Description

VFP is a CFD (computational fluid dynamics) method coded in
FORTRAN for calculating the flow field and aerodynamic forces of an
isolated wing (denoted usually as a wing-alone) or a wing-body
combination (denoted usually as a wing-body) in a subsonic
freestream, including the effects of shock waves and boundary
layers. VFP uses a relaxation process to solve finite-difference
forms of the full nonlinear velocity-potential equation for the
flow around the three-dimensional geometry. The viscous effects are
modelled using a coupled semi-inverse swept tapered integral
boundary-layer method. The VFP program was developed over a period
of years at ARA, Bedford and RAE/DERA (now QinetiQ), Farnborough,
and is made available by ESDU under the terms of an agreement with
QinetiQ. Used originally on mainframe computers, VFP has provided
valuable data in the design of a number of aircraft. With advances
in computers, it has become possible to perform runs of VFP on a PC
within a few minutes. One of the advantages of the VFP method is to
provide a rapid process to produce valuable data to assess the
aerodynamic qualities of wings as part of the design process.
