Abstract The
structural
nonlinear
aeroelastic
analysis
of
folding
wings
is
conducted
by
integrating
the
modified
Doublet
Lattice
Method
in
this
paper.
Firstly,
a
modified
Doublet
Lattice
Method
is
investigated
to
relax
the
aspect
ratio
limitation
of
aerodynamic
elements,
and
its
correctness
is
verified
through
numerical
examples.
Secondly,
the
rational
function
approximation
method
is
discussed,
and
the
modified
Doublet
Lattice
Method
is
approximated
using
the
minimum
state
method
to
obtain
the
unsteady
aerodynamic
forces
in
the
time
domain.
Finally,
the
aeroelastic
characteristics
of
a
folding
wing
with
free-play
and
friction
nonlinearity
are
studied
by
integrating
time-domain
