Abstract

© 2017, Springer International Publishing AG.Supersonic flight has been the subject of last half century. Both civil and defence projects have been running to design an aircraft to fly faster than speed of sound. Developing technology and increasing experience of design leads to faster, fuel efficient, hence, ecological, long-ranged aircrafts. These vehicles make people live easy by shortening travel time, perform missions with powerful defence aircrafts and helping explore space. Aerodynamic design is the main argument of the high speed aircrafts improvement. Having less supersonic drag force, which is greater than the double of subsonic case for conventional aircraft, is the ultimate goal of the aircraft designers at supersonic speed. In this chapter, an aerodynamic characteristics of the entire configuration is optimized in order to reach this aim. Moreover, solver algorithm is validated with computational fluid dynamics simulations for different geometries at various speeds. The objective of this study is to develop a program which optimizes wave drag coefficient of high speed aircrafts by numerical methods.
