INTRODUCTION<\/strong><\/p>\n

This is the fifth part of the series of Data Items dealing with
\nthe Full-Potential (FP) method for three-dimensional wings and
\nwing-body combinations. There is a facility in FP for using an
\nindirect (albeit approximate) method of including the effects on
\nthe wing due to the fore and aft shaping of the fuselage. Using
\nthis approach, the fuselage is specified in the geometry file as an
\ninfinite circular cylinder with a radius which closely represents
\nthe fuselage cross section profile at the wing-body junction, but
\nthe effective flow speed at each wing spanwise grid position
\ndiffers from the actual free stream Mach number. The speed
\ndifferences that are applied in FP are derived from input values of
\nincrements to the free stream Mach number. The Mach number
\nincrements are specified in the flow input file at a number of
\nlateral locations to give a spanwise variation. The FP program then
\nutilises linear interpolation (and, if necessary, linear
\nextrapolation) to generate the corresponding increment at each of
\nthe wing grid sections.<\/p>\n

Alternatively, as described in ESDU 02013 (Reference 1), the
\nMach number increments may be determined by a body-alone method
\nsuch as slender-body theory or a panel method. This Data Item
\ndescribes a simple procedure for implementing the effects of body
\nshaping at zero incidence by means of the \u2018source-sink'
\nrepresentation to provide a pre-processor to FP to routinely
\ncalculate the effects of body shaping based solely on body length,
\nfore-body length, aft-body length, body radius of the parallel
\nportion and wing position.<\/p>\n

A detailed description of the use of the pre-processor programs
\nis given in Section 3 followed in Section 4 by a process to output
\ndata in a format giving contours of constant Mach number. The
\nprinciples of the method are given in Section 5. Comments on the
\naccuracy and limitations are in Section 6. The derivation of body
\nshape process and validation of the method is given in Appendix
\nA.<\/p>\n","protected":false},"excerpt":{"rendered":"
