The document discusses kinematics analysis of an aerodynamic model for a quadcopter UAV. It introduces the increasing importance of UAVs and the need to research their kinematic characteristics. The analysis includes simulating flight tracks, developing guidelines and validation techniques through simulation. The aerodynamic module calculates thrust and torque from propeller deflection and feeds results into the flight dynamics equation module to model the quadcopter's kinematics.

Kinematics analysis of Aerodynamic Model
Quad copter quadrotor unmanned aerial vehicle (UAV) helicopter is used as a search and rescue field robot. The UAV is getting more and more important with its increasing demand in war, now each country pays more attention to researching work of UAV, includes the early researching project, hardware simulation, performance validation, and simulation training. The researching work of kinematics characteristic is the basic work of the UAV system. The research work includes the simulation of flight track, guideline about and related techniques the validation work through the simulation operation. INTRODUCTION
Aerodynamic Characteristic Analysis The primary module includes tele control and remote sensing modules, aerodynamic model, power equipment modules (includes engine model and propeller model), task equipment module and scene module. Aerodynamic module calculates the propellers thrust and torque according to deflection of the rudder, and then the calculation results are put into flight dynamic equation module
Calculation process of the kinematics equation
Mathematical modelling of Quadcopter Kinematics is a branch of mechanics which studies the motion of a body or a system of bodies without consideration of the forces and torques acting on it. To describe the motion of a 6 DOF rigid body it is usual to define two reference frames [33]: Earth inertial reference (E-frame)
Body-fixed reference(B-frame) Linear velocity Angular velocity Rotation matrix
Transfer matrix The derivative of the generalized position in the earth frame
The Structure Model in Hovering condition
basic movements of quad copter Throttle Roll
Pitch Yaw
Conclusion We study on 6 degrees of freedom aerodynamic model. we can use mathematical simulation method to check flight characteristic of UAV.
