Aerodynamic Characteristics of a Delta Wing at High Angles of Attack

Abstract

any supersonic aircrafts use delta wing and they often fly at high angles of attack. For example, in landing or taking off phase, they need to fly at very high angle of attack due to their poor aerodynamic performance at low speeds. Future space plane may fly at high angle of attack even at transonic and supersonic speeds in the reentry phase. When an aircraft with delta wing flying at high angle of attack in low speeds, there appear two large counter-rotating leading edge vortices. However, when an aircraft with delta wing flies at much higher speeds, the
