This article is about the New Lotus nose tested in Austin for the 2015 regulations. In the picture immediately below, is the figure showing our forecasted nose compared to the present nose of the English team. Here we are able to make a small comparison of our idea and see how instead the new regulations have lead to a different interpretation of the same areas. Using this comparison, we can figure out better what we can expect from the team next year.
As you can see, starting with 2 figures in the upper left and right, we have a frontal height that if reduced is creating a very high slope on the upper surface. This is the trends among their peers. As we rightly noted to think that must next year it will be convergent towards the tip or will reduce thickness bit by bit as it reaches the ends.
Looking at the smaller picture, it is understandable that we can provide on the car an effect of the pelican nose. This was discussed this year mostly in regards to RedBull. This possibly improved the downforce of the car, accelerating the air flow that passes in the lower part of the nose. The trends are similar between them for the two configurations shown, also if the differences are highlighted at the width of the nose at the ends. Clearly it cannot be wider than 140mm, it seems that at Lotus they have decided to remain very close to that threshold while in our design we see a thinning near the tip. If we put in the length of the regulations we notice that in fact there exists a requirement at the point that implies the creation of a section of area no larger than 9000 mm^2.
The secret lies in the way in which we choose the surface “A”: it can be wider but low or narrower and high (our hypothesis).
There would be probably this point of doubt:
If seems that at Lotus they have expected a wider configuration but it seems also that however they have not limited too much height so as to create a section much greater than 9000mm^2 (including therefore a pelican hump).
However, there is a small clause in the regulations that permits just a bit of freedom in this area of the nose: it is required in fact that the area is limited to areas include between the maximum point in height and a minimum point that is located 10cm below the first.
This means that if the area is measured is larger than 9000mm^2, but several parts of this are located below this lower limit, it will be accepted and then will be necessary for only the upper part of this level to be less than 9000mm^2. We can state that we could see the effect of the pelican nose or it becoming thicker just at the ends. Given that in reality, only a few portions of the section will actually be taken into account.
This for instance permits a larger adaptation of how we can notice on the RedBull at Monza and Spa-Francochamps where the addition of the pelican nose was more different between the two cases (next image).
This fact cannot be damage the section studied at point B in the regulations, it was originally requested to be a MINIMUM area of 20,000 mm^2. This implies that it can also be larger and more importantly that this remains below the height limited imposed in the regulations.
If you remember that actually we can state that the Lotus nose was created faster could be another qualitative proof and that probably was not a final product. It could be visible in the future with larger uniformity with respect to the profile suggested by us.
