چکیده

در این تحقیق، تأثیر دامنۀ بال‌زنی یک بال‌زن، هم‌زمان با اثر انعطاف پذیری بال، بر عملکرد آیرودینامیکی آن، بررسی شده است. برای این هدف، یک مکانیزم بال‌زن با بال پوسته‌ای انعطاف‌پذیر و یک سامانۀ اندازه‌گیری نیروی پیشران طراحی و ساخته شد. در این آزمایش‌ها، در گستره‌ای از فرکانس‌ها و دامنه های بال‌زنی برای دو نمونه بال با انعطاف پذیری متفاوت از نظر خمشی و پیچشی، نیروی پیشران تولیدی و توان مصرفی اندازه گیری شده است. نتایج نشان می دهد با افزایش دامنۀ بال‌زنی، میزان نیروی پیشران تولیدی، افزایش می یابد، که البته برای دو پوستۀ بال با ضخامت مختلف متفاوت است.

چکیده [English]

In this research, the flapping amplitude effect and flexible shell on the MAV (Micro Air Vehicle) aerodynamic performance in hovering flight are experimentally investigated. For this purpose, a flapping membrane wing mechanism and an experimental measurement setup for measuring generated thrust were designed and constructed. In these tests, for two wings with different flexibility, generated thrust and power usage were measured in the range of flapping frequency and amplitude. In general, flapping wing generated thrust increases with raising flapping amplitude. Values of the propulsion force are different for these two wings.
