PRELIMINARY DETERMINATION OF THE JET-2 UNMANNED AERIAL VEHICLE DYNAMIC PERFORMANCES

The paper presents result of theoretical analysis of the spatial dynamic performances for an unmanned aerial vehicle (UAV). This drone is designed and produced by consortium consisted of The Air Force Institute of Technology, The Military University of Technology, The Warsaw University of Technology and The MSP enterprise. A plane JET-2 is the jet-powered airplane dedicated for Polish Military Forces. It will be used in the training process of anti-aircraft crews. Because of high level of requirements (maximum speed, stall speed, climb rate, range and endurance), it has been designed as the jet-powered aircraft. This plane will perform autonomous flights and therefore it should be stable in all phases of flight – static and dynamic stability is desirable. Therefore, the theoretical analysis focused on the stability performances have been performed, parallel to laboratory tests. They were done using nonlinear mathematical model of the JET-2. This model will be described in the paper as well as selected results of numerical simulations. The UAV JET-1 parameters and main parts of the system with the performances as the take-off mass 80 kg, the maximum speed 150 m/s, the endurance 60 min, the altitude 5000 m are presented in the paper.
