Technische analyse van Fewwawi

Posted on February 1, 2013
Ferrari launched its car, the F138 in Maranello today. The team made it very clear that it intended to start the season strongly, unlike last year, where it played catch up to the McLaren and Red Bull cars in particular.
In overview, the Ferrari F138, as presented at the launch, is similar in concept to last year’s model and does not show as many detailed changes as the McLaren, released yesterday. The stepped nose has gone, which is eye catching, but not hugely significant. The main work appears to have gone into the rear of the car and there is a clear emphasis on thermal management with the tyres and on improving pit stop speed with some intricate detail changes around the rear wheels.
Technical director Pat Fry said, “This year’s car is more of an evolution than a revolution, based on similar concepts to the F2012 and in all the little areas of performance where we think we can gain something, we have looked for those gains.
“The car has changed in subtle ways, some areas more than others, but in general, the F138 is a development of last year’s car.”

It is slightly surprising, given how important this season will be to Ferrari, that the car does not show more changes. They may be concerned, having seen the McLaren yesterday, that their Woking rivals have changed so many things on what was already the pace setting car at the end of last season.
Ferrari will no doubt have many updates in the pipeline for winter testing this month and the early races. They may have some exciting developments which they don’t want to reveal at the moment.
But from what we have seen in the last 24 hours it looks like they are going to need them to stay with what looks like an improved McLaren.
Last year Ferrari started the season on the back foot. They had problems with correlation problems between their own wind tunnel and the Toyota tunnel, which hurt their development. The only development items that worked were the ones which came from the Toyota tunnel. It was down to Fernando Alonso to do a lot of hard work behind the wheel to grind out results to keep them in the game.
The car was pretty good at looking after its tyres, but lacked downforce in comparison with the McLaren and Red Bull cars.

The F138 in detail
There are not as many obvious fundamental changes in concept as there are with the McLaren; the front suspension is still pull-rod, as it was last year and as the new McLaren has moved to.
At the front they have gone with a non stepped nose and modified pillar design. The treatment is well done; the front wing in launch spec is similar in concept to last year’s. The turning vanes under the nose are retained. McLaren has removed them, interestingly.
The front wing design is similar to last year’s. They did not have any nose “cameras” on the launch car. Last year they moved these cameras to in-between the pillars to get more front aerobalance – no doubt they will be there for track running.
The under-nose is heavily contoured and the slotted turning vane is still there, as last year. This is a component, which was not present on the McLaren yesterday, which had been there last year.

The area around the cockpit and the roll-hoop is similar to last year’s. This whole section of the car, including the side pod and associated turning vanes, is very similar to last year, which is slightly surprising.
There is a secondary air intake once again behind the roll hoop, which could be for the passive double DRS system. This is a difficult thing to get right, as Lotus showed last year. Ferrari had one working at the Brazilian GP at the end of last season and this year’s model looks similar.

The rear of the car: The main area of change
There has clearly been a lot of work done at the rear of the car, aimed at tyre management and faster pit stop times. The rest of the rear has been modified, there are updates to the rear suspension and there are some very interesting detailed changes such as the rear wheel geometry which has changed with a new spoke pattern and detail around the wheel nut – maybe for enhancing thermal management of the tyre and brake cooling system and also to speed up pitstop times.
“We are trying to improve our pit stops still further and we have made some changes in that area,” admitted Fry. “Hopefully we can gain another couple of tenths off our pit stop time. On average, we were consistently the best in this area last year, but you cannot afford to stand still, otherwise you find yourself dropping behind.”

The brake duct scoops have also been developed, especially the rear geometry, which probably ties in with the rim change.
Tyre thermal management was key last year and the really interesting changes around the brake drum areas are only visible with the tyres off so we will need to wait a while for spy shots from testing to see what changes have been made in these areas.
The exhausts presented today are similar to last year’s. The definitive exhausts will only be seen at the final Barcelona test (Feb 28 to March 3).
The exhaust channel geometry looks very similar too, but it would be interesting to see if they have kept the same exhaust pipe diameter for their Coanda system. As a rule, the narrower the pipe the greater the Coanda effect as the exhaust gas is attracted to the surface through the channel and down to the diffuser. But a narrower pipe means a slight loss of engine power, so there’s a decision and a compromise to be made.
This is an area that will undergo extensive change and if Ferrari has had some breakthroughs, they were not wanting to show them today, so they rolled out something similar to last year.

The rear wing has been highly developed and now is very intricate with a new end plate design with trailing edge slots and a revised, smaller DRS actuator pod and revised upper rear wing element flap geometry around the same twin Slot Gap Separator locations, aiding efficiency.
There is no lower beam wing cascade but this has probably just been left off for just the launch.
Overall, it’s a more understated car that the McLaren and they must hope that they have plenty of significant steps in place prior to the first race in Melbourne, if they are to start the season on the same level as the McLaren.
Fry alluded to this in his remarks that the launch car is not representative of where the evolved car is in the wind tunnel at this point, “We cannot hide the fact that, aerodynamically, the launch car is a long way behind where we are in the wind tunnel today,” he said.
“We will have a better idea of what our true performance level is come the third test but I’m not going to be happy until we are clearly quickest.”
All eyes now on the Red Bull, which will launch on Sunday, to see if Adrian Newey and his team has come up with something special, as it did in 2011.
Testing begins next week in Jerez

Grappig eigenlijk dat de Ferrari mannen een half seizoen bezig zijn geweest met hun eigen windtunnel te begrijpen.

mclaren launched its new 2013 challenger today, an evolution of the 2012 model, which was the fastest car for significant parts of the season, including the beginning and end.
On the face of it, the new mp4/28 looks similar to the 2012 car, but there are several very significant changes and it takes what was good car and makes it, in all probability, even faster. They have made changes which give them a lot of scope for development as the year goes on.
It is a strong gauntlet thrown down by the woking team to its rivals red bull and ferrari in particular.
They have wisely left unchanged many areas, where there were only small gains to be had; instead they’ve focussed on several key areas where they have already found gains and will find more as the year goes on. This car is all about maximising the air passing under the car and around the side pods down to the rear of the floor and the diffuser, which is where the most downforce is to be gained.
The main changes are the front suspension, the higher front section and the sidepods. But there is a lot more besides. Here is our analysis.

from the front
the front wing is the same as last november, before the us grand prix. This is for launch only and will not be for the first race.
The first area of interest is the front brake ducts, which are quite different. Last year the ducts had few vane ad-ons. This year they are more angled to the front wing. This is going to be a real area of development given the change they have made to a pull rod front suspension, of the kind used by ferrari last year.
This is a fundamental decision and one which they are committed to for the year. The reason why they have switched is because they wanted to raise the front section of the chassis, to improve the air flow under the car and between the chassis and the wheels. However when you do that you raise the centre of gravity, which is a bad thing. You counteract that by using pull rod suspension, which pulls the centre of gravity down again.
Under the nose, the 2012 car had a set of turning vanes, which directed the air down to the diffuser and were quite powerful. They are not on the launch model. It’s likely they will add for testing and race, but if they don’t it means that they are very confident about the connection between the front and the rear.
With the front suspension change, they have had a complete rethink and it opens up areas of aero development outboard and in interaction under the nose.
It’s a long distance from front wing to rear of floor and you need to control that flow.
It’s hard to see it, but the raised nose has a vanity panel, hiding the stepped nose we saw on the lotus

big changes to side pods
the shape of the side pods and the side vanes has changed. The vertical vanes more simplistic, they used to have two, now there is only one.
Outboard of the side pod, the detailing is extreme and you can see it runs the length of floor, undercut and very sculpted; this is a very extreme treatment.
What mclaren is trying to do with this area is to create a skirt of air. Air passing through here will create strong vortex shapes and rotational flow to provide a seal of air, crucially so that everything under the floor stays there at all times and does the maximum job at diffuser, which is where the real downforce gains are to be had.
This area of the car has met with gasps of approval from engineers. It’s really nice work.

coanda exhausts
last year there was a lot of work done on the exhausts to get them to channel gas pressure down to the diffuser. Here the channel looks similar to 2012, but the floor behind it is a dummy for the launch, it’s surely not what they’ll use in test and race. It is very simplistic.
Given the complexity of the rest of the detailing, such as the side pods, this looks like a dummy panel and it will be interesting to see what they do here in testing and at the first race.
The rear wing is from last year, which makes sense; there is more to come in this area. Likewise, the roll hoop intake is same, there is not much to be gained here, so they have left it and focussed on where the gains can be had.

likely development areas
this will be a development race with the other front running care to win the title. Mclaren should start strongly with this car. But they will clearly be working hard to bring more performance in particular to the front brake ducts, the air flow under and around the car, the rear floor and the front wing.

the launch model has nose pillars back under front wing, which is interesting. Front balance is always an issue with this generation of f1 cars. Mclaren were pushing for front balance in the final races of 2012, often adding flaps and other devices to achieve balance. Here they have addressed that.
Mclaren do not have a passive double drs device on the car (as pioneered by lotus past season) and although they are investigating it in simulation, they have no immediate plans to bring one onto the car. There is speculation that the ferrari will have one when it launches tomorrow.
A lot of this work was done in the toyota wind tunnel, which they have had to share with ferrari – so the correlation will be the same as ferrari’s correlation. It is a very good tunnel. Mclaren has been subletting its own tunnel to marussia and is believe to be building a new one. But it will be interesting to compare this mclaren with the ferrari launched tomorrow, as uniquely they were designed in the same tunnel

Mijn voorspelling voor de winter tests: Ferrari en Mercedes matig, Redbull wisselvallig maar met snelle uitschieters, mclaren gaat sandbaggen.

Zo'n conservatieve ontwikkelingen voor het moment

Ben vooral benieuwt naar Mercedes en Lotus.

De snelste ronde vorig jaar in week 1 was 1.18.419. Een positief teken aan de wand voor Ferrari?

[Philippe_RS]

Pedro de la Rosa had vanochtend de eer om al eerste geconfronteerd te worden met een brandende F138.
Na slechts 2 rondje op het circuit van Jerez werd de Ferrari iets te heet en vloog hij in brand.
