HRT F110 – Rear floor details

 

        Taking a closer look at the rear  lower zone  we can observe the existence of a low height  vertical fence .That fence aims to create a low pressure zone behind it and in the area located  between the inner rear wheel profile and the diffuser external surface . Furthermore that fence together with the flopping upwards floor lip divert the airflow away from the wheel’s profile  reducing drag . Red Bull also raced a similar fence alongside with its floor placed exhaust pipes . The idea is not new as a few years ago Jaguar and Williams used flip ups in this area .

HRT F110 – Streamlining the engine cover

 

             In order to reduce drag  HRT constructed  the F110  engine cover featuring a distinctive V pointed extention to the rear . The shape and the size of the extension is aerodynamically very important as a larger one would create a better streamlined airflow over the car body but would also make the car more unstable to side wings  .

HRT F110 – Bargeboards and sidepod panels details

 

       HRT bargeboards follow a quite common pattern in modern Formula 1 as they feature a stepped upper  profile to cut drag and improve engine cooling  and also have their rear part  to be connected directly onto the turning vanes in order to improve airflow management in this area, while also increasing the structure’s strength .

      The panels are also simple and have their  lower part inclined inwards in an attempt to speed up the airflow close to the sidepod bottoms .

HRT F110 – Front suspension details

       The F110 has a pushrod keel-less front suspension with the steering axis to be placed in front of the upper wishbone instead of being housed inside it . This configuration still offer less drag and furthermore a greater freedom in suspension geometry .

HRT F110 – Airbox area details

 

           Mc laren in 1998 was the first team to remove bodywork from the area located  under the airbox inlet and behind the driver’s helmet so as to reduce frontal surface and hence drag . Since then the morphology of this crucial area evolved a lot and many different paterns of the Mc Laren’s original idea are  seen .  The two pillars in HRT case are for strenghtening the structure and to meet FIA minimum width rules in this area . The airbox inlet itself has a circular shape and feeds  engine’s intake port  with high pressure air .

HRT F110 – Periscope exhausts configuration

 

        HRT has classic periscope style exhausts , a design first featured by Ferrari F310B back in 1997 . This configuration permits to build  a much slimmer rear car end  but effects negatively the function of the beam and rear wing if not arranged properly . The 2010 trend about exhaust configuration is though the EBD exhaust blown diffuser design and thus  periscope exhausts are considered to be old fashioned now .

HRT F110 – Splitter details

 

       HRT features a simple splitter which visually seems not to carry a large amount of ballast . A vertical support is connected on the splitter to ensure structural stiffness . Splitters in general create a Bernoulli effect under the car lowering further the underbody air pressure and boosting downforce production .  

 

HRT F110 – Two rear wing specs for Bahrain

 Sakhir – asymmetric wing , tested only

 

           HRT (like Minardi in the past) did not hesitate to risk at Bahrain by presenting a remarkable asymmetric rear wing profile . Budget limitation can sometimes make mechanics to walk on alternative unexplored paths seeking performance boost . The asymmetric wing featured a larger semi left profile .    

 

                Why an asymmetric wing ? Because Sakhir circuit features the greatest number of right turns in 2010 calendar . It has 13 right turns and 10 left turns  and thus a larger semi outer to the turn profile  would provide a larger amount of downforce as it is exposed in a stronger airflow in a right turn than the right inner smaller section  ( keeping in mind that a car follows a circular orbit at turns for simplicity with of course variable radius )   . Moreover a half oversized profile would also produce half drag from a respective larger symmetric wing in straights.

 

   Sakhir – race symmetric spec

 

           Nevertheless the asymmetric wing after Friday testing did not offer the expected aero gains and was abandoned at race  in favor of a more conventional symmetric design .

HRT F110 – Bahraini front wing details

 Sakhir – tested version

       HRT run a rather simple double profiled wing  with the wing ‘s outer extremities to be raised upwards to increase the air passing under and close to the endplates . The upper additional slotted profile is quite large having in mind other teams designs to provide as much downforce as possible  . The endplate itself  can be viewed as a combination of two vertical plates , inspired by last year two elemental  Brawn’s endplate . For race a black colored tab was added across the  second plane trailing edge to boost downforce production .  In generall HRT  and Virgin wing can be regarded as the most “simple” and dated front wing designs in 2010 grid .

HRT F110 – Car livery change since Spain

 

    HRT might  not had the budget to present radical car changes at the first 2010 European race at Spain but instead  launched  a revised car livery theme with white-less stripes and also with the white color removed from nose and rear wing surface in favor of red and dark metallic gray respectively .

HRT F110 – Inboard mirrors since Spain

  pre- Spain

    HRT was another team to reposition its rearview mirrors inboard since Spain to comply with the new FIA mirror outboard ban regulation .

HRT F110 – Front brake ducts : Bahrain to China

 

      The team used semi closed front brake ducts at Australia . HRT has really large brake ducts ,  probably oversized than what really needs for brake cooling . A cheap and fast option i guess is to semi cover them (to reduce drag)  if less cooling is needed   instead of constructing new smaller ducts which fit  for certain  race demands .

 Melbourne

  Sepang

        The semi closed duct configuration was retained for Malaysia .

  Sinopec

         At China the ducts were closed further having now a smaller inlet available to channel air into the braking system .

HRT F110 – Nose cone details

   The U shaped raised front upper chassis part creates an air channel  over the nose and is inspired by 2009 Red Bull RB5  .

F110 Diffuser

Launch spec

       The HRT F110 diffuser  looks rather simple compared to top teams and it is a double deck design .Simplicity is not always translated as a slow design but for HRT it actually means this . Apart from the central zone the side area have two vertical fences , with the closer to the central zone one to be longer , dividing it into three channels .
