a furia di stringere, rastremare, Newey progetterà in futuro una vettura senza pance e un grande airscope

Andr? cmq sempre meglio della HRT o come si chiama.

Ma ? Marko, quello?

[Phoebe4Ever 1]

Troppo estrema.

[Bertoku 1]

Secondo me potevano benissimo correre con la macchina dello scorso anno aggiornata al regolamento 2011

ma quel buco sul diffusore ? regolare?

???? Quale buco?

[ema00 859]

quello che si vede a sinistra della ruota posteriore all'altezza dell incrocio tra ruota e alettone

[ClaudioMuse 3604]

non ? un buco, ? lo spazio tra il flap inferiore dell'ala posteriore e il fondo.

[Pegasus83 0]

qui ormai si vedono buchi ovunque

[Aviatore_Gilles 3087]

non ? un buco, ? lo spazio tra il flap inferiore dell'ala posteriore e il fondo.

 

Non credo intendesse quello

Si riferiva a quel piccolo taglio orizzontale alla sinistra della ruota.

grazie per la fiducia riposta nella mia intelligenza aviatore ha capito quello che intendevo per fortuna

Prego, la mia vita e il mio lavoro mi obbligano a comportarmi da maestro d'asilo

In teoria quello non dovrebbe nemmeno essere il diffusore, ma il profilo inferiore dell'alettone.

Comunque quella fessura l'ho notata anche su altre monoposto.

Red Bull RB7 ? Open Fronted Exhaust Blown Diffuser

 

 

When the RB7 was launched the cars apparent lack of any innovation was surprising. Yet the car ran in its launch guise during the first day of testing. Then, in only the tests second day, the RB7 evolved with a new diffuser and exhaust system. Despite rule changes Newey has found the loophole that allows exhausts to blow inside the diffuser for more downforce. Although the rules were revised for 2011 to try to prevent double diffuser and openings to allow the exhaust to blow inside the diffuser. The rules did permit openings in the outer 5cm of the diffuser, an area where teams have recently split the floor and created raised lip, coincidentally a practice first exploited by Newey on the RB5.

 

In my 2011 trends and solutions post (see http://scarbsf1.wordpress.com/2011/01/27/2011-trends-and-solutions/) I proposed this area could be exploited if the exhausts could be routed there: ? The only openings in the diffuser are the starter motor hole and a 5cm area on the outer section of floor. Exhausts could be routed to this outer section of floor, but routing the large diameter exhausts across the floor could create their own blockage effect in-between the rear wheels. Offsetting the benefit they are supposed to provide.?

 

It appears Newey had the same idea and has presented the modified RB7 with flattened exhausts reaching rearwards under carbon overs (shown yellow in the above picture) these reach towards the outer 5cm of floor and blow under the raised lip in the floor. The fast moving exhaust gas then curves inside and blows out via the sidewall of the diffuser (shown below with the red arrow). Blowing inside the diffuser this way helps accelerate the airflow out of the diffuser and increases downforce. As with last years EBDs they will be sensitive to throttle openings and Renault have assisted as much as possible in accommodating the aerodynamics with a special overrun strategy, to keep the exhausts gas velocity as high as possible without overheating the engine (see http://scarbsf1.wordpress.com/2010/07/10/red-bull-map-q-the-secret-to-the-teams-q3-pace/). Renault were also understanding in developing an engine mapping that would work with far longer secondary exhaust pipes, without losing power or drivability.

 

 

In a strange coincidence with the Lotus Renault team, the exhausts has been extended by up to 1 meter and equally has a flattened oval exit, with the central separator (http://scarbsf1.wordpress.com/2011/02/01/renault-r31-front-exit-exhausts-fee-explained/).

La RB7 ha gi? perso la pinna sul cofano motore!

Ecco, se perdesse anche quell'inutile prolungamento dell'alettone posteriore sarebbe quasi somigliante ad una F1

secondo me ha quella minipinna per fare in modo che entri tutto il logo red bull.. Non credo abbia grandi funzionalit? aerodinamiche una pinna cos? piccola.

[Bertoku 1]

Devo dire che trovo esteticamente piacevoli le monoposto nuove senza quelle orribili pinne a mo di cartelloni pubblicitari.
