Volkswagen razmislja o uasku u F1

To je bila prica i pre par godina ako se secam... Vise bih voleo da udju zajedno sa Audiem i Porscheom, da se zovu Auto Union, kao nekada davno, u lepim vremenima, kad su tockovi bili tanki, a vozaci debeli...

[MarkedOne8]

Evo me, aj da spamujemo XD
Prvo, MekLaren se odrekao čini mi se onih krila na hladnjacima.Drugo, nemaju grbu na prednjem delu i mislim da ni jednom timu nije potrebno da imaju toliko visok prednji deo kad može da bude iste visine, samo da se stanji tu gore kao što je na MP4-27.

[Vanja #66]

Dakle, MP4-27 je predstavljen, vrlo je lep, gladak, NEMA GRBU, ali nema ni onih L sidepodsa...

Gladjuci slike, cini mi se da je prednje krilo stare specifikacije, ali zadnje je izgleda novo... Kad nadjem lepse slike mocicu da potvrdim, wvaljda necu morati opet da izedem svoje reci...
Sidepods su mi mnogo kockaste, ali brzo prelaze u krivinu i vode do vrlo interesantno postavljenih auspuha, ako me oci ne varaju... Oni idu sa strane, ka zadnjim tockovima, umesto ispod zadnjeg krila... To je dobro, ako su zakrilca kod kocnica dobra i mislim da moze biti korisno, mada nije iskljuceno da gasovi gotovo sasvim zaobilaze bolid... Zadnji deo mi deluje jako cist, ali ne nalazim dobru sliku da vidim kako izgleda ispod zadnjeg krila...

Sve u svemu, vrlo cist, vrlo elegantan, nos je resen namenski, ali nedostajace mi L-bocne caure...

EDIT: prednje krilo je specifikacije iz Inidje, verzija za Hamiltona... uporedite sa ovom slikom, cini mi se da jeste...

http://www.formula1.com/news/technic...1/863/911.html

U odnosu na skice, deluje dosta sire u odnosu na 663, izgleda da su stvarno isli na dijetu u Ferrariu.
Bocne caure (da li mogu tako da se nazovu?) me podsecaju na Virginove prosle godine... Jel Marussia bese sa njima potpisala ugovor o tehnickoj saradnji? Nisam mislio da ce ta sardanja ici u smeru Marussia->McLaren...

[MarkedOne8]

Stavili su nešto na difuzor.Ne znam šta je to, da li neka plastika ili ko zna šta, ali tako im neće izgledati difuzor na stazi.Što se tiče auspuha, na jednoj slici vidim samo rupu na ravnoj površini a na drugoj vidim kao dimnjak sa strane.Zaista ne mogu da razaznam šta je šta kad su u pitanju detalji jer se ta njihova srebrna boja toliko sjaji...Aha, sad vidim.Stoje malo sa strane i totalno su obgrljeni tako da nema nikakvih izbočina.Ugao cevi je između 10-30 stepeni ka gore, a dok se bolid bude kretao ugao pod kojim budu izlazili gasovi biće dosta manji tako da bi ti gasovi mogli da idu na krilca od kočnica.Tu se stvara problem jer bi taj vazduh iz izduva trebao da nišani relativno male površine tih krilaca na kočnicama.Praktično bi to bilo izvodljivo samo na pravcima i to pri većim brzinama.U krivinama zaista ne znam kako bi izveli da ti gasovi pogađaju baš tamo gde je potrebno.Isto tako problem je ako bi previše tih gasova doticalo zadnje gume koje bi se više grejale i više trošile.

[Vanja #66]

Malo sam ustrelicio ovu sliku sto je Iceman ostavio... To sto si napisao MO*, mislis na crvene strelice, ako sam dobor nacrtao... Ali, kao sto si rekao, mozda se desi u krivinama da izduvi idu plavim strelicama, direkt u gume. Ko zna, mozda pri manjim brzinama moze da odrzava temperaturu guma tim izduvima? Kolika je temperatura na izlazu iz auspuha pri nekih 10 000 RPM?



Jesi li na ovu zutu plastiku mislio kod difuzora?

[bice]

Lepo izgleda McLaren,samo mi mnogo ruzne ove zute gume Pirelija

[MarkedOne8]

Da, na to što si obeležio žuto je difuzor, ali idi pogledaj na f1.com onu sliku od pozadi pa ćeš da vidiš koliko prosto izgleda da je to neverovatno.



Mislim da je ovo bolja slika za analiziranje u krivinama jer imamo napadni ugao otprilike kao što i vazduh ide na bolid u krivinama.Ova slika konkretno bi se odnosila na skretanje u desnoj krivini.
Nisam aerodinamički tehničar i nemam aero tunel da potvrdim sve te sitnice, ali otprilike bi ovako išlo.
Svetlo plavo su izduvni gasovi na pravcu, a narandžasto u krivinama.Svetlo plavi gasovi idu sasvim fino tamo gde trebaju (krilca zadnjih kočnica) i time stvaraju potisak.Narandžasto obeleženi izduvni gasovi bi pod uticajem čistog (plavo obeleženog) vazduha bili usmereni ka zadnjem difuzoru.Tu bi se možda upleli mlazovi čistog vazduha od napred (zelena fluorescentna boja) i blago bi onemogućavali skretanje izduvnih gasova ka difuzorima i više usmeravali na kočnice.
Ovako otprilike:
Vazduh prelazi preko radiatora i zbog izjednačavanja pritisaka se spušta ka tom skrivenom džepu gde je nizak pritisak i prelazi baš preko cevi za izduv.


Čuo sam da su govorili o gubitku prijanjanja.Verovatno su mislili na produvane difuzore tako da sada moraju da se izmišljalju čuda da od skoro standardizovane situacije neko napravi nešto malo što može puno toga da pruži.

[Vanja #66]

Da, ja sam jednostavnije to prikazao, ti si objasnio sta je ostalo... U principu, ako je tako, onda bi gasovi mozda isli na zadnji tocak koji se nalazi sa unutrasnje strane krivine, samim tim bi ga i malo zgrejali, jer on se sporije vrti u krivini od spoljnog tocka... Stvarno je steta sto moraju da se traze sitnice koje odlucuju o stotim delovima sekunde, a ne da mozemo da vidimo 12 potpuno drugacijih bolida.

Generlano gledano, MP4-27 je dosta jednostavniji na prvi pogled od prethodnika, a u McLarenu su rekli da imaju zelju da ove godine idu mnogo hrabrije sa dizajnom nego ranije, da su im prethodnih nekoliko bolida bili vrlo konzervativni i da sa ovim igraju na granici pravila...

Jedva cekam da Sone postavi neku dobru reviziju, bas da vidim sta su jos ljudi primetili.

[MarkedOne8]

Mali rezime:
- Novi bolid ima očigledno kraće međuosovinsko rastojanje.
- Radiatori su većeg poprečnog preseka ali su kraći.Lično mislim da bi bilo bolje da su duži a manji u poprečnom preseku.
- Novo zadnje krilo.Izmenjeni ,,endplatesi".Donji endplatesi su dizajnirani sa prorezima tako da je površina krila praktično povećana time što su uštedeli prekoračenje dozvoljene površine.Blago povišen glavni profil tako da DRS procentualno zauzima veći deo zadnjeg krila nego prošle godine.
- Dorađeno prednje krilo.Lično mi se jako dopadaju ,,endplatesi" jer u krivinama omogućavaju vazduhu da ulazi sa strane i da nastavi pravo preko glavnog profila.Takođe, tu je i malo veći napadni ugao nosa.

New McLaren F1 car a 'complete rework', according to Tim Goss

By Jonathan Noble

Wednesday, February 1st 2012, 13:28 GMT

McLaren says its new MP4-27 is a 'complete rework' of last year's car - despite its outward appearance pointing to it being an evolution of its 2011 contender.
After the covers came off the new car at McLaren's Woking factory on Wednesday, the main focus points of the MP4-27 were a nose step that was less extreme than some had expected, and the positioning of the exhausts.
Tim Goss, McLaren's director of engineering, said that although outwardly the car was an evolution of the MP4-26, it was in fact totally different under the skin.
"We have set ourselves tough and ambitious targets, and we aim to deliver those by the first race and have a championship-winning car," explained Goss. "This car is a complete rework from nose to tail, and there is very little that is carried over. A bit of the fuel system is the same, but almost everything else on the car has changed.
"There were a few features we have pushed quite hard from the beginning of the project. I am proud of the whole team and the efforts so far, and from now we go to the next phase of the project which is really wringing the performance out of it. We have a good track record of that – we have big plans, upgrades for the front wing, rear wing, floor and bodywork are already planned."
Technical director Paddy Lowe said that the nature of modern regulations makes it difficult for teams to deliver innovation – but that did not stop his outfit believing it had made a good performance step with the car.
"The regulations are trimming us into narrower and narrower boxes," he said. "We don't see big radical changes from one year to the next year.
"This car looks very similar but underneath a great deal of changes have taken place. Every part has been assessed for weight and performance. If you add all that up, you get a car that is quicker. Teams are tasked to find that 1% to 2% performance improvement – but nevertheless there are obvious innovations.
"We have done a lot of work around the back end, and there is a lot more tidy packaging there, and we have had to do a lot of work on exhausts. That has given the aerodynamicists a great challenge, not only to find the downforce but also in creating the right balance. You need downforce but also you have to be able to use it in the right area."
McLaren has moved away from the U-shaped sidepods that it ran last year, because the downwash advantage created by that design is no longer relevant now that blown diffusers have been banned.
Lowe also explained that the outfit never bothered investigating the reactive ride height system being pursued by Lotus and Ferrari and which was outlawed recently by the FIA.
"That was in a family of designs that we have considered often in the past, but in our assessment we would not consider that to be legal," he said. "So we did not get involved in what was being done.
"Our view was that it was not something we would pursue, so it was pleasing to see that avenue shut down according to our interpretation."

McLaren team boss Martin Whitmarsh says team has not been cautious with new car

By Jonathan Noble and Glenn Freeman

Wednesday, February 1st 2012, 12:28 GMT

McLaren believes it has not taken a cautious approach to its new MP4-27 over the winter, despite the problems caused by the radical elements it tried in pre-season testing last year.
Team principal Martin Whitmarsh said at the launch of the new car that McLaren is not expecting a repeat of last year's poor pre-season. But he was keen to point out that the team had not opted for a careful approach to its development over the winter.
"This year we have not been cautious but we have found some good performance," Whitmarsh said.
"We have set ourselves some tough targets that if we reach we think we can fight for the championship. We haven't reached those targets yet, but with some work we will do.
"We had, by anyone's standards, let alone McLaren's standards, an abysmal testing period last year. I would be happier not to fight those issues, and we have put a lot of work into this car and we are not expecting a repeat of last winter.
"I don't believe we have been inherently conservative. Inevitably there are creative brains seeking to find a Eureka moment that will bring seconds of performance, but sadly in F1 those moments are limited."
Whitmarsh also admitted that, like most teams, McLaren still has a lot to add to the car between its launch spec and the version that will hit the track in Australia for the season opener.
"All teams will develop the cars so the car unveiled as they pull the cloth back is not the car being used in Q1 in Australia," he said. "There will be great evolution in some teams.
"We have set targets that are tough. It is not just about testing or the first race, you have to improve the car through every single race if you want to win the championship. Providing we have a good car at the start of the season then we should do well."

Sone, alal ti cufte!

Lep je MP4-27, vrlo lep. Sto je MO8 rekao, ne bih ja tu nista dodavao... S tim sto, sto vise gledam, sve mi se vise cini da su auspusi postavljeni tako da su usmereni ka untranjosti bolida, tj. ka krilcima kod zadnjih tockova, zato su onako izboceni, a i po odsjaju bih rekao da je auspuh savijen ka unutra...

I, da, crni dodatak kod zadnjeg krila izgleda savrseno!

[Nebojsa]

Samo malo da se izduvam, pa cu i ja nesto napisati, ima nekih zanimljivih stvari, tri su me posebno iznenadile
- Normalan nos (u odnosu na Keterem i ono sto ocekujemo od Ferarija i Mercedesa, mozda cak i od Red Bula)
- Potpuna revizija veoma dobrog aerodinamickog paketa od prosle godine
- Pozicija auspuha.
