ABSTRACT |
In this study,the flying qualities of the Flight Research Airplane Do228 were evaluated.By performing some flight tests using a Do228,the V-Gamma diagrams with some configurations were drawn out.The flight performance was obtained,and some longitudinal aerodynamic derivatives such as Xu,Xw,Zu and Zw were estimated from performance.The parameter errors were examined by comparing the above parameters with those based on the wind-tunnel tests.According to the results,the accuracy of the parameters estimated from V-Gamma diagrams was sufficient to discuss the longitudinal dynamics |
