Numerical Model Development of a Transformable Quadrotor.

Abstract

Unmanned Ariel vehicles are needed more and more everyday due to their ability to reach places and do tasks that are hard for human to reach and to do. Drone can face some challenges such as the short life of the battery or the environmental special conditions (obstacles, rough weather…) or just to be liberated from it six degrees of freedom. These special conditions of the drone working environment can prevent it from doing it tasks, functioning correctly or even lead to it total fail. To avoid such damages scientists and engineers had the urge to make some new kind of drones, the transformable drones. Transformable drones or reconfigurable drones are the drones that can changes their morphology In order to adapt with the external environment. We chosed the study of foldable drones more specifically horizontally rotating arms quadrotor. Using both mathematical and numerical models to represents the different configurations of the foldable quadcopter, we obtained little different results what was expected due to the use of two different models but the common things about the results is the results of both models represent steady states of the quadcopter and both model results tend to follow the pattern of the trajectory given as an input.
