Instructions for a control system.

(The Russian has been machine translated by Google translator; improved translation is invited by anyone; thanks. )

  • 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 declined.
    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.
    Sincerely, Vladimir
    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 motor.
    Just in case.

  • Hi LIFT,
    Others will send pictures later - I do not always have a computer close at hand.

More input given on March 21, 2010:

Hello, Lift.
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.
Airborne wind energy conversion systems via tethered means includes most hang gliders.
And new new hang gliding activities and launching modes are being developed

Milestone Flight on a Wills Wing Falcon!

Patent number: 3140842
Filing date: Mar 17, 1961


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 unusually slow.

DRAFT, inviting comment. Thanks for your moment guys.
“We might extend the application of [wind] power to the heights of the clouds,
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 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.

Now, that  private DRAFT paragraph is up for anyone in the public to draft polish; thanks for any polishing you may have. Thanks.
