    Opis:
    This paper contains the design of a testing device, which was constructed for the purposes of checking functional properties of the innovative solutions of variants of electromagnetic locking devices with potentials of replacing current mechanical brakes used for stopping pallets with loaded cars in parking houses developed by the company KOMA - Industry s.r.o. The testing device consists of two positioning tables, whose moveable parts are anchored perpendicular to each other in the frame of the testing device. An electromagnet and a solenoid generating the force needed for stopping the motion of the pallet is connected to the moveable part of the upright positioning table. The brake ramp made of a ferromagnetic material has a hole at its top surface into which the pin of the solenoid is inserted and is attached to the horizontal moveable part of the positioning table. This paper presents holding force values of the electromagnet, which were obtained by experimental measuring on the created testing unit.

    Opis:
    UAVs in recent times have achieved an increased rate of development, and hence, can cover a large spectrum of missions. Based on the dimensions, we can find UAVs from large dimensions used to operate at the global level through mini UAVs used inside buildings. The large UAVs are operated almost like a manned aircraft. For this reason, it uses the airport infrastructure and a runway for take-off and landing. The mini UAVs can be launched by hand. Between these two extremes, there is a category of UAVs used at the tactical level, which cannot be launched by hand and is not possible to build a runaway. These UAVs are launched using RATO (rocket-assisted take-off) or catapults. To improve the launch system, this should have a few moving parts to reduce maintenance costs and be powered by electric energy to be easily integrated into the automatic control loop. This paper presents a new design of a launch catapult based on electromagnetic energy for tactical UAVs. This technology is under development to launch projectiles with high velocity; however, it has theoretically proved the possibility to equally launch UAVs. The second part presents the theoretical approach necessary to find the expression of force under certain approximation for electromagnetic launch system design.

    Opis:
    The paper analyses a new configuration of an electromagnetic launch system (EMLS) able to accelerate a 1-kg mass projectile at a muzzle velocity of 3,000 m/s with an acceleration length of 10 m. The analyses consist of a mathematical calculation of the value of acceleration force necessary to achieve the project objectives. Based on these results a new configuration of an EMLS is presented. The projectile is accelerated by the Lorentz force where the magnetic field is created by permanent magnets made of neodymium iron boron (NdFeB). The permanent magnets are arranged in a cylindrical Halbach array with a uniform field inside. The copper wire coils have a special design, which produce a large acceleration Lorentz force with a current under 1,000 A. A short comparative0 analysis shows the advantages of this new solution compared with well-known accelerators such as railguns and coilguns. In the next part of the paper, we present the results of a simulation of this configuration with an interactive software package based on the finite element method used to analyse and solve three-dimensional electromagnetic field problems and simulate the movement of the projectile. These results confirm the advantages of this new configuration and open the way to test the system under laboratory conditions. At the end of the paper, conclusions are presented. This new EMLS, based on Halbach array configuration, can be used as a catapult for UAVs, airplanes or missiles, as a mass driver for small satellites or as a gun, which is a better solution than railguns or coilguns.
