هدف از این تحقیق بهبود عملکرد آیرودینامیکی ایرفویل ناکا-23012 مجهز به ابزار برآافزای لبه فرار با تغییر در یکی از مهم‌ترین پارامترهای هندسی آن می‌باشد. در این تحقیق حل معادلات ناویراستوکس در شرایط جریان آشفته و تراکم‌ناپذیر با بهره‌گیری از نرم‌افزار فلوئنت صورت پذیرفته است. بعد از فرآیند مدل‌سازی ایرفویل و فلپ، در زوایای فلپ متفاوت(10 الی 30 درجه)، شبکه‌بندی بی‌سازمان در نرم‌افزار گمبیت تولید شد و بهبود عملکرد آیرودینامیکی ناشی از تغییر در پارامتر هندسی لبه شکاف مورد بررسی قرار گرفت. جریان از نوع دائم، آشفته و تراکم‌ناپذیر فرض شده و الگوریتم حل معادلات نیز فشار مبنا انتخاب شده است. محدوده عدد رینولدز جریان106×6/3 بوده و مدل آشفتگی مورد استفاده کا-اپسیلون در نظر گرفته شده است. مقایسه نتایج و مشخصه‌های آیرودینامیکی ایرفویل مجهز به فلپ تک‌شکافه پس از ایجاد تغییر موردنظر در پارامتر هندسی، نشان می‌دهد که با بهبود قابل توجه ضرایب آیرودینامیکی(به طور میانگین افزایش 9 درصدی ضریب برآ و نیز افزایش 6 درصدی ضریب پسا)، باند فرود هواپیما کاهش خواهد یافت. هم‌چنین بررسی گرادیان‌های فشار و سرعت در مقاطع مختلف، نشان می‌دهند که تغییر به وجود آمده موثر بوده و در مقایسه با مقاله مرجع توزیع بهتری صورت پذیرفته است.
