Inspire1碳管规则花纹和不规则花纹的区别

教程 SBDJI 3549浏览 0评论  赞 0

早期对于Inspire1出货,碳管存在规则花纹和不规则花纹的区别。
有些模友甚至认为,大疆创新厚此薄彼,国内拿到的就是规则花纹的测试版,国外则是不规则花纹的正式版区别,其实则不然。
国外和国内在早期可能订购到A版规则花纹碳管,后期则A版彻底消失,国内、国外都是B版不规则花纹碳管了。

碳管为不规则花纹

官方对于悟的碳管版本,则说明货箱标签A为规则花纹,B为不规则花纹的区别,性能上并无二至。


rcgroups上也有对于碳管版本的讨论:
I could give some input here.
The classical CF tube is made of prepreg. The inner part is made of undirectional prepreg and the surface is a layer of 3K woven prepreg.
The other CF tube with larger patterns is made from a completely different process, which is filament winding. You could consider a winding tube is made of semi-woven CF completely, from the bottom to the surface. Compare to prepreg tubes, winding tubes shows much better torsion strength but is more difficult to manufacture, it heavily relies on expensive automation equipments. On the other hand the tooling to make prepreg tubes is very simple and cheap.
Both prepreg tube and filament winding tube meets the standard of inspire 1 so they will not bring in any noticable performance difference. As a matter of fact two tubes cost almost the same. DJI chooses to use them both simply to secure the supply chain.

”常见的整齐花纹碳纤维管是预浸料做的。内部铺层为单轴方向,外部铺层为3k碳纤维预浸布。 而另外一种更大花纹的碳管使用完全不同的工艺—碳纤维缠绕工艺,可以理解为整体纯碳纤维卷绕管。跟普通碳管比呢,缠绕碳管有高得多的扭转强度但生产起来更加困难,它十分依赖昂贵的自动化机器设备。对比来说,制作3k管使用的工具设备简单而廉价。 这两种工艺均满足 Inspire 1的设计使用要求,所示不会带来任何使用上的差别。
实际上两种碳管成本几乎一样。之所以两种都用,是为了满足供应链而已。— Turbo博士“

由此可以猜想,大疆创新应该是早期选择了规则花纹碳管,但发现,变形机构使碳管受力巨大,变形过程中震动增加,在后期全部更换为强度更高的不规则花纹碳管。
早期标配的正反螺纹桨,在后期也已更换为快装版本,避免射桨问题。
