Experimental and Numerical Study of Aerodynamic Characteristics for Second Generation SST 912056
Recently the programs for the development of the second generation SST are presented by several industries. On the aerodynamic design of SST, it is very important to improve a cruise L/D. So we have investigated the effects of three typical drag reduction technologies, namely, the application of a suitable wing planform, a warped wing and an area-ruled body, by using both experimental and numerical approaches. The obtained results are as follows. The increment of the cruise L/D is about 0.1 for an arrow planform, 0.6 for a warped wing and 0.5 for an area-ruled body. So we deduce that our SST configuration has the L/D of about 8.6 at cruise Mach number 2.0, including some corrections on the Reynolds number, fuselage volume, etc.. And applying our Navier-Stokes calculation code for our testing models, we find that the CFD code is very useful to predict the characteristics at design conditions
