Nose gear broke off on take-off roll!


Ptroinks

Recommended Posts

Do A-10s have extremely fragile nose gears? I was taking off from Beslan (Smerch Hunt mission), and just as I was pulling back on the stick to take off, there was a loud bang, and the nose pitched up violently.

 

The screenshots show my A-10 just before my nose gear "exploded", the instant it happened, and then how much it made the aircraft pitch up. Is this some kind of bug?

What was your airspeed? Also did you disable NWS at 50kts?

Don't know why NWS would have anything to do with it.

 

It's SOP to disengage it at around 70 knots to prevent over steering/accidentally breaking it. I've heard people report they were unable to retract the nose gear due to disengaging it too late.

The screenshots in this thread looks like he's having no problem at all lifting the nose, too.

I can confirm that this happened to me as well once, and I'm certain I had disengaged the NWS. I did pull back on the stick more gently than usual on that occasion to releave the nose gear of stress. But apparantly the end result was quite different.

 

I'll see if I can replicate it tonight when I'm home.

Shoot, haven't seen that since Nellis in the Beta's.

 

I'm sure it is hard to pin this one down, as some seemingly invisible entity at certain

airfields seem to cause it.

 

NWS was proffered early on as a possible cause, but never seemed to pan.

 

Some airfields just seem to have `hawg gear eatin' poltergeists...

I can confirm this also happened to me. Wonder if it's related to the "I'm stuck on the grass that has super-glue qualities" that I get if I stray off the tarmac at an airport during an Emergency Landing, which is annoying as once I'm repaired, I can't taxi back onto the tarmac to continue a mission.

I remember my takeoff was also from Beslan when it happened.

Seems I'll be off ghostbusting and take-off improving tonight.

Hmm... Could it be that the grass already has some small friction bug in it, and if the nose wheel on the A-10 suddenly "dips" below the runway textures and "touches" the grass below (My guess is that runway\taxiway textures are placed on top of grass), the sudden friction will tear the nose gear clean off. I mean, it wouldn't even take "super glue grass" to do that. The runway and the grass have different friction values assigned to them in some way (the grass obviously having a higher value), and when the nose wheel comes down a runway doing 100+ kts and suddenly hits grass, the outcome is obvious. If my explanation is correct, that is :).

^^ If that's it, then my suggestion would be to plug in a check into the code to see if there is tarmac at (or near) the wheel coords and set the grass friction equal to runway friction temporarily. This might be easier than preventing the wheel to sink thru the tarmac slightly.

We have similar problems with a dynamical (spring/damper) simulation of a helicopter undercarriage at the DLR.

It isn't that easy to enforce hard boundaries in a numerical simulation with a system of ODEs.

Just happened to me taking off from Beslan in a free flight mission. NWS disengaged at 70kts, doing about 100 kts and bang, there goes the nose gear.

Unlike the posts I have seen with it happening on takeoff, it happened to me last night on landing. I've attached a .trk file showing it happening...unfortunately you will have to fast forward through a lot of stuff to get to me landing though... I replayed the .trk file this morning and it still exploded when I touched down.

I've set up a training mission out of Minvody and I can replicate this 4 out of 5 times taking off from rwy 30. If I hold short of 30 I get stuck at the holding point. To overcome this I need to input a huge whack of throttle but this invariably ends in my nose gear failing on takeoff. Even if I get clearance on the roll and enter the runway without stopping it often happens. Thought I was doing something idiotic.

 

Edit:

 

+- 30% fuel and zero ordinance so loudout is not the problem.

NWS disengaged as per the manual.

 

I'll try get a track of it.

I was told that there is no actual manual for telling you when to disengage NWS, and that you should just do it at your own discretion.

 

That said, another thing that might cause it is apparently over stressing the nose wheel, for example, taxing around corners at higher than you should speeds.

 

 

However the most prominent problem occurs on the runways, that are apparently bugged and fixed for the upcoming patch, where there seem to be invisible bumps that damage the aircraft.

 

They feel like speed bumps, lol, but most of the ones I encountered are not on the runway but the taxiway just before getting on the runway.

I've noticed the same. It does my head in because I'm aware of the problem so I try to take it easy but it still happens sometimes.

 

By the way, ralfi, love your youtube vids! I've been using your trust in your wingman to "sell" the sim to friends.:thumbup:
