Centrifugal guns?

With the introduction of modern brushless motors, could we build a man portable centrifugal gun that is reliably into the human lethal energy range?
Of course it doesn't approach the abilities of, say, a rifle, but as a proof of concept?

    Air compressor bb guns are neat, but that's about where it ends. You're adding needless complexity to something that has been solved by gunpowder and less mechanically complex weapons.

      I know, just for fun.

      There's proposals to build a rocket launching system that uses spinning.

      I saw that. Spinlaunch or some such.

      This works around legal obstacles, not technical ones.

      The feasibility depends on releasing the projectile accurately. For the mechanical precision of a given release mechanism, and timing and accuracy of a given rotational position sensor, you could calculate the max RPM that an Arduino could time the release with the required precision, and come up with a wheel size that would give you the desired amount of energy.

        Wouldn't you need some massive gyroscope mount for this thing to aim?

        Rather than relying on precise release timing, wouldn't it be better to have a flywheel spin up then engage a centrifugal clutch attached to a linear catapult?

    Yes, that would be possible. Now making it accurate enough to actually be aimed is a whole different ballgame.

      I don't see why you couldn't centrifugally fling a bullet into a rifled barrel but then again my IQ is 83

        That would be very silly, since without the constant pressure of burning powder (or compressed gas) behind the projectile the barrel would only serve to slow down the bullet tremendously via friction.

          Maybe you could leave the barrel with a tolerance big enough just to stabilize the round without slowing down massively since you don’t need a gas seal and you could get shotgun slug precision

            You're spending all that money on launching a huge shell at something. You sort of want to be precise if it's a sabot and less costly than a pgm.

              Spending all that money?

              What?

              Get a hardware pipe and size the round accordingly to be a bit smaller and make it round, same presicion as ball slug from smooth bore shotgun.

              Easy peasy

                >man portable
                No, not in a million years, best way to think about this idea is some form of arty.

    Yes. Centrifugal guns date back to the American Civil War. They re-entered the popular imagination in the mid 2000s with the DREAD pintle-mounted concept.

    However, besides the gyroscopic issues the muzzle velocity on it was subsonic without a megawatt level power supply, so while lethal it wasn't militarily viable.

    Considering that slings can kill...

    Realistically how fast can you spin up a 12 inch wonder material flywheel before it explodes?
    I could see some sort of non chemical explosive flywheel mine on a waist level tripod. Just get a horizontal hardened steel wheel with 100s of scorelines for it to fail at and have it rapidly do so when triggered.

      For what purpose?
      Any electric/ICE/etc. power source that can spin a flywheel up anything close to fast enough is gonna be much, much larger than an explosive charge delivering the same frag energy.

    https://en.wikipedia.org/wiki/SpinLaunch

    SpinLaunch is marketing their centrifugal tech for space launches:

    >SpinLaunch is developing a kinetic energy space launch system that reduces dependency on traditional chemical rockets, with the goal of significantly lowering the cost of access to space while increasing the frequency of launch.
    >The technology uses a vacuum-sealed centrifuge to spin a rocket and then hurl it to space at up to 5,000 miles per hour (8,000 km/h). The rocket then ignites its engines at an altitude of roughly 200,000 ft (61,000 m) to reach orbital speed of 17,500 miles per hour (28,200 km/h). Peak acceleration would be approximately 10,000 g.[10]
    >If successful, the acceleration concept is projected to lower the cost of launches and to use much less power, with the price of a single space launch reduced by a factor of 20 to under US$500,000

      kek. those retards are wasting tax money on this shit.. why not to fucking shoot the shit up like Jule Vernes scifi?
