About Ka-50 nose wheel

[yosuke]

Hi. I have a one problem.

 

When I trained for autorotation at the airbase, I got strange movement of nose wheel.

After touch down and reduce speed, nose wheel began to sway violently from side to side.

Then, nose wheel got broken.

 

My friend has same problem.

 

I tried again and again, but nose wheel got broken.

I checked wheel brakes "off" and followed the manual.

 

In previous DCS versions, I did not get this problem.

 

I think this nose wheel movement is very strange.

This problem is bug?

Sorry. I forgot to write my PC spec and DCS:World version.

 

DCS version: 1.2.5.16508

 

PC spec: Intel Core i7-3770K 3.50GHz, 8GB RAM, Geforce GTX560Ti 2GB, Win7 64bit.

 

Thanks.

looks like u landed to hard broke the gear linkage.

monitor decent rates gauge when landing.

the front wheel is kind of glitchy, if you start rolling and beyond a certain speed it will start to glitch out and go from full left to full right several times a second and then it will brake off, has to do something with the fact that it doesnt have steering.

gears are not built for forward high rotation ground speeds.

The KA-50 has a castering nosewheel, which means that you have no direct control over it. Steering is accomplished by the pilot setting the rudder pedals and then squeezing the handbrake on the cyclic stick to differentially brake the main gear. The setup is very similar to what exists on the L-39. I'm sure that other Eastern Bloc aircraft exist with similar nosewheel setups, since the two aircraft came from completely different design bureaus (and countries, even).

 

Keep weight off of the nosewheel during high speed. You shouldn't be slamming it into the ground, either. It isn't as sturdy as the main gear.

Thank you for many reply and tips.

 

I think air speed was too fast, when nose wheel touch on the ground.

I had air speed about 80-100 km/h at the landing.

 

I will practice more for touch down slowly and softly.

It's classical shimmy.

[seikdel]

Yeah, the flight manual says to aim for a touchdown speed of no more than 80kmh.

 

Edit: Headspace: differential braking on the ka-50? I thought it was just the one handbrake for the main gear...

gears are not built for forward high rotation ground speeds.

 

its not even high speed, it starts spazzing out, just try turning or putting the nose forward when taxing and itll start spazzing out completely sometimes it can brake of when because it starts doing 360 rotations really fast.

 

heres a track where it broke off, just by pulling the nose forwards while taxing and it started spazzing out eventually it broke.

Highspeed.trk
