Mclaren MP4-29 Pre-launch Speculation

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

There is no dump valve/tube, and anything that goes through the compressor must exit through the exhaust.
Bit more reading required before you can find a loophole there methinks :wink:

Seems like if you exhausted pressurized air from the turbo to the atmosphere you would severely detract from the power generating purpose of the turbo.

Reading my eyes out here lol :P

So, if I'm not mistaken, every exhaust gasses must exit through the rear pipe that ends under the rear wing. No smart tricks to be done here.

Then I'm still wondering about the innovative rear suspension, any suggestions on that one? Because I can not really think about any idea which would be " innovative " lol!

And oh yeah, PS: I maybe a bit of a noob on the forum, I did my reading and research, because I have a quite big ego to be a real noob loll :D

The one thing that I can see them doing is having the exhaust exit right underneath the monkey seat. This won't help anywhere near as much as exhaust blown diffuser (EBD) or the various types of coanda exhausts. However it can help to serve two functions. These are:
1. Help generate a little bit of downforce as long as the throttle is open. This is because as the exhaust gases exit the exhaust they want to fill the low pressure area created below and behind the monkey seat. The exhaust gasses will travel up and to the back essentially creating a jet of hot fast moving gasses, there-by creating a bit of downforce. Also as the fast moving gasses (a fluid) travel below the monkey seat they create a low pressure area on the bottom of the monkey seat. This is because of Bernoulli's principle.
2. On the Lotus E21 if you look at the monkey seat you will see how it curves out sideways as well as upwards. This was done to encourage airflow to move out to the sides of the car and fill in the low pressure area behind the rear wheels. If you look at pictures of the rear wing end-plates you will notice that at various races, various teams made the end plates the have an outward curve to them. This has the same effect of helping to move airflow behind the rear wheels and reduce drag. (It also has the effect of slightly reducing the pressure below the rear wing.) Wings operate on the principle of pressure differential between each side to create a force.

The other option and probably less likely to be seen is trying to incorporate the exhaust into some kind DDRS system like Lotus and Mercedes tried out in the 2013 season. However personally i cannot see how this can be done as those DDRS systems operate on using a cars speed relative to the airflow to turn the wing stalling effect on and off. You would not want the driver getting on the throttle and stalling the rear wing.

*edit* wherever i put DDRS, it should read DRD (drag reduction device)

Reports in Italy indicate that the MP4-28, designed by Matt Morris, is behind schedule due to failing the mandatory FIA crash tests.

This implies that the online presentation scheduled for 24 January will not feature the complete and ready to test MP4-28, but rather a mock-up of the 2014 car. This could fulfill Lotus team principal Eric Boullier’s prediction that his team will not be the only outfit to miss the opening F1 preseason test at Jerez which starts on 28 January.

Yes i´d say that´s a spelling error. My brain still thinks it´s 2013 sometimes so i can understand them :)

Its not old news. Dont know why they incist on calling it the MP4-28. Its not just a typo its called the 28 through the whole article.

I think they made a mistake writting car's name. News was written today.

Omnicorse also has written about it.

Anyways its sad news. I wonder if they need to redesign or just change the strength of some materials.

Maybe they have a weight issue, if they strengthen the chassis it would mean extra kilo's. Maybe they have already hit the 690KG minimum weight limit. Weight was never a problem in the V8 era but the new power-units are heavier. Or it could just be a design flaw that has nothing to do with weight but solely the strength of their chassis. Anyhow not good news for McLaren.
Even for the best teams, you're talking 12 weeks from pressing the button on a chassis build to having a completed chassis.The first test is in early February, you want to be building the car up during January. So you have to be starting to build your chassis and gearbox in the middle of September.
So you're working forwards and backwards at the same time - backwards from the first test and forwards from the initial proposals for the car.
Once a team has built a new chassis, the team have to do all the crash tests before they can go testing.

Until I read this ''bad'' news on Mp4-29 falling the crash test on Autosport, ESPN F1, BCC Sports, SkyF1 or other more relevant sites I'm not buying it.....

I'm not saying that GPToday is a unreliable web site....but still.....

We've heard about other teams (and McLaren, too, if I recall) not passing initial crash tests and its never seemed to hurt anyone. Puts production behind, of course. Worse would be if the FIA nixed the nose design for some reason, as that would have aero repercussions down the entire body. That was omnicourse's rumor about Lotus last week, I think.

I don't remember people citing omnicourse in past seasons, but this year they seem to be everywhere. I've quoted a few of their articles myself.
