Helmet vibration

[Peter Cox]

Do any other aero's suffer significant airflow/helmet vibration at over 100?

This doesn't occur with hat off.

Anyone found a lelmet design that minimises/ eradicates this vibration?

Are you sure it's the right size for you for starters. If it's a bit loose it will tend to move around a bit in an aero'd car. Other than that it isnt a design with fins/ aero bits on it is it?

They're ok if you keep your head facing directly forwards but any cross force of air will cause buffeting /vibration of the helmet/head.

Edited to say mine has been at 135plus many a time and doesn't have any issues (and I don't mind admitting to regular 135 blasts.....the bad publicity in light of Mr Lucky b******d Policeman would not do any government any good)

I get bad vibes with my "lid" on, but only when the visor is open just a little, when I lock it shut the problem goes away.

Oddly this doesnt happen on the bike when I can keep it a little open at speeds over 150 without any problem, must be something to do with the airflow round the westy cockpit!

Hope this helps

Peter your being too modest. You need a bigger head to keep the helmet still      

Now where did I put my coat.......

[Peter Cox]

LOL

Unfortunately, my head is already too big* so the hat fits nice and tight (as proven by the balaclava scars that take hours to dissipate).

I too get visor vibration when it's slightly open, but that's a different matter (this is occurring wlen visor is locked down).

The helmet is a Shark XRF, simple, bulbous & round...no fins.

Maybe it's the specific helmet design?

Scott, what make and model is your lid?

*...that's cos I'm great, and modest too

[Richgm]

Could also be to do with your height. Same helmet on a person taller or shorter than you will get a slightly different airflow so may not get the same problem as you do.  

Try a different helmet and see if you get the same problem. If you do then maybe moving the areo slightly would cure the problem.

I get buffeting at speeds over 90, but it only happens in windy conditions, or in the slipstream of other vehicles.

HJC CL12. Best fitting lid I've had to date

My helmet started vibrating on a blat at the weekend, easily solved.....just did my flies up.

My Simpson Desperado has a chin spoiler which cuts down on buffeting and "lid lift" dramatically

Have you got a light sabre to go with that helmet Nick?

[Nick M]

I might have....

I've almost got the heavy breathing bit sussed - helped enormously by the use of a small plastic cup....

Use thee force lad!!!!

I get a slight vibration when the heavy blaster cannon fires, but apart from that my helmets fine up to 1200 kph in the atmosphere
