Humble Beginnings - Original Prototype, Circa June, 2002

Over the years we have refined the TSVLS concept to include a single lift rotor located within a shroud and over almost vertical airfoils.  The applications of which are numerous, and include vtol hobby craft, unmanned aerial vehicles, aerial cranes, personal aerial vehicles, 4 to 6 passenger family flyers for sport, local, and regional travel, and commercial and industrial lifting and transportation.

It is now a modular torque stabilized, lifting system with some unique qualities.  It has no moving parts, is absolutely dependable, remains in torque balance under changing power and load conditions, increases lift by 20 to 50%, has no exposed rotor blades, can travel 48 mph horizontally without unbalancing lift, and requires no maintenence.

Where a helicopter tail rotor torque control system uses up to 30% of the total power of the craft, the TSVLS controlls the torque, creating rotational stability, using 0% zero of the crafts power.

We are poised to build the first w Laneorking BodyCopter prototype, depending upon funding.

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
potential applications.
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
dependable.
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.
