Abstract:

The results of the calculations of the inviscid flow field behind sphere cones in hypersonic flight are presented. The flow is treated as a real gas in equilibrium in these calculations. These results show that the length of the near wake depends strongly on the main body geometry as expected. The pressure decay history along the afterbody surface is essentially independent of the afte-body shape assumed for a given main body. However, the velocity, the density, the temperature and the electron density are affected by the assumed expansion angle of the afterbody. Radially, the distributions of the flow characteristics are similar at a location sufficiently far from the base of the main body for afterbodies with the same expansion angle, but different cylindrical diameters. Furthermore, the shape of the aft portion of the bow shock is independent of the afterbody shapes assumed for a given main body under given flight conditions. Author
