“…According to the analysis results, in consistence with the previous studies [20,24], the velocity of the projectiles is proportional to the relative permeability of the projectile materials. 1050 has the highest relative permeability.…”

In this paper, the 3D model of a reluctance electromagnetic launcher was implemented using Maxwell program. The effect of the different projectile geometries was examined via the model. The projectile geometry with the highest velocity was determined. After constructing 3D model of the launcher, projectiles with different geometries were built and finally various projectiles with different geometries were analyzed. As a result, it was determined that the tubular projectile with 4 mm radius hole was the fastest among the tubular projectiles. Among the projectiles with notches, the projectile with 4 notches was launched faster than the others when the parameter was the number of notches, and the projectile with 0.5 mm notch radius was faster than the others when the parameter was the notch radius. In this paper, the highest velocity was reached the tubular projectile with 4 mm radius that was built with the 1050 material. The value of this velocity was 24.12 m/s.

“…However, our study implies both theoretically and experimentally that the maximum velocity is achieved at a projectile length that is half the coil length. Also in [15], the current applied to the coil is 1000 A whereas in our study it is 50 A. Therefore, an acceptable velocity is achieved at a significantly small current value.…”

“…FEA is a numerical analysis method that is successfully used in the analysis of engineering problems that cannot be solved or are difficult to solve by using classical methods. Therefore, 2D and 3D FEA have been used to evaluate the performance of reluctance launchers in earlier studies [10,14,15]. In this study, 2D FEA is used to analyze the proposed launcher system.…”

This paper presents the design of a 3-coil reluctance launcher system and realization of an experimental prototype. A Maxwell model of the system was constructed and finite elements analysis (FEA) was applied before building the experimental prototype. The effect of variations in projectile parameters (such as material and length of the projectile) on projectile velocity was studied using the model. Then the experimental prototype of the launcher system was built. A velocity measurement system was also designed and implemented to measure the muzzle velocity of the launched projectiles. A total of 9 projectiles of 3 different sizes made of 3 different materials were constructed to be launched by the system. Each projectile was launched via capacitors charged with DC voltage between 50 and 200 V and the muzzle velocities were measured. Finally, the effects of projectile material and projectile length on muzzle velocity and launcher efficiency were examined. In this study, an easy-to-use, low-cost, portable, and structurally simple reluctance launcher that can be operated in relatively low voltage levels was implemented. Theoretical and experimental results were compared and it is concluded that the results are consistent with each other.
