Digital Object Identifier 10.1109/CDC.2006.377210 Summary:In this paper we present a challenging
application of periodic optimal control. A kite that is towing a ship
into a given target direction should fly optimal loops. We show how to
find the maximum average tractive force by controlling the roll angle of
the towing kite taking into account that the wind is increasing with the
altitude over the sea. The optimal control problem for this highly
nonlinear and unstable system has periodicity constraints, free initial
values, and a free cycle duration. For its solution, we use MUSCOD-II,
an optimal control package based on the direct multiple shooting method.
Finally, we discuss the influence of an important design parameter, the
effective glide ratio of the kite

PRELIMINARY INVESTIGATION OF A PARAGLIDER: LANGLEY RESEARCH CENTER
TECHNICAL NOTE D-443. Francis M. Rogallo, J. G. Lowry, D. R Croom and R
T. Taylor. National Aeronautics and Space Administration, 1960.[Editor:
Notice that in 1960 "paraglider" included stiffened Rogallo wing
devices. In 1961, the stiffenened Rogallo wing made by the team under
Charles Richards at NASA produced the full wing portability and
collapsibility of aluminum tube frame, battened sails, Dacron sail and
format that provided (along with the similar Fleep wings) the template
for the first round of standard Rogallo-wing hang gliders; in 1961-2,
such devices were still called "paragliders" and "kite-like glider".
Later, as Barish sailwing and governable Jalber parafoils and hang
gliding had a renaissance of hang gliding activity, the fully limp hang
glider began to be named "paraglider" and the stiffenened hang gliders,
just "hang glider" even while all were hang gliders that had the pilot
hung from the kite-line in freeflight to tug the wing; the pilot would
push and pull the airframe of the kite's wing to control the freeflight
of the gliding kite system that was an activity called hang gliding (and
if the hang gliding was with a fully limp governable wing, then called
parakiting (if ground moored either fixed or mobile) and "paragliding"
when freeflight occurred. Either the kite system was fixed to an immobile
or mobile ground mooring or the kite system was moored to a hung
free-falling pilot.] [Such kites or paragliders can be involved in
electricity-generation systems regardless of the level of stiffness or
limpness of the kite; there will be niche applications for all levels of
stiffness. Notice that the coming nanotech materials will be allowing
full "solid" extremely low-density wings for working systems; there is
talk of a lighter-than-air "solid" enabling forming kytoons where
concern for gas replacement does not measure into the challenge.]
