Levitation (from Latin levitas - lightness) is the process in which an object is suspended by a physical force against gravity, in a stable position without solid physical contact. The phenomenon of levitation, caused by magnetic forces is called magnetic levitation. The main advantage of magnetic levitation systems is the elimination of friction, which significantly influences reliability, capability, ecology and safety. The phenomenon of magnetic levitation can be used in Unmanned Aerial Vehicle (UAV) catapult. The article presents the results of experiments performed on the prototype magnetic catapult. Catapult has been designed for small, unmanned aircraft, weighing less than 2 kg. The results show the oscillations of levitating cart of magnetic catapult during simulated and actual take-off and landing procedures.
