TÉCNICA Opciones

[Jordi Berges]

A tu otra pregunta... nada tiene que ver con el KERS en el que enchufaban esa potencia extra y sí se notaba enormemente... yo entiendo este sistema de McLaren como "un pequeño rebufo" veremos esa diferencia en rectas largas en paralelo con otro monoplaza y seguramente tendrá que ser muy larga y que hagan un paralelo durante muchos metros para poder apreciarlo. Y por supuesto donde veremos si el sistema marca o no diferencias será en MONZA pero ojito porque allí los monoplazas van muy muy descargados y puede que eso haga incluso que la eficiencia del alerón de McLaren quede reducida aunque también podremos verlo si en realidad McLaren carga un poquito más el alerón que sus rivales ya que en recta gracias al sistema podría igualar la velocidad de sus rivales, pero mejorar mucho curva.

Sobre el tema de la comparación con els KERS lo miraba desde el siguiente punto de vista : Avanzar a cierta velocidad hace que dediques muchos CV a vencer la resistencia del aire, así que aportar más CV (KERS) o hacer que la resistencia baje (F-DUCT) tendría que dar un resultado muy parecido, lo que no tengo claro son las magnitudes.

Ojo, que esto de la resistencia del aire lo saco de memoria de una tabla que vi hace tiempo sobre coches turismo de carrera, así que quizas en la F1 no afecte tanto al tener un diseño diferente. Pero en esa tabla aparecian cosas del orden de varios centenares de CV solo dedicados a vencer la resistencia del aire, y contando que el KERS no daba ni 100 ...

Creo que intentas comparar potencia (KERS) con velocidad punta (F-DUCT) y nada tiene que ver la progresión de los dos sistemas, es distinto, el F-DUCT es mucho más progresivo el KERS... venía a ser "un turbo" durante un espacio muy limitado de tiempo.

Mira las enchufadas del KERS del pasado año...

Renault add revolutionary double floor
On Renault R30 At GP Malaysia Now that the diffusers have become so much more important, the whole floor of the car has a much increased importance towards the efficiency of the whole car. Renault haven't missed out on that aspect and have added a double floor to its R30.

The team introduced a huge aerodynamic step at Sepang, including new sidepod panels, barge boards, a modified diffuser and a double splitter. Apart from its normal function of splitting air from in between the front wheels to the left and right sidepod, the new device also marks the beginning of a double floor. Right above the reference plane is now an open area of about 3cm high. Looking closely at the image you can also see that this floor space is extending under the side impact crash structures and under the whole width of the sidepod. While it is not perfectly clear yet how this air channel is used, the diffuser update that came with it suggests that this is used to feed on of the upper channels of the rear diffuser.

Just as with the underbody airflow, the stream in this channel will be accelerated due to the expansion that happens in the diffuser. As such, air is sucked from the front of the channel, reducing drag at the front while increasing downforce at the rear end of the car.

Lo que esta muy claro, es que el coche no va nada mal y si encima lo maneja un gran piloto..................

¿Alguien podria explicarme el funcionamiento del famoso F-Duct y donde va instalado? Aunque parezca mentira no me ha quedado claro.

Gracias de antemano!

Parece que Mercedes va a aumentar la batalla de su monoplaza... A lo mejor la longitud entre ejes del Sauber no es la principal culpable de su falta de competitividad, lo que sería positivo, ¿no?

Mercedes to increase W01 wheelbase

By Jonathan Noble Friday, April 23rd 2010, 11:43 GMT

Nico RosbergMercedes hopes the longer wheelbase car it plans to introduce at the Spanish Grand Prix will help it get a grip on the weight distribution issues that it has encountered so far this season.

The Brackley-based outfit is set to introduce a major aerodynamic upgrade to its W01 for next month's race at Barcelona, and will also lengthen the wheelbase of the car.

Team principal Ross Brawn has revealed that the motivation for making the major wheelbase change has been prompted by the fact the team miscalculated the weight distribution needs for the 2010 tyres.

"The problem is not actually the wheelbase per se, it is the weight distribution," Brawn said about the motivation for the change. "We got the weight distribution wrong.

"When we got to test these tyres we realised we didn't have the correct weight distribution and we went to the limit with what we could achieve with this car. It is not the wheelbase as such, it is the weight distribution that is not what we wanted it.

"The tyres changed quite a bit... and we didn't have the opportunity to test these tyres, and we didn't have as good a guess of what was required as some of the other teams. So we will have a modification to the car at Barcelona which will give us a better range for the weight distribution that we can achieve."

As well as helping with the overall handling of the car, the weight distribution changes may well help iron out some of the understeer tendencies that have left Michael Schumacher struggling on his F1 return.

Brawn also said that Mercedes will likely introduce a fully working version of an F-duct in the next few events, having begun experimenting with a blown rear-wing in China last weekend.

"McLaren's system, which is driver operated, is quite complicated to get to work properly," said Brawn. "McLaren conceived that car to accommodate the system, and it is not so easy to put it onto [other] cars.

"What we had in China was a simple, passive system. It is not driver operated, so it is not as effective as the McLaren system.

"We are still working on a proper system that we will have at Barcelona or Istanbul. It is complicated to get to work properly, but our aerodynamicists are working on it."

La culpa yo creo que es de una aerodinamica desfasada y de los motores supuestamente capados y poco fiables

Esos son ya los conocidos problemas desde el principio de temporada... que realmente cuesta creer como a alguien como Ross Brawn se le escapan esas cosas o sus problemas estan centrados en ese importante apartado.

Por otra parte cuidadito con Mercedes... que ya anunciaron que para Montmeló presentaran muchos cambios (practicamente un nuevo monoplaza) veremos que tal van, pero ahora mismo no tienen monoplaza para luchar por el Mundial aunque sí esporadicamente por el podio... el que ha sacado petroleo a ese (actual) monoplaza es Nico Rosberg que está MUY BIEN posicionado en el mundial de pilotos y que si a partir de ahora realmente dan un paso a delante no nos queda otra que tenerlo muy muy en cuenta para el mundial.

Ayer tuve una discusión "F1" con unos amigos... y la verdad me empieza a molestar el asunto Schumacher, no creo que esté haciendo el desastre de temporada que algunos le atribuyen, que esté en baja forma o que tenga que arrepentirse por haber vuelto... A mí hasta ahora me han demostrado que el Mercedes no está a la altura de sus rivales, que Schumi tiene lo que hay que tener, y que en cuanto caigan 2 carreras más... ya hablaremos, y sobretodo... que Rosberg es uno de esos pilotos que va a salir en muchas portadas en los próximos años.

PD: como tengo que verme... defendiendo a Schumi, ante los que durante muchos años me refregaron por la cara sus poles, victorias, títulos y records!!! de él y de Ferrari ... al final va a ser verdad lo de mi paranoia!!!

La sensación que transmite Schumacher a mí tampoco me parece mala, o al menos, no tan mala como la que están proponiendo algunos medios acusándole de arrastrarse o rozar el ridículo. Creo que le está costando entrar en la liza de los de arriba pero puede deberse a problemas de adaptación. Sin embargo, también reconozco que si en vez de Schumacher fuese otro piloto sin su curriculum la paciencia que tienen con el sería mucho menor. Se mire como se mire, haber conseguido sólo el 20% de los puntos de tu compañero o estar entre los dos Force India son datos objetivos que pesan a cualquiera.

Por cierto, perdón por el off topic.
