Description

CENTRIFUGAL FORCE - DRIVE

The invention relates to a centrifugal drive by means of guided flywheels.

The object of the invention is to create

a centrifugal drive using guided flywheels, which generates a constantly acting, directed thrust force,

which also so,

how centrifugal force builds up without support from its center of rotation, also works without support on a medium such as earth, water, air or fire.

The solution of this problem according to the invention is achieved by the teaching according to the characterizing part of claim 1.

A guideway pattern can be produced as follows:

a paper strip of approximately 300 mm length and 15 mm width is held at one end and twisted 360 ° at the other end, after which the two ends are joined together, e.g. by gluing.

Advantageous embodiments of the invention are specified in the subclaims.

The released thrust force increases with the angular velocity ω or the speed v squared, so that with a relatively small centrifugal drive considerable thrust forces can be generated that act without the aforementioned support media.

However, the quadratic increase in thrust does not require an equal increase in drive energy, because the centrifugal force that generates thrust only acts indirectly, so that a primary drive only has to accelerate the flywheel masses to the desired angular velocity and, with constant rotation,

only has to cover the friction losses. ^

The acceleration power therefore does not need to be significantly greater than that required to cover the friction losses if the primary drive is given enough time to ramp up the flywheel masses.

This means that the centrifugal drive is not designed according to the force-performance principle, but requires less than 2% of the drive power compared to conventional drives to generate the same thrust.

Thus, not every near-earth vehicle has to carry its own energy generator, which is, however, expedient in ships or space vehicles, preferably as an arrangement according to claim 11 and/or as a solar generator.

As an energy source, a conventional battery pack, which only allows an electric car to drive about 125 km on one charge, is more than sufficient, because due to the 98% energy saving according to the invention, about 6,000 km can be driven on one charge.

As a closed system, the centrifugal drive according to the invention only reacts to external accelerations and decelerations, and at constant speed it behaves as if they were not present.

In this way, a further acceleration boost can be added to any speed already reached in order to achieve very high vehicle speeds.

For road vehicles,

a centrifugal drive according to the invention for accelerating and braking, if it is arranged so that it can pivot in the direction of travel.

At a constant flywheel speed, the thrust force is directed downwards and

directed forwards or backwards when driving or braking.

For hover vehicles near the ground, two centrifugal drives according to the invention are arranged so that they can pivot on all sides, for the purposes of safety, lateral thrust compensation and good maneuverability, and their flywheel masses can rotate at a constant speed.

In this structure, gravity acts as a stabilizing counterpole, and the thrust of the individual centrifugal drives can be directed in such a way that they cancel each other out, add to each other, or act as a resulting thrust force.

As a result, such vehicles

take off very quickly, fly and decelerate, hover, lift loads or the like.

For space vehicles,

which have to stabilize themselves without a counterpole, three or more centrifugal drives according to the invention are required to enable all control maneuvers to be carried out quickly and precisely. Otherwise, the structure is similar to that for hovering vehicles near the earth.

For surface and underwater vehicles, a pivoting centrifugal drive according to the invention in the bow and stern is sufficient to achieve unprecedented maneuverability without a propeller or rudder.

No known state of the art comes
in structure and operation of the invention.

In previous attempts with the same goal

the effects of rotating masses cancel each other out or produce unusable forces or jumping movements.

DE -A- 2 536 469 (GROSSMANN)

describes a "centrifugal gear" ,

in which flywheel masses A are arranged on a radius R (Fig. 1) around an axis b, each rotating on its own axis a, while the axes a and b are at an angle of approximately 90° to each other.

The masses move around the axis a with the velocity ν 2 and simultaneously with the velocity ν j around the axis b .

Thus, the velocities &ngr; \ and &ngr; 2 add up only at the moment of passage A (Fig. 2) and subtract at the same moment (&ngr; \ - &ngr; 2) on the opposite side at the passage point A " ,

which should create a differential thrust in direction P.

However, what was overlooked here was

that the masses A also generate their own radially directed centrifugal force, which, as can be clearly seen from the flywheel mass positions A ¹ , A" ¹ (Fig. 2), together with the thrust force P" counteract the thrust force P and thus completely neutralize each other.

No matter how the masses and axes are adjusted to each other, the forces in this system always neutralize each other, so that only undesirable torque and imbalance effects remain.

US -A- 4 884 465 (ZACHYTAL) and

DE -B- 1 476 678 (DI BELLA) ^

want to generate a resulting thrust force through a rotating flywheel mass, by simultaneously rotating it around a second axis that is perpendicular to the flywheel mass axis.

No matter how the flywheel is guided, it points in a different direction at every moment of its orbit, cannot form a resultant with itself and can only produce jumping movements.

DE -A- 2 046 865 (POHLIG - HECKEL - BLEICHERT ... AG) :

a "balancing gear" with the same structure and operation as described above in US -A- 4 884 465 and DE -B- 1 467 678

is intended to generate upward thrust forces.

The arrangement of four flywheel masses cancels out the transverse forces, but this does not prevent Coriolis forces from occurring due to the transverse rotations.

These Coriolis forces counteract and neutralize the pulsating centrifugal vertical forces.

Since the function only exists at equal angular velocities around the x and y axes, the ratio of centrifugal force to Coriolis force cannot be changed by anything.

FR -A- 2 216 461 (MIZRAHI)

found that the masses rotating within a circular path generate a directed centrifugal force when the motor driving the masses is displaced from its central position.

However, as particularly highlighted, since the masses are flexibly connected to the drive, the drive axle displacement does not even create an imbalance, let alone a directed centrifugal force. The masses continue to follow their predetermined path as if they were circling a fixed shaft.

The arrangement (shown there in Fig. 1) to achieve the same goal by means of track depressions cannot be taken seriously.

The invention is explained in more detail using the drawing . They show:

eight centrifugal drives mounted on two counter-rotating axles, to drive four generators via a planetary gear.

Fig. 1 and 2 :

On a twisted guide track 1 similar to a figure 8, as many flywheel masses 2 as possible are arranged,

which are each carried by roller carriages 3 with six rollers 4 each and are held at the same mutual (minimum) distance at the neutral point by tension or compression elements, e.g. a rope 5.

As an alternative to the roller carriages 3 with six rollers 4 each, the roller portion can be halved using a different track profile or a direct ball guide can be installed.

For very high speeds, a magnetic levitation train using superconductors is also conceivable.

The guide track 1 according to the invention causes

that the flywheel masses 2 change their center of gravity distance r and thus their orbital speed v twice during one orbit, so that a directed centrifugal thrust F _s is created, which can be calculated based on the centrifugal force law:

F _s = m _sl · &ngr;&khgr; ² /Γδ - m _s2 * v ₂ ^z /r ₂

m _s = k · m

k = coefficient greater than 2 depending on the respective track loop radius as well as distances and positions of the flywheel masses in the angle range α of the respective track loop,

m = mass of a single flywheel 2 .

If the preferred path-loop diameter d ₀ is the same , then simply:

F _s = m _so · ω ² · ( ri - r ₂ )

ω = V ₀ / r ₀

r ₀ = d ₀ / 2.

The centrifugal forces V acting against each other in the angle range β = 68 ° neutralize each other,

while in the angle range a = 112° differential thrust forces act in the thrust direction F _s ;

Thus, each flywheel mass 2 that passes through the angle range a = 112° forms a continuously increasing and decreasing resultant curve, which is superimposed on the resultant curves of the other flywheel masses 2 in this angle range a , which ensures an almost continuous thrust force F _s .

The guide track 1 is suspended from the (only schematically indicated) housing at three points via a circumferential rib, namely

At the bottom, the protruding rib is connected directly to the housing and above the track crossing point indirectly to the housing through a pipe 11.

The guide track 1 can rotate to the left or right, so that when arranged in pairs, undesirable side thrusts are neutralized.

The orbital twisting always runs continuously in the given direction of rotation, and the twisting angle is the same everywhere,

also on the straight connecting sections between the track loops.

For a jam-free roller run, the roller carriages 3 are set at an angle η against each other,

namely by bevelling roller carriage connecting plates 6 on both sides:

λ = X · 180° / L _B · 2

X = roller distance

Lj$ = guide path length .

Each flywheel 2 is pivotably screwed to the roller carriage 3 with two bolts 7.

In order to keep the flywheel 2 in the middle position, eight springs 8 are alternately connected to the connecting plate 6 and the flywheel 2.

The acceleration and deceleration forces that arise from the constant change in speed of the flywheel masses 2 are neutralized by the tension or compression elements that connect all the flywheel masses 2, here the rope 5.

However, in order to keep the load on the connecting elements as low as possible, the acceleration or deceleration path is extended by the movable mass suspension between the springs 8 and thus the load is reduced.

Fig.3

shows an alternative to spring suspension,

by replacing the springs 8 with high-energy permanent magnet strips 12.

The permanent magnet strips 12 are arranged in such a way that their force field holds the flywheel masses 2 in the middle position and enables a wear-free, two-sided compensating stroke. However, with this design, elastic stroke limits (not shown) are useful.

In order to increase the adjustment force, the permanent magnet strips 12 can also be arranged so that the repelling poles act on each other head-on.

Fig. 1 and 2 :

An electromagnetic primary drive for the flywheels 2 resembles a cut open and stretched squirrel cage motor,

wherein cages with armature rods 9 are attached to the roller carriages 3, while a field winding 10 is arranged stationary over the straight connecting sections of the guide track 1.

Fig.4

shows a modified embodiment of the
electromagnetic primary drive for smaller centrifugal drives.

Magnetic coils 13 are arranged in pairs one behind the other over the straight connecting sections of the guide track 1 and act on soft iron plates 14 on the roller carriage 3 by means of a known electronic pulse control (not shown).

The rotation direction Z is specified by a control clock I - V.

According to Fig. 4

one soft iron plate 14 was pulled to the center of the coil in timing position I, while the previous soft iron plate 14 reached the edge of the coil in timing position &Pgr; .

Now the magnetic coil 13 is excited in the clock position &Pgr; and the soft iron plate 14 is again pulled to the center of the coil.

This repeats until bar position V and then starts again in bar position I.

This creates a constant thrust movement of the flywheel masses 2, which ^

can be continuously adjusted according to the electronic control impulses.

- &iacgr;&ogr; -

While the thrust force can be used directly in vehicles, the generation of electrical energy requires the detour via a rotating movement.

Fig.5

shows in two views an arrangement in which

eight centrifugal drives according to the invention 16

are mounted on two counter-rotating axles 17 and 18 and drive four generators 20 via a planetary gear.

This arrangement shows how even with slowly rotating cross-axles 17 and the required high output speed can be achieved.

The upper cross-axle 17 acts via an internal gear ring 21 and the lower cross-axle 18 via a web 22 on a gear 23 and further via a gear 24

on a drive shaft 25.

The power is distributed via a bevel gear 26 via a reduction gear 27 to the four generators 20,

which enables flexible adaptation to the required performance.

Two centrifugal drives 16 each generate the torque for one generator 20 and form the smallest unit in this arrangement.
