Abstract

A centrifugal dynamic drive engine comprising: a rotatable driven shaft A; and an arrangement of actuators B and counterweights D located on a bearing C on the shaft A. When the shaft A is rotated at speed, the centrifugal forces exerted on the shaft A by the counterweights D can be increased or decreased by the actuators B. The actuators B can pull either one of the counterweights D inwards into a smaller arc and increase the force on the shaft A in that direction, or let either one of the counterweights D move outwards into a larger arc and thus lower the force on the shaft A in that direction. When the actuators A are operated in the desired sequence the result is a net force on the shaft in a specific direction to propel a vehicle in a desired direction.

Description

DYNAMIC DRIVE ENGINE

This invent ion relates to an engine whose propulsive force is dynamically generated.

There are many types of engine to propel vehicles that are designed to perform various functions and these engines can be roughly divided into those that expel burnt chemical fuel from the engine to obtain thrust, i. e. rockets, jets,ion thrusters, and those that push or pull themselves along by using dnve wheels, propellers,tracks, etc like internal combustion engines, steam engines,and electrically driven vehicles.

The major disadvantage of the rocket "type" of engine is the large quantity and physical bulk of the fuel required (to be carried) for a long journey,and other types of engine need a surface or atmosphere to push or pull against for their propulsion.

According to the present invention, a form of flywheel is constructed whereby the flywheel mass is fixed to the shaft by actuators that manipulate the centrifugal force acting between the masses (or counterweights) and the shaft as they rotate in such a way that a controllable unbalanced force is generated to propel the craft.

The main advantage of this invention is that this drive motor does not need to expel mass, or to have a medium to work in i.e. the atmosphere, or to have another mass to push against to obtain motion.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which:- Figure 1 Describes parts of the basic engine, side and plan elevation.

A=Shaft. B=Actuator C=Beanng D=Counterweight E=Drive motor F=Casing Figure 2 Shows two counterweight actuator assemblies revolving counter clockwise to each other, and synchronised 1:1.

Figure 3 Shows a sequence of the assembly moving through 180. Degrees.

Figure 4 Describes the force vectors on the shafts while in drive mode.

Figure 5 illustrates the positional return of the counterweights to their balanced states.

Referring to figure 1: The basic engine consists of masses or counterweights "D" that are fixed to a central shaft "A" via actuators "B" that can pull the counterweights closer to the shaft, or allow them to move away under centrifugal or generated forces.

escnDtion In this descnption two flywheel assemblies are shown working together, revolving counter clockwise, and synchronised 1:1 this has the effect of linearising the drive forces generated so that the craft moves in a linear trajectory.

Referring to figure 2: The shaft counterweight assemblies are first revolved by the drive motors to generate centrifugal force (X) between the counterweights and the shaft with the actuators holding the counterweights in positions where the centrifugal forces are equal and the assembly is revolving in a balanced state.To initiate the generation of a propulsive force from the engine to propel the craft, the actuators are activated as follows.

Referring to figure 3,.a.b.c.d When the counterweights enter the shaded area its actuator is instructed by a control circuit (not shown) to increase its "pull" on the counterweight thereby moving it into a tighter or smaller arc, at the same time the counterweight opposite stays at the same distance and force. This means that during this half revolution of the drive, the shafts (that are fixed, through bearings, to the craft) have a greater force on them on the (shaded) Side where the counterweights are being pulled in, than on the opposite side. figure 3 d. shows the positions of the counterweights after one half revolution, with the path of the counterweight with the extra "pull" applied, shown by the smaller dotted curve.

The larger dotted curve shows the path the counterweight would have taken if it was inactivated.

fiure4: Shows the force vectors operating during this period and it can be seen that there are greater forces on the shafts in direction (F) i.e. the centrifugal force (X) plus the extra force needed (N) to pull the counterweight in to a tighter arc, than are operating in the opposite direction due to the centrifugal force alone.

The resultant net unbalanced forces on the shafts (and therefore the craft) have the combined effect of moving the craft in direction (F) during this half cycle.

The dynamic drive is now in the position shown in figure (5) and the counterweights that have been drawn into a tighter arc,(shown in dotted lines) are "released" (shown in sequence 5.a.b.c.), and returned to their original positions As they are released the forces generated by the counterweights are equal and opposite and effectively cancel each other out.

The next pair of counterbalances are now in position and ready to carry out the sequence again.

It can be seen that the dynamic drive is an engine that propels itself by internally generated forces that can act to move a vehicle in a linear trajectory. 3.

Claims

1. A dynamic dnve engine comprising masses or counterweights fixed to a shaft via adjustable actuators with means provided to revolve the counterweight I shaft assembly at speed so that the centrifugal forces on the shaft can be manipulated by the actuators to produce an unbalanced force which produces propulsive dnve in the desired direction.

2. A dynamic drive engine as in claims 1, wherein the counterweights are returned to their balanced positions as they oppose each other in rotation after the first 180 Degrees, whereby their opposing forces can cancel each other out.

3. A dynamic drive engine as claimed in claim 1 wherein means are provided to initiate the propulsive cycle at any point in its 360 degree rotation.

4. A dynamic drive engine as in claims 1 & 3 whereby as the first counterweights are pulled in the opposite counterweights are allowed to move out so that in the next part of the cycle the counterweights are reversed, so producing another pulse of force, and returning the counterweights to their original positions.

5. A dynamic drive engine as in claims 1 /2,3 & 4 wherein the counterweights are operated in reverse mode.
