OK, So i’ll admit I’m not really the April Fools type. I sat thinking about all of the incredibly evil things I could have posted as an April Fools prank and realized… I just couldn’t do it. So instead, I’m gonna post about a fictional weapon that Ive always thought was very cool looking, but entirely impractical:
This weapon was one of the cool weapons wielded by the race of Predators in the Predator series of movies. This particular shuriken was prominently featured on the AvP (Alien vs Predator) and AVP2 movies. Now the one featured here is a non-functioning reproduction shuriken, primarily because, well, this weapon would be near impossible to make work in real life, for reasons I’ll get into shortly.
I truly love many of the design details of this weapon. But what makes it such an intriguing weapon to me is primarily the subtle physical impossibility and impracticality of it. It is a weapon that appears, on the surface, to be physically plausible, but upon closer inspection, reveals aspects that are implausible, but so tempting close to real, that you cannot help but wonder if it would be possible to duplicate in real life.
For example, looking at the pic above, you may notice that the overall design of this shuriken vaguely follows that of the Japanese Fuuma (or Windmill) shuriken, but departs from traditional shuriken design in it’s asymmetry. The blades are all biased towards one side of the weapon. Now besides the fact this this offends my sense of symmetry, this massive weight imbalance would also make it a very impractical throwing weapon. And yet, in the movie, it is thrown just as a Fuuma shuriken would be, without exhibiting any of the idiosyncratic flight characteristics that one might expect from such a poorly balanced weapon.
An even more implausible feature of the weapon is the great disparity between the retracted form factor and the fully deployed form of the shuriken. Below is a picture of the center section of the weapon with the blades extended:
And here is a picture of the blades, again fully extended:
In the movie, the blades are shown to extend out of the center section of the weapon. From the pics, it is apparent that a considerable level of nesting can and would need to occur in order for this to be physically feasible. By my count, there are six blades, each blade consisting of 4 sections, an extension/pivot lever, an outer extension sleeve, an inner extension sleeve and the blade proper. The weapons deployment sequence is shown in the clip below:
AvP Shuriken – Deployment
Sweeeet…! Incidentally, the little clip above may also explain the weapons asymmetrical design. If the blades were to extend in a symmetrical fashion around the circumference of the weapon, there would be no safe place to hold it during deployment without risking the loss of a few digits. If memory serves, I think these were used primarily as throwing weapons, so if I were designing it, it would be perfectly symmetrical, and would open in mid air when thrown, so as to avoid the awkward asymmetrical design. The asymmetry seems like a pointless trade-off if you ask me, but then again, I’m not an alien weapons designer…
Anyway, during retraction, the blade would have to retract into the inner sleeve, the inner sleeve into the outer sleeve, and the whole outer sleeve assembly pivot onto the extension arm, which would then all fold neatly into the center section, completely occupying that space. Sounds good in theory, except that, given the physical dimensions of blades, sleeves, etc, there should be hardly enough room for all six blades, let alone a deployment / retraction mechanism…
Of course, given the advanced nature of Predator technology, these technical details would almost certainly only be limitations of human technology, and would be little more than niggling little technicalities to a predator engineer.
In the end, however, it is the overall aesthetic of the blades, and the deployment mechanism that makes this weapon so captivating, and while the technical challenges would be great, the design is ultimately so close to something that could be made using current technologies, it would be very tempting to try…
I wonder if DARPA would be willing to give me a research grant for this kind of stuff… 🙂
