I remember that I was told once that the He-162 had problems with the wooden construction (presumably overcome in the V-tailed variant)...

I wonder how G-loads will work for the FSW He-162? Anything over 1.1 Gs causes the wings to snap off above 200 kph?

4.10:
- mission for CW-21 on the Slot map showing / teaching the radio navigation
- mission for Ju-88 with the guided bombs

What concerns me is the fact that now, half a year after release of 4.09, I have not seen a single offline mission/campaign for the new maps (mod-free, of course).
Now this is a brilliant idea! The original Il-2 patches had short campaigns for new aircraft (I-16 and Bi-1 both had five-seven mission campaigns). More single missions would be excellent to see in 4.11

The reason, why I was starting this discussion about G is here http://www.me.mtu.edu/~mavable/Book/Chap1.pdf , please look first 3 pages and Table 1.2 at page 3.This is a Mechanics of Materials section - Stress education materials.

Quote:
To my knowledge, wood, being a natural composite, is, actually, less affected by fatigue, then crystalline material such as metal.
This is not my quotation, its I was find in mechanics related forum where experts explaining how it work based on Mechanics of materials :
1. The tree along fibers behaves as a fragile material, across - as plastic
PS metal material is plastic in both directions.

2. Stability - loss the most artful kind of destruction. It occurs suddenly. The most simple example-ruler(wood) which it is compressed length ways. It resists to the last, then suddenly curved and breaks.
PS Metal ruler doesn't braking in this way.

I'd really like to see a Wöhler diagram for both wooden composite and aluminum spar of equal terminal strength...
I agree. The present time wood material (really its a composite) can be equal of metal or better like metal, but I was talking about materials what was used at WW II. Thats not identical like used at present time. The plane is a very complicated mechanics device and flaying is a very stressfully action. So many forces with different strength was work on plane in flight. And if our plane caring bombs and drop its in diving, stress forces increased.

When the designer sits down to build his aeroplane he does so to a specification. Part of that specification will include the structural strength (ultimate load), the design life and the planned Fatigue spectrum. In that Fatigue spectrum are things like the expected flight hours the expected number of take off and landings and the expected number of cycles of xx applications of various G. With all that defined he then makes his aeroplane to be able to meet that Fatigue spectrum. This then means the aeroplane will LAST that long provided the fatigue spectrum is accurate.

DT are not dealing with fatigue management and aircraft life. We are dealing with structural strength solely on a mission to mission basis. Pilots are given a recommended set of limits to fly to. Stay inside the limits no drama will occur. Exceed the limits and bending things may occur, grossly exceed the limits and structural failure may occur.

" ....And if our plane caring bombs and drop its in diving, stress forces increased" .... agreed and exactly that happens in the DT G Limit module.

I imagine wood composites have a higher range of elastic deformation (flexes but returns to original shape), but worse plastic (permanent) deformation and worse ultimate strength (the point where 'necking' starts to occur, leading quickly to a snapped off wing). Metals should probably survive being permanently deformed by stress better, due to crystalization of the material with deformation (hardened metals exploit this behaviour). http://en.wikipedia.org/wiki/Work_hardening

Ultimately I don't think there will be much of a practical difference even if the two are treated the same in the upcoming patch, because I am sure the numbers/formula/ratios etc will just be set differently, based on the official numbers. Maybe wood structures will have a bigger or smaller difference between safe loading limit and max limit to take care of that

All in all, I hope that we are NOT told anything more than what the pilots back then would have access to - just 'don't exceed this G and absolutely not this G'. The exact values being hidden to us

That is the intent. Given that in a PC environment you have no physical "G cueing" we do need to provide something that will give you some idea of where you are ... you wont get precise g knowledge however..... but you will know when you have bent the jet

I asked this question on 3/8/10 and still no reply or answer. Can someone take time and answer this question. Or is this just for the good old boys country club to get answers. Seems every one here is just advoiding answer questions excpet for their friends!!!!!!
Thank You

Maybe it's just a case that no one wan't to answer if they don't know the answer to the question. In a team situation you may not know what other people are working on.

Has TD released any 3 or 4 engined bombers? If not you many need to go to the mod sites that released them and ask the question.

I recall that this was already answered earlier. Up to four engines is supported, although I guess not many people have four throttles.

~S~
Sorry if I sounded off like that, give to old age and medical problems I have. I will not go into that because I am not sure how much longer I will be around.
Any way Thank You for your answer. I did read every post and replies here, but may have missed the answer.
So TD muti-throttle ect... will support up to four engines. I am glad because I am getting a new Flight Yoke and Throttle set up, since I only fly the USAAF Heavy Bombers. So in another word I can get the set up I want and use at least two throttle set up.

Again sorry for the I sounded off. Thank You TD for your work.
