Abstract
A thrust producing device comprises a support (10) to which torque can be applied. A cross member (13) fixed to the support carries rotors (17) on axels (16), the axles being pivoted to the cross member. When the torque is applied with the rotors spinning a thrust is developed.
Description
IMPROVEMENTS IN OR RELATING TO A PROPULSION DEVICE
DESCRIPTION
This invention relates to a thrust producing device in which angular momentum is converted into a linear force for, inter alia , propulsion.
The device of the invention does not require the presence of a fluid medium in which, to operate and the generation of the linear force is from a rotating mass.
According to one aspect of the present invention there is provided a thrust-producing device comprising a mass arranged to rotate about an axis of rotation that is denied the point about which it demands to precess, and is thereby constrained to translate the said point to a position where the precession does occur about said point, the translation producing a linear force.
According to a further aspect of the present invention there is provided a thrust producing device comprising a support extending substantially orthogonally from and rotatable about a first axis, a rotatable mass on an axle, a pivotal connection between the axle and a position on the support spaced from the first axis and means for imparting torque to the said support about the first axis, the arrangement being that when the support is mounted to allow the rotating mass to precess about the first axis and the torque aplied the axle carrying the rotating mass moves about the pivotal connection and a thrust in the direction of the movement to the device as a whole may be developed.
Preferably there is a plurality of rotating masses and each mass may conveniently take the form of a wheel or disc essentially providing a rotor of high goodness factor, being defined as reactive momentum real momentum
Generally the major portion of the mass will be in the periphery of the rotor.
Each of said masses may be arranged in opposition with an identical mass and rotated in opposite directions of rotation at substantially the same angular velocity.
Where a plurality of masses is deployed a dynamic balance is important to the success of the propulsion device.
The invention will now be described by way of example and with reference to the accompanying drawings wherein:-
Figure 1 is a schematic representation of a rotatable disc mounted to allow precession;
Figure 2 is a perspective view of a thrust-producing device in accordance with the invention;
Figure 3 is a schematic view of the device of Figure 2;
Figure 4 is a schematic view to show how dimensional differences in the device of Figure 2 influence the thrust .
Referring initally to Figure 1 a rotor disc R has a centre mounted for spinning about axis X1X2 on a shaft S1S2. Let us first consider the shaft S1S2 as being capable of pivoting about vertical axis Q1Q 1
and horizontal axis P1P2 . The disc R is spun and the shaft S1S2 carrying it rotates, i.e. precesses, in
the .direction PR1 about the axis Q1Q1, this precession being initiated by a torque. When a torque T1T2 is ap¬
plied to the shaft in the rotational sense of precession about axis Q1Q1, the shaft rotates about P1P2.
Precession is taking place about N1 i.e. about the
intersection of the axis of rotation of the shaft, the axis about which the torque is applied, and the axis about which the shaft can precess.
If, therefore, the torque axis is transferred to the point N2 on the intersection of
Q2Q2and P3P4, and X1X2 and the torque applied as
before about Q2Q2 then the shaft will precess about N2 pivoting about P3P4.
This principle holds good even if torque is applied about points N3 and N4 spaced from the axle.
From the above it can be perceived that an axle will precess about an axis orthogonal to both the axis of rotation and the axis about which the torque is applied at the point where these two axes intersect.
An embodiment of the invention is illustrated in Figure 2.
In Figure 2 a propulsion device of the invention comprises an axle rod 10 with a longitudinal axis Y1Y2 and is arranged to be able to rotate in high quality low friction bearings 11, 12. These bearings permit longitudinal movement to allow thrust produced to develop a working stroke. The axle 10 carries at one extremity an orthogonally disposed cross member or support 13 rigidly fixed to axle 10 as
by welding (not shown) . The cross member 13 has slots 141142 and pivots 151152 that are normal to the orthogonal line Z1Z2 of the cross member 13.
To these pivots 151152 are attached axles 161162 respectively terminating in free running rotor discs 171172 that spin in opposite directions as shown by
arrows on the discs per se . If a torque T1T2 is now applied to the axle 10 then, from the exposition given above in regard to Figure 1, since the axis Y1Y2 about which the torque is applied
cuts the axes Z1Z2 of both rotors, 171172 in point N5, precession should take place about an
axis through N5 in the plane N4 P9 P101 where P91P101 is
parallel to axis P9P10 through pin 151. (It is the same
mutatis mutandis for pin 152) ; but the construction is such that this is not possible without a movement of the whole device in the line Y1Y2 such that the point
N5 is made the apex of a frusto-conical volume shown
by the dotted circles in Figure 2, the radius R1 and
the generator G1; the rotors 171172 rising
(or lowering) as the resultant forces dictate to the dotted positions shown at 17' 117' 2 to bring said apex
A coincident with N5. The identical integers of
Figure 2 with identical references are shown in Figure 3 for greater clarity. The movement of the whole device is along Y1Y2 in this instance in the direction of arrow Y3. If the motion along Y1Y2 is resisted by frictional forces or by gravity which generally is to be expected, the axle 10 will rotate under the applied torque, work will be done and an energy balance produced. It is to. be appreciated, however, that in the form of the device shown in Figures 2 and 3 when the rotors 171172 move to positions 17' 1 and 172 ' the cross member 13 moves not as is to be expected, in opposition to arrow Y3, but
with it in the same direction and matter is moved without reaction and a propulsion device is established.
To provide for continuous propulsion a multi-phase device is essential with a separation of the phases as in an analogous electrical machine.
In Figure 4, it can readily be seen that if the distance 11 (see also Figure 3) be increased to 12
then the apical distance of the fulcrum is increased from a1to a2. Similarly if the torque T1T2 is increased in amplitude then the angle α1 will increase
to α2.
