Should jets explode?

Well, the upper wing surfaces of many Yak-9s weren't supposed to peel off in flight. They should stay tightly glued to the wing structure like crazy, not peel off. But they did peel off. The obvious culprit would be the quality of the glue bonding the wing skin to the structure. Turned out that the camouflage paint on the wings contained an unauthorized substitute ingredient that interacted negatively with the glue, which BTW was applied correctly. In the meantime, the wing structure was redesigned and strengthened. The point is that just because something shouldn't happen in a design doesn't mean that it won't, and the cause isn't always the most obvious one.

You started this "debate", and I'm caring to post my opinion, so don't go flaming me for taking up your invitation.

Maybe Fearfactor didn't give this topic a good start.

But he has a point. On FB release, I didn't cared much about it.
Still, right now after a lot of more reading on the subject, I know it is somewhat exaggerated.

Jumos B engines, being a cheaper version of the Jumo A, got this problem. But on those engines if you pull back the throttle, the engine will flame out.
So, some fire may start, but it will start in a non enclosed area. Also the fuel tank is on the fuselage, and not in the wings. Maybe Luno got a point there, but anyway...

More... there are really not that many reports on this happening when it entered regular employment. Actually I can't find any! It did happened during evaluation, but that wasn't a hazard on normal operations. On the next Jumo, this problem was corrected.

Now, forget the fire at take-off. (That's what I was talking about before)

You fire some bullets at a Me262 engine, and it will always take fire... even if you throttle it out... so, all hits are on the tiny valve? When this happens, I agree with the pilot that bailed out. But the valve is really a small target... why did all the times that this engines are hit, they just got in flames, and they can't be stopped with a dive and fuel cut out?

This really don't connect with operation reports.

Actually, my post was directed at you. However, since you didn't post the comment that I responded to, then my post is irrelevant. Sorry.... Though on it's own, the technical point I made in the first part still stands.

(Sorry 'bout that, fearfactor.)

I acknowledged this, and understood the confusion. Sorry myself for flaming you.

Yes, it still stands... on the Yaks!

Me 262 has to have some "balancing" damage modelling.

A few MG pings in an engine and your done, its ablaze no matter how much you "dive it out", it reminds me of the FW190 wing damage, few MG hits and its time to head home mission over.

Bf110 has a explosion/flame retardant cockpit you can sit in it all day long surviving with fuel tanks exploding [last count was 45 fuel tanks exploding] also de-winged,
so some strange damage modelling has been around a long time, some has been introduced with the new patches like the bf110 endless exploding fuel tanks.

Would be nice to clean the bugs up but its a thankless task for them at times I imagine.

If it makes no sense and has never been fixed its not a bug its balancing

PS: check the Me262 climb rates also

Actually, there is some reversal on TD work getting more attention.

And more... its happening that there is some place for reasonable discussion here, so why not consider some very old points into mature discussion.

TD work is appreciated, and if they are not putting more things out, I'am sure it is from lack of resources and not from lack of goodwill.

Starting a topic about a weird subject, and keeping it clean, is actually signs of good health.
