Inertial Accumulator (IA) for onboard power supply of spinning and non-spinning projectiles and Directed Energy Projectiles

Abstract

The Inertial Accumulators, which transform G-forces and/or rotational energy of a projectile into rotational energy of flywheel, store it and convert into electrical one to feed onboard electronics and/or high-energy emitter of Directed Energy Projectiles.

1 . An Inertia Accumulator (IA) for spinning projectiles that comprises:
 a. a free-rotating flywheel having a shaft and bearings in which said shaft can freely rotates, wherein flywheel axis is aligned with rotation axis of said projectile;   b. a separate electrical generator firmly fastened on inner surface of shell of said projectile, which has a shaft mechanically connected to said shaft of said flywheel,   
       wherein, when said projectile is fired, it start spinning, whereas said flywheel stills not spinning yet because of flywheel mechanical inertia; thus, said flywheel starts spinning about shell of said projectile, said flywheel starts rotating said shaft of said electrical generator so transforming rotational energy of said flywheel into electrical one. 
     
     
         2 . The Inertia Accumulator (IA) for spinning projectiles of  claim 1 , wherein the free-rotating flywheel of  claim 1  contains a set of permanent magnets on its rim, and the spinning projectile of  claim 1  additionally comprises a firmly fastened on inner surface of the projectile's shell stator coil encircling said flywheel; thus, the separate electrical generator of  claim 1  is eliminated and said Inertia Accumulator works as an electrical generator. 
     
     
         3 . The Inertia Accumulator (IA) for spinning projectiles of  claim 1  feeding a pulse generator of Directed Energy Projectiles, which comprises spinning shell and free-rotating core that have equal inertia moments, wherein an array of permanent magnets is mounted on inner surface of shell of said projectile, and a rotor coil is mounted on outer surface of said projectile core, which contains a payload; thus, it allows maximally utilizing rotational energy of the projectile. 
     
     
         4 . An Inertia Accumulator (IA) for a non-spinning projectile comprising:
 a flywheel, which is a rotor of an electrical generator, that contains a set of permanent magnets mounted on rim of said flywheel, wherein said flywheel has threaded sleeve,   a hollow shaft, which axis is aligned with axis of said projectile, having a thread on outer cylindrical surface; said shaft is mounted on a base that is firmly attached to shell of said projectile, wherein said flywheel rests atop of said shaft and thread of said shaft is engaged to thread of said sleeve that allows said flywheel start rotating when it is sliding along said shaft under G-forces,   a thin pin preventing said flywheel from accidental moving,   a bearing enclosing said shaft on another end,   a coil of stator of said electrical generator mounted on said base,   a rectifier circuit and electrical stabilizer mounted as an electrical unit that is placed inside said hollow shaft;   
       wherein, when said non-rotating projectile is fired, said flywheel is exposed to G-forces; so, said flywheel shears said pin and starts moving along said shaft and rotating; and when said flywheel reaches end of said shaft, it disengages from thread of said shaft and becomes tightly fitted on said bearing allowing said flywheel continue rotating; therefore, said flywheel together with said stator starts working as an electrical generator so generating electricity.
