Abstract
This study investigates the ِِgeometrical solution for a given pressure (i.e. velocity) distribution of subsonic flow around an aerofoil section using an analytical method. The results show that the analytical method is not precise on the leading edge, when it is used to solve the mean camber line of updated profile RAE (Royal Aircraft Establishment). Therefore, a correction parameter with changeable values ranging between 0.32 and 0.42 was created, and it gives appropriate results

مسألة تحديد أبعاد الشكل الهندسي لمقطع الجناح بمعرفة طبيعة توزيع الضغط (أو السرعة) تمت معالجتها باستخدام الطريقة التحليلية لجريان هوائي ثنائي البعد اقل من سرعة الصوت حول الجناح. أظهرت النتائج أن الطريقة التحليلية لا تعطي نتائج صحيحة لمقدمة الجناح عند إجراؤها على نوع RAE (Royal Aircraft Establishment) لذا في هذا البحث تم استحداث معامل تصحيح له قيم متغيرة تتراوح بين 0.32 -0.42 يمكن من إيجاد نتائج دقيقة عند الإجراء التحليلي على هذا النوع من المقاطع.
