McLaren posljednjih nekoliko sezona traži povratak na pobjedničke staze, gdje su zadnji put bili još 2012. godine kada su do pobjede došli Hamilton i Button. Iduće godine su odlazak Hamiltona htjeli brzo zaboraviti dovođenjem Pereza, ali je to neslavno završilo i Meksikanac je otišao već nakon jedne sezone. Sličan recept pokušali su i 2014., kada je Jensonu Buttonu društvo pravio Kevin Magnussen. On je nakon dugog vijećanja izgubio mjesto zbog dolaska Fernanda Alonsa.

Povratkom Honde u McLarenu se očekuju veliki rezultati, ali prvi testovi nisu obećavajući. Što uopće očekivati od njih u prvoj povratničkoj sezoni kao tandem McLaren-Honda?

McLaren: the power unit Honda needs air

101 Dalmatians ... laps. McLaren for the first time in the winter brings together a useful distance for the development of the MP4-30, although the car of Jenson Button penultina caused the red flag a few minutes after the close of the second day of collective testing in Barcelona.

Effe Tech 1 image you can see the "gills" that have been opened to the sides of the car McLaren to help extract heat from the bellies and avoid overheating that send in crisis the power unit Honda RA615 H.

Although the day the air temperature never exceeded 14 degrees, the engineers at Woking were forced to resort to the openings showy hoping to find a little 'reliability.

Honda: ten tokens to play in the season?

[ link do slike ]

Yasuhisa Arai if the laughs heartily: the manager of Honda R & D has to wait for the Australian GP to know for sure how many tokens have used other manufacturers to start the 2015 season of the 32 granted by the FIA.

Early winter seemed like Mercedes, Ferrari and Renault were to play the majority of the token to prevent the Honda could use during the season remaining third of the average of all the others. Then things changed a lot ': only the Mercedes give up to ten tokens, while Renault and Ferrari seem to have decided to adopt safe solutions because they have yet to reach the' reliability of Gp 5 for each unit and prefer to start the 2015 season with a secure solution that does not make the start of the world.

Of course the reality you know the only and only to audits of Melbourne, but in bad accounts, the Japanese might be in his pocket almost ten tokens to use because opponents have preferred to be more cautious.

Jenson Button today use the power unit RA615 H that yesterday was approved by the FIA in Paris: it will be interesting to see if today will cover the distance of a race without technical problems, given that the potential does not look bad at all ...

Malo o homologaciji Hondinog motora za 2015 i tokenima.

Lady, ne razumijem dio rečenice, pred kraj, u kojem piše "skoro" 10 tokena. To bi, koliko sam ja shvatio, bilo 9 i nešto tokena, znači nepunih 10. Mislio sam da je FIA Hondi dozvolila matematički prosjek neiskorištenih tokena drugih dobavljača PJ zaokružen na manji okrugli broj. Npr. ako to iznosi 9,7( to je skoro 10) trebalo bi biti ipak 9 .

raca, to ti je link sa OmniCorsea koji sam prevela, a btw..., u brdo otvorenih linkova, priljepila sam krivi!!

i Original talijanski

---------------------------
A u originalu rečenica: la Casa giapponese potrebbe trovarsi nella saccoccia quasi una decina di gettoni da utilizzare perché gli avversari hanno preferito essere più prudenti.

šta bi se moglo prevest ovako: Japanci bi tako u đepu mogli imat oko 10 tokena na korištenje, jer su protivnici preferirali bit oprezniji....

Znači ili 9 ili 10..., ali nikako 9,6....
Baš sam na GP-u objašnjavala ovo oko tokena i to ti je jako precizno. Svaki dio pogonske jedinice ima svoju 'težinsku' vrijednost označenu sa tokenima. Ako se ne varam, cijela PJ ima 66 tokena, a ono šta timovi smiju dirat je 61 token. Od toga mogu maksimalno mjenjat 32 tokena. Ako se sjećam kad je Iceman stavio sliku sa tablicom, cilindar glave je nosio 2 tokena. I tako ti svaki dio PJ ima svoju težinu koja je označena sa ljestvicom od 1-3. Znači najmanja vrijednost nekog dijela može bit 1 token, a najveća vrijednost nekog dijela 3 tokena. Kao šta sam već prije napomenula, svaki dio ima svoju vrijednost izraženu u tokenima.

Ako nešto nije jasno, samo pitaj.....

Ne, u redu je. Samo sam uočio taj mali dio kao kamenčić spoticanja, jer, što i sama kažeš, može biti okrugli broj, a kad se spomene riječ almost, quasi, fast ili dr. , ne daje se precizan odgovor.

Konstrukcija ERSa kod Hondinog agregata... čini mi se da su išli logikom Ferrarija, da maknu MGU-h iz V-zone, i time anulirali pregrijavanje istog uzrokovano agregatom:

Prva utrka nakon ponovnog ujedinjenja je prošla. Button je svojim velikim iskustvom nekako dovukao McLaren -Hondu do kraja.
Zaostatak je ogroman.

Mislim da bi osvajanje boda bilo vrlo pozitivno za sve u ekipi, ali vrlo nerealno zbog svih ostalih koji nisu vozili ili su odustali.

Pravo je čudo što su završili utrku, nisam to očekivao uopće.

Button je sa kompletnom utrkom nanizao više krugova nego na treninzima.

Očekivao sam dim i parking kraj staze oko 20 kruga.

Što kažu s Autosporta o Hondinom radikalnom motoru

echnical insight: Honda's radical Formula 1 engine for McLaren
By Craig Scarborough Tuesday, April 21st 2015, 10:19 GMT

Honda F1 engine

In the months ahead of the launch of the McLaren MP4-30, there was a huge amount of speculation surrounding the technology of the new Honda Formula 1 engine.

It's been a troubled start so far, with pre-season testing a disaster and McLaren battling to make up ground in the early flyaway races.

A lot of these reliability problems are the result of Honda trying to steal a march on its engine rivals by incorporating new and unproven technology, as, with in-season development limited, it did not want to start 2015 with a basic power unit set-up that would be hard to improve.

McLaren went aggressive with the aerodynamic concept on this year's car, and that put pressure on Honda to achieve the packaging required for the Woking team's 'size zero' dimensions.

Over the Bahrain Grand Prix weekend, the ongoing problems on Jenson Button's car allowed us to get the first clear look at the Honda unit, showing just how radical the Japanese firm has gone to achieve minimal volume with its packaging.

Honda has split its turbo, but the way it has done so is different to Mercedes, as the turbo sits within the tight confines of the 'V' of the engine, along with the MGU-H.

To fit a turbo into this space, it appears that Honda has pioneered the use of an axial flow compressor.

Rather than a large centrifugal fan, there are a series of smaller fans along a shaft.

This design spins up quicker, although it may lack the maximum possible boost, which is not such an issue in this fuel-limited formula.

Aligned on the same shaft as the compressor is the MGU-H and the exhaust-driven turbine; the latter appears to sit behind the engine and is of a more conventional design. Honda hopes to improve driveability and reduce the size of the envelope of the engine with this layout.

Above the turbo is a compact, low-line aluminium inlet plenum chamber. Inside, the inlets are turned through 90 degrees to reduce the height of the chamber, while still allowing for variable-length inlet trumpets.

More conventionally, the oil tank and MGU-K are located at the front of the engine and under the left-hand cylinder bank respectively.

Finally, and again unconventionally, the ERS module ahead of the motor combines the battery and both control electronic boxes (one each for ERS-K and ERS-H) into one unit.

This creates a lower and lighter unit that requires less space under the fuel tank area, which again aids aerodynamic packaging.

Of course, all of this tight packaging means that there's precious little space for external cooling.

All of the ERS elements will require water or oil cooling, which has led to reliability problems and Honda needing to cap power to keep temperatures under control and prevent coolant leaks via the seals around the spinning shafts.

Although Honda continues to have reliability problems, the fundamental design of the power unit is valid and will eventually become both powerful and reliable.

That will mean McLaren's aerodynamic packaging gains can be fully realised.

McLaren hoping to be fully competitive by end of 2016

Eric Boullier believes McLaren can be competitive this year but is targeting the end of next season to get back to full strength.

McLaren joined forces with Honda at the start of this year but has yet to score a point in the opening four races of the new partnership. The car's performance has improved since the start of the season, but Boullier says Honda is still catching up on the development time it has lost to its rivals.

"We can become competitive this year," he told the New York Times. "We will be regularly competitive next year. I think that before the end of next year, we will be there.

"It's the year and a half that we missed, to catch up. We are building up everything in strength. But the project is extremely ambitious.

"Honda has the commitment to get back, and we - Ron [Dennis] and the McLaren stakeholders - are all putting everything in place to become a competitive team. So that will come. But we just have to catch up, and we need just a little bit of time."

Boullier is confident McLaren's difficulties will not trigger the gradual decline of the brand.

"I know what is happening behind the scenes. Already, as I said, the car itself is not yet a winning car, but it soon will be. Our engine partner will also gain in maturity, and we know we will grow in strength. McLaren is back, no worries.

"The other thing is that McLaren is part of a McLaren Technology Group, where we have a few businesses, like McLaren Applied Technologies, that are working well.

"The series of F1 is driving the brand, and the technology that we're selling and that we're developing around F1 is consolidating a huge business. We're already nearly a billion-dollar-turnover business - not F1, but McLaren. The F1 team needs to stay just F1: back to racing basics."

Da nije to malo daleko? 2017. kreću nova pravila, vrlo vrlo vjerojatno, pa onda ne znam kako su predvidjeli ovo.

..zanimljivo rješenje u auto industriji, izgleda posuđeno iz avio. Očekujem da će to i drugi razvijati s vremenom.

Villeneuve, who raced in F1 with works Honda power for years, says he has little faith the Japanese manufacturer can quickly rise to the front of the grid.

"I worked with them," he said, "and know it can be a very slow culture and one that prevents them from doing certain things."

Alonso, however, says he was happy to take a 'risk' with Honda rather than settle for what could have been more near-successes in a Ferrari.

"With this move," Villeneuve insisted, "Alonso may have ended his career -- he may not win any more titles or even races."

Osobno nikad nisam bio fan McLarenove "crne" faze bolida.. pa tako ni ove antracit. No tko zna, možda na stazi (uživo) bude fenomenalan.

Meni izgleda ko da ga je poplava izbacila. Najljepše boje McLarena su mi 80-e, doba West-a i poslije vodafone. Ovo od 2014. ne liči na ništa.
