Gute Arbeit Danke

[@cogoid]

Good analysis! The gearbox looks like it contains a worm drive inside in addition to the gears that we see. It would have been interesting to see on the oscilloscope the mechanical bandwidth of the entire device -- how fast it accelerates and moves in response to a step input. 2:20 While the missile is in the launch tube, the wings are folded against the body of the missile. Once the missile is out, a pair of pyrotechnic pushers kick the wings open, and after that the wings stay in the unfolded position shown here. (There is a latch inside.)

[@tHaH4x0r]

I was wondering why it was able to hinge around the missile axis! Thanks for that input, makes a lot of sense.

[@rob-muntron]

Was wondering how the fin folding arrangement worked, thanks!

[@markhahn0]

Yes, that's what surprises me about the servo mechanism: it seems like it would be slower than some kind of direct drive, and with backlash, and mechanical/maintenance complexity. But perhaps I'm underestimating the operating regime: the vane is surprisingly strong/heavy and appears to be designed for significant deflection. It's also interesting to think about the engineering mindset for a one-way device. Yes, you want it to work, and yes you want to be able to store and ship the device, but in some sense, efficient engineering should incorporate the fact that it'll be used exactly once...

It's amazing that stepper motors have the torque and speed to achieve this - It hit home to me how damn fast these things actually go when he pointed out the paint and metal was discolored from aerodynamic heating.. brief research suggests about Mach 4 - faster than a rifle bullet :O for those trying to visualize what the vane's actually actually steering, they weigh around 1000kg and range of 150km, so it would have a flight time of about 2 minutes to steer it onto a target.

This unit uses a conventional DC motor.

[@markhahn0]

well, wikipedia says 120 km and 250 kg. and it's relatively recent (service since about 2020).

The first part of the vane is forward from the pivot. This is calculated so the force needed to move it is minimized. If you put too much forward it become instable (positive feedback) We do the same things with the rudders on boats.

Thank you very much for your explanations. any idea about the "crazy" routing?

[@cogoid]

Whoever designed the circuit itself was obviously reasonably competent, if old-fashioned. They probably built it on a bread-board, and debugged everything to make sure it performed according to the requirements of the contract. Once that was done, they gave the circuit diagram to a technician, to do the layout and the mechanical design of the board. That person was probably not very experienced, so they just used automatic placement and routing features of whatever bootleg EDA software they had. And that's it. The result worked, and nobody who was competent to review it bothered to do so.

[@TheRadeonVideo]

Stupid question. How does the system avoid excessive Gs? The reason I’m asking is because that leading edge counterweight is far larger than necessary to balance the fin or act as inertial dampening. Older aircraft like the F-4 phantom have counterweights in the controls to increase load forces during high G maneuvers, to avoid turning too hard. If the electronics don’t have any way to moderate G loads, it’s probably safe to assume the leading edge weight is so oversized to provide moderation of G forces, in addition to acting as mass dampener. Do you see anything in the electronics that would limit the G forces? Or is the counterweight the only thing moderating force?

​@@cogoid I'd really love some background info about how they design this kind of stuff. This "somewhat less competent" approach to PCB design surprised me quite a bit after watching many teardowns and reverse engineering videos about all kinds of soviet/ru aviation and mil equipment. I have seen a few things that could be done in a better way, but never this kind of "student who has no clue, no motivation, no experience bodges his way through until the thing somehow works and then a superior doesn't give a sh... and signs off on it without having a closer look" - thing. I mean, placing the passive components of an analog filter so far away from the active part is ridiculous, that's just asking for trouble. I was honestly thinking what could be a sound reason for doing it this way on purpose. Making reverse engineering a bit harder? Using the stray inductance of the long traces in the circuit? Maybe it works better if the circuit oscillates a little bit?
