AERODYNAMIC BODY SHAPING METHOD FOR A STEALTH FIGHTER AIRCRAFT

摘要

In the field of aviation the size and shape of the aircraft plays a vital role in determining aerodynamic performance. Shaping is a very important factor for achieving air worthiness parameters such as lift, drag, speed and also for cost considerations. Effective size of complex shape such as an aircraft can be measured by determining its Radar Cross Section (RCS). RCS is the size of the target as seen by the radar. For military applications the interest is in making an object's RCS small so as to make it difficult to identify military targets such as missiles, tanks, ships and aircrafts. The RCS reduction technique by aerodynamic body shaping is one of the basic methods of RCS reduction technology to achieve stealth. In other words stealth technology can be termed as RCS Reduction Technology.
