The Application of Linear Maximum Likelihood Estimation of Aerodynamic Derivatives for the Bell-205 and Bell-206 (Application de la Methode du Meilleur Estimateur Lineaire pour le Calcul des Derivees Aerodynamiques du Bell-205 et du Bell-206).

Abstract

Parameter identification from flight test data of fixed-wing aircraft is currently a common procedure for application to aircraft development work, validation of simulation, flight simulator verification, flight control systems synthesis, aircraft handling qualities, flight envelope expansion and airplane certification. Similar work on the identification of the more complex helicopter system is currently still in the research stage. This report describes a number of flight test experiments involving the application of parameter estimation techniques to helicopters in order to determine the stability and control derivatives and to obtain information to identify improvements in the structure of the helicopter model. Keywords: Canada, Translations, Bell helicopter, Flight stability tests, Parameter identification, Aerodynamic stability.
