BRIEF DESCRIPTION OF HOW THE UPGRADE WORKS

1

Floor Wing

Performance – Balance Range

A new flap has been designed with locally longer chord profiles more camber angles and increased angles of incidence.

More front wing had generated on all the profiles as a consequence of the new design of the flap profiles.

2

Rear Body

Performance – Flow Conditioning

Surfaces raised locally from previous geometry at the sister improves the total pressure on the upper surface floor to topbody split time to form a blister

For a given load the downstream conditioning of the blister improves the total pressure on the upper surface of the floor.

GEOMETRIC DIFFERENCES COMPARED TO PREVIOUS VERSION

BRIEF DESCRIPTION OF HOW THE UPGRADE WORKS

1

Front Wing Endplate

Performance – Flow Conditioning

Change in endplate camber.

This change in endplate camber, which curves gently inboard, is designed to improve flow on to the front cake tin deflector, and hence flow to the rear of the car.

2

Floor Edge

Performance – Flow Conditioning

Slot added to outer edge of floor.

This is a detail change similar to that found on other cars, and it is designed to improve floor performance when it is running close to the ground.

3

Rear Corner

Performance – Flow Conditioning

New lower deflector endplate.

This modification generates increased local load on the lower deflector inside the rear wheels, which in turn increases overall diffuser load.

4

Floor Body

Performance – Local Load

New bib vane added to keel.

The new bib vane has a dual function and benefit first, it generates local load in the middle of the car, second, it sends a vortex under the main floor of the car.

BRIEF DESCRIPTION OF HOW THE UPGRADE WORKS

1

Front Wing

Circuit Specific – Balance Range

Revised flap widespan.

A new front wing flap which allows a larger aero balance range. This includes different options of gurney flap ' to match aero balance requirements.

2

Front Suspensión

Performance – Flow Conditioning

Revised fairing on front suspension legs.

The front suspension fairings have been locally modified to integrate with a revised front brake duct inboard face and inlet geometry.

3

Front Corner

Performance – Local Load

A fully revised front corner internals and scoop.

The new design of the front brake duct shape improves aerodynamic efficiency , and the revised internal ducting improves the brake cooling efficiency

4

Floor Body

Performance – Local Load

Revised floor fences, floor overall shape and floor edge.

A new floor has been developed and brought to this event as part of an aerodynamic update that also includes a revised sidepod, increasing overall car downforce.

5

Coke/Engine Cover

Performance – Local Load

Revised sidepod shape and width.

A new sidepod has been developed and brought to this event as part of an aerodynamic update that also includes a revised floor, increasing overall car downforce.

6

Cooling Louvres

Circuit Specific – Cooling Range

New louvres to suit new sidepods.

A revised set of louvres will be introduced to suit the new sidepods and cope with the high ambient temperatures expected in Barcelona.

7

Rear Wing

Circuit Specific – Drag Range

Revised upper rear wing assembly, mainplane, flap and RWEP.

A new rear wing has been brought to this event, aimed at improving lap time at high downforce circuits like Barcelona and Monaco.

8

Rear Corner

Performance – Local Load

Revised RBD lower wing endplate.

A previously raced rear brake duct lower winglet geometry incidence angle which is better suited to the new floor geometry.

9

Sidepod Inlet

Reliability

Removed cockpit strake.

A strake on the cockpit has been removed. This is aimed at improving the visibility the drivers have towards the inside corner, in particular.

10

Diffuser

Performance – Flow Conditioning

Centre diffuser packer.

This is a test option geometry for the new floor to study alternative flow conditions around the central diffuser area.

UPDATED COMPONENT

PRIMARY REASON FOR UPDATE

GEOMETRIC DIFFERENCES COMPARED TO PREVIOUS VERSION

BRIEF DESCRIPTION OF HOW THE UPGRADE WORKS

1

Floor Body

Performance – Local Load

Fundamental changes are largely to suit surrounding geometry but the surfaces are smoother along the length of the car.

The mainfloor body modifications are to better manage airflow along the lower surface of the floor in combination with the surrounding geometry.

2

Floor Fences

Performance – Local Load

Twin OB fences with remaining two fences repositioned, reprofiled and extended forwards.

Fences rearranged to modify the airflow around the forward floor and provide more consistent load throughout the ride height range.

3

Floor Edge

Performance – Local Load

Floor edge wing has moved rearwards, with an associated change to the planview edge of the floor, and the shape in front of the rear tyre.

Modifications are intended to modify the loading distribution along the edge of the floor and consequently the performance through the operating envelope of the car.

4

Sidepod Inlet

Performance – Flow Conditioning

Sidepod inlet has moved rearwards compared to the previous version with the lower edge raised to create a shallower inlet.

Inlet moved rearwards to better influence the surrounding airflow whilst retaining the requirements of the cooling package.

5

Coke/Engine Cover

Performance – Local Load

Bodywork changes are to create an upper surface that slopes down to the rear of the car, with the maximum width of the bodywork pushed rearwards also. The xit at the rear of the bodywork is larger and higher.

Revised shapes improve airflow delivery to the rear of the car and re - distribute the internal cooling flow exit to a more optimum position.

6

Cooling Louvres

Circuit specific – Cooling Range

Two options of bodywork cooling louvres will be available to suit the new bodywork shape, with blanking panels for each to give fine adjustments.

As always the bodywork louvre exits will be as closed as possible for optimum external aero performance, to maximize the quality of the flow at the back of the car.
