标题: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.
在银石站大家对于红牛升级的关注都围绕在引擎外壳部分，像是有个侧箱上类似护罩类的

红牛升级前后对照图
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.
然而其中一个没被注意到的改变是关于rb18的底盘
这项新设计并没有出现在在赛前的FIA改变通知中，因为这项设计并没有让红牛需要制造
全新的部件
这项设计让底盘变得更容易拆卸组装，今年许多队伍也有沿用
车队要更换底盘特定部分时就不需要太多的琐碎功夫
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.
新底盘一开始只有让MAX在礼拜五的练习中试用,PEREZ仍用上一版的
红牛习惯在正式把更动应用在两台赛车之前，用这样蒐集连续资料的方式来衡量升级的

这站升级过的RB18底盘特写
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.
红牛的这项新更动将让他们扭转跟法拉利竞争的局势
法拉利在赛季初采用了一种叫作Ice Skate的技术
ice skate是指底盘下方外侧的底盘侧翼，然而法拉利将其作了更多改良，而这项改良就是这次被
红牛这次在银时站拿来采用当作升级的东西
这项改良包括在后轮前方的罩子挖空一部分，这个改动不仅改变了底盘两处的几何学设计
， 也曝露了跟底盘侧翼连接的舌型翼
我们可以从以下的红牛旧版底盘跟法家的改良版底盘看出对照

补充心得:
这篇原作者限于篇幅，所以只写比较新的更动
简单讲
ice skate最早是红牛先研发出来的技术
是一片坐落在底盘后方外侧角落，有多个气孔的金属薄片，作用类似底盘延伸出的小尾翼
下图白色箭头处即为RB18底盘的ice skate
https://i.imgur.com/V0vqIqf.jpg
ice skate最大的作用之一就是可以避免豚跳太早发生、大幅提升涡流扩散效率
它的气孔在空气动力学的角度上也有很大的助益
那后来法家也采用了ice skate，并且为了因应ice skate而在车身改良两个部分
1. 底盘罩挖洞 2. 加装一根舌型翼在ice skate 外部
然后红牛在银石站把法家的这两项改动直接拿来试用
只能说法牛不只场上拚搏,双方在车身设计的任何一个部分也都是在互相模仿改进的
