Torque Stabilized Vertical Lifting System (TSVLS)
Abstract – by Charles Medlock
Classically trained engineers have been left with the impression it is impossible to
control 100% of the torque generated by a single lift rotor, using only the
downdraft, within the same diameter as the lift rotor, because 100% of the torque
minus 100% of the torque would leave no useable downdraft or zero lift.
This illusion has stymied the development of a torque control system with many
The TSVLS solves the problem by locating a lift rotor over vertical airfoils arrayed
within a shroud to create “horizontal lift” in an anti torque direction. Our testing
shows 100% of the torque can be controlled, balanced, with anti torque forces, even
while the airfoils are at a low angle of attack.
Our testing also shows the torque remains in balance, except for minor trim
adjustments, even when power and load is increased and decreased, because as
power is increased, the downdraft is increased and the anti torque forces are
increased. The torque control is built into the TSVLS module, making it absolutely
Our thought challenge was to visualize how man could take off and land from his
driveway and fly just above treetop with the least amount of hardware. The TSVLS
is our solution to that challenge.
The results of that thought challenge has lead us to believe the TSVLS is the
cheapest, safest, simplest, absolutely dependable way to accomplish personal vertical
flight. The TSVLS could be used in UAVs, as a defensive military platform, to
create a 4 to 6 passenger VTOL family flyer, a 2 seat flyer, as an indoor Radio
Controlled hobby craft, and in commercial and industrial lifting.
We believe the TSVLS will prove to use less power to control torque than any other
method currently employed, whether it be a tail rotor, contra rotating props, or
counter rotating props. The TSVLS increases lift/thrust by up to 40% because the
lift rotor is located within a type “B” shroud. Airfoils have been shown to create up
to 30 times the drag they create. These facts indicate the TSVLS will operate at
over 100% of the lift a rotor can produce without it, while controlling 100% of the
torque generated by a single lift rotor.
Do not read further until you are able to think past the current paradigm that vtol takes, long, free air rotor blades, transmissions, multiple drive shafts, massive horse power, high technology, tip jets, propcopters, tail rotors, contra rotating rotors, counter rotating rotors, computer programming, professional skill, years of work and training, airports, hangers, skilled pilots, a lot of free space, a lot of money etc.
When you can accept the new paradigm of NO MOVING PARTS, you may be able to receive the vision, below.
For those of you who give this some serious thought, you will wonder what horizontal movement will do to the the generation of torque control lateral lift within a vertical duct. Answer: Penn State University gave results of testing a double duct system that allows horizontal travel up to 48 mph with little unbalanced air flow through a vertical duct at the 2010 International Power Lift Conference.
The VW of VTOL, the tsvls system is strictly for low, just above treetop, slow, 50 mph or less, safe, torque control built into the structure of the module, vtol flight.
For those of you who actually consider the idea of average people flying just above treetop at 50mph to work, school, and pleasure, you are bound to think it would use more fuel. But, the fact if you work in Searcy, AR and live in Lonoke, even though it looks like a pretty straight shot, its 37 by road and 20 by air. It would take 25 minutes by air and 45 by car.
GPS guidance will take you straight to your destination, no stops, no tire wear, no collisions, no getting stuck in traffic or the mud and around any obstacles.
You can live on the highest mountain or the lowest valley, reach the most remote places on the planet and land and take off in any 10' clearing.
Inflate floats on the bottom and stop, land on the lake, for a little fishing on the way home.
In the highly unlikely event of an emergency need to land, your electric DC starter motor will automatically engage with emergency power and provide time to pick a landing spot and land safely.
Basically, with yaw (counter rotation) under control, built into the module, all you have is pitch and roll in order to achieve controlled flight. Pitch and roll can be accomplished by rotor tilt and weight-shift in the BodyCopter configuration and with the articulated, steering (top) rotor on the HoverCopter. That, and the yaw trim mechanism, is the entire control system.

Ambient Updraft Power Converter - "Free Electric"
Back in 2005 or there about, my patent attorney made me aware of another possible use for the TSVLS module. He called it the "Ambient Updraft Power Converter" (AUPC) The AUPC is a way to extract electricity from a naturally occurring airflow phenomenon. He reasoned that if an airfoil can create 30 times the drag it causes, in lift, then it can create more electricity than it consumes under the right circumstances.
Larry Lee, the attorney, now deceased, said to visualize ambient air molecules as little ball bearings, all with a certain amount of weight depending upon their altitude. Air molecules get lighter in higher altitude and heavier in lower altitude.
In a vertical duct, lighter molecules above the top of a vertical duct draw the heavier molecules upward to equalize ambient pressure, or, another way of saying it is that the air molecules surrounding the duct all have weight, the same amount as inside the duct, but because the duct's height is higher than molecules horizontal to molecules inside the duct, the outside molecules weight is transferred to molecules inside the duct, according to their angle, above, and distance from the bottom of the duct. This weight pressing on the molecules at the bottom of the duct forces them upward inside the duct, producing an ambient updraft.
So that, if we constructed a vertical duct of sufficient length to generate enough of an updraft, the weight of the air surrounding the duct would force air upward into, and out of the top, of the duct. This power source could then be used to generate "horizontal lift" and rotate a TSVLS module located inside of the duct, and turn a generator and produce electricity.
I was able to find very little information concerning the airflow from such a set up. Ambient updraft doesn't seem to be a well known phenomenon. But, I did construct a 40' or so high 3' diameter duct and got a 4 or 5 mph upward airflow reading on a meter. Being that I was working by myself and moved from the home where the construction was, that was as far as I got. My impression was that with a taller duct, it may have been possible to capture energy for electric production.
I also added a cap to the top of the duct that turned any horizontal airflow into a suction at the top of the duct to see if that would help the airflow. It also occurred to me to wrap the duct in black solar tape to increase the heat in the duct to further increase the updraft, although I never did that.
Larry, a former engineer, and my personal technical department, assured me chimneys will draw air in from the bottom, if over a certain height, even when there is no fire.
My vision was to build houses with a centrally located duct, maybe 5' in diameter, located in the center of the house and possible 100' tall, wrapped in solar film and topped with a cap made for turning any horizontal wind into a vacuum to draw air upward. The duct would have to have guide wires to secure it in bad weather and high winds. Since, cool air, the kind under a house, because of the earth's constant temperature in the 50s, is heavier than warm air, it will naturally move upward faster when it is warmed by the sun and ambient air surrounding the duct extending above the roof. Or, depending upon the ambient updraft formula, and whether the house would interfere with airflow, the duct may need to be located somewhere else on the grounds.
I hope, one day to have the funding to test the "Ambient Updraft Power Converter". Larry has two sons I'd like to be partners with one day, creating "FREE ELECRIC" for the world from the AUPC.
Yes, I would charge for the AUPC, I'm not totally deranged.
