Technically Formula 1 - Chinese Gran Prix

Technical innovation is what makes Formula 1 so different from any other form of racing. The on track action is as much played out by the engineers and aerodynamicists as it is the drivers. We are here to admire, study, and discuss this beauty that exists on the ragged edge of what we think is possible, or at least what we thought was possible.

For more technical intrigue, be sure to check out the Bahrain Pre-Season test and the previous Gran Prix.

This post will be updated as the weekend progresses. Discussions and questions are welcomed and encouraged in the comments section below.

RB10 front wing detail. This is the section of the wing that creates the Y25o vortex, which can be seen this weekend due to the colder temperatures and relatively high humidity.

RB10 bulkhead detail. Because the chassis is a single piece to enhance its strength, the designers have to incorporate access holes. Two of these holes can be seen on the top to give access to working on the suspension.

RB10 brake duct detail. You can also make out Red Bull's carbon S-duct that rests just in front of the bulkhead.

The starter hole can be seen sticking up through the floor at the leading edge of the diffuser (annotated).

Mercedes have brought a new nose to Shanghai that allows more air to flow underneath.

F14T blown wheel nut.

Technically Formula 1 - Chinese Gran Prix

Ferrari have been running ductless front brake ducts for the first three races, but since introducing a blown wheel nut they have had to create a duct (seen on the left of the brake assembly) to funnel this air.

Technically Formula 1 - Chinese Gran Prix

There is a strange carbon "garden hose" type of structure inside the F14T's blown wheel nut, perhaps to direct the outflow.

Technically Formula 1 - Chinese Gran Prix

Special wheel nut gun to accommodate the new blown wheel nut.

Lotus E22

Poor Maldonado...

Let me rephrase that: Rich Maldonado...

Technically Formula 1 - Chinese Gran Prix

E22 front wing sans the nose wing, at least for the moment.

I am assuming the wood and metal contraptions are for shipping purposes.

Technically Formula 1 - Chinese Gran Prix

What looks like a gurney flap on the outer 2/3 of the E22's front wing.

The MP4-29 with one wishbone wing. At the Bahrain 2-day test a week ago, McLaren were testing their chassis with 0, 1, and 2 wishbone wings (they've run 2 at every race in 2014, so far).

Force India have come to Shanghai with an interesting sidepod configuration.

Technically Formula 1 - Chinese Gran Prix

A closer view.

Technically Formula 1 - Chinese Gran Prix

For most teams, the main sidepod airflow conditioner (the vertical strake that changse the airflow near the sidepod's front inlet on the side) is mounted down by the floor, but the Force India chassis in Shanghai have brought an interesting setup where the vertical vane is attached to the middle of the sidepod.

Frontal view of the sidepod. I am eager to see this with the floor.

Force India are running a FRIC style suspension system in Shanghai this weekend. For a better understanding of what a FRIC suspension is, here is an article by the esteemed Craig Scarborough.

Toro Rosso STR9

Technically Formula 1 - Chinese Gran Prix

STR9 front wing detail.

Technically Formula 1 - Chinese Gran Prix

A rearward view of the STR9's front wing. The underside of a front wing is as much responsible for generating downforce as the the top side; where the top creates a high pressure zone that presses the wing down, the bottom creates a low pressure zone that pulls the front wing down.

Technically Formula 1 - Chinese Gran Prix

Toro Rosso have fitted new vortex generators on top of their sidepods for Shanghai.

Technically Formula 1 - Chinese Gran Prix

Inlet on the leading face of the SRT9's T-tray. Not certain where this leads, but it may have the benefit of reducing the air going underneath the chassis floor, thereby iincreasing downforce when the lower pressure air reaches the rear diffuser.

This could either be for cooling the sidepod area, or for conditioning air entering air through the sidepod inlet; will update when I see the front view.

The most important side of the monkey seat in 2014 is the underside because it conditions the exhaust gasses to upwash, hence the top-side mounting.
