Abstract AR
زيادة الكفاءة الأيروديناميكية مع ضمان المناورة الخارقة للطائرة ذات السرعة فوق الصوتية (F-16A) يتم تقديمها.
الخواص الأيروديناميكية، توزيع الضغط على سطح الطائرة و أعلى رفع يتم حسابه للشكل الرئيسي للطائرة لأعداد ماخ و زوايا هجوم مختلفة في حالة الطيران تحت وفوق الصوتي، باستخدام طريقة الأشرطة (Panel Method) و المعادلات شبه التجريبية (DATCOM).
تم بناء برنامج حاسوبي فرض فيه آلية الدفع الموجه (TVFC) مع أسطح السيطرة (Canards)، النتائج بينت أن أسطح السيطرة مع آلية الدفع الموجه قد ولدت عزم ترجح (Nose-down pitching moment) يستطيع إسناد الذيل الأفقي في حالة المناورات العالية.
أما من الناحية الأيروديناميكية فأن (5-6 %) زيادة في الكفاءة الأيروديناميكية وجدت بعد إضافة أسطح السيطرة عن الشكل الأصلي للطائرة في حالة الطيران تحت و فوق الصوتي.
Abstract EN
Increasing the aerodynamic efficiency and enhancing the super maneuverability for the selected supersonic aircraft (F-16A) is presented.
Aerodynamic characteristics, surface pressure distribution and maximum lift are are estimated for the baseline configuration for different Mach number and angles of attack in subsonic and supersonic potential flow, using a low order three-dimensional panel method supported with semi-empirical formulas of Dotcom.
Estimation of the total nose-up and nose-down pitching moments about the center of gravity of the completed aircraft in subsonic region depending on the flight conditions and aircraft performance limitations.
A modern program was implemented by suggesting a two dimensional thrust vectoring technique (pitch vectoring up and down) controlled by the best design of advanced aerodynamic and control surface (fore plane or canard).
Work results shows that the canard (as a control surface) with thrust vectoring produces enough nose-down moment and can support the tabulator at high maneuvers, while for an aerodynamic surface, a rate of (5-6 %) increase was achieved in the aerodynamic efficiency (lift-to-drag ratio) of the baseline configuration in both subsonic and supersonic flight.
