Abstract: One of the important tasks in designing and optimizing the landing process of an unmanned aircraft is to accurately determine the impact loads during the landing event. On the nose leg with a separate rubber shock absorber, a variant of oleo-pneumatic shock absorbers is subsequently incorporated into the existing connection points. On a special device for dynamic testing of landing gear of unmanned aircrafts and very light aircrafts, tests were carried out on the nose landing gear. This paper examines the results of dynamic testing of the reception of the ground energy of the nose landing gear of the unmanned mid - range aircraft.

Keywords: UAV Pegasus, landing process, nose landing gear, impact loads, energy dissipation.
