My main work was done to optimize the method of
controlling hang gliders.
I managed to find the optimum point for the application of forces,
as well as the optimal way of application of forces. To confirm this,
I have produced a prototype of a complex control system and installed it
on an ordinary double hang glider with a motor. After that we went to the main
pilot in the air, and tested. Test results exceeded my expectations. Pressures feeding commands to
the flight control
decreased significantly (approximately 10 times). This means that the
executive control lever
can be significantly reduced, and the space in which it operates, also
And it is now possible to replace the trapezium-(airframe and speedbar)
for a more compact body control (steering wheel, or a stack),
make the aerodynamic cab abandon cable supports, to reduce the length of the
suspension (from the center of gravity of the suspension, to knot the
suspension system), while not to lose not one good dignity sailing wing.
In this invention, I received a patent.
Now I'll have a picture cover sheet, in my patent for an invention
which I described earlier.
Work on the patent lasted, and now this theme is improved (simplified) state.
Now it's wing, in a state more suited for use not only for normal use, but as
a flapping near the bat, (the family of bats).
Regarding confirmation. Flight tests, which I wrote in previous reports, they
are not difficult to repeat, in the presence of double hang glider with a

Excuse me for not writing for a long time. If you are still interested in my
work, I’m sending you a picture with a small part of my work.
This hangglider I have invented in 1990 and the same time I’ve started to make
it. In 2000 it was made for more than 90%. To comparу I’ve drawn a usual
hangglider (on the left). Decided to patent it in 95. Applicated for it.
This is an amphibia. It’s model has an optimized aerodinamic because of pneumo
cylinders which can can be in two conditions: (2) – filled with gas and (4)
vacuum; and because of the underwater wings the vehicle easely cope with
sticking on the water and getting off the water.
When the pilot is going to land on the water he must fill the side cylinders
(2,4) with gas for better floatability, and put down the supporting floats
(5). The landing has a consecutive order: - glidepath, the vehicle smoothly
lowers the speed, touch the water with underwater wings and the further
landing continues with the underwater wings till the full stop.
Taking off from the water goes in the reverse order. The vehicle starts to
move with the underwater wings. It makes easier to take off from the water.
Then the supporting side cylinders (5) must be put off and vacuumed including
floats (2); (4). It must be done during the flight.
I planned to make and use an extra pneumocylinder on the wing section for
increasing the temporary thickness of the section and vacuuming it for
increasing the range of the speed and capacity.
For coping with these problems I’v invented few things in such areas as
science of materials, ways, instruments and devices. They help quickly and
easely cope with such technicl problems.
On this picture (in the lower left corner) you can see the illustration for
the “flapping wings” theme.
Francis (Frank) Herbert Wenham, i.e.,
F. H. Wenham delivered a formal paper and its reading in 1866. He wrote
the paper in either 1859 or 1860 (by calculation from a note within the
delivered paper). "On
Aerial Locomotion and the Laws by which Heavy Bodies impelled through Air
are Sustained," at the first meeting of the Aeronautical Society
of Great Britain, held on the 27th day of June, 1866. His Grace the Duke
of Argyll in the Chair. In the paper he described built and tried
hang gliders--several versions. In a version it is clear that he had
placed a pilot in a triangle frame part at the bottom of the wing set and
from running had the pilot then be in prone position. "Fig. 3 represents the
arrangement. a a is a thin plank, tapered at the outer ends, and attached
at the base to a triangle, b, made of similar plank, for the insertion of
the body. The boards, a a, were trussed with thin bands of iron, c
c, ..." It is clear he had the equivalent of a
cable-stayed triangle at the low part of a hang glider. So, it is
not surprising that much later--in the year of Wenham's death: 1908: a
gliding club would again explore similarly--and in the territory of
Breslau--have a tethered (hang lined) hung hang glider pilot behind a
cable-stayed triangle control frame.
Also, only lacking modern materials,
it is clear by words, drawings, and description of actual build-try field
experiments, that he had envisioned high-performance monoplane hang
gliders; in deference of having the benefit of modern materials for
lighter spars, he patented the multi-plane shorter span hang glider for
aeroplane aims. JpF
Hang gliding has a positive intersection with AWE.

ML 1. (Utility Aircraft, Inflatable wing).
In 1955 ML Aviation designed and produced a portable flying machine that
was given the serial number XK776. The aircraft featured an inflatable
rubberized fabric wing and quick release fittings enabling the aircraft to
be rigged and de-rigged fairly quickly. The flight characteristics were

“We might extend the application of [wind] power to the heights of the
by means of kites.” ~utopian technologist John Etzler, 1833
Short-tethered free-flying kites with pilot as mooring would evolve and be
called hang gliders. At times the tether was the tendons of the pilot.
Then came short tethers, as exampled in Breslau in 1908 (of the
Schlesischer Flugsport Club) when the cable-stayed triangle control frame
was set in front of the tether-hung hang glider kite pilot to push and
pull while he or she moored the wing above; we still frequently use that
cable-stayed triangle control bar as in 1908 or earlier; many who re-find
this triangle, hung pilot, short-tether-to-wing arrangement feel as though
they have globally invented; indeed what they find is a true breakthrough
for their personal life and those they then influence with their
excitement. Longer tethers and substitution of control lines for the
triangle control frame permitted another version of hang glider kiting of
humans: paragliding where the pilot is again the mooring point for the
kite system. Way before Spratt, Bensen, tow kiters, or Palmer, the hung
pilot behind a triangle control frame (TCF) was fitted to a hang glider
...at least 54 years earlier than Palmer, 55 years before Burns and
Hobson, and as much and more before the later users in Australia and North
America. Variations along the way gave color and richness to the
free-flying hang glider kite system. The control frame used by the hung
pilot varied in size, angle form, staying manner, degree of fairing,
proportion in size to the pilot, material, and use.
