The metamaterials have been studied and pointed as the future of many engineering areas, such as
mechanical, aeronautical, civil and electrical. A metamaterial structure differs from another due to the geometry
of the unit cell, which provides unique physical properties. Among those properties, it is found the high capacity
to absorb and mitigate impact loads. It was verified the viability of applying an origami structure in a landing gear
for the Microsatellites Launch Vehicle (VLM-1), the binational project between Brazil and Germany, aiming to
recover its first stage. The dynamic response of that structure is compared to a classical structure and the reaction
force in the connection between the vehicle and the landing gear is mainly analyzed. The verification was carried
out numerically, though impact analysis simulated in the commercial software ANSYS®. The results reveal that the
studied application is feasible, attenuating the force reaction in the extremities of the leg in contact with the vehicle.
