             abstract = "This work describes a computational investigation on rarefied 
                         hypersonic flow past truncated wedges at incidence. Positive 
                         angle-of-attack effects on the flowfield structure have been 
                         investigated by employing the Direct Simulation Monte Carlo 
                         Method. A method that properly accounts for the nonequilibrium 
                         aspects of the flow. Aspects that arise near the leading-edge nose 
                         and that are especially important at high Mach numbers. The 
                         results presented highlight the sensitivity of the primary 
                         properties to changes not only on the angle of attack but also on 
                         the frontal-face thickness of the leading edges. Some significant 
                         differences between sharp and blunt leading edges were noted on 
                         the flowfield structure. It was found that the angle-of-attack 
                         variations have different influence on velocity, density, pressure 
                         and temperature along the stagnation streamline ahead of the 
                         leading edges as well as on the profiles adjacent to the body 
                         surface. The analysis showed that positive angle of attack causes 
                         the expected asymmetry in the flow patterns as the stagnation 
                         point moves from the symmetry axis to the windward side of the 
                         leading edges. Interesting features observed in the properties 
                         profiles showed that small leading edge thickness, compared to the 
                         freestream mean free path, still has important effects on high 
                         Mach number leading edge flows.",
