Basic Elements of 3D Kite Lattices
The basic elements required to assemble an
endless variety of kite-based flying energy latticeworks are as follows:
Lattice Lines: Specified in standard lengths and
test-strength, and applied according to geometry and load conditions. A
standard line has a loop at each end for attaching to a shackle or
larks-heading onto a junction stopper knot.
Junctions: Multi-line interconnects. The simplest
junction is a knotted "spider" with as many free end-knots (stopper knots)
as required to attach lattice-lines. Carabiners, shackles, and rigging
plates are standard methods.
Kites: Free-kites on short leaders able to sweep
and orient in any direction (+3DOF). Lattice-Kites- Semi-captive kites
able to orient somewhat along a line (~2-3 DOF). Captive Kite surfaces
constrained by the lattice (0-2 DOF). Pilot-Lifter Kites- Used to initiate
early lattice launch, to maintain presence at altitude during lulls, etc..
Drogues: Used as stabilizers, tensioners, or WECS
WECS: Energy converters (transducers) of varied
kinds. Rotors, Wingmills, etc.
Workcells: Ground-based power application points
(cranking, reeling, or pumping work; i.e., Groundgens)
GroundGens and FEGS: WECS interfaces for
Reels/Capstans/Winches/Winders: Storage and/or
retraction; A WECS interface option.
Anchors: Specified depending on geology and
operational conditions (soil-kites, mass-bags, stakes, etc.) (mobile
(vehicles), turrets, or static)
Blocks: Pulleys for halyards and corner-blocks as
force-directors, tensioners, equalizers, etc.
Swivels: Simple swivels for avoiding twist of
single lines (ie- leaders), and tri-swivels for looping kites along a main
Shackles: Used for connecting and especially
quick disconnecting under load.
Halyards: Line loops thru Halyard-Blocks for
raising or lowering WECS and other elements.
Control Lines: Used to adjust to conditions
(tuning); Reef Lines, Kill Lines, Steering Lines, etc.
KiteShed: A storage and maintenance space.
