And reinforce it to the point it isn’t simple sheet metal any more.
HEF is meant to damage the fuel tanks not wings spars.
It was bad for anti infantry for other reasons but made for a decent anti vehicle weapon.
Then why not use a single gun with more ammo to increase spray time? They needed multiple guns to ensure multiple rounds impact at once. Why do you think the Me262 had 4x30mm?
AFAIK velocity difference is accounted for. But this was at long range so the bullet is slowed down considerably and when a round penetrates it doesn’t transfer all its KE into the object it hits.
That makes it even worse. With APDS it would be a <20mm hole in the wings that makes the whole thing fly off.
Yes but thickness of each bend and and flange is around 2mm of Aluminum (assuming they use the same sheet metal for the reinforcements) which is not exactly strong. Even if the HEF doesn’t completely destroy the spar, it would cause heavy damage and the weight of the wing + engine could be enough to rip the wing off.
Meant for fuel tanks does not mean it only damages fuel tanks so I’m not sure what your point is here.
It’s an offensive grenade, meant for reducing friendly fire by limiting fragmentation and its role is mainly to disorientate the enemy.
Well take into account that you were also heading into the direction of the SPAA so that’s added relative velocity. And yes KE transfer is not perfect but this means that at the very least there will be lots of holes and not many fragments that were stopped.
Once again, my point stands, you can keep quoting and responding to each part, as you tear it apart trying to argue something completely different however, I still stand on my point, It does not change anything and If you have been able to read, the Ki-49 was being used as an example of a very survivable aircraft in the game at this point that survives way more than it should depending on the model you use.
Not all spars are weak at every point.
For example. this is a section of a spitfire wing spar.
At the root it’s solid. Further out it becomes thinner and more box section. Hitting there with a 20mm would weaken it but closer in I don’t see it penetrating or doing shit with with HE. I’ve shot alu before with various types of guns and calibers. It is used as armor on some vehicles for a reason.
Low tier bombers being more survival has nothing to with this thread. They survive a lot of punishment being the guns they fave are shit and deal no damage.
Will look for it later.
Must have been a newly trained pilot why didn’t he just shoot the wing center mass once to remove it?
The point still stands, and the fact you continue to reply to everyone isn’t helping your case. Also correction, I meant the Ki-67, I mistake them sometimes. The Ki-67s are around the early mid-tier. Aka they are facing cannons.
I don’t. I think you overestimate Aluminum’s effectiveness against projectiles.
What armour? Aluminum is 0.3-0.5 the effectiveness of RHA depending on the alloy. So 2mm of Aluminum is like 0.6-1mm RHA. And from the HEF statcard, it can penetrate 3mm from the HE impact alone not accounting inertia and plane speed.
Again this all assumes the SPAA got an extremely lucky shot and hit your spar directly.
Its still a significant amount of speed, thats an additional 10% velocity from 1100m/s muzzle velocity.
It doesn’t need to do a lot of spalling if its a direct hit. Most of the fragments will surely perforate the spar.
Something else I would like to point out is that comparing fighter and bomber spars is apples to oranges. Fighters need the extra strength of steel to handle the far higher g loads, whereas bombers would prefer aluminum spars as that is weight savings to carry more fuel or ordinance
I actually got to work a little bit on a B-29 at a museum and those spars are huge. They are well over a foot and a half tall. Awesome aircraft to work on
If the spar got penned and the round exploded behind it the fragments wouldn’t deal damage to thag same spar and there would just be a small hole.
The round was already traveling over a km and lost a lot of speed so it’s unlikely to impact at over 1100m/s even witht the speed difference accounted for.
The fragment aren’t big enough to deal serious damage to a spar even after a few rounds hit.
It would have to go through the skin first which would activate the fuze.
Uh yes. Assuming the round lost half of its speed before it hit you (550m/s) then the extra 120m/s would make an even bigger difference since it would be an extra 20% of velocity.
