The Late Yer-2’s the Ach’s specifically have diesel engines and diesel fuel which specifically in the L variant I have not played the E the fuel bursts into flames from either 1 or 2 50. cal munition that usually is AP-T and no HEF-T on Wikipedia, airpages.ru and many more small sites that you rarely see and they all say the ACH-30B engine type was a Diesel powerplant which would naturally mean it should be harder to ignite but it isn’t for some reason.
do you know how hot incendiary rounds are?
Rule of thumb, it’s never “1 or 2 .50 munition.”
M2 brownings have insane fire rate and usually there’s 6 or 8 shooting at the same time.
And if the pilot set up their convergence right and is shooting at ideal range, most of those 6 or 8 guns are gonna hit at once.
Within a few seconds of trigger time, you’re sending hundreds of bullets down range.
okay it is my mistake I didn’t read down on diesel enough, Diesel fuel burn Smolderingly so let’s say I am wrong about resistance to heat still diesel would yes burn but more like a contained fire since diesel burns so calmly it would struggle when leaking on the wing to keep ignition if it isn’t say bursting out a huge flame like gas and would most likely stop burning the wing key word most likely since it can be possible it doesn’t if it were to ignite on the fuel tanks in the back of the engines.
Diesel burns very well - it is a bit harder to ignite because it is not as volatile as petrols ie it normally gives off less vapour at any given temperature,
But I imagine that at high speed there is enough airflow and pressure differences for it to atomize through leaks pretty well - and that will burn just fine.
