VSP User Manual

Version 1.7.92
Section ID:
Choose a section with which to work. The section chosen will be highlighted
with a red box on the main screen. New sections may be added as needed: However,
note that new sections will be added to the right of the currently selected section.
Number Interpolated Cross Sections (Num Interpolated XSecs)
Section (Sect):
Increasing the number increases the amount of sections in the part
selected. However, increasing the number of sections on slow computers will have a
detrimental effect on the performance of VSP.
All:
Clicking on the arrows on either side of this field increases or decreases the number
of sections in every part of the wing.
Section Planform
Driver:
From this list, the user may choose three out of the six parameters to define the
specific wing section.
The user must select which of the six slider bars become available. For instance,
selecting Span-TC-RC will allow the user to change the Span, Tip Chord (TC), and Root
Chord (RC) sliders (just below the Driver drop-down box), but will not allow them to
change the Aspect Ratio (AR), Taper Ratio (TR), and Area sliders.
Note
: There is no way to have all six sliders active at the same time. This
is because VSP is parametric, and changing the characteristics of the
active set of drivers will by necessity change the inactive set in some
fashion.
Sweep and Twist:
Choose any angle from -85 to 85 degrees for the specific section.
Also, the sweep or twist location can be chosen, 0 being the leading edge and 1 being the
trailing edge. This is the location at which the sweep angle is measured.
Dihedral Angle of Planes (Dihed)
