             abstract = "ABSTRACT: The successful design of high-lift, low-drag hypersonic 
                         configurations depends on the ability to incorporate sharp/blunt 
                         leading edges that combine good aerodynamic properties with 
                         acceptable heating rates. In this study, the hypersonic 
                         two-dimensional flow around a family of flat-nose leading edges at 
                         zero incidence is investigated by using the Direct Simulation 
                         Monte Carlo (DSMC) method. Effects of variation on the body 
                         surface temperature and on the leading edge thickness are 
                         investigated in terms of the aerodynamic surface quantities. The 
                         aerothermodynamic performance of the flat-nose leading edges is 
                         assessed by using the pressure, skin friction, heat transfer and 
                         total drag coefficients. The calculation results depict a weak 
                         effect of the leading edge thickness and of the wall temperature 
                         on total drag, while predict a strong dependence of stagnation 
                         point heating on the leading edge thickness over the range 
                         examined. The data generated in the present study is part of an 
                         investigation in order to determine the benefits and disadvantages 
                         of using these new blunt shapes over circular cylinder shapes.",
