Weight on landing gear

[[APAF]VR_Spartan85]

Just a little curiosity,

I was looking at my bf110 in the main menu with an assortment of heavy and light bomb load and was wondering if difference in weight is shown in the landing gear?

 

With full tanks and heavy load are the oleo's compressed more than as if there was zero fuel and empty armament?

 

I'd suppose the aircraft would sit higher on landing after a mission?

 

Also, is hydraulics leaks/damage modeled in game?

 

If you hit a line, with the gear drop?

Back ups and hydraulic fuses per say?

Brakes fail?

 

OK now I'm going to far...

In my opinion, the weight of bombloads is not modelled very well. Aircrafts are to agile with heavy weights. And I suppose it will be the same with the landing gear.

And as you speak about the brakes of the Bf110, you don't really need them anyway. Land without braking and your 110 will stand after the same lenght of the runway, as when you brake.

You can Definatley Notice a difference Taxiing a He-111 with 3.6T bombs and 1T of fuel
Versus empty with only 200KG of fuel (heavier is easier to taxi)

Also there is a initial inertia brake difference and moving 6tonnes (total weight) from parking takes a lot of power but moving empty plane happens under idle almost.
Also Landing a fully loaded (max fuel and bombs) 111 @ more than 180kph and it takes about 1,000m to stop on runway
Empty it only takes about 250m

As for suspension compression the springs and struts seem(look) to work very well and look great i will have to take screen shots and measure the strut rake angles and stuff to compare them.
Now you got me curious ill compare. (Min loadout, Max loadout) and post results later

[[APAF]VR_Spartan85]

Awesome replies! I'm looking forward to your findings

[Finkeren]

I've broken the gear of a P-40 trying to land it with a heavy load the same way I would, when it was nearly empty.

In the end i could not be bothered doing it all scientific like.

So here is a quick compare.
Left Empty bombload and min fuel, Right Max(3.6t) Bombload and Max Fuel

If you hit a line, with the gear drop?

 

 

 

I've had a wingman experience this when shot up.  His gear just spontaneously lowered and failed to respond further.  I've only had my gear fall out of my wing when I tried to lower them after taking battle damage or snap after/during landing.

In order:

No, there is no granular hydraulic systems model

No, has been confirmed by the devs a few times despite community "experience." They would like to do this but it isn't implemented and never has been.

No, no redundant systems modeling.

No, no heating/locking/etc.

 

IL-2 has a wonderful foundation on which to build on these things. I guess all we can do is hang out, participate in discussions, purchase/promote the product and hope for things to come.

I have been shot down hundreds of time and shot down hundreds as well in BOX. I have never seen a gear failure as a result of gun damage. I truly believe the people that think this has happened are mistaken. The only thing close to gear damage I have seen as a result of gun fire is the gear doors being ripped off.

 

As I'm aware the only gear related damage is due to hard landings, having the gear down at high speed and the doors coming off as mentioned above.

[=TBAS=Sshadow14]

You can be shot up in the 111 and only 1 wheel locks into place.
Also the tyres can fall off when you lower gear

[SCG_Space_Ghost]

To reiterate, it has been confirmed by the devs several times that gears dropping due to hydraulic damage, gears sticking up due to hydraulic damage, etc. is not modeled. Similarly to a deeper simulation of fuel tank management/damage, the team indicated an interest in implementing hydraulic damage features should time/resources permit in the future.

 

Statements from the devs regarding unimplemented features are conclusive on the matter.

Right. This happend to me yesterday on WoL with my Bf-110E at landing approach. The left gear was dammaged by flak hits before and stuck in the wing bay. Very impressive. So,some kind of hydraulic failture must be modelled.

No, it's not.

Damage to the hydraulic, pneumatic or electronic systems is not modelled yet.

 

From a member of the Testing team.

 

Are you able to confirm that mechanical damage (assume to mechanical uplocks) can make a wheel/undercarriage leg drop/deploy on aircraft where gear lever would be in neutral position, and not held up by positive hydraulic or pneumatic pressure.

 

Although rare, I am sure I have seen this happen, but now I am doubting myself 

 

Cheers Dakpilot

 

 

 

I've never ever seen that in the past 3 years. So while i can't confirm that it's not modelled, i highly doubt that it is.

 

 

 

I've never seen that either.

 

 

Same thread. https://forum.il2sturmovik.com/topic/26882-landing-gear-or-flaps-and-other-damage/?hl=%2Bgear+%2Bdamage&do=findComment&comment=426895

 

Unfortunately I can't find the thread right now but a year or two back Han officially confirmed that these types of damages aren't modeled - if anybody wants to try to find it, I opened the thread in 2014-15 some time.

Im not aware of failures but I do shot off some gears and this is guaranteed kill even if enemy escapes​ and do not finish sortie in the air. Edited June 9, 2017 by 307_Tomcat

The gear being damaged when down is a different case where they will jam down or maybe get shot off.

 

Once it is locked in the up position im 99.99% sure no amount of damage will cause them to drop.

Yes you can shoot off other people's gear, but you cant damage them, making them go from up position to down position. (Like hidraulic damage)

Screencap!

 

Does look like some undercarriage...

A couple of nights ago my I-16 locked its gear with one wheel completely extended and the other halfway. I can't honestly say what caused the damage. It could have been enemy hits but it's possible I was overspeeding and that damaged the gear (but then the damage wasn't symetrical). 

 

So, don't know, but I've always found this sim to have more features "under the hood" than people expect.  So my guess would be that gear damage is modelled. (But my guesses are seriously crap, so...)

[=TBAS=Sshadow14]

yeah we not talking about hydraul failure talking about mechanic damage..

I have had many times i go to lower gear and only get 1 green light in 111 or i get 2 greens then i land (very soft greese like 0.2m/s impact) and gear collapses but most times i notice this as i land so gentle i just hold that wing off the ground until i loose aileron control as plane slows..

Have watched a 190 come in to landing (i have a recording i think)
He had pressed gear button but they were only 1/4 way down and flapping up and down from closed to 1/4 down (they would not extend)

If you cant find the post maybe the retracted it as it was false info

[sinned]

I also had landing gear failures due to damage.

 

I was shot and one of landing gears came down and stayed down many many times.

Yes brakes also fail. I use mfg rudder to toe brake. High quality rudder.

When i am shot badly, brake pressure is sometimes absent on one or both gears.

I had similar experiences with JU88.

Thx. God to know I´m not the only one with this experience

Landing gear fails to lock down properly. I had the issue in a damaged IL2 couple times. I even check in the replay. I move the lever up and down and didn't lock properly due to the damage. So this is represented in the game. Mechanical failure.

With the il2, I just remembered something fun about the original il2 sim,

In the training tracks with the il2 when extending the gear it was necessary to wiggle your wings to bump the gear into down lock.

I wonder if this is a little nick-nack our sim now has too?

 

 

Also, glad that we can agree this is more of mechanical malfunction due to damage and not arguing it is hydraulic implementation..

Soon hopefully it will be.

 

Space ghost, thanks for the backtracking on dev diary. And others for photo and video contributon to the subject
