Abstract:
An analytical method for the construction of a geometric model that can be
used for numerical studies of spatial supersonic flows over complex
aerodynamic configurations is proposed. Some analytical relations for
constructing the complex geometry of bodies and a building algorithm for
isolated variable sweepback wings with parabolic profiles and flat midsurface
are given. The problem of constructing the geometry of composite
configurations of higher levels (such as a “body+wing” combination ) is
considered; an algorithm for the realization of joining the components of
this geometry is described. The problem of spatial wing flow for the
supersonic civil transport TU-144 is analyzed numerically for Mach number
$M=2.27$ and angles of attack range from 1.3 to 8.3 degrees. Our numerical
results are compared with data of physical experiments.
