Aerodynamic characteristics of a hypersonic viscous optimized waverider at high altitudes

RETRACTED: Thermal protection mechanism of heat pipe in leading edge under hypersonic conditions

“…1,2 Due to a series of outstanding advantages of superior maneuverability, high level of survivability and excellent global strike capability, it has become a major research field in aeronautics and astronautics worldwide. [3][4][5] In order to reduce aerodynamic resistance, an extremely sharp wing leading edge is required and a radius with a magnitude of millimeters is commonly employed.…”

Effects of compressibility on aerodynamic surface quantities over low-density hypersonic wedge flow

“…Based on recent interest in hypersonic waveriders for highaltitude/low-density applications (Anderson, 1990, Potter and Rockaway, 1994, Rault, 1994, Graves and Argrow, 2001and Shvets et al, 2005, this work extends the analysis presented by Santos (2002 and2005). In an effort to obtain further insight into the nature of the flowfield structure of truncated leading edges under hypersonic transition flow conditions, a parametric study is performed on these leading edges with a great deal of emphasis placed on the compressibility effects.…”

Physical and computational aspects of shock waves over power-law leading edges

“…Based on recent interest in hypersonic waveriders for high-altitude/low-density applications, [25][26][27][28][29] this paper extends the analysis presented by Santos and Lewis 17 by computationally investigating the shock-wave structure over power-law leading edges by employing a procedure based on the physics of the particles. In this scenario, the primary goal is to assess the sensitivity of the shock-wave standoff distance, shock-wave thickness, and shock-wave shape to variations on the leading-edge shape and to compare them to the round shape ͑circular cylinder͒.…”
