The biggest disadvantage of this technique is the complexity of building it. While building one layer of 6 fuel stacks connected to the central stack by asparagus is relatively easy, higher payloads will require more layers of fuel stacks and struts, and this overall makes the technique challenging and laggy(due to the high part count)

所有引擎都首先使用S4燃料箱的燃料,随后使用S3的 燃料,依此类推
芦笋节式分级的顶视图

芦笋节式分级是一种设计高效火箭的方法。

其主要思想是,设计一个并联许多发动机的火箭,这些发动机上方装有燃料箱。所有发动机同时点火,而这种设计的特点在于:发动机并不是各自消耗自己顶部的燃料箱,而是所有发动机一起从最外侧的两个燃料箱中获取燃料。当最外侧的两个燃料箱耗尽,它们连带着下面的两个发动机一起被分离。下一对燃料箱(它们的燃料还是全满的)将投入使用。这种火箭始终带着所需要的尽可能少的燃料箱飞行,并且一直可以使用所有它还携带者的发动机。

这个设计可以通过将燃料管按分级顺序依次连接燃料箱来做到。这个设计利用了发动机总是尝试从离它最远的燃料箱获取燃料的特点。

游戏附带的 "Kerbal X" 演示了这个技术。

目前的缺陷

这个技术的最大缺陷就是其设计的复杂程度。虽然制作一层连接到中间芯级的六油箱芦笋节相对来说比较容易,但对于更大更重的载荷,就需要更多层油箱(以及更多的加强筋)。这种设计将变得困难,并且由于零部件数量大幅增加,容易带来游戏帧率下降。


另一个缺陷是,这类火箭通常看起来不美观也不真实。其原因往往源于安装了许多SAS模块以及缺少鼻锥(因为原版KSP中安装鼻锥只会带来额外的重量和阻力)

这些缺陷可以通过安装一些火箭零部件MOD来解决。可以使用更大容量的燃料箱和更大的发动机。这样可以有效的减少零部件数量,提高稳定性,并且具有更好的外观。

这类火箭容易发生旋转,并最终可能导致失控。这些是你在尝试这种设计时需要记住的。

后续的缺陷

Asparagus staging benefits a lot from the inaccurate way KSP is modeling atmospheric drag in the current version (0.20.2). Currently, each part of a vessel generates drag proportional to its mass, regardless of how it is placed and how much of its surface area is exposed to the direction of the airflow (yes, that means all the Aerodynamic Nose Cones you put on your rockets just slowed them down even more). The developers have already announced that the aerodynamic model will be made more realistic in future versions, which will likely mean that the wide, flat designs of asparagus-staged crafts will generate a lot more atmospheric drag than slimmer designs with vertical staging.

The new atmospheric drag model is unlikely to make asparagus staging completely obsolete as there is a planned real-life rocket which uses this method with one stage [1], but it will likely make it a lot more challenging to create aerodynamic crafts which use this technique excessively.
