Povratak ajkulinog peraja me je postakao da tragam za ranijim izdanjima i na koncu sam sproveo istraživanje. 46 bolida su tokom istorije u jednom momentu imala ovo rešenje.

Ovo bi se moglo nazvati ekstremnim primerom ajkulinog peraja (u pitanju je Granpri bolid-jednosed, da ne bude zabune!), a ovaj zanimljiv eksperiment nije dao zeljeni rezultat jer iako je ovakav bolid bio vrlo aerodinamican ogromne bocne povrsine su bile preosetljive na udare vetra sto je izazivalo probleme sa upravljivoscu. Nakon samo par pojavljivanja u ovakvo ruhu bolid je konvertovan ponovo u konvencionalnu konfiguraciju.

Odlican vebinar o aerodinamici u Formuli 1

 

Edit, na mobilnom ne mogu kvalitetno embedovati video.

Halo shelved as Formula 1 picks 'shield' for 2018 cockpit device

Formula 1 is set to ditch the halo cockpit protection system and prioritise the newly-introduced 'shield' concept for 2018.

The decision was taken in Tuesday's Strategy Group and F1 Commission meeting in Paris.

The halo had originally been on course for introduction this season before being postponed for further testing and an intended 2018 debut following a previous unanimous Strategy Group vote.

But the device, which teams trialled during practice sessions last year, had divided opinion.

During the Chinese Grand Prix weekend earlier this month, the alternative shield concept - a see-through screen that would not cover all of the cockpit - was presented by the FIA during the Friday drivers' briefing.

It has now emerged as the favoured choice, with the FIA stating: "A number of more integrated solutions for additional frontal protection have been studied, and the decision has been taken to give priority to the transparent 'shield' family of systems.

"The FIA aims to carry out track tests of this system during this season in preparation for implementation in 2018."

Touted as a better compromise between safety and aesthetics than the halo or Red Bull's proposed aeroscreen concept, the shield drew mixed reviews when shown to drivers.

Daniil Kvyat, Kevin Magnussen and Romain Grosjean were among the sceptics about both the shield and the general need for cockpit protection, while Felipe Massa urged critics to prioritise safety over aesthetics.

Zapravo Formula E će sledeće godine preteći Formulu 1 u revoluciji zaštite glave vozača i sad FIA pokušava navrat nanos uspostaviti spomenutu zaštitu u F1 pre FE. Što bi moglo da se pokaže kao katastrofalna stvar jer za neke stvari treba vremena. Formula E jako ljuti Formulu 1 jer s zbrzanim formatom trkačkog vikneda mogu raditi i implementirati stvari puno brže od F1. Na primer, staklo nove zaštite vozača se neće tako brzo uprljati na FE bolidu u odnosu na F1 jer su sesije kraće i sl. također Bernijev san o Londonu, Nju Jorku, Parizu, Hong Kongu pa i neki drugi kao trka u Africi je uzeo Agag. Komično Agag je napravio eTrku od milion dolara u Las Vegasu, ono što je Berni sanjao da uradi s F1 ali u stvarnom svetu, ko da je Agag to uradio s rešenicom "it's something". Mada je ovo samo moje skromno mišljenje i mislim da se F1 ne trka s FE..

Shield tests in Monza and Singapore

The Formula 1 commission has halted the halo. At the same time, the FIA ​​announced that it would extensively test the "Shield" replacement solution in order to deploy it in 2018. Crucial is the judgment of the drivers.

The halo is dead, long live the shield. This is the same way to describe the recent decision of the Formula 1 Commission. Halo, known as "Halo" around the cockpit, was not approved by the teams and half of the drivers. Just as not the Red Bull shield presented a year ago in Sochi.
The FIA, under the direction of Laurent Meckies, has been working on a replacement solution for quite some time. It is a one-meter-long protective PVC shield integrated into the chassis. It should be able to defend flying objects from a maximum of one kilogram up to 225 km / h from the car and thus the driver. The project internally operates under the name "Shield" at the FIA.
The shield is visually the most beautiful solution
Until now, the protection screen was only presented to the teams and the drivers. Auto motor and sport has seen the sketches of the Shield. Of all solutions used so far, it is by far the most elegant. The disc, which is curved in the middle, begins where the nose passes into the chassis and runs in a line just above the chassis, behind the front cockpit edge. The sides of the disc are flush with the neck guard.
Before the shield regulation, it has to be tested in four stages. The first consists of computer simulations, followed by an accident in the laboratory . The disk is bombarded with a ball at the appropriate speed to see if it is holding. The third step takes place in the boxing race. The FIA ​​wants to check whether the drivers are disabled when entering and exiting.
The last part of the test series is the decisive one. The drivers will try the Shield in two Friday sessions to find out if the visibility is impaired. There are already concerns that the windscreen starts in the rain and turns the already already poor visibility into a total blind flight. If the timetable is observed, the driving tests will happen in Monza and Singapore.
Pilots not yet excited
The driver's judgment depends on whether the Shield is introduced in 2018. So far, the pilots are still cautious. "The Shield certainly looks better than the Halo - at least as far as the visual impression is concerned, but we have to try out on the track how it feels in the car," said Valtteri Bottas.
Daniel Ricciardo also commented on the decision of the FIA: "The first impression is okay, but now we have to start with the development, only then can we say more."
