although held only a week after the Chinese Grand Prix, the of Bahrain has brought us a number of novelties in the cars. We are going to review some of them, starting with those that have a direct relationship with the characteristics of the third Grand Prix of the season. And is that the heat has forced teams to adopt different solutions to combat temperatures close to 50 degrees on the asphalt.
The first modification that we’re going to see is that Mercedes has implemented in its shark fin. This flap has gained thickness to create an opening in the top and so to extract the heat that is given off of the engine, the hybrid system and in general all the internal elements of the car in that area. As a side effect, the double-edged sword of this design adds stiffness extra the flap. This modification has already proved in the pre-season test held in Barcelona and, without a doubt, it is the choice of Mercedes for the Great Prizes that the temperature is higher than normal.
Another of the modifications usual in such cases is that of the oversized the final area of the bonnet, that wins surface to extract the heat better. To illustrate this case we have chosen the comparison between China and Bahrain in the bonnet of the Renault, but it is a modification required on all computers. The red point corresponds to the position of the exhaust of the car that serves us as a reference to appreciate the differences. The body not only is separated from said exhaust, but that win volume on the sides for better heat removal.
Continuing with modifications directly related to the performance, we started with one of the new most striking of this Grand Prix. Ferrari has released this weekend a front spoiler profoundly remodeled and has five major developments.
The first is the incorporation of an additional division in the main layout (1). This type of modification allows for increased levels of downforce, but on the other hand complicates the treatment of the aerodynamic flow -make it more difficult to control – so it is important to make sure that it works correctly or the car will gain instability in your behavior.
on the other hand there have been changes in the sizes of various elements such as the waterfall of flaps close to the endplate (2) -marked in orange – or the end of the plane main (3) marked in yellow. It has also changed the shape of the curvature (5) marked in red and, finally, the beginning of the flap secondary end (4), marked in white.
As always commented, the front wing is the key element for achieving the concept’s streamlined global car to work, since it is the first element that enters in contact with the air and, in addition to fulfill its function of generating downforce, you must distribute the air to the rest of elements present in the car, even to influence the effectiveness of the rear part of the car.
We went to Force India to observe the area in the vicinity of the cockpit. In it we can appreciate a new bargeboard that has won quite a few incisions made in the upper part (7). The previous one had four and premiered in Bahrain features a total of ten cuts. In addition, the plaque that accompanies it has gained in length (6), occupying almost the entire string of this element.
As a complement to this amendment, the VJM10 has also changed the diverter of flow associated with the pontoon. In the horizontal part has lost length to stay in the middle, while in the bottom has seen added a new element of slitting in the direction of the rear.
Haas has also taken him to Bahrain, a new front wing, although in this case not as modified as the one we’ve seen previously in a Ferrari. The american team has split the last flap secondary (9) with the same aim as that of Maranello: to generate more downforce at the expense of running the risk of losing control over the stability of the aerodynamic flow. In parallel, the design of the metal parts (8) that provide rigidity to the assembly have also been modified.
we Finished the review of the technical developments of the Bahrain Grand Prix with a further sample of the continuing evolution of Sauber. The team based at Hinwil introduces small changes in each of the Grand Prize and, on this occasion, has launched a new support of the mirrors (9), something below with respect to the previous version used in China.
These are the highlights of the last Grand Prix that gives way to the european season in which, surely, we will see even more new features to be found the headquarters of the teams much closer to the circuits that will compete in the upcoming races.
