Research of novel electromagnetic catapults with many kinds of uses

We first describe the wide application of catapults, and then develop a novel electromagnetic catapult that is made up of linear brushless dc motor, describing its basic design process, analyzing various kinds of parameters of the novel linear motor, and finally using finite-element software to simulate and optimize the catapult. In addition, we also develop the test prototype machine whose length is 1 m, and it can make velocity of 6.75 kg projectile reach 10 m/s. By comparing the simulation with the experimental data, the result is satisfactory. Thus, we verify that the novel catapult is feasible further. Finally, we present the key technologies and the corresponding solution of practical application. Thus, the applied foundation has been made through the above analysis.
