Mathematical model of UAV in numerical simulation of the recovery manoeuvre in a perturbed flight

Mariusz Krawczyk, Jerzy Graffstein, Jerzy Maryniak
The study presents a mathematical model in terms of the Boltzmann-Hamel equations representing a controlled Unmanned Aerial Vehicle (UAV) motion. The widely known problems with takeoff and recovery manoeuvres of UAV are considered. Both manoeuvres are characterised by low velocities, large angles of attack and relatively low efficiency of the control, so the sophisticated procedures are then necessary to ensure flight safe during these phases of motion. Some results of the first phase of recovery manoeuvre numerical simulations are reported.
