Ahead- and back-turning spiral track

Sling-effect
Basis of conciderations here is that Sling-effect, as described above, by this picture. After a turn (here clockwise) of some 180 degrees, effective mass will show an angles-speed one third higher than angle-speed of rotor-arm (green dotted lines). Above that, kinetic energy is given at a larger lever arm (here 1.5 times as long as the rotor-arm).

Essential reason of this additional energy is, an Addition of pulling- and inertia-forces by these motions will happen. This surplus of energy, by Felix Würth was demonstrated by many experiments.

Already the concept of Swivel-arm-maschine did show a limited sling-out-phases of maximum some 90 degrees. This limit will make sence, cause at the early phase of sling-out, relation of pulling-force and given speed of effective mass, even a better one will be.

The motion towards outside (e.g. at A), corresponds well to given direction of inertia. Pulling-force there, nearby will be parallel to the direction of the rotor-arm. Thus, the rotor-arm must bring a but small power-component towars radial dircection. However, when the rotor does show a right angle towards the rotor-arm (nearby B), the rotor-arm must pull full power towards radial direction. So it makes sence, here to stop that slinging outward of mass.

Swivel-arm-maschine
At the Swivel-arm-maschine, a rotor-arm (RT) does move around the system axis (SA). At the outer end of the rotor-arm, a lever-arm (SH) is mounted turnable. At its outer end, effective mass (MP) shall be installed, here shaped like a roller, rolling alongside an excentric wall (EW).

While the rotor-arm does turn (here counter-clockwise), from an inner position (here upside), the mass can fall outside (here to below) and thereby will achieve high kinetic energy. Afterward, the mass will be guided back towards its inner track point by the excentric wall. Same time, the mass will be decelerated, to some half of its speed outside.

Forces thereby will effect turning of the rotor-arm, but also will effect pressure against the wall. Cause whole wall (practically a hollow round cylinder) can turn around the system axis, this power-component will result a turning motion of the system as a whole (for example by a gear of 1 to 10). Moving inward of mass and its deceleration thereby does not effect any loss of energy.

Threefold crank concept
Above, that principle of motions at apple-shaped tracks resp. out- and inwards turning spiral tracks, was based at a theoretical motion-system of three cranks resp. pendulum. Analog to this, also this motion here should be reduced in principle to three cranks or pendulum.

Thereto, instead of the excentric wall, here excenter-arms (ET) are drawn, which cover the distance between excenter axis and the middle of the lever-arm (SH). These excenter-arms, naturally must be turnable at both ends by bearings. Like at other concepts, here the excenter-arm will turn by different speeds, so each mass must have an excenter-arm for its own.

In orde to get that turning ahead and back of masses, the excenter-arm must be shorter than the rotor-arm. Thus, the excenter-arm all times will stay behind the rotor-arm (in direction of general turning). Thus, also the mass all times will stay behind the rotor-arm. Thus, that critical phase of overtake (mass versus rotor-arm) does not exist here.

Excentrical track
At EVVR 03 positions are shown after each 30 degrees turning of the rotor-arm. The most inner position of the mass will be, when the excenter-arm does show in direction of system-axis (here towards upside, mass point upside right). Correspondingly, the mass will be at its outmost track point, when the excenter-arm shows off the system axis (here towards downside, mass point downside left).

It´s obvious, that sling-motion (upside left) does show enormous acceleration. At the other hand, the track shows inside (downside right), where that pulling inwards of mass, by the excenter-arm will de done.

At EVVR 04 power-effects of both situations are shown. Left side, situation of sling-outside is marked, right side situation of pulling-inside is shown, each by two positions of each constructionals element.

Mass did move from A to B and its inertia does show towards upside left out (green dotted lines). That mass must be moved to C, while the rotor-arm (blue lines) will move from D to E. The motion towards inside, by the excenter-arm (grey lines) will be done. But a small distance, the mass must be moved by the rotor-arm (black arrow).

Here one can see, that motion neccessary, nearby parallel to direction of rotor-arm will be. Thus, but a small power-component towards radial direction must be done (most of the work will be done by pressure within the rotor-arm, analog to that pulling forces covered by spokes of normal wheels.

Excenter-axis turning
Important now will be: at the one hand, the mass will swing around the excenter-arm, thus pulling at the excenter-axis (here to left side). At the other hand, the rotor-arm does pull the mass, thus indirect also the excenter-arm. Turning of rotor-arm, so will make pressure towards the excenter-axis (here to right side). Thus, while slinging-out the mass, not at all whole inertia power will press towards the excenter-unit.

At the section about Swivel-arm-maschine, graphically was shown, the mass by falling-outside, at a inner curved track practically will fly over the excentric wall (cause the rotor-arm pulls the mass off the excentric wall). This reduced pressure (at the excenter-axis) counter the turning direction of the system, by this crank-concept here is confirmed.

At the situation opposite, the mass is moved from F to G. Here now, inertia power will take far over next position (grey arrow), thus the mass will be decelerated. Also here, the inward motion by the excenter-arm will be done, thus inertia power directed towards rotor-arm. So, the reduction of kinetic energy by that deceleration, an acceleration-momentum towards the rotor-arm will result.

By this deviation, also an essential power-component will exist, pulling at the excenter-arm, thus pulling the excenter-axis. That pull-power of intaking-mass-phase (here towards right side), is much higher than the opposite power of falling-out-phase above. Thus, not at all a balance of forces will exist. By this system, the excenter-axis thus will move also in direction of general turning of the system - if excenter-axis won´t be fixed at a point within the housing.

Excentric-wall turning
At Swivel-arm-maschine, an excentric wall was installed, turnable around the excenter axis. The mass has to roll alongside this wall. Pressure towards that wall is different in different phases. Thus it´s difficult to achieve round and noisless running maschines. Here at the excenter-arm-concept, the mass all times is guided well, thus easily a good running maschine could be constructed.

Figure EVVR 05 once more does show the constellation above, in larger scale. Here however the mass is concentrated direct at the end of the excenter arm. So the effective mass will move at a circle track around the excenter axis. So far, the problem of falling-out and taking-in of mass is not relevant, all centrifugal forces do pull at the excenter-axis, in sum will compensate each other.

Mass points (green points) however will move with very different speed, so highly different inertia forces will exist. Below, once more two situations are marked, left side the acceleration-phase, right side corresponding deceleration. As mentioned above, in order to accelerate the mass, the rotor-arm must pull but with small power. Partly this pull-power will make pressure towards the excenter-axis, so the excenter-axis must not take whole amount of centrifugal forces, counter the general turning sence. So this power-component will result (relative) co-turning of the excenter-axis, thus won´t be lost (in general turning sence of the system).

Opposite, inertia power either will push the rotor-arm (nearby in tangential direction), or will pull at the excenter-axis, both in general turning sence. This co-turning however, not at all is effected by the input-momentum of the rotor-arm. This additional turning does result of inertia, through sling effect.

Energy-balance
Already this static picture does show, minimum speed of mass (upside right) will be some third less than average speed, maximum speed of mass (downside left) will be one half higher than average angles speed (in relation to excenter-axis). Corresponding to these different speeds, kinetic energy of mass will be in divers situations.

When now the excenter-axis will also turn, the circle track of mass will change to outwards- and inwards-bended spiral tracks. At falling-out, the track will become ´straighter and straighter´, so inertia power more and more will show into direction of motion. While the rotor-arm is turning same speed all times, the mass at the end of acceleration does show remarkable higher angle-speed, and same time this higher kinetic energy is available at nearby double-length lever-arm (in relation to system axis, thus comparable absolutly, by absolut speed over basis). If one wants to achieve same kinetic energy by accelerating mass at a fix lever arm of constant length, important more energy it would take.

Opposite, at the deceleration-phase, the track does show a curve, becoming narrow more and more. Whole additional energy of sling-out-acceleration, by rotor-arm and excenter-arm will be feed into general turning of system. That kind, this theoretical model of three cranks, does show a true picture of power-effects of Swivel-arm-maschine above. These motions in principle, by diverse designs technically can be realized. Might be, including one bearing within the other will make sence, analog to the procedure at diverse sections of chapter Crop-circle above. (Remark: the remarkable design of Centrifugal power-spider at this time wasn´t created. But these conciderations about power-effects here, also are valid to that simple and consequent design).

Results
The motion of mass at outward- and inward-turning spiral tracks, practically turning ahead-ouside and backwars-inside again (in relation to general turning sence of system), thus seems to have some advantages (versus the motions at loop-tracks, especially versus that critical phase of overtaking mass/rotor-arm).

Already in 1998, at my scripts to Würth-Rotor-Systems, I claimed a perpetuum mobile must show: excentric masses moved at asymmetric tracks with un-steady speed, where center of turning may not be center of support. Some aspects of the effects described here, Felix did demonstrate by lots of experiments. However, quite new here the essential aspect is, mass must be pushed towards inside by a separate element (or pulled inside - but nor by a normal spoke at normal wheels).

Here I did try, to give theoretical reasons for these effects and same time to design concepts, which technically can easy be realized. With this basic concept here, in my oppinion, all demands for a perpetuum mobile are fulfilled. Ok, all well educated physican by sure do know, this might never be possible. Education-institutes will guarantee, also next generations of students are convinced of. Don´t let them calculate that simple mechanic of EVVR 05, stable-seeming education might crack.

So I am a happy layman, nobody can stop me thinking prohibitted stuff. So I am sure, this maschine will run. However, I am still not content with: corp circle picture seems to solve that problem much smarter manner.
