                         leading edges situated in a hypersonic flow. The primary aim of 
                         this paper is to examine the effect of rarefaction on the 
                         aerodynamic surface quantities. Rarefaction effect on the 
                         aerodynamic surface quantities has been investigated by employing 
                         the Direct Simulation Monte Carlo (DSMC) method. The work is 
                         motivated by interest in investigating power-law shaped leading 
                         edges as possible candidates for blunting geometry of hypersonic 
                         leading edges. The sensitivity of aerodynamic heating and drag to 
                         variations on rarefaction are simulated for altitudes of 70, 80 
                         and 85km. The analysis shows significant differences on the 
                         aerodynamic heating and drag due to variations not only on the 
                         altitude but also on the leading-shape defined by the power-law 
                         exponent. It was found that the heat transfer and drag 
                         coefficients increase with increasing the altitude.",
