Ptroinks Posted March 18, 2011 Posted March 18, 2011 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? [sIGPIC][/sIGPIC]
=Panther= Posted March 18, 2011 Posted March 18, 2011 What was your airspeed? Also did you disable NWS at 50kts?

636_Castle Posted March 18, 2011 Posted March 18, 2011 This might be a no-brainer...but you did disengage NWS at or below 70 kts, right? :P [sIGPIC][/sIGPIC] How To Fix Your X-52's Rudder!
Tnt Snipes Posted March 18, 2011 Posted March 18, 2011 nice... as in... damn its that much realistic... i did not know... yes i would like to hear the issue behind it... [sIGPIC][/sIGPIC]
Lixma 06 Posted March 18, 2011 Posted March 18, 2011 I'm pretty sure it's a bug..... http://forums.eagle.ru/showthread.php?t=68604 The nosewheel gets 'stuck' to tarmac, and no amount of elevator will lift the nose of the aircraft. Eventually it just explodes. Don't know why NWS would have anything to do with it.
636_Castle Posted March 18, 2011 Posted March 18, 2011 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. [sIGPIC][/sIGPIC] How To Fix Your X-52's Rudder!
Mud Posted March 18, 2011 Posted March 18, 2011 (edited) 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.

Insanatrix Posted March 18, 2011 Posted March 18, 2011 I've had it happen before with NWS steering off. It almost feels like the plane's gear gets stuck in mud for a split second. no excessive rudder, no plane carcasses on the runway or anything.
Call911 Posted March 18, 2011 Posted March 18, 2011 Ditto, cpl diffenrt times I've had it happend here too. Scared the crap outta me2 as was'nt expecting it.
Spectre_USA Posted March 18, 2011 Posted March 18, 2011 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.

andyfoot Posted March 18, 2011 Posted March 18, 2011 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.
Mud Posted March 18, 2011 Posted March 18, 2011 I remember my takeoff was also from Beslan when it happened. Seems I'll be off ghostbusting and take-off improving tonight.

Ptroinks Posted March 18, 2011 Author Posted March 18, 2011 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 :). [sIGPIC][/sIGPIC]
PhoenixBvo Posted March 18, 2011 Posted March 18, 2011 (edited) ^^ 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.

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.

Col.Flanders Posted April 25, 2012 Posted April 25, 2012 (edited) 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. Edited April 25, 2012 by Col.Flanders
shabo Posted April 25, 2012 Posted April 25, 2012 how heavy are you? are to over 100% load? I have had that issue if I have an overweight bird with an unrealistic loadout onboard. [sIGPIC][/sIGPIC] www.wargamelabs.com you might need a life if you computer specs are in your sig ;)
Col.Flanders Posted April 26, 2012 Posted April 26, 2012 Happened again. I've attached the track. You'll see when I request takeoff clearance I don't hold short but rather call on the roll to avoid getting stuck at rwy 30 holding point. PS: Note I'm a total newbie so don't laugh at my slightly less than orthodox startup on this one! :Pmivody_NLG_fail.trk
joey45 Posted April 26, 2012 Posted April 26, 2012 Without looking at the track... did you remember to lock your NWS before going past 70 kts??? The only way to make sense out of change is to plunge into it, move with it, and join the dance.

joey45 Posted April 26, 2012 Posted April 26, 2012 Use a bit of trim up and start pulling back a few degrees at around 150.

ralfidude Posted May 6, 2012 Posted May 6, 2012 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!
