Abstract
The single-shooting method is used to identify optimal manoeuvres in the lateral dyna-
mics of partially-supported flexible wings. Efficient actuation strategies are sought when
large wing deflections substantially modify the geometry of the vehicle during the man-
oeuvre. For that purpose, geometrical nonlinear models are first built using composite
beams and an unsteady vortex lattice, and the optimal control problem is then solved via a
gradient-based algorithm. A flight-dynamics model based on elastified stability derivatives
is shown to capture the relevant dynamics either under slow actuation or for stiff wings and
it is used as a reference. Embedding the full aeroelastic description into the optimisation
framework expands the space of achievable manoeuvres, such as quick wing response with
low structural vibrations or large lateral forces with minimal lift losses.
