加里·安德森解析法拉利赞德沃特升级的细节门道
法拉利在赞德沃特带来的升级看似不起眼，但加里·安德森认为，这些细节上的优化作为整体分析可能会带来性能回报。
在一级方程式中，一切都在于细节。
法拉利在赞德沃特的升级件——从冲刺排位赛起才装上，很可能是因为法拉利备件不多，不想在练习赛中冒损坏的风险——看起来也许不起眼，但我们谈论的正是这些更细微的细节，它们能优化整体性能。实际上，这些改动成本很低，因此在至关重要的预算上限方面不会破坏预算。
这个位于导流板安装系统上的小细节改动（以青色标出）起到了为底板气流做准备的装置的作用。所以尽管它看起来不起眼，却很可能对底板的性能和一致性产生相当可观的影响。
外侧垂直转向翼片高度的降低（以绿色标出）再次使得底板前缘翼板下段（以紫色标出）对该处气流走向有更大的影响。
这应该能让下方横向导流板产生更强的效果，从而在赛车底板两侧形成更强的封严系统。
底板前缘分流器的布置位置将能最大程度优化来自重新调整位置过的导流板安装座（用橙色箭头标出）的气流。
横跨这些分流器的横向转向导流板也将与修改后的导流板安装座协同工作，优化流向底板前缘下表面的气流。
扩散器尾缘上的这个细节，是提升车底气流一致性的另一种手段。
利用增大横梁翼（梁翼）中央部分弦长（绿色高亮显示）的做法，将提升扩散器中央部分的性能。
把垂直后缘扰流条（青色高亮显示）较大的中央部分向外侧移动，将改善垂直壁与顶部相接的外侧部分的一致性。这个过渡区域历来容易出现气流分离问题。
总体而言，这些研发更侧重于空气动力的一致性，而非一味追求下压力。正是这种一致性让车手建立信心，使他们能够更深入地挖掘自己的天赋，而不必担心突然出现的意外甩尾，尤其是在入弯时。
另外我还发现了一点。所有车队都会尽最大努力监控前轮和后轮的轮胎温度；这对排位赛中那独一无二的单圈至关重要，因为前轮温度的提升总是很困难。
你可以从上面这两张图片中看到，法拉利一直在调整红外摄像头的位置（橙色椭圆），以获得最佳读数。
旧图片中没有摄像头；新图片中摄像头位于端板底部，而另一种方案如下图所示，安装在外侧端板表面上。
这里将是空气动力学妥协最小化的最佳位置，因为它不会影响安装在端板底部的导流叶片所产生的气流外排效应。

It’s all about the details in Formula 1.
Ferrari’s Zandvoort upgrade - bolted on from sprint qualifying onwards, likely because Ferrari doesn't have many spares and didn't want to risk damage in practice - might not look like much, but it is the finer details that we are talking about that optimise the overall performance. In effect, they cost very little, so they don’t break the budget as far as the all-important cost cap is concerned.
This small detail change in the bargeboard mounting system (highlighted in cyan) acts as a flow preparation device for the underfloor. So even though it doesn’t look like much, it could very well have a reasonable effect on the performance and consistency of the underfloor.
The reduction in height of the outer vertical turning vane (highlighted in green) again allows the lower section of the foot plate (highlighted in purple) to have more influence over the direction the flow is going to take at that point.
This should allow the lower horizontal vane to be more powerful, which should create a more powerful sealing system along the sides of the floor.
The positioning of the floor leading edge splitters will best optimise the flow coming off that repositioned bargeboard mounting (highlighted with the orange arrow).
The horizontal turning vane running across those splitters will also work in conjunction with that modified bargeboard mounting, optimising the airflow to the undersurface of the floor's leading edge.
This detail on the trailing edge of the diffuser is another way to help with the consistency of the underfloor.
Using the increase in the chord length of the beam wing (highlighted in green) in that central section will improve the performance of the central section of the diffuser.
Moving the larger central section of the vertical trailing edge trip (highlighted in cyan) outboard will improve the consistency of that outer section where the vertical wall meets the top section. This transition is always susceptible to separation problems.
Overall, these developments are more about aerodynamic consistency as opposed to out-and-out downforce. Consistency is what gives the driver confidence, allowing them to dig deeper into their talent without getting bitten by sudden unexpected snaps, especially on corner entry.
Just one additional thing I've spotted. All the teams do their best to monitor the front and rear tyre temperatures; this is critical to that one-off lap in qualifying, as it’s always difficult to get front tyre temperatures.
You can see in these two pictures above that Ferrari has been playing around with the infrared camera position (orange ellipse) to get the best reading.
The old picture has no camera; the new one is on the endplate foot, and the alternative is pictured below on the outer endplate surface.
This will be the best place for the least aerodynamic compromise, as it won’t influence the outwash generated by the turning vanes mounted on the endplate foot.
