چکیده

پپرنده‌های بدون سرنشین (کوادکوپتر، هگزاکوپتر، اوکتاکوپتر و غیره) می‌توانند منبع تولیدکننده سرو صدای شدید باشند. سرو صدای تولیدی زیاد این پرنده‌ها آن‌ها را برای مناطق با جمعیت بالا به ویژه در شرایط بلند شدن از زمین و فرود آمدن یا پرواز در سطوح پایین نامناسب می‌کند. این پژوهش به بررسی روش‌ها و ارائه راهکارهایی جهت کاهش یا از بین بردن سرو صدای تولیدی پهپادها می‌پردازد. برای کاهش سرو صدای تولیدی هر دو روش فعال و غیرفعال در نظر گرفته شده است. راهکارهایی همچون صدا خفه‌کن برای موتورهای پیستونی، پروانه از نوع Q-tip، افزایش تعداد پره‌های پروانه، مرزهای جاذب و بازتاب‌دهنده، پره‌های داکت شده، داکت‌های جاذب صوت، همگام سازی، کاهش نویز چند کاناله فعال به همراه سیستم ثانویه تعبیه شده به صورت مدور در اطراف پروانه و سیستم‌های با پروانه‌های مغناطیسی معرفی شده‌اند.
