It’s rare a technical development passes without anyone noticing and of all teams its surprising Red Bull pulled off that trick in the past few races. As they were seen to have a Mercedes-like Double DRS (DDRS) system in use in Japan. It transpires the system was track tested in practice at Monza and raced in Singapore. Part of the secret of the Red Bull DDRS is that the system is wholly contained within the rear wing. Only the plate over the end of the rear wing flap gave away the systems existence. With this system Red Bull are able to shed even more drag when DRS is open, thus giving them a top speed advantage in qualifying and when DRS can be used in the race.
When the 2012 Technical regulations were published last year the biggest change was around the exhaust position. Since 2010 when Red Bull reintroduced the exhaust blown diffuser (EBD), teams had progressively lowered their exhaust outlets and pointed them at the diffuser to gain additional aerodynamic effect. For 2012 the exhaust position was mandated into a higher position with the exhaust tailpipe pointed upwards. On paper the rules appeared to prevent any exhaust effect on the diffuser. However two aerodynamic effects have been adopted to direct the exhaust plume downwards and recreate some of the blown diffuser effect; Coanda and Downwash. Although initially different teams adopted different solutions and differing amounts of these two effects. McLaren found a way of shaping the sidepod and exhaust fairing to use these effects, which were then able to consistently direct the exhaust plume at the gap between the diffuser and rear tyre. McLaren’s exhaust\sidepod solution has proven to be the most widely adopted and has been termed a ‘Coanda’ exhaust by the media. Even though it’s arguably an inaccurate term, as the downwash effect is probably greater than the Coanda effect in comparison to other sidepod shapes, such as Sauber’s or Red Bull’s.
Congratulations to Serene Tan for winning the prize and to all of you for getting the answer correct.
RED BULL RACING SPY APP BRINGS THE PADDOCK TO YOUR POCKET
Red Bull Racing brings a range of F1 knowledge, driver facts and tasty gossip direct to your phone in the run up to the Japan Grand Prix. If you want to know what’s going on in the Paddock, in the pitlane or on the track, then you need this free app. Bought to you by current F1 world champions’ man on the inside (knowingly dubbed the ‘Red Bull Racing Spy’) this app gives you everything, from results to parties, and behind the scenes pictures to gossip.
The Red Bull Racing Spy, who already has a following on Twitter, brings you closer to the real action in Formula One. The app is essential for any F1 fan who wants a little more information than the average spectator and who secretly loves a bit of grand prix gossip. If the Spy misses something out, you get the chance to quiz him; ask anything F1 related or lay down a challenge and see the responses in the feed.
As well as all the unique features, the Red Bull Racing Spy also brings you the information that you’d expect from any self-respecting F1 app including lap by lap track positioning, race specific facts and figures, driver and constructor championship standing and a full race calendar.
To celebrate, we’re giving one lucky F1 fan the chance to win a Red Bull Racing cap signed by Mark Webber himself, along with an official Red Bull Racing t-shirt. To enter, you simply need to download the app here http://bit.ly/LQlMx8 to find the answer to this question:
As RenaultSport consitently provide such detailed technical explanations, I have posted their Pre-Korea Technical Feature in its entirety below
The torque map is probably the single most important reference map used in Formula 1 engine management. It is the fingerprint of an engine and of critical importance for engine engineers to help optimise the on track engine performance.
With their partnership now in their 18th year, McLaren and ExxonMobil have a long history in developing fuels and lubricants to extract the most performance from the car. ExxonMobil provides McLaren with their race fuel, engine oil, gearbox oil, hydraulic fluid and greases. It comes as no surprise that in Formula1 the fuel and engine oil are developed as bespoke products for McLaren, but the other lubricants are standard industrial products available off the shelf!
Fuel and lubricants are critical in F1; their development not only makes the car go faster, even with the current engine specification freeze. But they also provide early warning of problems to predict problems with wear or reliability.
The relationship between the two companies is very close. The typical McLaren attention to detail extends to a Mobile Laboratory along with a Lubricant Scientist being sent to every race. For the entire length of this partnership, this has been Dr Tony Harlow. We spoke to Tony at the Singapore GP about the work that ExxonMobil conduct at each race weekend.
The paddock at Singapore is a hive of movers and shakers in business and within the sport. One of those people is Oliver Weingarten, the Secretary General of FOTA. The Formula One Teams Association (FOTA) are a group of Formula1 teams, set up to promote their interests and the image of the sport to the fans. In its short life FOTA has always been at the centre of the sport, with its members well known for debating future rules. But it’s also FOTA who set up the Fans forums and manage the Resource Restriction Agreement (RRA). With such a wide brief, we asked Oliver in the first year of his role about FOTA and their activities.
Sauber have been a leader in aerodynamics this year, with the C30 gaining many compliments from other F1 engineers. With revisions to their front wing this weekend In Japan, it seems good time to delve a little deeper into the complex design of the wing. Their current wing dates back to the Spanish GP and has several features unlike any other on the grid. In Japan the wing gained a new winglet added to the cascades and a small change to the main endplate/
Having been discussed amongst the Technical working group for some time, the 2013 Technical regulations have now been published, with a just couple of small updates. The first being the option to fit a simple panel over the stepped nose for aesthetic reasons, the second being the banning of DRS having a secondary effect, as with the Mercedes Double DRS system.
These will not be changes that will unduly effect the development of the2013 cars, which are already well underway, but the former change will make the cars look a little different.
At each Grand Prix we see dozens of Mechanics and Technicians looking after the car, but there’s one aspect of the car that need particular looking after, the driver. At team Vodafone McLaren each driver has their own personal trainer, for Jenson Button this is Mikey Collier. He looks after Jenson’s care, not just through the race weekend, but throughout the year. We had a chance to catch up with Mikey to find out about what special preparation the heat and humidity of Singapore demands.
Singapore, approximately 9000 miles away from the UK where many of the drivers, teams and mechanics started their journey only a few days earlier. Being the only night race on the calendar, Singapore certainly throws almost everything into a whole new perspective when it comes to staying on European time. Everything is turned almost upside down as breakfast is served at lunchtime, dinner happens at 3am and lunch? I’m not even sure when lunch happens, at dinner time? Either way, things here are a world apart from other races and it is vital that not only the drivers, but the whole team can adapt to the race schedule and remain on top form.
Today I met one such man who aims to do just this. Heinrich Grafe is the General Manager of the Conrad Centennial Singapore Hotel (part of Hilton Worldwide), set in the heart of the Marina Bay street circuit. Heinrich has spent the last 14 years managing the hotel and his passion for Formula One shines through when you ask him what he thought when he found out 5 years ago that Singapore would be hosting the sport.
