imagine if the backend steps out

 

There's something not right about that report.If its for a windtunnel how come the bloke is sitting in front of it on the computer.Won't he get blown away with the fans running???Is it a photoshop,someone having a laugh????Regards,Micky

 

nah there is one with an f1 car on it but the major part is under floor out the way

 

omg how would u get the car down from that?

 

Well it looks like it is braced with 4 ropes of some sort...

 

Did a little more web research and found this

Looks more like it!!

Checkout the over head gantry crane in the background


I would say that's the factory where it's been developed, built and tested, not where it's going to be finally mounted inside a wind tunnel.

.

 

Its not a rolling road. Its a tread mill for cars than failed the Weight Watchers programme

 

Stop the belt very quickly at 180mph and the car will soon come down

 

hand the young lad the engine leads and tell him to put them on lol

 

cool

it's obviously just rigged up so that you can see it and would be built flush with the floor when installed in a wind tunnel

 

looks like a giant belt sander

 

looks like its more for aerodynamics, the video makes no reference to measuring power of the vehicle

 

Aye it literally a rolling road and not a dynamometer.
Wonder if they can create side winds, cambered road conditions, brake tests etc. Probably do very little with regards to handling testing.....seems a bit pointless to me.

 

could it be to test gear ratios to obtain optimum ratios for maximum top speed?

 

No,as the car's wheels are'nt turning the rolling road,its the rolling road turning the wheels.The car's engine would'nt even be turned on when run on one of these.Regards,Micky

 

Hi All

Not a regular poster but read a lot of the threads. Great source of info.

In wind tunnel testing the aerodynamics of a car are effected by the movement of the road under the car and also by the motion of the wheels. In standard aerodynamic work there is probably no need for a fully moving "road" as the difference would be small. I believe it has to do with testing ground effect and under body air flow. The world of racing every little advantage is required and so if the aerodynamics is effected by the road motion then more than likely they will test it. If I get anymore info I'll post.

My two cent worth

I wouldnt like to be that bloke when it skips off the roller

 

lol looks like abig car treadmill!!! the straps holding it down dont look very safe!!! just imagine if they snap!!! ya'fooked then..........

 

Thats just mad.
