楼主把本来的车壳负压区填了,理论上下压力会比不装还小

不一定原先负压区不规则 气流会乱,具体效果没试出来下次对比再试试

还是有点用,车尾稳点没那么灵

哇大佬你这个好看啊,其实后面试了下 没感觉出来啥提升 但是重量加了30多g

不是封闭底板,扩散器没用
我们模型的非封闭式底板,车壳后开口就是负压区,不加扩散器效果一样的
加扩散器还更重了不好

非封闭地盘,你下面加扩散器,实际上相当于把前面吸进来的空气压缩在了车壳尾部(扩散器上方的车壳内),形成的减速伞结构,实际上形成了高压区
封闭式地盘,前面吸进去的气流才能通过扩散器加速排出,在地盘形成负压区
真想要增加下压力,学铲车,把整个屁股竖直部分剪掉,让车壳前面吸进去的空气最大化从后部排出,形成的负压最大

我这个是中置电机,加这个感觉又回到了电机靠后的效果,车壳尾部原本是封闭的,跑快了飘,车子感觉不吸地,后面把车尾掏空跑着感觉吸地多了,但是布局的原因,车尾很灵活,感觉后轮抓地不够,有点控不住,后面还空就弄了个扰流,好跑很多,扰流板是模仿原车的

这个有兴趣,但是否太高?
