Abstract
The parameters and procedures that can be used to optimise the multistage reluctance accelerator were explored in this study. The initial provided voltage, the projectile's form, the
projectile's initial beginning position, the reluctance accelerator’s number of stages, and the projectile's degrees are all variables in this experiment that affect the projectile's speed and the reluctance accelerator’s efficiency. All of the trials were carried out with a speed sensor to collect data on the projectile's speed in order to determine the best reluctance accelerator. The reluctance accelerator’s magnetic field and flux density were studied using FEMM modelling software to determine and calculate the theoretical value. The simulation result was then compared to the experiment result in order to determine the theoretical and real-world disparities. From this experiment, it was discovered that a three-stage reluctance accelerator operating at 200V had a maximum value efficiency of 4.49 %. For a ten-stage accelerator, the starting point that results in a maximum velocity of 48.57 m/s was discovered to be 7.5 mm with 250V. The projectile's form parameter achieved the greatest velocity of 25.2 m/s when it was flat and at a location of 7.5 mm with 250V using three-stage reluctance accelerator. The projectile's degree achieved the greatest velocity of 22.2 m/s when it was 30 Degrees and at a location of 7.5 mm with 250V using three-stage reluctance accelerator. According to what was test, using a more advanced reluctance accelerator with a higher starting voltage supply, a projectile that was slightly positioned within the coil allowed for the projectile's maximum speed and reluctance accelerator efficiency.
