<p>This study examines the landing dynamics of a reusable launch vehicle (RLV) equipped with landing legs. Using ADAMS, a commercial multi-body dynamics software, various landing simulations were conducted. The RLV's core stage and landing legs were modeled as rigid bodies with spring-dampers. Simulations were performed under different conditions, varying landing velocities (V), landing angles (<i>θ</i>_<i>L</i>), attitude angles (<i>θ</i>_<i>A</i>), and the number of landing legs. Landing success was evaluated based on predefined criteria. The study specifically focused on three- and four-leg landing configurations, analyzing the relationship between successful landings and landing velocities/angles. The maximum landing velocity for a successful landing was determined for landing angles of 0° and 5°. Additionally, for a landing velocity of 5&#xa0;m/s, the successful landing ranges for both the landing angle and core stage attitude angle were identified for each configuration.</p>
