Popis: The launchers directorate of CNES has initiated a project to develop a multicopter and to use it as a test-bench for launchers problematic investigations and to test Guidance, Navigation and Flight Control algorithms. For Flight Control, propellants sloshing are modelled with equivalent pendulums. A device composed by a tank where the liquid can be replaced by its equivalent pendulum was designed. The multicopter with the device was forced to oscillate around one axis to study the oscillations responses of the full system for both configurations. This paper presents the vehicle and the device. First experimental results are analyzed.
