小型变体无人机动力学建模及配平分析
Dynamics Modeling and Trimming Analysis for Small Morphing UAV
摘要
Abstract
In order to better analyze the dynamic response of morphing Unmanned Aerial Vehicle (UAV),the moving of the center of gravity is described by quiet moment,and the six free nonlinear equations of motion for a small variable sweep UAV is derived.The kinematic equation of morphing aircraft has more items that are inertial force and inertial moment than fixed wing plane.The aerodynamicforces and moments in the process of morphing are calculated with the quasi-steady assumption,the aerodynamic force is depended on the static configuration and flight state of morphing aircraft at the moment of morphing.From the results it can be known that the main variable that affects the aerodynamic parameters ie sweep angle and angle of attack within a certain range of flight speed and altitude.To make sure that the morphing aircraft has an ideal static stability margin,the responsible position of the center of gravity on the longitudinal axis of the body at different configurations is obtained by trimming,which lays a foundation for the control system design for the morphing aircraft.关键词
