Concept of the magnetic launcher for medium class unmanned aerial vehicles designed on the basis of numerical calculations

Abstract

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.

Süperiletken Manyetik Yataklı Doğrusal Fırlatıcı Sisteminin Ray Konfigürasyonun H-Formülü Yöntemi ile Tasarlanması

“…Dolayısı ile motora uygulanan geri beslemeli kontrol sayesinde daha kontrollü hava aracı kalkışları yapılabilmekte ve klasik yönteme nazaran hava aracı gövdesine zarar verme olasılıkları minimize edilmektedir. Elektromanyetik fırlatıcıların bir diğer avantajı ise klasik sistemlere göre daha az yer kaplaması ve operasyonel maliyetlerinin daha düşük olmasıdır (Kondratiuk ve Ambroziak, 2016;Reck, 2003). Elektromanyetik fırlatıcılar, hava aracını fırlatmak için bir pist boyunca bir vagonu iten elektrik akımı ile çalışan doğrusal bir endüksiyon motorunu (linear induction motor) kullanırlar.…”

Design and Dynamics of Kinetic Launcher for Unmanned Aerial Vehicles

“…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]. Today, the main technical problem associated with launchers for UAVs is the accumulation of energy.…”
