Variable-Drag Delta Kite
Perhaps the best way to vary drag in an AWECS is a separate a
pilot-lift kite with a vari-drogue hung below. Nevertheless, an integrated
approach has advantages, just as a conventional aircraft has built-in
flaps to add drag for landing (or high lift w/ high drag).
The attached KiteLab JPG shows a proper built-in flap configuration on a
conventional delta kite. Note that the flap is just aft of the
bridle-point axis, providing a balanced drag input, with the kites natural
stability features still active. The flap has a slit for the delta's
ventral dart, which also acts as an "apex-hole" stabilizer.
By running two lines to the kite from a common pulley the control input is
made with little force while the drag force varies greatly. The next step
is for this cycle to be passively actuated thru a power-lever work-cell
for a self-piloted AWECS.
