紅牛在銀石站的隱密升級 - 一級方程式賽車 Formula One

標題:The hidden F1 upgrade Red Bull snuck under the radar at the British GP


All of the attention on Red Bull’s upgrades at Formula 1’s British Grand
Prix has revolved around the engine cover bodywork that includes what looks
like a shelf above the sidepods.


在銀石站大家對於紅牛升級的關注都圍繞在引擎外殼部分，像是有個側箱上類似護罩類的
設計

However, something that’s slipped under the radar but has now been spotted
is an intriguing change the team has made to the RB18’s floor.

The new design did not appear on the pre-event FIA notification of changes as
it had not required the team to manufacture an entirely new assembly.

Instead, it takes advantage of the patchwork quilt-like qualities of the
floor designs we’re seeing from teams this year, whereby sections of the
floor can be exchanged with one another without too much fuss.




然而其中一個沒被注意到的改變是關於rb18的底盤

這項新設計並沒有出現在在賽前的FIA改變通知中，因為這項設計並沒有讓紅牛需要製造
全新的部件

這項設計讓底盤變得更容易拆卸組裝，今年許多隊伍也有沿用

車隊要更換底盤特定部分時就不需要太多的瑣碎功夫




The development was initially only run by Max Verstappen during Friday’s
interrupted running, with teammate Sergio Perez sticking to the previous
version.

This is in keeping with Red Bull’s approach, as it likes to gather
back-to-back data on upgrades, before applying them to both cars.

This practice ensures that it can check there is good correlation between the
team’s simulation tools and the real world environment before it commits to
them for the rest of the race weekend.




新底盤一開始只有讓MAX在禮拜五的練習中試用,PEREZ仍用上一版的

紅牛習慣在正式把更動應用在兩台賽車之前，用這樣蒐集連續資料的方式來衡量升級的
效果

這站升級過的RB18底盤特寫



The new design turns the tables on Ferrari, which adopted what has become
known as the ‘ice skate’ solution earlier in the season.

The ice skate, which incorporates the edge wing on the underside of the car,
rather on the upper surface, was combined with further design features on the
F1-75, for which Red Bull has now applied a similar logic.

This results in a floor cut-out ahead of the rear tyre spat region, which not
only facilitates a change in the geometry of the two floor sections, but also
exposes a tongue-like wing that’s connected to the skate.

We can see the old specification of floor on the Red Bull and the solution
used by Ferrari for comparison, below.


紅牛的這項新更動將讓他們扭轉跟法拉利競爭的局勢

法拉利在賽季初採用了一種叫作Ice Skate的技術
ice skate是指底盤下方外側的底盤側翼，然而法拉利將其作了更多改良，而這項改良就是這次被
紅牛這次在銀時站拿來採用當作升級的東西

這項改良包括在後輪前方的罩子挖空一部分，這個改動不僅改變了底盤兩處的幾何學設計
， 也曝露了跟底盤側翼連接的舌型翼

我們可以從以下的紅牛舊版底盤跟法家的改良版底盤看出對照

補充心得:

這篇原作者限於篇幅，所以只寫比較新的更動

簡單講
ice skate最早是紅牛先研發出來的技術
是一片坐落在底盤後方外側角落，有多個氣孔的金屬薄片，作用類似底盤延伸出的小尾翼

下圖白色箭頭處即為RB18底盤的ice skate

ice skate最大的作用之一就是可以避免豚跳太早發生、大幅提升渦流擴散效率

它的氣孔在空氣動力學的角度上也有很大的助益


那後來法家也採用了ice skate，並且為了因應ice skate而在車身改良兩個部分
1. 底盤罩挖洞 2. 加裝一根舌型翼在ice skate 外部


然後紅牛在銀石站把法家的這兩項改動直接拿來試用



只能說法牛不只場上拚搏,雙方在車身設計的任何一個部分也都是在互相模仿改進的
