Modern sea operations used for exploration and reconnaissance purposes are becoming more and more dependent on unmanned air vehicles (UAV). With the development of an increasing number of UAVs directed to the needs of the navy, various take-off and landing systems are being tested. An alternative to the traditionally used catapults is magnetic catapults, which enable continuous power control, properly increasing the acceleration of the starting machine and at the same time enabling full automation of the launching process. The paper presents the developed of the physical model and theoretical analyzes the forces and torques acting on the launcher system using passive magnetic suspensions with high-temperature superconductors. The launcher was modeled as a configuration of three elements: tracks built from neodymium magnets generating the magnetic field, a starting cart driven by a linear engine and a UAV taking off or landing on the launcher cart. The set of assumptions regarding the characteristics of the environment, the structure of the system elements, kinematic constraints were made. The article consists also the theoretical analysis of external interactions having a decisive influence on the dynamics of the system. The analysis considers the couplings resulting from mutual interactions of individual elements of the system. Theoretical considerations were supplemented with a comparative analysis of numerical and experimental studies of the UAV launch process from the launcher which allowed the verification of the key parameters of the analyzed forces.
