comparison, these calculations were also done using the Aerodynamic Preliminary
Analysis System (APAS)8 and the APAS-results are included in Figs. 3.60 and 3.61.
  The APAS is an interactive, graphic user interface program for preliminary
aerodynamic analyses of airplane-type configurations.lt uses slender body theory
for subsonic/supersonic modeling of the fuselage. The surface singularity/panel
methods are used for wing and tail surfaces at subsonic/supersonic speeds. The
interference effects between fuselage ancl wing and between fuselage and tail
surfaces are modeled using a cylindricalinterference shell enveloping the fuselage.
The analysis for subsonic/supersonic Mach numbers is performed by the unified
distributed panel (UDP) program. For hypersoruc Mach numbers, APAS uses the
hypersonic arbitrary body program (HABP).
