new zero does 550 in dive np
« on: July 08, 2002, 12:14:03 PM »
I put this in bug reports, but I wanted to post it here too.  Anybody know what kind of stress the new zero was supposed to withstand?  I have the film, its 194kb in size, is there somewhere I can put it?  If you want it I will email it.

Pulled out at 567 only lost rudder (that was before I pulled out.  near 560), how ever that happened.  I was using the mouse for a joystick with no rudder input.  maybe combat trim did it.

true, and it is listed on the readout in the film viewer  I am going to attach a screen shot.  Just thought of that

I read somewhere, and not just once, that the NTE velocity of the A6M series was in the 410-450 range, not in the mid to upper 500's!
So that's why the standard P40 move of diving away from the Zekes has not been working.
I knew something was wrong in the land of the Rising Sun........;)

your right eddie, and it gets up there fast too.  I kept trying the diving maneuver, but it never worked no matter our original e states.  

Anybody got numbers?  Wish htc would read this.

HHmmmmm

I've never been one to outright criticize HT and Pyro's work, and I won't start here, but.......
I went looking for the books I had read on the A6M models, and the A6M5 was strengthened to increase diving speed to 450, but that was it's NTE limit.
Look's like someone possible gave the "new" Zeke too much structural integrity or something, at least from looking at what has been posted.  I mean, I've had a Jug near that speed a few times, only to lose the wings seconds later.  
Me thinks something is amiss here.............

It wasn't the structure of the A6M2 that would fail, it was the skin.  The skin would peel off as it wasn't think enough.

I think yer right Karnak, and it just adds to what I was saying......
The A6M2 should've fallen apart at the speed shown above, and it didn't.
As it is modeled now, it can outdive even a freakin P-47, maybe even a P-51.
Go figure............;)

Outdive, outroll the zero catch up within 2 sec when ur in a P40

It's frigginly frightning

I believe they will get to it as soon as they realize the problem.  Pretty large bug.  If the IJN had zeros like these, they would own the pacific by 1944.

And what exactly would you expect to happend next if the skin failed on the wing of an an all metal WW2 aircraft......

GRUNHERZ,

Thw structure would then fail, but the critical failure was not in the structure and the structure having failed does not change the situation at all.

I was pointing out that the underlying structure of the A6M was adequately robust, but needed a thicker skin.

If an investigator were to do a report on an A6M2 that crashed after diving too fast, the investigator would conclude that the aircraft's skin was at fault.  The subsequent structural failure is irrelevant as it is not the cause of the crash.  The crash would still have occured if the structure had not failed.

Clearly the A6M2's tolerances in AH need to be adjusted.  It also might roll to well.

Karnak,

The Zeke had stressed skin just like most aluminum planes in WWII.  If the skin fails it is a structural failure.  There is no separate 'underlying structure', the skin, ribs, and spars all make one structure.
