What happens if a bullet runs into the turbine?

[FlyingCoffin]

so we have a 50cal bullet from a f-86 which is luckily happy to fly into the turbine of the mig15bis. does the bullet melts away and a fluid of hot iron hits the motor? and so the damage is done with a fluid or is the bullet still intact and hard?

 

so which material is the bullet of the f-86 made off?

and which temperature does the exhaust have of the mig15bis? does it even reach 3000f?

In DCS? It hits whatever hitbox comes first and reduces the hitpoints of that hitbox by a certain amount.

In real life? From the front, it would hit the compressor blades, damaging them, causing more fragments to do unhealthy stuff to the engine. From the back, it would hit the turbine blades, causing imbalance and probably a tiny loss of efficiency but I guess it wouldn't enter much more due to the exhaust.

And btw, it's 12.7, not 7.62.

does the bullet still stay in bullet shape or does it become fluid? the jet which gets hit is close to mach 1

1. What speed the target jet flies is irrelevant, because you both fly together and thus - relative speed between you and your target matters more. Not much more, however. It's going to be within 50 m/s, which is negligible compared to bullets speed of 800+ m/s at impact.

2. Because of point 1 above, bullets fly through target's exhaust for a fraction of a second, which is not enough to even warm them up much, let alone cause any melting...

3. ... which would never happen anyway. Engine exhaust temperature is shown on relevant instrument in every jet plane. For MiG-15 it's typical for all no afterburner engines of the era, which is between 500 and 600 C (900-1100 F) in cruise, closer to 700 C when at full thrust. Meanwhile, .50 API/APIT machine gun bullets had typical construction for any bullets, which is mostly copper and brass alloy jacket with steel core (plus a tiny little bit of other incendiary and tracer stuff). All these materials have melting points in the range of 900-1500 C (1600-2700 F), so they couldn't melt even if kept in jet blast longer.
