[0049] Technical Specifications

[0050] This disclosure describes a system that uses Faraday's law to rapidly and directly convert the kinetic energy of a magnetized and / or conductive projectile (propelled by chemical energy) into usable electrical energy. In one example, the magnetic braking action of a "reverse coil gun" removes energy from a high-kinetic-energy projectile (whose initial kinetic energy is generated by chemical energy) and generates a voltage in a circuit magnetically coupled to the projectile. The voltage-dependent electrical energy can be used directly by the application or to charge a capacitor or battery for later use. This system significantly reduces the weight of the energy storage.

[0051] Firearms Examples

[0052] Figure 1 A regenerative braking system 100 is shown, comprising a barrel 102 having a bore 104, a circuit 106 including a plurality of conductive components 108 distributed along a length 110 of the bore 104, and a projectile 112 including at least one material 114 selected from conductive or magnetic materials of the magnetically coupled conductive components 108 as the projectile 112 moves along the length 110 of the bore 104. Examples of conductive components 108 include, but are not limited to, coils 144 or coupling coils (144b) coupled to magnets 147. Examples of magnetic materials include, but are not limited to, permanent magnets 145.

[0053] When the projectile 112 moves along the length 110 of the bore 104, causing a magnetic interaction 120 between the conductive component 108 and the material 114, the circuit 106 stores energy 116 generated by the current 118 induced in the conductive component 108. The magnetic interaction 120 also causes braking or slowing of the projectile 112. In one or more instances, the circuit 106 includes (or is connected to) a capacitor 154 and / or a battery 156 for storing the energy 116 to power an electrical appliance or other device 158.

[0054] exist Figure 1 In the example shown, the system is an accessory that is removably attached to or remounted on the firearm 130. Connector 132 is used to attach barrel 102 to the muzzle 134 of the firearm 130, such that a projectile 112 (bullet 136) is fired from the muzzle 134 into barrel 102. Barrel 102 or connector 132 includes a vent 138 located in front of conductive component 108, such that vent 138 exhausts exhaust gas 140 from the firearm 130.

[0055] Piston example

[0056] Figure 2 An example regenerative braking system 200 is shown, wherein the projectile 112 includes a piston 202. The system further includes a reactor 204 (e.g., a combustion chamber 203) connected to a barrel 102, and the reactor 204 is configured to (1) react a chemical propellant 206 with a reactant 208 (e.g., air or oxygen) to form an exhaust product 210, and (2) guide the exhaust product 210 to propel the piston 202 through a bore 104. The reactor 204 includes an air inlet 212 for inputting air, an outlet 214 for outputting the exhaust product 210, and a spark plug 216 for igniting the chemical propellant 206. The regenerative braking system 200 further includes a mechanism 218 for returning the piston 202 to the reactor 204 after propulsion and braking, after the piston 202 has traveled along the length 110 of the bore 104. In the example shown, mechanism 218 includes connecting rod 220, crank 222, crank pin 224 and crankshaft 226, wherein a portion of the reciprocating motion of piston 202 is converted into rotational motion of crank 222, which is then used to drive connecting rod 220, which drives piston back to reactor 204.

[0057] Example Magnetic Field Distribution

[0058] Figure 3Various examples of magnetic interactions 120 between the conductive component 108 and the projectile 112 are illustrated. In one embodiment, as the projectile 112 moves along the length 110 of the bore 104, the projectile 112 generates a first magnetic field 122, which is configured to induce a current 118 in the conductive component 108. The current 118 generates a second magnetic field 124, and the conductive component 108 is configured such that the magnetic interaction 120 between the second magnetic field 124 and the first magnetic field 122 causes the projectile 112 to brake, for example, by converting the kinetic energy 117 of the projectile 112 into electrical energy 116. In various examples, the second magnetic field 124 does not extend behind the projectile 112 to prevent pushing the projectile 112 along the bore 104.

[0059] In another embodiment, the projectile 112 comprises a conductive material, and magnetic interactions 120 induce eddy currents in the conductive material of the projectile 112 as it moves along the length 110 of the bore 104. The formation of eddy currents causes braking of the projectile because the kinetic energy 117 of the projectile is dissipated in the eddy currents.

[0060] Application Examples

[0061] Figure 4 A person 400 (e.g., soldier 402 or hiker 404) is shown operating a regenerative braking system 100 including a handheld or portable device. The handheld device is used to charge the battery for small-scale power generation in the field. In one or more embodiments, the conductive component 108 is configured such that braking causes the projectile 112 to exit the bore at a speed of less than 10 m / s, a speed that can be stopped by an unprotected hand or a protected hand (e.g., a hand protected by armor or gloves). In one or more further embodiments, the kinetic energy of the projectile is reduced by at least 90%-99%, and at least a portion of the kinetic energy is converted into energy 116, including electrical energy. The average energy in a moving .50 caliber rifle cartridge is approximately 50 kJ, which is sufficient to charge an alkaline AA battery (approximately 10 kJ energy storage capacity), a C battery (approximately 35 kJ energy storage capacity), and a NiCd battery (approximately 1 / 3 of these energies) or a NiMH battery (approximately 1 / 2 of these energies). Alkaline D batteries (approximately 75 kJ energy storage capacity) can be charged using multiple-fire or larger caliber cartridges.

[0062] In one or more instances, energy 116 is capable of supplying power to at least one electrical appliance or device 158 selected from cellular phones, radios, televisions, computers, GPS systems, air conditioning systems, or electric vehicle motors (electric motors).

[0063] Figure 5 It shows including Figure 2The regenerative braking system 200 is shown in a vehicle 500 (tank). The vehicle further includes an electromagnetic weapon 502, and the regenerative braking system 200 is used to rapidly charge the energy system of the electromagnetic weapon 502. Although a tank is shown, in other instances, the regenerative braking system 200 is mounted on nearby aircraft and ships (e.g., boats) to rapidly charge naval or aircraft guns, respectively. The energy of a firing M1 Abrams tank hull is approximately 30 MJ, sufficient to charge multiple batteries or hybrid vehicle batteries (approximately 5.4 MJ of storage capacity). Other examples of vehicles include, but are not limited to, cars, trucks, jeeps, or buses.

In one or more instances, the barrel and bore are manufactured using materials commonly used in the manufacture of firearms (e.g., metals).

Examples of materials for the magnets include, but are not limited to, rare earth materials (e.g., neodymium).

[0071] Box 604 indicates obtaining or manufacturing a projectile 112 comprising at least one material 114 selected from conductive or magnetic materials that can magnetically couple conductive components as the projectile moves along the length of the bore. Examples of magnetic materials include permanent magnets, including, for example, rare-earth materials (e.g., neodymium). Examples of conductive materials include materials commonly used in the manufacture of conductive coils, windings, loops, or wires, such as metals, including but not limited to silver, copper, tungsten, etc.

[0072] Box 606 represents a circuit including a conductive component. Circuit 106 is configured to store energy 116 generated by a current 118 induced in the conductive component when a projectile moving along the length of the bore causes a magnetic interaction 120 between the conductive component and the material. In one or more instances, circuit 106 includes (or is connected to) a capacitor 154 and / or a battery 156 for storing the energy 116.

[0073] In one or more instances, circuit 106 includes a buffer circuit:

[0074] The capacitor 154 is charged using current 118 and with a first time constant corresponding to the time scale of the projectile 112 traveling along the bore 104; and

[0075] According to the manufacturer's instructions for the battery, capacitor 154 is discharged into battery 156 with a second time constant that is longer than the first time constant and corresponds to the charging time.

[0076] Box 608 represents the final result, such as Figure 1 or Figure 2 The regenerative braking system shown.

Furthermore, batteries lose energy slowly and require frequent recharging, necessitating a power source and energy supply for recharging. The method described herein requires transporting only one battery in the field, as the energy is stored in the chemical energy of the propellant used for projectile firing, and this chemical energy is only converted into battery energy when recharging is needed.
