| چکیده | ||
| شناور تندرو از جمله سازه‌‌های دریایی است که دارای طراحی پیچیده می‌باشد. پایداری و سرعت دو فاکتور مهم در ساخت شناور تندرو است. جذابیت و پیچیدگی این نوع شناور باعث شده است، محققین بسیاری در این زمینه فعالیت کنند. در این مقاله به بررسی تجربی تاثیر ودج بر روی پایداری و مقاومت شناور تندرو تک بدنه پرداخته شده است. شناور مورد بررسی دارای ددرایز ثابت بوده و نسبت صول به عرض آن 4.8 می‌باشد. تست‌ها در اعداد فرود عرضی 0.1 الی 4.26 در آزمایشگاه ملی دریایی خلیج فارس انجام شده است. پارامترهای اندازه‌گیری به ترتیب تریم، رایزآپ، مقاومت، طول خیس چاین و کیل می‌باشد. شناور در سرعت 8 متر بر ثانیه ناپایدار می‌شود. برای پایدار شدن شناور از یک ودج استفاده می‌شود که دارای ارتفاع 5 و طول 92 ملیمتر می باشد. مقاومت شناور در این حالت کمتر می‌شود و پروپویزینگ شناور از بین می‌رود.ی ی ی ی ی ی | ||

| چکیده [English] | ||
| High speed craft is one of the most sophisticated marine vehicles. Stability and speed are two important factors in the construction of planing hulls. The attractiveness and complexity of this type of vessel has led many researchers to work in this field. In the current paper, the effect of wedge on the stability and resistance of a mono-hull high speed craft is experimentally investigated. The studied vessel has a constant deadrise angle and the length to width ratio is 4.8. The tests were conducted at transverse Froude numbers of 0.1 - 4.26 at the National Iranian Marine Laboratory. The measured parameters are trim, rise up, resistance and the wetted length of chine and keel. The vessel at the speed of 8 m/s was unstable. To stabilize the vessel, a wedge with a height of 5 mm and a length of 92 mm has been used. In this case, in addition to the absence of porpoing, the resistance of the vessel, decreases. | ||
