DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Aspects of the invention are disclosed in the following description and related drawings directed to specific embodiments of the invention. Alternate embodiments may be devised without departing from the spirit or the scope of the invention. Additionally, well known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention. Further, to facilitate an understanding of the description discussion of several terms used herein follows.

[0031] As used herein, the word “exemplary” means “serving as an example, instance or illustration.” The embodiments described herein are not limiting, but rather are exemplary only. It should be understood that the described embodiments are not necessarily to be construed as preferred or advantageous over other embodiments. Moreover, the terms “embodiments of the invention”, “embodiments” or “invention” do not require that all embodiments of the invention include the discussed feature, advantage or mode of operation.

[0032] Now referring to exemplary FIG. 1 showing an eAircraft with all its parts from a top view. The aircraft may have two stabilizers on each wing 101 and several flaps 111 on the rear central part of the wings. There may be 4 dielectric elastomer power generators (DEGs) 107 above, two wind turbines 109, and an electric jet turbine 108. There may also be an additional source of power generation on board of the aircraft 113, which may be a rotational electromagnetic power generator. All power generating devices are on the top of the central plane surface 110 with a possible exception of the electromagnetic power generator 113 that can be placed inside the body of the aircraft together with a central electronic unit underneath the cockpit 103 that controls the whole functioning of the power generation devices on the plane in a most efficient and proper manner. The wings of the aircraft may or may be just plane surface or planted with solar microlenses as shown below in FIG. 1A alternative solution.

[0033] Now referring to exemplary FIG. 1A, this figure shows this high concentration solar cells embodiment 30 which may be implanted on aircraft's wings in FIG. 1A below.

[0034] The structure making the surface of the wings 112 of the eAircraft can be concentration lenses 31 made of multiple micro lenses 32 and a high efficiency heat resistant solar cell 33.

[0035] The lens can be made of acrylic or bio-degradable plant lignin with possibly graphene oxide reinforced or any other favorable material able to resist high temperatures. The magnifying thickness of each lens 32 could be in nanometer or practically at the center of lens may have a thickness of 0.3175 cm and the thin film micro lenses has a width of 0.040 mm. The idea of the micro-lenses is inspired from nature: many insects eyes are made of pluri-lenses 32 in which light coming from all directions (almost 200°) is focalized on a single spot and here we focalize onto a solar cell 33 which may be made of gallium arsenide 33 (as for example a solar cell with highest efficiency developed by John A. Rogers in his paper published in Nature DOI: 10.1038/NMAT3946). Sunlight is thus intensified more than 200 times due to this magnifying effect as described in my solar house U.S. Pat. No. 9,350,290

[0036] Now referring to exemplary FIG. 1B, in which there is the same arrangement as in FIG. 1 with the wings of the aircraft covered with said solar microlenses 30. However, in this embodiment, the stabilizer of the aircraft may have a different stabilizer placed on the rear of the aircraft as been developed by the MIT team for the NASA as described above also.

[0037] Now referring to exemplary FIG. 2, the aircraft is shown in a front view as described in FIG. 1 with its windows 102 and seats placed inside the wings for efficiency reasons. The aircraft may have three sets of wheels for its stability a pair at the front 105 and two sets at the back 104 and 106 respectively

[0038] Now referring to exemplary FIG. 2A, this figure shows another possible solution of the aircraft as described in FIG. 1.1 with the stabilizers maybe placed at the rear of the aircraft. There are two tanks under the belly of the aircraft underneath the luggage compartment space: one containing helium 191 and the other 192 atmospheric air. Additionally, there is also a gyroscope placed in the middle, as herein shown, of the plane. The first tank will be filled with helium gas and the second contains atmospheric air. However, the space compartment containing the helium gas may extend to also fill the space under the whole volume area of the wings (where kerosene or fuel may be stored in a traditional airplane) and can thus lift larger and heavier aircraft weight, along with carrying more cargo and passengers. The helium gas will give the eAircraft the uplift needed to start vertically upwards from the ground, as helium is lighter than air but only when the second air-tank is also empty i.e., when all the air inside second tank has been expelled or pumped out. Thus, the whole of the acceleration power needed for take of and/or landing may be not be needed. The gyroscope will have the function to keep the eAircraft always upright and well balanced, at all times. This special feature would allow the eAircraft to take off or land without consuming much energy for either accelerating or braking during take-off and landing.

[0039] Referring now to FIG. 3, a magnetic generator mechanism 113 may include at least one magnetic cylinder directed towards a magnetic blade 11 placed at the center of this mechanism-device which functions as a free rotating blade. Blade 11 may be made of magnetic cylinder material through which current at a precise moment and only for a very brief time period would be flown to magnetic blade 11 and simultaneously magnetic cylinder 10 similarly. Thus, magnetic cylinder 10 and magnetic blade 11 may be positioned with equal poles directed toward one another in order to produce a repulsion force between said tow once current from the battery 18 flows through coils in both blade and magnetic cylinder 10.

[0040] Magnetic cylinder 10 may be placed in this embodiment in such a way that its magnetic equal (+ve or −ye pole) force is substantially directed at the other magnetic blade 11. There may be a point in time in which the two magnetic cylinder 10 and 11 reach nearer to one another, referred to as the “point of incident” (PI). PI is the point in time when magnetic cylinder 10 and magnetic blade 11 come near enough to one another in order to repel one another and thus blade 11 may continue to rotate. Once blade 11 passes a critical point P, the magnetic force of magnetic cylinder 10 may drive blade 11 by repulsion in an anti-clockwise direction.

[0041] Blade 11 may be welded to a metal shaft 12 which may rotate in a circular motion as the blades set in motion by the force of the magnetic field exerted by the magnetic cylinder 10 upon blade 11. Around the central shaft there may be a stator (generative coil housing) which may produce electricity as shaft 12 rotates inside this stator. The shaft 12 is welded to said blades substantially at the center of this electromagnetic assembly or embodiment.

[0042] The magnetic field of magnetic cylinder 10 would only be magnetic at the moment blade 11 has just reached position C which is slightly downward to make sure that the current would flows only when blade 11 has passed critical position for the actual repulsion forces to take place also the contact point at which time only current would flow from battery 18 in order to magnetize both cylinder 10 and blade 11 to push it further into an ever faster accelerated angular motion There may be sensors, S1 and S2, each placed at critical positions, P1 and P2. The sensors would signal for each magnetic cylinder the critical position of blade 11. Once blade 11 has reached P1 magnetic cylinder 10. In case of a vehicle using second embodiment 10 will substantially all braking forces, if any here, and the work (energy) done by magnetic cylinder 10 and 11 in this system may be transmitted to this flywheel for storage and eventually rebooting the system from stored electrical power inside the flywheel or from an external battery 703. Thus, the blades 11 may then receive only the repulsion or “push-force” from magnetic cylinder 10 to continue its rotations in one direction at all times. The use of a flywheel as a storage mechanism and its application is a conventional state-of-the-art technology. Additionally, the rebooting of the system maybe also powered by the solar electric energy produced on the roof top 407 of vehicle and/or building of a power plant in order to keep the battery 18 charged at all times. Thus, the system is indeed an open energy system, from a thermodynamic point of view.

[0043] The whole system may be controlled and wired by an overall electronic central unit 704 which also controls other components of this device.

[0044] Additionally, all other components around the magnetic cylinders 10 and 11 may be constructed of a material which is non-magnetic and not attracted by the magnetic cylinders at all times. Such a material may be aluminum or carbon alloys which are very hard and resistant also to corrosion. However, the whole magnetic embodiment may be placed inside a CNT case 702 in order to shields the system from the environment for all reasons of interference with any other metallic objects herein or around the arrangement on top of which there maybe additional micro lenses 701 for additional power generation using sun light in this case, when available.

[0045] The sensors may be programmed by software in such a way that the movement of magnetic cylinder 10 is coordinated and substantially synchronic to blade 11 to receive the maximum amount of magnetic repulsion or push to continue its angular revolution on its axis 12. Such sensitive software program systems are well known to those skilled in this art. After an initial repulsive “push,” blade 11 may continue to move in its circular movement at ever higher velocities as controlled by hardware device 704.

[0046] The system may need to be placed in a vacuum to reduce air resistance on the moving blade 11. Additionally, a recycling coolant or water radiator (not shown) may ensure low temperatures and reduce frictional heat produced by the blade circular movement and may assist in obtaining higher speeds and efficiency, while the frictional heat maybe used to heat the aircraft cabin inside the plane.

[0047] The rotary-shaft 12 may be embedded in a shielded magnetic field or connected to generate electricity for the electric jet turbine.

[0048] Now referring to exemplary FIG. 4, a two-way power generating wind turbine 109 may be used to harness the wind energy as the aircraft moves forward and the air thrust is extremely high on the blades 44. The two-way turbine 109 may include an outer case 45, turbine blades 44, and a central stator magnet 43. Either end of turbine 40 may have an aerodynamic structure form 41, 46 to allow smooth passage of wind through its blades 44 in both directions in such a way that blades 44 may rotate due to wind from either direction and thus may cause shaft 47, onto which blades 44 may be fixed, to rotate inside a stator structure 47. The turbine's blades 44 may be constructed in such a way that they may rotate and generate electricity regardless of the flow direction of the wind as the aerodynamic structure form 41, 46 depicted in FIG. 4 may alternatively be hollow to allow the smooth flow of air through the turbine 40, to reduce the weight of the turbine 40, or for other reasons. This may increase the overall efficiency of the turbines 40. Further, the turbine blades 44 may be constructed from lightweight material, for example carbon-epoxy-composite (CFRP). Turbine blades 44 may themselves be hollow or partially hollow, for example employing a honeycomb-like internal support structure constructed through the use of 3D printing or may be constructed from a solid material.

[0049] Now referring to exemplary FIG. 4A, this figure shows a design of the five blade propeller for a forward moving propulsion to replace the bidirectional propeller.

[0050] Now referring to exemplary FIG. 5, this figure shows a conventional electric jet turbine 108 with at least one thousand HP or 745699.872 watts (1 hp(I)=745.699872 W) so that the assembly of a power generator on board of this aircraft can easily generate. It is understood that a 300 HP jet engine would lift a small aircraft, however the weight of an electric jet turbine has almost one half the weight of a conventional internal combustion engine (see RR new jet turbine that weighs one tone and has a 300 HP only: https://www.rolls-royce.com/products-and-services/civil-aerospace/helicopters/rr300.aspx#section-technology)

[0051] Now referring to exemplary FIG. 6, this figure shows the flap of the aircraft wing 111 that has the same “W” 115 shaped “hinge” substitute following the concept of “all in one piece, no separate parts” in order to minimize wear tears and maintenance services at the same time this is made of the same material of DE generator DEG as now the material may be used as an actuator and not in the generator mode, i.e., the actuator would expand and move the flap upwards by applying this time electric current and thus the flap would rise up and do the same function as with an electric piston as it is used in conventional aircraft. Further, FIG. 6 shows a tendon-like piston where 140 is a supporting disk on the wing of the aircraft, 141 is a moving part of the tendon-like structure, 142 is the framing structure the moving part 141, 143 is a hinge-like element for moving a flap up and down and other support base 144 can be used with respect to the moving element 141/piston that enables the aircraft to stop during braking (in a wide open position) and is close during take off and flight.

[0052] Referring now to FIG. 6A, this figure shows the same one flap integrated in the actual wing of the aircraft plane of which there maybe another two or three flaps with similar actuators connected to the electric power on the plane.

[0053] Now referring to FIG. 7, a flap 600 of the aircraft tail is provided, which may be in a horizontally flat position from the surface of the tail to guarantee the minimum impact of the thrusting force of the air during flight. Flap 600 may then vibrate or oscillate, generating additional power to the aircraft. At the center of the tail 600 there may be a depression-like structure 120 in which a multilayer dielectric elastomer cushions 118 and 119 are firmly and permanently glued (see for example a super sea mussels inspired glue). There is a strong carbon-reinforced plate 117 placed at the base of the cushion 118 to guarantee solid and stable compression on the elastic DE cushions 118 and 119. Further, part of the above piston plate 117 allows the piston 116 to move in an oscillation-type movement, absorbing wave forces and conducting it to the other DE cushion. There may be a “W” like form structure 115 allowing the tail 600 free movement with any separate parts like a fringe following the earlier concept of “all in one piece, no separate parts” principle. This structure is made of a carbon reinforce material just like the tail 600. There may be a separation disk made of carbon fibers reinforced material with a specific straight part 128 hand wrist tendon-like material at the upper end allowing the rod to move freely without any fringe as explained above in a hand wrist like (all in one piece) allowing the shaft with two electric dynamos 129 at each end free a rotational movement in order to generate additional electric power providing the necessary energy for the functioning of the aircraft as a whole. Finally, a fixed wall 124 may connect to the main structure of the aircraft. The whole power generation system of the flap 600 may be placed in a hermetically sealed and waterproof outer case 125. Additionally, and in furtherance to the above, flap 600 may include four separate flaps and the four separate flaps may oscillate at low amplitude, while also in phase and synchronous to each other, which may further contribute to power generation in the aircraft.

[0054] The whole system may be controlled and wired by an overall electronic central unit 704 which also controls other components of this device.

[0055] Further, it may be appreciated that various technical specification that may be utilized in the above-described embodiments may be as follows.

[0056] Viscosity is the quantity that describes a fluid's resistance to flow.

[0057] For example viscosity of water at 25° C. is 8.94×10.sup.−4 (Pa.Math.s) and Air at 27° C. is 18.6 (μPa.Math.s)

[0058] The viscosity of air depends mostly on the temperature. At 15° C., the viscosity of air is 1.81×10.sup.−5 kg/(m.Math.s), 18.1 μPa.Math.s or 1.81×10.sup.−5 Pa.Math.s. The kinematic viscosity at 15° C. is 1.48×10.sup.−5 m.sup.2/s or 14.8 cSt. At 25° C., the viscosity is 18.6 μPa.Math.s and the kinematic viscosity 15.7 cSt.

[0059] A widely used formula for the calculation of viscosity of gases is the Sutherland Equation given by

[00001]$\begin{array}{cc}\mu =\frac{{\mathrm{bT}}^{3/2}}{T+S}& \left(\mathrm{Formula}1\right)\end{array}$

where b and S are constants and T is temperature expressed in Eq. 1. For air

[00002]$b=1.458\times {10}^{-5}\frac{\mathrm{kg}}{m.Math.K^{1/2}}\mathrm{and}S=110.4K.$

Power Law is another approximation to calculate viscosity and is given by

[00003]$\begin{array}{cc}\frac{\mu }{{\mu }_0}={\left(\frac{T}{T_0}\right)}^{0.7}& \left(\mathrm{Formula}1.1\right)\end{array}$

where μ.sub.0 is the value of viscosity at a reference temperature T.sub.0, which could be 273K. empirically the viscosity of liquids is

[00004]$\begin{array}{cc}\ln \frac{\mu }{{\mu }_0}=a+b\left(\frac{T_0}{T}\right)+{c\left(\frac{T_0}{T}\right)}^2& \left(\mathrm{Formula}1.2\right)\end{array}$

[0060] For water, T.sub.0=273.16K, μ.sub.0=0.001792 kg/(m.Math.s), a=−1.94, b=−4.80 and c=6.74.

[0061] As we can see from the above equations viscosity is directly proportional to temperature and the viscosity coefficient μ. However, and according to Newton's second law of motion the shear of a fluid is directly proportional to the force applied and inversely proportional to its viscosity.

[00005]$F=m_{\mathrm{dt}}^{\mathrm{dv}}$

[0062] It should be appreciated that all of the embodiments described herein are merely exemplary and non-limiting. Other changes and variations to the embodiments that can be made by a person having ordinary skill in the art are envisioned as included with these embodiments.
