Disambiguation Note- CoopIP is being renamed FairIP, where any AWE conceptual
creator working outside the broken patent system can claim a moral right to
compensation on an "honor system" basis. It is anticipated that socially
responsible companies will honor & even create FairIP, if costs are kept low
overall & lower than competitive patented IP.
CoopIP is henceforth defined as pooled FairIP & patents, copyrights, etc. along
cooperative principles. ~~~~ DS, April 16, 2010

Single-loop through two ground pulleys. Gear at lofted spinning kite-lofted
wing drives the loop; the driven loop rotates ground-station generator or pump.
The main tether could be a double-line (two parts of tensed loop).
A main tether plus a loop brings three lines occurring
"run a continuous loop of line from a capstan on the turbine to one on the
ground gen" DaveS concerning alternative to torsion tube driving
ground-based generator as he was weighing how torsion tube method limits system
to low altitude winds.
Contrast stay-aloft-spinning driver systems
from the method where kites go up and go down in a loop; both have a driven
loop, but the wings-stay-aloft method is quite distinct from the wings rotate
up and down via changes of angle of attach of the wings.

flap wiki
[[Aileronsare
similar to flaps (and work the same way) but are intended to provide lateral
control, rather than to change the lifting characteristics of both wings
together, and so operate differentially - when an aileron on one wing increases
the lift, the opposite aileron does not, and will often work to decrease lift.
Some aircraft useflaperons,
which combine both the functionality of flaps and ailerons in a single control,
working together to increase lift, but to slightly different degrees so the
aircraft will roll toward the side generating the least lift. Flaperons were
used by theFairey
Aviation Companyas
early as 1916 but didn't become common until afterWorld
War II.]]

wikiStudy. Note1: "A standard two-way freewheel solution to drive a
generator is a BMX flip-flop hub. The bike wheel could be packed with
concrete to make it a flywheel & the rim could fit a belt that drives a small
pulley on the gen. A flip-flopped chainwheel would be another step-up stage &
complete the drive train. A lever or spool on the bottom bracket would be
driven by the two-way kite." May 27, 2009, Dave
Santos
Note2: This is great news! A bicycle wheel can be filled with concrete
between the spokes. A circular, donut plywood "floor", for the bottom side of
the wheel, is made. Then filled with concrete.
So the Flip-Flop hub, chain-coupled with a Flip-Flop crank gear as well, to
take the back-and-forth motion, and turn it into constant 'round-and-'round
motion. A constant-velocity transmission to keep the crank rotating at the same
velocity, even in low-speed winds. ~Darin Selby
An integral airfoil that has rapid change of angle of
attack so as to cause a rotation about a axis is flipping and thus a flip wing;
the rotation may be full and continuing or may be partial and reversing. Do not
confuse
Savonius or Darrieus arrangements as flipwing as they are composites of two
or more airfoils with special interactions because of the multiplicity.
flip-wing now: flipwing
"public domain technical class name" +Dave Santos
Some
flipwings shunt, some do not shunt. "Fundamentally the FlipWing is two-line
"reversible" C-kite stretched out to the superior higher-lift flat geometry of
a multi-bridled bow-kite, but, being single skin, is lower mass & way cheaper."
Dave Santos
x-FLPHG (the x is a variable suggesting option prime mover)
The motor or engine is an assist to obtain soaring or gliding altitude.
One vision has an x-FLPHG launch from flatland; then upon reaching
altitude, the system drops a tether to be connected with a second glider to
form a two-kite system that mines wind strata differentials for
FF-AWE for
travel and some additional energy mining from upper winds' kinetic energy
either horizontal, gust, or thermic.

Mostly in aviation "flutter" is a bad thing; the same is true in much of
AWECS, but not all; there are some strong special interests in mining flutter
for energy from winds. Flutter mining.

KiteTrains
where well-spaced wings on a tether result in a global "rope" that is well
lifting along the length; stand back visually and let the image of wings blur
into a macro image of "rope." A separate lifter kite is not needed beyond
what appears from a distance as fat rope flying. Just how tiny might the
segment wings be in a kite train to effect a "flying rope" status for the macro
structure?
Dave Culp proposed a continuous linear soft kite for "flying
rope". Details for the structure envisioned are not forward yet. Santos
extended the term to "self-lifted line"

Rotating-tape or rotating ribbon kites are flying rope of particular shape
and held by two anchor stations. Such are one sort of kite arch.
KiteArch
Some kite arches are complex-shaped "ropes" that fly. Consider Mothra.
KiteArch
A continuous line or rope hung from of a kited wing will
have positive lift and positive drag as the wind impacts the windward surface
of the rope. Many streaming tails of kite systems are essentially lifting
flying ropes of particular shape.

Note: A kite (wing, tether, resistive set) has a tether set that does not
really have any "free end" as the resistive set occupies the lower end of the
tethers; that occupation makes the "end" not free.

efforts to distinguish the use of the term in distinct circumstances: wiki That is, "free fall " does not mean the same thing in some
distinct scenes. Confusions may result when parties are analyzing matters
without the same definitions for terms used in conversation.
Free-flight AWE, Free-flight AWECS, FF-AWE,
FFAWE, Methods and applications vary for FF-AWE.
RATs as auxiliaries on powered and unpowered untethered or tethered aircraft
are a subset of FF-AWE with tethered and untethered versions. Also, there
is the category of FF-AWE that is fully unpowered with a tether system
terminated with lifting bodies set and controlled in different wind
environments. FF-AWE may be purposed for soaring transportation or for
energy production or combinations thereof.
Here is an expression by DaveS for one of the categories of FF-AWE: Free-Flight is the term used for sustained flight
by multiple tethered-foils opposed across a wind gradient. The Planetary
Boundary Layer is the most common gradient. Small scale kites have already
sustained flight downwind, but tethered-foils can in principle fly in any
direction faster than the wind.
Soaring champion Dale C. Kramer
proposes to pilot the first manned free-flight test, which would consist of his
high-performance sailplane tethered over several thousand feet to a large
soft-kite. While Dale can get clearance for a demonstration, popularization of
this flight mode in the NAS will require NextGen flight trajectory and
moving-constrained-airspace control. ~~DaveS, December
2010.
"FreeFlight" is a term used to
describe "Tethered Airfoils" (two (or more) wings tethered together)
sustaining flight by working across wind-shear. A hapa is closely
similar in operation, but with one "wing" in a water medium.
FreeFlight-Hapa hybrid classes are suggested:
-An aero-wing mounted with a J-foil, or equivalent, can
operate either as a hapa
or a free-flight component and transition
smoothly between modes.
-Two wings with a hydrofoil on the tether between them
can operate as a double kite hapa,
or operate in freeflight with the paravane
carried along.
Some interesting hybrid modes:
-A "payload wing" operating by surface effect, and the
other kite wing far up in good wind.
-Pairs of
Sailrocket-like platforms flying in alternation, or taking off together
for extended flights.
-The paravane as a "flying submarine" basis. Wings and
all could submerge,
to operate powered by currents.
Call it a Protean Rig (Yacht). Its fussy handling
suggests it be called a "Prig".

Various meanings.
One is flying without having to respect defined flight tasks.
Clip from that PDF: "Frederick To, AMRAeS was born in Hong Kong in
1938, came to the UK in 1952 to study, and qualified as an architect. He joined
the RAeS in the early 70s, his main interest then was man-powered flight. In
1974 he made a documentary film on the subject called "The Last Challenge". He
started building Solar One with the help and advice of David Williams in 1977.
The next year Solar One made its first short hop at Lasham and it is believed
it then became the world's first solar powered aircraft. By the middle of 1978
Fred To was making structural tests on the use of polyester film structures for
an inflatable wing. He designed and built 'Phoenix,' the success of which is
illustrated in this paper. He also tried unsuccessfully to produce an
inflatable microlight, a project which was hampered in mid-life by the
introduction of CAA regulations. In 1980 he formed his own company, The
Air-Plane Co to
undertake inflatable aircraft powered by a 22 hp engine. He still practises as
an architect."
