The Secrets of Alpine’s Unique Wave-Like F1 Front Wing Upgrade

by admin

The newly introduced design is a continuation of major modifications previously implemented by the team to the architecture of its front wing during the British Grand Prix. This serves to illustrate the vital role this upper flap redesign occupies in the hierarchy of downforce generation.

Clearly, what was unveiled at the Hungaroring is a choice meant to occupy a high position in its downforce selection range.

The changes made during the Silverstone update introduced a broader movable flap area for the top two flaps, facilitating the use of this innovative wave-shaped trailing edge.

The wing’s peak elements are outwardly inclined across the tyre, aiming to produce the necessary load while contributing to the team’s overall outwash targets.

Upon comparing the former (below) and the recently introduced (main photo, above) front wings, it is evident that there is an amplified emphasis on outwash generation, with a comprehensive revamp of the wing structure to accomplish this.

The chord length of the mainplane at the endplate end has been lengthened, while the chord length of the subsequent three flaps has been minimized.

This results in a tighter gap between each flap at the endplate junction, leading to each of the elements becoming more compactly coiled.

There have been adjustments to the diveplane as well, which remains an S-shaped variant but has been elevated to a superior position and reshaped to fit its new position.

The pod that accommodates the infrared tyre monitoring camera has also been relocated to a lower position requiring a more upward tilt, although this is probably more related to the aerodynamic characteristics it presents in this position than the perspective it offers.

Notable changes have also been implemented at the inboard end of the wing. The movable parts of the upper flap have been broadened, as the pivots have been relocated closer to the sides of the nose.

Subsequently, the non-movable part has been made narrower, altering the flaps’ shape as a result.

In a similar vein, the mainplane’s leading edge and the second flap have been reshaped to account for these alterations and provide the necessary aid for airflow around the wing and nose section.

It’s noteworthy that this isn’t the first instance where Alpine has introduced what may seem like an unusual trailing edge design, with a notched version utilized in its previous specification front wing layout.

Such design nuances may have encouraged the team to further develop along this line, even though both versions bring something slightly different to the table in terms of the downforce spectrum.

Frequently Asked Questions (FAQs) about Alpine F1 Front Wing Upgrade

What is the primary change in Alpine’s F1 front wing upgrade?

The primary change is a wave-like redesign of the upper flap, which plays a vital role in the hierarchy of downforce generation and facilitates a greater outwash effect.

What was the aim of the changes made at the Silverstone update?

The changes made at the Silverstone update introduced a broader movable flap area for the top two flaps, enabling the use of the new wave-shaped trailing edge.

How does the new design help in achieving the team’s overall outwash goals?

The peaks of the wing elements are outwardly inclined across the tyre. This design not only helps produce the necessary load but also contributes to the team’s overall outwash targets.

What are the adjustments made to the diveplane in the new front wing design?

In the new front wing design, the diveplane, while remaining an S-shaped variant, has been elevated to a higher position and reshaped to accommodate its new locale.

How has the inboard end of the wing been altered in the new design?

In the new design, the movable sections of the upper flap have been increased in width, with the pivots relocated closer to the nose’s sides. Consequently, the non-movable section has been narrowed, and the flaps’ shape has been altered.
