Abstract

An axis a is pivotable about a centre of action P and the masses e may be moveable around a common centre x. The axis a is adapted to slide in controlled fashion across the pivot P in either direction y as required. The figure marked "map" illustrates the position of one mass element e or e1 as it progresses through one cycle. The mass element e or e1 approaches P axially between positions 1-6 as the axis rotates. Positions 1-2, T, denote the "thrust" sector which denotes a phase of enhanced axial transit toward P. Whichever mass element e or e1 is in anti-phase at this time will experience an equal and opposite axial movement away from P. It is stated that, as one element mass approaches P in one half part so whichever element is orbiting the other half part moves axially away from P, thus effectively decreasing its angular velocity in this area. These two actions yield an imbalance to give a linear uni-directional force. As one element mass slows down, due to a reduction in radius of action at axial approach, then the other will speed up as it moves out, thus angular momentum is conserved. Other embodiments are disclosed showing, for example, two counter rotating axles each having four mass carrying axles mounted thereon (diagram 2a); and, a system comprising a pivoting, in addition to a rotating, mass array (diagram 3, 3a and 3b).

Description

CENTRIFUGAL INGRTIAL PROPULSION SYSTEM DIAGRAM isadiagrammatic representation of the basic idea behind a previous submission by a Mr A Kidd.

It consists of a boom (b) attatched to and rotating about a mast (a). Gyroscopes (e) are affixed and pivoted at either end of the boom.

When the boom (b) is caused to rotate about the attatched mast (a), in the direction shown and the gyroscopes (e) are also caused to rotate in the direction shown (d) ; that is, the upper surface of the gyroscopes (e) in the same direction as the boom rotation. A force (F) is experienced in the direction shown.

If the boom (b) is continued to rotate but the gyroscopes (e) each have their directions of rotation reverse, then the force (F) is experienced in the opposite direction. for a force (F) to be experienced in the direction shown, boom (b) is imagined as an axle pivoted around it's middle, whilst the gyroscopes (e) are imagined as wheels resting on the ground. Whatever direction the axle is rotated, the resulting direction of rotation of the (wheels) gyroscopes (e) caused, would mean a force (F) being experienced in the direction shown.

DIAGRAM (2) :- This is a diagrammatic representation of a structure, comprising a single axiom (a) with equal masses (e) positioned at either end.

The axiom (a) can. Toe pivoted about a centre of action (P) that the (e) masses can be made to move around a common centre (arrow x The axiom (a) can be made to slide, in controlled fashion across the pivot (P) fn either direction- as required.(y).

DIAGRAM(a.):' shows two counter rotating axles (x) each containing four systems as described in diagram (2) ~ The four systems are 1/4 rotation phase shifted along the asles (x) Xach system is also matched by phase on opposite axles (x) O.

This arrangement eliminates stray forces by counterbalance and when driven up to a working speed will give smooth, continuous uni-directionn1 fbrce There are a number of ways of constructing this system from an engineering point of view, for example, use of gears, Thomson bars & worms, hydraule= etc. The engineering minutae are not at issue at this stage as long as any derived system is driven and coordinated according to the principles outlined here..

DIAGRAM (2) MAP:- This is a diagrammatic representation showing the disposition of one element mass (e or (e1) as it progresses through one cycle (P), as iiagram (2 is the pivotal centre of rotation. The element (e or e1 approaches (P) axially between positions (1-6) as the axiom rotates. Positions (1-2)denote(T)the"thrust"sector which denotes a phase of enhanced axial transit toward (P) > Whichever element (e or e1) is in anti-phase at this time will experience an equal and opposite axial movement away from (P) o DIAGRAM () Each of eight axia (S) are hinge mounted and equally distributed around a small wheel structure which is pivoted at a centre of action- (P) o. Equal masses (e) are appropriated at the ends of each o the axia (S) The end-of axia (e) is also a rotating pivot for a further mass (e1) which rotates about (e) at the end. of a perpendicular extensiom arm (x) and in the same direction of motion as (e) ; direction (d1) shown. Note, the angular motion of (e1) corresponds 1: 1 with the rotation of (e) about (P).

The situation of two of the eight hinged and pivoted masses is approximated in diagram (3) (side view) ; those diametrically opposite each other on the pivot wheel (P) Noter the two masses (e) shown are at either end of their respective limits of out of plane actions about hinge (h).

DIAGRAM (3a) Illustrates a complete element system shown from the front.

The presence of components (e1) are assume, otherwise lettered designations are the same as for diagram (3) zip Note, on cycle of the main system (elements (e) about (P)) corresponds to one cycle of elements (e1) about their respective elements (e): 180 positions shown in diagram (5) > DIAGRAM(3b) A complete working structure would consist of two counter rotating axles (a) with an element system at the end of each axle (four off), centres shown (P). This is again intended to eliminate stray forces by counterbalance and to facilitate smooth production of force, Note, that a method of controlling and coordinating the axle (a) rotation (r) (as (d)), the rotation of arms (x)that is (dl) and the-motion of the hinge (h) will need to be engineered.

The technology already exists to do this in a variety of ways as long as the essential principe is ad hered to and that is all that. needs to be at issue here.

An efficient system for converting the powerful and easily generated centrifugal force into linear force. Such a system would find extensive use in all areas of the transportation industry. Most promisingly, on both the very large scale and the small scale it would. be useful in spacev Most particularly it lends itself easily to being powered atomicallyo There have been many examples of linear force generation from centrifugal systems occuring accidentally, a smooth efficient way of expressing this force has however so far evaded inventors.

The first and only to a working device was a Mr A Kidd, however efficiency was the problem (less than 1% I calculated) see diagram (1).

Corresponding rotations of. boom and gyroscopes as shown, increases the effective surface speeds at the periphery of half of each gyroscope because the effective distance travelled is enhanced by the compounded movements. The vector is subtended by a fraction of the circumference of the gyroscopes travelled over unit time in the plane of their action and the corresponding out of plane movement caused by the boonL over the same unit of time. (By Pythagoras, Ealculating from the in plane distance around, the circumference, of the gyroscope and-the circumferential distance moved at a right angle Bansei by the rotation of the boom ; the effective increased travel tramez about because the resultant vector is. as circumferential hypotenuse to these two components.) The output of this system is small when compare to the input, despite an equal and opposite reduction in circumferential velocity in the opposite part of the. gyroscope cycle to the one considered, above : which further enhances the constant inbalance and force from the system.

The inefficiency of this system is caused because of the large effort required to continually twist the rotating gyroscopes out of their plane of action, by movemat of the boom.

This new submission is designed to overcome this lack of efficiency. Calculations derived from basic theoretical constructs point to efficiencies of well over 60% and this could. be improved still. further-by various adjustmen 4s a fL-nough the use of centrifugal inertia remainss the method of achieving efficient coversion of energy is different and this constitutes a very new inventive step in this axea., The Kidd system utilises an effective increase in circumferential travel created in one half of travel of a rotating gyroscope. Effectively an increase of radius of action in one direction The system outlined in this submission utilises an iobalaimee caused by an effective difference in angular velocity between opposite directions.

From a detailed analysis of a large number of possible systems two different expressions, one more efficient than the other emerged as useful.

Both new systems represented here have forsaken the gyroscope for singular mass elements. Although in any working system multiplication of element systems to achieve smooth force delivery and to balance out and eliminate stray forces would effectively contain a ring of singular elemental weights.

(Please refer to diagram (2) map and the key note on the support sheet).

The constraining of a rapidly moving element mass against it moving away from (P) at a tangent is what causes the force on (P). This force is In* to velocity of the element in relation to (P) and its angle of"approach"to (P). The "standard approach"of (e}-the element to (P) will be at constant radius or"pitch"against tangential movement. Movement of (e) toward (P) axially will increase the angular velocity of (e) about (P) Axial movement of (e) away from (P) will have the effect of decreasing the effective angular velocity of (e) about (P).

Utilising a two element unit with correct coordination of rotation and axial transit; increase in angular velocity could be achieved in one half part, with a corresponding decrease in the other Further, with a two element unit as the peripheral velocity of one element slows, so the other speeds up; thus angular somentum is conserved Calculated efficiencies in excess of 60% have been noted for this system; this could also be very much improved on with some fine tuning.

(In real terms the basic system will lift ~more than 1000 Kg per tOO BP applied ;)..

There is the possibility as previously mentioned of another expression of the same principe, that of a cyclical action containing a variable angular velocity. This systems variation comes about through variation outside the plane of rotation.

NB/The inefficiency of the out of plane manoever is very much reduced in the followingsystem,becauseittakes place in two directions and not. one ; (as with the Kidd system) also it is not continuous at maximum pitch but impulse which is also balanced in two directions.

(note feature es optional and is factored in to assist initiation of out of plane action.) It can be seen from diagrams (3) that each element mass has two centres of action, one in plane about (P) and one out of plane about (h) o By correct synchronisation of these two actions angular velocity can be varied in the two half parts In this system the element (e) alternates between fast out of plane movement about (h) and slow out of plane movement.

The angular velocity of the element (e) during the slow out of plane phase is greater than during the faster out plane motion. (During the slow phase out--'-of plane action can be all but stoppedO) NB/Extra out of plane motion is always effectively movement away from (P) thus reducing effective angular velocity.

In summary-A full centrifugal moment in one half part; of little out plane motion and in the other part there is negligable moment due to out plane action and little effective in line pitcht
