Landing gear damage model and other issues

[Witchking]

I notice that the tires blow out very easily on the flanker. If u try to taxi and turn at high speed. The aircraft is pretty stable...doesn't tip over on the side like the f-15 or frogs. Is this normal due to the center of gravity differences?

Also..

Even when the tires blow out...there is no damage model unlike the blown out tires u see on the su-25/t versions. The tire just dips into the ground and that's it. Also I haven't seen proper damage to the landing gear even when I landed down hard...tired blow...I hear scraping but thats it.

 

Also I thought there are new interactive tutorials? I only see the old fc era videos.

 

Cheers

Taxing to fast will damage the tires :)

 

also the training missions are in missions not training

[Witchking]

awesome. Thanks for the info.

 

I understand about blowing out tires...but there is no damage model for the tire blowout? unlike what we see for the Su-25 or 25T...ripped or flat tire....flopping on the rim? ;)

 

All u see is the same tire model halfway sunk into the ground/clipped into the ground.

[BIGNEWY]

No problem glad I could help.

 

Bare in mind the SU-27 is currently beta and we may see tweaks made :)

[Witchking]

For sure. :) I just wanted to post it up so that it isn't missed in the tweaks for the next patch. ;) Also.... no heat haze at idle.... but I remember a post somewhere where Dima said "no environmental effects" on the engine performance in current state. So hopefully the little things/effects will be fixed/added in future.

 

Feature request BTW...for DCS 2.0, it would be nice if you can see that initial FLAME when the engine is started in the Su-27. See the following documentary at 23:04/05 . ;)

Update

 

Here is what I mean/// hard landing with Su25T: blown tires and bent landing gear. The Su27 is missing this

I cant get past the first mission of the SU27 campaign due to tires blowing out at 50kph, taxiing in a straight line...

 

How the hell to they stay inflated during a 250-300km/h landing??

That sounds really odd. You should post a track.

[Witchking]

yup... you have to taxi at less than 20km/h. This seems hard to do as the static friction seems high enough to get the aircraft moving...but once it moves, the throttle level needs to be dialled down or the aircraft speeds up to 60 or so speed. But cut it down too much to control, the aircraft slows to a stop...repeating the process. So I end up basically tapping the wheel brake a lot bobbing the nose up and down during taxi. Tires blow at higher speeds when you even try to use the rudder/change direction at higher speeds.

Will do later tonight if I have the time.

It's logged as a bug...

what about this video?

no damage?

is su-27 landing gear strong as shown on this video?

good try! :thumbup:

[Witchking]

yup...the gear seems unusually strong...even compared to the frog and toad.

[Witchking]

I know the flanker has a lot tougher landing carriage than the dainty little F-15 landing gear...but dayumm.... the eagle's feet are so much more easily damaged and so much more delicate than the flanker. I don't know if this is an incomplete model...but its really hard to screw up or just a bit too easy to land the flanker.

Has this been fixed in 1.2.12 OB? Can anyone confirm?

 

Thanks

[Robin_Hood]

That is apparently a question of engine thrust, and the same effects happen in flight. See this thread (I hadn't heard it was acknowledged as a bug before though, we will see I guess).

[theropod]

with 1.2.12 patch,su-27 has no longer strong gear issue!

they can get damage!

thank you ed

Haha...i did a test yesterday night in 1.2.12 and let the aircraft flip, left it full throttle and ejected...it rolled, flipped and even then the gear wad strong. Lol. Unfortunately it wasn't reproducible in the track file.

[Witchking]

Also... Inspite of that, the gear damage model is no where close to what we can see on the old FC level su-25 and su-25t. On those, the independent great suspension has a graphical damage model and the tire can also can stripped.

It is not just a thrust issue. Tires should not be blowing up when breaking at 30km/h. Or should they? Is this how it behaves in RL?

[Witchking]

They shouldn't blow or strip at 30km/h

 

but they should under more tough conditions

 

 

[Witchking]

What do u know...the tires do burst on the flanker too... trying to skid at a relatively high speed. :p

 

 

[Nedum]

Have you ever managed that the right wheel get some damaged?

Only the left tire/structure get some damage.:unsure:

I was only referring to this part

 

...but once it moves, the throttle level needs to be dialled down or the aircraft speeds up to 60 or so speed. But cut it down too much to control, the aircraft slows to a stop...repeating the process. So I end up basically tapping the wheel brake a lot bobbing the nose up and down during taxi.

...not the blown tires problem. I do not have an opinion on that one, as I personally blow tires very rarely. I do not use brakes for keeping my speed during taxiing though, instead pumping the throttle like crazy. Doesn't make for a very clean taxi, mind you, but maybe it will have less of a tendency to blow tires.

 

Anyway, great to see the damaged tires effects added in the new patch :)
