As a person in manufacturing for 43 years, I am fascinated by this video. I conclude by the level of quality in this engine, especially the scuffing on the cylinder wall, that this engine could only last as long as one tank of fuel. It is a one speed, one purpose, one use engine.

That's what it's designed to be, a one way drone. Why spend more money on it? Western weapons companies would've spent ridiculous amounts of money on that engine in order to charge the taxpayers as much as possible. What you see here, however, is the optimum use of resources to reduce costs.

cheap, highly accurate, deals as much damage as expensive missiles or airstrike, quick to deploy and once again extremely cheap. ladies and gentlemen, this is the future of warfare.

I couldn't help but cackle at "Korea by FAG". Seriously, though, I've never seen a demonstration like this on any other Ukraine channel. Awesome way to both distinguish yourselves and put your expertise to work. Now, if only we had a means of eliminating Shaheds as cheaply as they were made...

How about cheaper? And they do, just not enough of them in Ukraine. It is called the Gepard tank. In fact the ammo to down the drone probably costs far less than the drone. The German Gepard is the one that I know is in use now in Ukraine, and it has not only taken out drones, but at least two cruise missiles, one an Iskander, IIRC. Contrary to popular belief those only fly around mach 2 most of the way to the target, and go hypersonic in the terminal phase. Here is a video, where the idiot runs his mouth over the Gepard in operation (I HATE that), but it does show a cruise missile being downed by that machine. It shoots a large caliber explosive round, so the bang for the buck is very high on drones, and ABSURDLY high on missiles. The range isn't super far, so you need a lot of them to protect large areas. You might be able to do a large city with three or four, I don't remember the exact max intercept range/altitude, as they both matter, more of one leaves less for the other. As for next gen stuff, there are some promising laser designs, one coming out is in the megawatt class, pulsed. It doesn't take very long at a million watts in a fairly small spot to down a missile, and there each shot should be pretty inexpensive. I don't know how they power it, but ABL was chemically pumped. Like I said, the megawatter is coming, but there are already laser systems for drones in place on US fighting vehicles, some of them, and systems on subs, as well. Probably other vehicles and ships as well, but I'm not that up on them. Here is the vid. If you want to hear one, just search 'Gepard radar guided gun Ukraine'. There are a couple of YT vids shot at night, where you can hear the thing operate, and it also looks really cool because you can see the tracer rounds (again, IIRC). Other countries manufacture defensive weapons that work in this manner. kzread.info/dash/bejne/n3qTt9KnadXTmrg.html Cheers. That bearing manufacturer has been around for quite a long time, and you can find them in auto parts stores everywhere.

The Ukrainians probably won't tell you about it but I'd be surprised if they're not developing fixed-wing drones slightly faster than the Shaheds as some kind of cheap-arse SAM. But I wouldn't be surprised if it's nowhere near ready for field testing either since the tricky part is building affordable guidance and proximity fuse systems.

As an engine guy, this was awesome. Denys sent me.

This was a fascinating look into the technical side of the war. You can learn a lot by examining the manufacturer's marks and quality of workmanship. The guy on the right at the end gets 500 points for his mario shirt

Great English narration, thanks a lot for making the effort! Greetings from Sweden, I pray for Ukraine every day. I hope our military and humanitarian aid has made a difference.

Being an old aeronautical engineer, this is great stuff, Ira. I can imagine lots of other 'gear-heads' lapping this stuff up. LOL!! Very good video, Guys!!

The bearings look like critical parts. I wonder whether a special grade of bearings can be supplied to Iran that are designed to fail after X minutes of use?

The problem is not in the cheapest parts, but it's mixed with expensive and high-quality ones. This means and proves that this is Iran sh***t that was bought and collected under sanctions.

Limbachs are used in a lot of UAVs and even certified aircraft. Nice job on the disassembly vid. Ukraine is going to win this war and soon.

Never stop learning.

I'd be surprised if this was really made in Iran. I rather suspect it's an import from China and it may even be a "geniuine" Limbach engine given that the Chinese own and operate Limbach now, I believe. The cylinder barrels (and pistons) are repurposed chainsaw items from Stihl or possibly equivalent aftermarket pattern parts. The standard barrel does not have sufficient cooling for the aircraft application because it relies on the aircraft dynamic pressure for cooling flow rather than a forced convection fan as in the chainsaw application hence the cylinder tops are machined flat and additional heat sinking is attached.

Interesting I saw the original video, but this one is six days old and it just showed up.

Thanks for the translation to English

Would be interesting to see if it evolved in any way with the upcoming 'Sunflower 200' Shahed copy from China.

Excellent thank you 🧡

Nice reverse engineering jobs I will have to pass this one along to some Olson colleagues of mine

Very informative. The Iranians have had to be very resourceful for the last several decades due to sanctions so it’s interesting to show how they’re different sources come together.

@jackjones9460

Жыл бұрын

Iran and previously S. Africa show how sanctions can make countries more self sufficient! Unintended consequences.

I call it the sh*thead drone, seems more appropriate, especially now that I've seen some of it. They don't even cast the cooling fins integral with the cylinder. Man, that is some cheap ass crap. I've never even seen that kind of arrangement on an engine before. That was funny as hell, it didn't even look like a dedicated gasket, but something somebody cut out of a piece of gasket paper. In aircraft engines there is always (as far as I know) a thrust bearing of some sort, usually a flat carrier needle type. Maybe they just added it to one of the main bearings here, and I missed it? Using a standard round axial roller for thrust loads is NOT a good idea. I found that out as a kid, when i mistakenly used them for wheel bearings, actually I think they came that way, but they got changed out for tapers rather quickly. :-/ I can't understand why the crankshaft was bent, given that the rods were slammed over at about 30 degrees when the cylinders sheared off on impact. :-) I'm a little surprised at the Japanese bearings, but I'll bet they were the cheapest, lowest spec/grade available. Maybe they tried Chinese bearings and couldn't make the engine run just the handful of hours that it's use entails? That thing really looks crude. I really enjoyed that they went at the inside of the piston skirts with a die grinder, OMG...that is some precision work, right there. Yeah, not impressed with the 'high tech level' of that mount. First off, it is total overkill, and wasteful of material (If it wasn't a machined casting, but a billet part). And the finish on the part was absurdly fine for the job at hand. It looked as good or better than some the the engine internal parts. Then the machining on some of the rotating parts (prop hub?) looks like it was done with an axe, 'cleaned up' with some 36 grit paper, and then thrown around the shop for a while. That hub also looked like the collar was welded on, then a radius machined, and the weld came up short of the machining in multiple places. I can just see the engineering spec. Well collar and radius to 8mm, it is preferable to have the weld machine to a continuous smooth radius, but 20-40% is adequate. And no more than 10% can be totally without weld. Having the weld look like chicken droppings is also not advised, but not a reason for rejection. And no more than 10% of the periphery may have no weld protrusion, at all. My god, I have never seen crap like that, ESPECIALLY on any kind of aircraft, and I'm talking all the way down to RC engines. I'm guessing some of those parts were ordered from some guy in a shack, in out in the boonies Russia, a guy without a toilet, running water, and machinery to match. I don't know if that motor sat outside for a long time, but the rusty bolts on the engine mounts were a very nice touch...protective finish, ah, who needs it. Great design on the mount, too, with two opposing bolts. WTH was with that washer under the allen bolt, strange rim shape and the collar going up over the bolt head? Maybe some kind of positioner? It also looked like the bolt was about 1/2 way to being seized up in the block (or wherever), unless that white crap is just some kind of grease or loctite, or maybe anti-seize. I've not seen loctite that color, and if it were grease it would probably be lithium, which is about the crappiest grease on the planet. I have seen anti seize in that color (I think), but usually that is black or gray, the stuff I've used. It looks notoriously like what you find in motorcycles stored outside with steel bolts and aluminum blocks, where if you don't have extractors and helicoil kits, you are in some deep doo doo, because they come out snapped in half about 30% of the time given a decade and a half or three, especially the smaller diameter bolts, the 10 mm or smaller head dimensions, and I'm not talking crap designs, materials, and assembly, I'm talking Honda level stuff. Nice alignment allowance on the intake port, too. Har, har. Ah, the bolt heads practically drop through the holes, just mount it and forget it, and for god's sake, when you do the final tightening, DO NOT look down the port and make even the slightest adjustment to maintain any semblance of continuous flow. And yes, you are right, especially in high flow ports, I have seen guys taking motorcycle racing engines to every last drop of performance, and one of them said in one of the old six cylinder designs, when he put it on a flow bench, he could actually hear the flow separating and reattaching in one runner, like an organ pipe. He actually ADDED material, slightly shrinking the cross sectional area at a bend, and increased the flow dramatically. That's highest level work, to squeeze every horsepower out, which obviously isn't necessary in production stuff, but this drone is on the FAR other end. Good job. Often stuff I don't see anywhere else, as was the case here.

The Shaheds don't have man-in-the-loop control (at least not in the base models currently being used in Ukraine) so there's no need for a camera either. Just a GNSS positioning module and maybe some cheap INS based on smartphone accelerometers.

Very interesting video. Thanks. Your husband seems to really know a lot about engines.

You give them good info about things they do wrong

I wonder why Iran doesn't use bearings made in Iran. One first glance it ought to be a bad idea to rely on imports for critical materials for defence. But they may have good reason: a) They are unable to produce them in quality/quantity b) They expect their facility to be destroyed c) The drones are mainly for export, not for the defence of Iran so they are not critical for defence (indeed, Russia uses them in they way Germany used V1 and V2 in WWII - as an instrument of terror) I am with (b). They want to keep their vulnerable industry out of this.
