Base Bleeds and Bullet Engines

What size bullet are we talking here?

>>33923959
Most likely large, artillery grade ones. If it could be sufficiently miniaturized it would be interesting to see assault-rifle sized or so ammunition with scramjets in them just to see how fast they could get to see if they could serve as low-power kinetic penetrators or something.

It can go as fast so long as the bullet head doesn't exceed 7,600 degrees, the melting point for most forms of depleted Uranium. Though the army could just use literal rocks/ceramics as bullets too.

I doubt they could survive the acceleration though.

I want a Gauss Gun firing these.

it just needs to stay in one piece, especially if it is ball-shaped so it's specific orientation doesn't matter as much

superheated balls flying through things sounds like fun, because even after impact it would continue to be hot (imagine a bullet melting through a solider or a tank into a crew member's lap)

Only real application I can see for this would be anti-material rifles, sort of how the first Barrets were marketed. "It's too big for people, but you can render enemy equipment inoperable from a mile away.

System cost and cost per round are going to be pretty insane, but it seems like it'd be a natural pairing for that CIA project that made a .50BMG round target-seeking. Depending on velocities and penetration capabilities, this might also be a viable Anti-Tank system, at the very least it seems like it'd be a cheaper alternative to countering heavy cover and armored vehicles than an AT-4 or Javelin without the limitations of the 203.

By the time you're putting an engine in the projectile, we're no longer talking about bullets.

Arty, though...

>scramjet in a bullet
Are you retarded? Building a fueled, precision manufactured engine into a bullet that gets fired off by the dozen and immediately destroyed?

Even putting aside the practicality aspect, no.
You couldn't even get airflow into bullet at so small an intake, so it physically cannot work. Air doesn't scale down when you scale down your engine. Also how do you hold fuel and do fuel injection?

ha, good one.
