What are the advantages of a coilgun v.s. a railgun?
2019年11月14日 · A railgun is an electrically powered electromagnetic projectile launcher based on similar principles to the homopolar motor. A railgun comprises a pair of parallel conducting rails, along which a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other ...
Best material and shape for small-arms railgun/coilgun amunition?
A railgun round is a kinetic impactor and you want to maximize energy delivered by your kinetic impactor. Considering first a railgun projectile in the atmosphere: Maximize mass. In the atmosphere, the air hits the projectile as fast as the projectile hits the air, and as v increases losses of kinetic energy to air resistance also increase.
What's more viable as futuristic infantry weapons, rail/coilguns or ...
2016年10月5日 · Railgun, anti-infantry/light armor weapon, standard ground combat If there is a special weapons company/platoon, such as modern militaries have, which handle mortars, explosives, and machine guns - then such a weapons section may be better suited to handling the special purpose weapons while the infantry riflemen carry reliable chemical ...
science based - Handling recoil of hand-held railguns
2017年5月22日 · A typical 7.62x51mm rifle load fires a 10g projectile at a velocity of 833m/s, and represents a practical upper limit for rifle recoil. Scale down the projectile size to 2.5g, and the velocity up to 3,332m/s, and the momentum remains the same while the muzzle energy increases by a factor of four.
What is a realistic maximum velocity of a coilgun round from a …
2021年2月28日 · "Using a massive electrical pulse rather than a chemical propellant, the railgun can launch projectiles much farther than the 13-nautical-mile range of the US Navy's standard 5-inch naval gun," the US Office of Naval Research says. That …
When are Turreted Railgun better than Spinally-Mounted Railguns?
2022年5月12日 · $\begingroup$ @AlexP: A guided missile can be defeated by many means: counter missile, antimissile railgun fire (which would fill the same roll as AA fire and rockets fill in modern sea-ship defenses), hacking/jamming, etc. Rail gun rounds are faster (and potentially do more damage), are harder to "see" and defend against, and are much cheaper (at the moment, by two factors of magnitude ...
How much energy I would require for a railgun to shot a bullet in …
2021年4月9日 · A 'normal' rifle bullet (Winchester .308 firing and 11 gram bullet) imparts some 3551Joule to the bullet. One energy calculation later: Your railgun requires 3551/0.47 = 7555 Joule total energy per bullet. Slightly more than half of this ends up as waste heat in the device.
technology - How effective would a mini rail gun be?
Since the physics of the railgun make a "muzzle break" device impossible (there are no expanding gasses that can be redirected backwards), even though raw energy of the bullet is a bit higher in the .50 BMG rifle it's very probable that your shooter will feel more recoil with your railgun than with a .50 BMG rifle.
How feasible are my Gauss weapons? - Worldbuilding Stack …
2023年3月8日 · Let's shape the railgun to be roughly the same form factor as a M4. .. let d be the width of the M855A1 round, or 5.56mm .. let r be the width of the M855A1 round, divided by approx. e+1, or 1.495315mm (0.0014953143028) there are arguments for thicker or thinner rails, and measurements that make sense, but honestly I chose this value to make ...
Engineering considerations for a hand-held railgun carbine
2023年2月8日 · And after about 2 months of engineering and lots of sore shoulders later, created the K-10 Railgun Rifle. The K-10 'Kitsunebi' Carbine is the first man-portable variant of the R-10, making it a rather unique all-purpose light assault weapon, with high anti-material performance.
