The thesis adresses the problem of devices for catapulting and capturing of the light unmanned areal vehicle ScanEagle and proposes the concept of a launcher-retrieval device that serves as a solution. The thesis encompasses the review of the existing system and exposes the disadvantages of using two separate devices and the problems of the retrieval mechanism. The review and analysis of all most commonly used catapulting systems and mechanisms for retrieval of aircraft follows. Every catapult system is supported with mathematical and physical explanations and derived equations. Based on the comparison of systems, the spring system is chosen as it is, according to our parameters, the most effective mechanism, since we can launch and retrieve aircraft with it.
