چکیده

امروزه مطالعه و تحقیق بر روی مدل‌سازی، شبیه‌سازی، ساخت و بهبود عملکرد پرتابگرهای الکترومغناطیسی، یکی از زمینه‌های اصلی تحقیقات بسیاری از دانشگاه‌ها و مراکز پژوهشی دنیاست. کاربردهای فراوان پرتابگرها در حوزه نظامی، هوا فضا و جنگهای هوایی است. . در این مقاله، مشخصات نمونه ساخته شده، مدل‌سازی، شبیه‌سازی و نتایج آزمایش نمونه آزمایشگاهی پرتابگر ریلی با قدرت 2/2 کیلو ژول گزارش شده است. در مدل انتخاب شده، مقادیر جریان ریل، شتاب، سرعت، موقعیت، نیروی وارده بر پرتابه، راندمان پرتابگر با استفاده از نرم افزار MATLAB شبیه‌سازی و نمایش داده می‌شود. پس از ساخت و تست نهایی پرتابگر، سرعت خروج پرتابه از دهانه پرتابگر، شدت جریان تخلیه بانک خازنی به ترتیب با استفاده از یک حسگر مادون قرمز و یک سیم پیچ روگوفسکی اندازه‌گیری می‌شود. سرعت خروج پرتابه از دهانه پرتابگر ریلی به بیش از m/s100 می رسد. در انتها این اندازه‌ها با مقادیر مشابه شبیه‌سازی مقایسه می‌گردد. آثار تخریبی پلاسمای ایجاد شده در ریل ها قابل توجه است.

چکیده [English]

Nowadays, research on modeling, simulation, construction, performance improvements of electromagnetic launchers is one of the main areas of research in many university and research centers in the World. In this paper, we are reporting how to making, modeling, simulation and fabrication of a prototype rail-gun with 2.2 kJ pulse power supply. In the choose model simulated current of rails, acceleration, velocity, position, exerted forces on projectile and efficiency of launcher by MATLAB codes. After fabrication and final testing of launcher, current of capacitive bank and muzzle velocity of projectile is measured by Rogowski coil and infrared sensors respectively. At the end, these values are compared with similar values in simulation.
