Abstract:
Effects of various wing-body interaction design
parameter variations on the structural behaviour of
a small RPV have been investigated using the finite
element method on an adhoc basis rather than a classical
analytic approach.
The method in use is based on the substructuring
displacement method considering the body and the wing as
two major substructures. The elastic coupling effect
of wing stiffness on the body structural behaviour also
examined. By comparing classical analysis methods to the
present. investigation, comments are made upon the use of
those methods in the design analysis of the RPV class
of structure. From the calculated results, general
guidelines on the structural wing-body interaction
analysis or design of this class of vehicle have been
proposed.
A set of finite element programs have been developed
for the present investigation, and relevant finite elements
based on the displacement assumption have been formulated.
