“…Since the 70's of the last century, the transport of men and payload to space by EM launcher is an ongoing topic in the community (Bolonkin and Krinker 2010;Fair et al 1989;Meinel 2007). Currently, a scientific collaboration of American institutions is working on a railgun system able to accelerate nanosatellites to space from an airborne platform (McNab 2007;Wetz et al 2009). Other scientists prefer a hybrid system of a conventional rocket, pre-accelerated by a railgun (Božić et al 2010;Schneider et al 2011).…”

“…The need for motion control, repeatability of startup parameters, protection against overloads and operator safety has numerous researchers working, in Poland as well as abroad, on controlled launcher design. The investigation of electrically powered devices has been particularly popular and has been considered both in the past [10][11][12] as well today [13][14][15][16][17], even concerning for UAVs of a few hundred kilograms weight [18]. A prototype of a synchronous magnetic launcher for MAVs having a mass up to 2 kg has been developed at the BUT [8,[19][20][21] with research into a similar prototype for aircraft weighing 10, 20 and 25 kg also initiated [22].…”

Assisting in the starting procedure of Unmanned Aerial Vehicles (UAVs) is one of many very important areas of modern aviation research. Supported start-up saves fuel or electrical energy, increases operator safety and level of autonomy, extends the application area, and, in some applications, even enables the operator to shape the motion characteristics of the initial phase of a UAV’s flight. Currently used solutions, depending on an aircraft’s class, are based on the utilization of rubber, pneumatic or electromagnetic launchers. All of these launchers are used for the medium class of UAVs and all of them use the potential energy previously stored in stretched rubber, compressed air or electrical voltage. In this paper, authors propose the novel concept of a launcher powered through kinetic energy stored in a rotary wheel driven by an electric motor. Using the transmission systems of the drive and the controlled clutch and an electromagnetic brake, it is possible to precisely control the speed and acceleration of the launched object. Within the paper, the authors present and discuss the applied equations of dynamics, the results of a simulation that was carried out using the MATLAB/Simulink software and a conceptual CAD model of preliminary engineering solutions for the kinetic UAV launcher. The work is summarized in the conclusions section, which details the practical implementation of the device.

“…The idea of application of magnetic technology for aircraft launch is not new. Interesting papers concerning such topics have been already published (Patterson et al, 2002;McNab, 2007). Among others, very innovative research was carried out on electromagnetic launch systems for large airplanes.…”

The paper presents a concept of a magnetic coil launcher for unmanned aerial vehicles of mass up to 25 kg. The idea is not new, nevertheless in the paper, an innovative application of magnetic launcher technology for selected class of unmanned aerial vehicles is presented. So far, at Bialystok University of Technology, a magnetic coil launcher for micro aerial vehicles of mass up to 2.5 kg has been investigated. In the article, simulations of a conceptual multi-coil launcher with a magnetic core system are presented. The finite element method has been used in calculations. Moreover, in the paper, the concept of a magnetic support for transmission of mechanical power from the magnetic core to the launched payload is proposed. The applied methodology, computational results and potential technical difficulties of practical applications are also widely discussed.
