HRT F112 Cosworth

[cbbcisace]

Sorry, I heard that HRT start system is new in China.

My English should be better seen as it is my first language!

[charan0790]

he had the same suspension issue in the final practice session which later again developed before the start of the race!!

Back to the front wing I just wonder what HRT are looking for and what they are trying to achieve. The areas where the flowviz concentrates is that where the wing generates drag?? Or are they just looking at the direction the air is being channeled.

There is no decent picture of the F112 diffuser? I couldn't find a good picture of it and also to see the rear brakes ducts too...

I´d love that any armchair aero engineer could explain us, in plain words, the meaning of all that mesh of yellow traces.


P.S. English it´s my fourth language so please, be patient about it

[Petroltorque]

For someone for whom English is their fourth language you put us natives to shame. Its an even more difficult language to write. But I digress.....I'm no aero engineer but I think what you're looking for is the way the traces flow towards the front wheels and tea tray. As a layman it looks like its not diverting the airflow around the wheels properly.

[Lycoming]

There is quite a lot of spanwise flow... not sure what that means for performance though.

I often feel much the same way. I grew up with English; it was spoken everywhere around me; I was taught the specifics of English for 12 years; I cannot speak another language; I still screw up English all the time.

As to the HRT wing, perhaps some comparisons are in order.






I'll try to add more as I find them.

They are just running with a base suspension at present. They hope to have the J Dampers on the front suspesion for Bahrain. They are adding small things every race, small things that may only be a tenth in raw pace, but maybe in race trim a tenth more as we have seen with Williams this year, race trim is worth more than Quali trim.

If it was possible to run J dampers they could expect an improvement. Unfortunatelely J dampers were outlawed by the FIA years back. One would hope to have better information on a technical site. They could run inerters which operate under the principle of keeping the contact patch of the tyres constant.

J-dampers = interters IIRC. I think J-dampers is a term coined by McLaren to keep the purpose (interting) of the device obscured. The outlawed component was the Renault version of it, but they were called something else I think.

I think the same. The illegal damper was Renault's mass-damper. Every car runs today a J-damper

My profound apologies. I stand corrected. Am about to don a hair shirt and adjourn to the local Monastery as penance.....

[element]

From HRT twitter "And Xavi Marcos (Pedro's performance engineer) explains what's new on the F112 this w-end in Bahrain"

So it seems they have new stuff, probably cooling solutions.

[cbbcisace]

Maybe something with the suspension that ESPI mentioned.

[tenali]

I have too say Marussia have made a very good step forward and also Caterham, it would be very very difficult fot hrt to even catch their current car with their hrt f112+, I fear this might be their worst year in terms of relative pace with the 2 new teams???????
