FIELD OF THE INVENTION

[0004] This Levitation and Propulsion Unit - Four (LPU-4) is a thrust generating invention in the field of inertia propulsion. Inertia propulsion is propulsion without mass ejection and/or momentum exchange, unlike all current propulsion technologies. This classification of propulsion is generally deemed not workable or not feasible. Thus, less explored, and at its infancy.

The wheel module is capable of creating a resultant thrust as the result of the magnetic pulsating repulsive force and the rotation of the main wheel and the flywheel. However, due to the transfer panel component being incorporated in a floating manner and the electromagnet separated from the transfer panel, these limit the invention function to generate rapid and higher resultant force efficiently.

This new version, LPU-4, the objective to enable higher and faster efficient inertia thrust generation of patent granted LPU invention.

BRIEF SUMMARY OF THE INVENTION

[0008] Patent granted LPU is an inertia thrust generating invention, it mainly generates internal impact impulse to create an internal resultant force, to create resultant motion, without external interaction, unlike current propulsion technologies whereby it involved mass ejection and/or momentum exchange. This inertia thrust generating technology primarily involves:

1. electromagnetic energy;

2. magnetic repulsive energy;

3. centrifugal force energy; and

4. kinetic energy; to generate resultant force without external interaction. The LPU’s technology leverages on compressed magnetic repulsive flux to convert an induced force from electromagnet and centrifugal force from spinning wheel into conserved energy, and at flux expansion, into driving action force, to mainly accelerate a mass, to generate impact force, to create a resultant force without external interaction. The process of resultant force generation in this Levitation and Propulsion Unit - Four (LPU-4), see fig-1, fig-2, fig-3 & fig-3b, is similar to patent granted Levitation and Propulsion Unit (LPU). In this LPU-4 - fig-1, resultant force generation still include the main components but less transfer panel: strike panel with electromagnet; flywheel; sliding angular couplings; and main wheel.

The improved features incorporated in this LPU-4 design are:

1) Integrated design of plunger assembly fig-7 with transfer panel 06, wherein it is not connected in patent granted LPU invention. The purpose: a) To create a rigid connection to enable stable action and to enable transfer panel magnet 06 closer to stator coil 08 for faster and more effective coil 8 and magnet 06 interaction. b) The design also enables the plunger assembly to deliver impact at two area to create resultant motion - see fig-1 & fig-7, where is one area in earlier invention c) The design includes connection shaft 12 with plunger assembly fig-7 to enable installation of sensors, mainly optical and /or hall sensors, to determine precise position of plunger assembly - see fig- 1. ) The design incorporates features to increase the kinetic energy of a mass in motion - plunger assembly fig-7. To enable higher generation of resultant force. a) Provision added at mass 18 at the plunger assembly - see fig-7 ; and b) Incorporation of high flux density permanent magnet type in the assembly which is much heavier than normal permanent magnet to further add mass and similarly enable faster plunger response. ) More efficient design of electromagnet device to increase magnetic flux interaction between each magnet and each stator coil to enable higher driving force and longer plunger assembly fig-7 travel. This, to enable higher compression at compressed magnetic repulsive zone 05 to create higher magnetic repulsive energy -see fig-2, fig-3 & fig-3a. a) Magnets 06 and 10 are arranged outside one stator coil 08; b) Each magnet of different size and strength - see fig-7 ; c) Each magnet arranged with same pole facing each other in the plunger assembly - see fig-1 & fig-7. This enables very effective use of both attraction and repulsion forces at the same time between one energized stator coil 08 with two magnets. Which enable relatively smaller stator coil size, lesser current input to coil and less heat from coil, hence lesser or any opposing coil field at upward phase of cycle, to enable rapid action; d) No ferrous material in stator 09 and plunger assembly fig-7, to remove or reduce hysteresis issue from components to lower hardware latency, to improve electromagnet response time; e) Design enables addition of high flux density magnet at magnet 06 and/or magnet 10 at end of plunger shaft 07 by extending bracing rods 15, plunger clamp 11 and clamp lock bolt 21, - see fig-7, to further increase the magnet strength and mass of plunger assembly. This enables plunger assembly fig-7 to make relatively longer travel without increase in current input to stator coil 08. Thus, enable further compression of compressed magnetic flux zone 05 to create higher potential energy to increase thrust at upward phase of a cycle. ) The material of plunger shaft 07 and stator 09 - fig-1, fig-6 & fig-7, of non- ferrous material like aluminum, titanium, stainless steel, brass, polymer, alloy, composite, plastic, ceramic or likewise materials; to mainly reduce hysteresis issue to lower system latency. This improves the electromagnet response time to function rapidly.

DETAILED DESCRIPTION OF THE INVENTION

[0025] LPU-4 is an inertia thrust generating invention which the technology primarily uses electromagnetic energy, permanent magnetic repulsive energy, centrifugal force energy and kinetic energy, to generate internal resultant thrust. The technology leverages on compressed magnetic repulsive flux to convert an electromagnet induced force and centrifugal force from spinning wheel into conserved energy, and back to driving force, to accelerate a mass to generate impact force, to create a resultant force without external interaction. This Levitation and Propulsion Unit -4 (LPU-4), see fig-1, of cylindrical profile configuration is the preferred embodiment- 1. The main components layout is similar to patent granted LPtl. The difference is at the electromagnet, where the transfer panel 06 component of patent granted invention LPU now integrated into the electromagnet’s plunger assembly fig-7. The electromagnet functions are similar to the electromagnet in strike panel described in specification of patent granted invention - Levitation and Propulsion Unit (LPU). At downward phase, the electromagnet energized to repel or move transfer panel 06 to further compress magnetic repulsive flux 05. Which in this LPU-4 design, the plunger assembly fig-7 now includes the functional role of the transfer panel stated in specification of patent granted LPU invention - to transfer the exerted force from electromagnet on to the spinning fly wheel 27 at downward or compression phase, and to deliver the impact on the strike panel 14 at upward or expansion phase. Other main components like magnets, flywheel, sliding angular couplings, main wheel and variable speed motor, basically function as stated in the patent granted LPU’s specification in this LPU-4 invention. The major difference is at the improved design of electromagnet and integration of the transfer panel into the plunger assembly enable rapid action of cycle and higher resultant force generation.

[0026] The material of components mainly of non-ferrous material like aluminum, titanium, stainless steel, brass, polymer, alloy, plastic, carbon fiber, ceramic; or ferrous materials, ferromagnetic; or composite of materials or other equivalent materials, to meet each component functional and structural requirement to meet LPU-4’ s application and device requirements.

[0027] The LPU-4 technology leverages on compression and expansion of compressed repulsive magnetic flux. The compressed magnetic repulsive flux function as the medium in potential energy source and conservation of energy; the energy to accelerate a mass - plunger assembly fig-7 mass, to create impact in generation of resultant force. In this preferred embodiment- 1 , fig- 1, the compressed magnetic repulsive flux zone 05, between magnet 06 and fly wheel 27 function as potential energy sources and conservation of energy. The level of compressed magnetic repulsive flux at zone 05 at default stage or at design stage depend on the amount and frequency of resultant force generation to meet application, in addition to other parameters, like - plunger assembly mass and magnet 06 width, current, coil, magnets, device space, etc. [0028] LPU-4’s basic operation cycle comprises downward or compression phase and upward or expansion phase in a cycle. Fig-1 to fig-3b, which illustrate each main component status at each phase of a cycle. Before the cycle starts the motor 46 starts spinning to spin main wheel 47. The main wheel 47 is connected to a fly wheel by more than one sliding angular couplings via slide supports 48. The slide supports are connected in radial pattern away from the axis of main wheel 47- see fig-4. The number of sliding angular couplings also dependent on the size of fly wheel 27 which depends on application requirement. The spinning main wheel 47 generate centrifugal force. As the spin rate increases, the increase centrifugal force pushes the fly wheel 27 upward to further compress the already compressed magnetic repulsive flux zone 05, which further increases the level of potential energy in zone 05 - see fig-2.

[0029] The cycle starts with downward phase which energizes stator coil 08 to create coil polarities wherein coil 08 “north” is nearest to magnet 06 and coil “south” is nearest to magnet 10, as reflected at fig-2. This coil 08 status creates repulsion force between coil 08 and magnet 06, and attraction force between coil 08 and magnet 10 to pull magnet 10 into stator 09 which together create the driving force to move the plunger assembly fig-7 downward to further compress magnetic repulsive flux zone 05 - see fig-3. At upward phase, the current polarities to coil 08 that induced the driving force is reversed momentarily wherein now coil 08 “north” is nearest to magnet 10 and coil “south” is nearest to magnet 06, see fig-3 A. This coil 08 status creates attractive force between coil 08 and transfer 06, and repulsive force between coil 08 and magnet 10 which together momentarily create a pull-up force momentarily on the plunger assembly with magnet 06 upward, to mainly overcome its inertia. And thereafter, current to coil 08 switch off. In condition where there is sufficient strong potential energy at compressed magnetic flux zone 05 at end of downward phase, relative to the thrust and frequency to generate, inertia of plunger assembly with magnet 06 to overcome and other parameters to assess, no momentarily reversal of current needed. Then, current to coil 08 is switch-off once downward phase stop. The highly compressed magnetic flux at zone 05 immediately expand, due to no driving force or low pressure at A2 - see fig-3B. The flux expansion force accelerates the magnet 06 and connected plunger assembly fig-7 upward to impact strike panel 14 to create the resultant force. At the same time, at start of upward phase, the motor to generate pulse spin to create a momentarily generation of centrifugal force to push flywheel 27 upward, to push the expanding flux upward - to direct the flux expansion at zone 05 to act more on the plunger assembly. To reduce the expanding flux to act downward on flywheel 27 which can create drag against the intended direction via impact momentum. The expanding flux thus drive the plunger assembly fig-7 to impact the strike panel 14 to create resultant force.

[0030] Alternatively, the system can create resultant motion via flux expansion from the expansion of compressed flux at zone 05 if the motor does not generate pulse spin to create a momentarily generation of centrifugal force to push the fly wheel 27. The flux expansion instantly acts on the flywheel 27 once the downward phase stops. The flux expansion instantly pushes the whole device in opposite direction to the direction create by impact force. At the same time the flux expansion also acts on the magnet 06 of plunger assembly fig-7 to push it to impact strike panel 14. The opposite direction motion created by flux expansion stop once plunger assembly impact on the casement member 14. This opposite direction resultant motion is by flux expansion. This opposite resultant motion does not carried momentum unlike the motion by impact force from plunger assembly fig-7 created by momentarily generation of centrifugal force which push flywheel 27 to direct the flux expansion upward. The resultant motion via flux expansion is mainly in step motion per cycle - step by step, no continuous motion or momentum like via impact force. In zero environment, like in Space, this duo directional resultant capabilities are useful.

[0031] At the electromagnet, the amount of induced driving force on the plunger assembly mainly depends on the magnetic flux density and flux spread of magnet 10 and magnet 06 in relation to coil 08 layout, its energized electromagnetic flux density and spread. At device design stage, amongst other parameters, need to determine the maximum amount able to drive plunger assembly fig-7 to further compress the already compressed magnetic flux zones 05, to optimally conserve the energy in the form of compressed magnetic flux at zone 05. And, at upward phase, able to create the needed energy at flux expansion to accelerate plunger assembly fig-7 to generate the resultant impact force.

[0032] At downward phase or compression phase, as the energized coil 08 induced a driving force to move the plunger assembly downward, there is an equal opposite force acting on the coil 08 to move upward or opposite direction - Newton 3 ^rd law: action = reaction. The coil 08 is connected to the strike panel 14 and application, therefore, the reacting force move the whole device and its application upward or opposite direction to the plunger assembly fig-7 motion. In gravity environment, if the induced force is sufficient, the reacting force creates a momentarily lift or motion, and it stop once the induced force stop, and gravity pull it back down at nominal rate 9.84m/sec square. In gravity environment, the amount of lift or opposite motion to plunger assembly fig-7 motion depends on the mass of the device and its application. Against gravity, if the reacting force is not sufficient to create motion, the reacting force which also acts along the force path and area around coil 08 connection, can flex or deform the material - dependent on elasticity of the material and/or structure. Therefore, the device structural adequacy and suitable electromagnet are needed to meet functional requirement to meet application requirement. In zero gravity environment, the reacting force can move the device and application in opposite direction to the plunger assembly fig-7 motion, and the motion stop once the plunger assembly fig-7 motion stop.

[0033] To create continuous motion, it is similar to multi-stage rocket - previous impact momentum supports the next stage generation of impact momentum. In gravity environment, if the frequency of an impact resultant force is faster the gravitation acceleration, the lift or motion created by reacting force at downward phase of a cycle can continue with the impact momentum at upward phase of the cycle. Therefore, in gravity environment, to create airborne propulsion and levitation functions, cycle frequency higher than gravitation acceleration and sufficient resultant force generation in a cycle to meet application requirement are essential. In zero gravity environment, cycle frequency and resultant force sufficiency may not be essential to create motion, continuous motion and etc.

[0034] This Levitation and Propulsion Unit -4 (LPU-4), resultant force generation is mainly through regulation and systematic control of current to coil of electromagnet to move plunger assembly fig-7 and control of motor spin, to create the desire resultant motion and motion direction.

[0035] This Levitation and Propulsion Unit -4 (LPU-4) applications mainly in mobility propulsion on Earth and in Space. It can complement or supplant current propulsion technologies. The layout of main components is scalable to meet application requirement. And, the design of this LPU-4 is scalable and/or apply in combination of more than one unit to meet application requirement. Further, there can be more than one electromagnet to induce force on one flywheel to meet application requirement.

[0036] As described at para [0027] to [0029], the LPU technology basically leverages on compression and expansion of compressed magnetic repulsive flux to accelerate a mass to create impact to generate a resultant force motion. Alternatively, as described at para [0030], the technology can also create resultant motion in opposite direction to impact resultant motion direction by leverage the expansion of compressed magnetic flux only without motor pulse acceleration to generate momentarily centrifugal force to push the flywheel 27 at end of downward phase of a cycle. Therefore, the control of compressed magnetic repulsive flux expansion determines the direction of resultant force motion. There are also various devices to create the exertive force to further compress the compressed magnetic repulsive flux to create the potential energy for flux expansion. The suitability of such devices depends the function and its response time to meet application requirements - to defy gravity, response time need to be faster than gravitation acceleration.
