Instrumentation, and Flight Shakedown

摘要

This report discusses the results of the first phase of a program aimed at experimentally investigating the lateral stability and control characteristics of a single rotor helicopter. The lateral equations of motion have been derived for the single rotor helicopter considering three rigid-body degrees of freedom. Means are presented for estimating the various physical and aero-dynamic characteristics of the XH03S-2 helicopter. Sample calculations are made in which the stability derivatives are found for the 70 mph case.
