Startup of a Russian "type 458" gyro block of a MiG-21 fighter after almost 40years of storage
HTML-код
- Опубликовано: 12 сен 2024
- The 'type 458' gyro block (In Russian: 458МКС-15-32) in combination with the AGD-1 1122A/B (In Russian: АГД-1) type attitude indicator/artificial horizon is a part of the inertial navigation system used in the Mikoyan-Gurevich MiG-21 supersonic jet fighter aircraft. The same gyro block is also used on a big variety of other Russian fighter jet or transport aircraft still flying today!
The shown gyro block was kept in storage for almost 40years after being rejected, this is the third startup after the storage. The cover is removed, so you can see the internals of the system during startup and very basic testing.
The current setup yet lacks the matching AGD-1 1122A/B type HSI instrument, which could show both pitch and roll, so instead the pitch indicator block (syncro resolver and AC servomotor with servo amp) of a AGB-3K type attitude indicator is wired up for operation.
Power requirement of the system is 27V DC and 3x36V 400Hz AC. Steady state total power consumption of the system is around 60W off the 27V bus.
The 27V DC supply is provided by an off the self industrial SMPS capable of 10Amp output, while the 3x36V 400Hz AC supply is generated with a solid state 3phase 400Hz sine-wave inverter running off the 27V supply housed in the black box.
Don't expect much, have zero experience in video making, so video quality is rather poor as usual 😀
When I was a little kid, I had to spend the whole summer in our summer-house which was close to the military base. So these guys had abandoned fighter jets sitting on a field nearby. Unfortunately, my family couldn't afford a decent picture camera those days but I hold the memories in my head when I and dad were spending hours in that field moving jet controls, watching flaps moving, flipping switches, and even it was totally ok taking apart those jets )))
I can now recall, I was playing with the parts of the gyro in the video. I had many toys dismantled from an aircraft in my childhood.
Thanks for posting that, it brings memories about those days and my dad.
That’s wholesome as fuck. Thanks for sharing.
the earth being flat is a thought i sometimes entertain, i dont know why there is all this fluster about it, these gyros dont operate on a globe sense but a plane sense

"That's just the gyro."

I used to be a US Navy avionics technician and in-flight technician/radar operator on the E-2C Hawkeye in the 80s (last class of enlisted aircrew flight technicians for that aircraft btw). Back then we had two redundant inertial nav systems that had to spin up and cage before the aircraft moved. (this was all pre GPS) It took about 10 minutes. Then u punched in your current lat/lon and u were gtg. Both the front end instruments and back end weapons systems used those int nav inputs. The computer in that aircraft used a program on magnetic tape reels and had magnetic core memory! An 8k memory module was about the size of a large math or science text book. It was amazing how it all worked so well.
Amazing to think of how they did these back in the days of analogue/mechanical computers. Equally amazing, today a similar IMU unit with even more sensors and axes can fit on your thumb nail for a few bucks.
Fighter jets typically don't use MEMS for their INS, so no.
@@graealex True. In tactical applications and space craft mechanical gyros are used, my guess is in the event of a power failure and restart, the already spinning gyro would continue to hold orientation where a MEMS one would need to be recalibrated upon restart. That would be my guess. Still, majority of military use cases especially unmanned units and with better backup systems, the benefits significantly outweigh the cons.
@@preddy09 Again, modern fighters also don't use mechanical gyros.
@@graealex Well, will you tell us what they actually use?
@@graealex First off, all gyros are mechanical as they rely on conservation of mechanical motion. Mems gyros have damping factor so large that that they oscillating actuator stops almost instantly. If not the older "spinning disc" type mechanical gyros, newer gyros use light interferometry based mechanism. Which again is just a bunch of spinning optics where changes will result in interference. So it comes down to noise and holding time. Mems have near zero holding time. I'm guessing both spinning disc and spinning laser/fiberoptic will spin down over minutes, and significantly lower electrical interference.
This is a new lesson for me. As an engineer that's fascinating. I can't even imagine what the Millitary specs had to be for that beautiful machine.
Note to self "there is zero Indication of Altitude/depth on the "Level indicator"-(don't know aerospace engineering) so i don't Know what the "module" is called, but that Gyroscope Looks really really fascinating

@@inlasttonowhere4459 For sure it is! It is beautiful.
I own and fly a Russian civilian trainer airplane, designed in the mid 1960s which contains the original hardware such as this. I should make a video/audio of the startup of the electronics/radial engine (pneumatic start) for anyone interested. Rotary inverters (28 volt DC powered) produce all the necessary 3 phase voltages to run the gyro and Remote compass and other instruments. It has a 3 kwatt DC generator (engine driven) and the voltage regulator for the battery is a carbon pile design. All very crude but when working - very reliable. Let me know if you want me to do this. Cheers, Phil
Let me guess, you're talkign about a Yak-18? 🙂
@@barjan82 A Yak 18T to be precise. Mine is one of the ones in the last production run built in 1993 at the Smolensk factory.

I love Soviet tech--it's either amazingly robust and overbuilt, or totally insane and shoddy, or BOTH! Either way, Soviet stuff is really really cool. What an incredible little machine, thanks for sharing it with us.
I would describe soviet tech as extremely simple, perfectly designed for the task, making it extremely reliable. It doesn't stand out, because it's not over engineered to prove anything, remember the tanks in WW2.
Military, yes. Civil, forget about it. Total junk. All the resources were prioritised to military tech.
I agree.
@@forwox
I have to disagree. For example soviet cameras Zenit were quite nice. And there were other examples of civil goods that are not junk.
Don't you realize that all this is a copy of British, German and American technology?
I used to work on A-6E Intruders that had IMUs like this. It was in a sealed gold box in the nose wheel well and was painted gold because, we were told, it was worth it's weight in actual gold. It weighed like 25kg and whined loudly like this gyro.
-aha, that's the "Russian gyro" concept was stolen from.
For such a simple mechanical device I never knew they could get so complex. That thing looked like it would open a portal to another dimension
mass effect mass relay
And to think everything that makes that incredible piece of technology was just random materials in the ground at one point and someone turned it into that
Yes the result of building things that build things. The construction of this and a lot of things started a long time ago with unrelated items.
This kind of thinking is what we need.
@@johnnycash4034 Yes, today we are born on, but have the choice to stand, sit, or fall off of the shoulders of giants.
Exactly. People living 5000 years ago could have built a microprocessor if they only knew how. Everything was already there except the knowledge.

You understand the basics, so you understand what it does!
Why he needs it? mad!
I love stuff like this, part of the reason things like the Saturn V or the SR-71 are so special is because the control electronics are electromechanical. Don't get me wrong, I love being able to buy an IMU, stick it on a breadboard or perfboard and it just works but there's nothing to it.
I really wish there was still a place for electromechanical stuff like this today, because I enjoy the mechatronics much more than just electronics but it's sadly obsolete AFAIK.
It's funny though, tons of US military tech, especially missiles and planes, is from 50-60 years ago and still uses electromechanical tidbits, even if upgraded ones.
I also love how this sort of thing is the thing you can actually repair, not just desolder and replace.

Guess what system f15's and f16's use today? Yep, mechanical gyros. Hell, even the f22 uses them. Military technology isnt as advanced as people think...
My dad had some gyro from something ww2 that was air powered. Had a 3" brass wheel with little cups cut in the rim for air to blow it around. Everything required amazing workmanship before computers.
If you check my latest video I get one of those working:-)
Still does take workmanship in a way, but I know what you mean. Elegance. Cessnas still use something similar to this day though.
Even now, in light aircraft some instruments are air powered, and others are electric, the idea being that a single failure won't disable all the instruments.
@@sylviaelse5086 Ram air power is cool
That was from a Torpedo.
Incredible to see this kind of technology, which was so advanced once upon a time

youll be telling your grandkids about heatpipes and theyll be looking at you like your a caveman 😂
Well, if don't configure a modern IMU properly and don't filter the output with the proper transforms...it's gonna be WAY worse than a mechanical gyro!
@@luminousfractal420 emulate it you meant, or use Russian sofjet skills to build it!
The lack of drift has always amazed me for a mechanical gyro, a lot of thought and design went into that.

Always amazing to see. I used to think that gyros were much simpler.
They actually are.
But in aerospace they have to deliberately make everything sophisticated so that it’s rock solid and full proof operational for decades to come.
@@shuklavinays Airplane mechanic here.
*Redundancy* is the name of the game in aviation. NOT complexity.
Aviation equipment isn't built complexely for the sake of being complex, as your comment suggests.
Quite the contrary. If a simple system can be kept on an airplane, it is. The simpler something is, the less likely it is to break, and the easier it is to fix when it does.
The so-called "complexities" you speak of are backup systems for those primary systems, in case the primary goes wrong.
Some components have 3rd and even 4th stage redundancies. But most only need to be two.
The idea being, not necessarily to make the equipment last as long as possible. But to get you safely to the ground, should something go wrong.
If a car's ignition system stops working, all you have to do is glide to the side of the road, slow down and put it in park.
Tf are you gonna do when you're up in the sky and your ignition system fails?
A safe glide to some flat surface AIN'T a garantuee.
So airplanes have *2✌️* ignition systems. Because the odds of both failing simultaneously are astronomical.
@@davecrupel2817 I was just going to say redundancy
@@JoeKyser damn right. The more and better your redundancies, the better your machine can catch it's own ass when it slips and falls.

I love the lead dress / cable harness, it's so clean and neatly made. Wonder if they used high flexibility cables, or just the regular stranded stuff.
They use the highest quality stuff. The most precision components and best materials for military.
standed or not i dont know but i have some of their silver solid core they used for communications (i used it for a custom headphone cable) fairly flexible but any tight turns would demand stranded as it would snap solid core. could be a clue
@casper . the hind is a beast

Almost certainly stranded. Lacing like that was standard practice in the period. Still have a reel of lacing cord somewhere...
I can feel the smell of this trought the picture :D
I can see the taste of it through the speakers.
This gyroscope technology is still relevant today. Microcircuits will not withstand an electromagnetic pulse from a nuclear explosion, but a mechanical system will work.
Very good point and pertinent in today’s threat environment too. It’s worth noting that a vacuum tube transmitter will still operate after an EMP, not much else electronic will.

About Ukraine. Pay attention to my Ukrainian surname - my parents moved from Ukraine to Russia during the Soviet era.
Ukraine at the collapse of the USSR in 1991 had a more developed economy than Germany. Now her economic development is worse than that of many African countries.
Ukraine's population declined by 20% in the years after the USSR. About 5 million Ukrainians are guest workers in Poland and other European countries, and about 3 million or more in Russia. Etc.
Ukraine is an extremely toxic asset, its occupation will be a millstone on its back. Everyone understands this, and of course Putin does not want the occupation of Ukraine.
But! War in Ukraine is possible. It is possible in two cases - a military operation by the Ukrainian authorities against the rebellious republics in eastern Ukraine or the deployment of NATO (US) forces in Ukraine.
In the first case, it is important that the eastern regions given to Ukraine in 1921 are totally inhabited by Russians. More than 700 thousand residents there have already applied for and received Russian citizenship, and more than one and a half million are awaiting the consideration of documents. Putin cannot ignore this and deny them protection, otherwise his support in Russia will collapse.
In the second case, a US missile so close to Moscow is an existential threat. It is important to understand here that the conflict in Ukraine in Russia is perceived as a conflict with the US controlling it.
In both cases, missile strikes on Ukrainian military infrastructure or on US missile launchers (like Israeli strikes on nuclear facilities in Iran) are likely, but not occupation. This is a very unlikely event, more likely the reciprocal deployment of Russian hypersonic nuclear missiles in Venezuela, Cuba and other countries hostile to the United States.
And this is the real danger of the Apocalypse.
With digital cockpits don’t hear it much but when I learnt to fly the gyros running down after shutdown brings back memories.
Weird power requirements, 3x36VAC at 400hz and 27VDC. What an incredible mechanism though!
Probably had 400hz generators on the plane (for radar and whatnot)… just coupled the gyro to the same power supply
A lot of planes, submarines and other military hardware runs on 400hz.
As a retired machinist & electronics hobbyist, I LOVE to see electronics / Engineering interfaces... this did definitely not disappoint... 😎👍☘
So that runs shy of 30v DC? Impressive piece of older technology you got there. That is awesome. Thanks for the video of a mechanical gyro
It requires a DC voltage of 27V and an AC suppy of 3phase 36V 400Hz. The black box contains every stuff needed to run one or more instruments, an off the shelf 27V 10A SMPS and two 27V to 3x36V 400Hz solid state sine inverters, capable of 150VA output each.

No. Chips only in cheap electronics like phones where nobody cares about precise and reliability. Jets and missiles still use professional gyros (mainly based on laser).

The crazy part is that tech has come so far that there is a similar device in everyone's cell phone that tells it when to rotate the screen. Today they're microscopic and made from piezoresistors attached to suspended masses all made with the typical silicon photolithography process.
Check RUclipsr: Afrotechmods he has video on that subject, how ic gyroscopes works.
He explains it as capacitance, a photo lithography fork shaped things on each of the 3 axis, since ic's contain metal oxide parts grown on there and metal plates generate capacitance.
but these ic's also or some contain accelerometers, that's where Piezo technics might be use full.
An accelerometer or a magnetometer is not the same as a gyroscope.

Да конечно очень крутая штука для своего времени. И удивительно, как в наше время выглядит МЭМС аналоги, которые стоят практически в каждом современном телефоне. Хотя наверное они не такие точные и надёжные.
С гидроуровнем сравнивал мобильник, горизонт чётко показывает
Начнём с того, что MEMS не аналоги этого девайса ни разу. Ибо они акселерометры, а это гировертикаль.
MEMS'ы умеют эмулировать часть (!) функций гировертикали за счёт программной обработки, но не более того. Плюс программная обработка ведёт к накоплению погрешностей гораздо более быстрыми темпами, чем у гироскопов.

In the 1950's most of the instruments in B-52's were old vacuum type electronics. The DG and Attitude gyros were much smaller and self contained in the panel type. The older types with remote gyros were used on the B-17, B-25, B-24 and B-29 but the bomb sight (Norden) had it's own gyros and they were much more stable.
Those РЭС-22 relay modules were really ubiquitous. Didn't know they were used even in gyros.

Umm....no they don't. Modern Ring Laser Gyros are significantly smaller and more accurate but not on a "tiny chip eye can't see".
To reiterate that we are talking about gyros used on fighter aircraft only, not INS on a MEMS type systems.

In my opinion it is not an inertial platform, but a gyroscopic artificial horizon. The inertial platform is something else.

Not ADG-1! AGD-1!
even the gyro have it own jet engine... what a machine
Waiting for new video : launching mig21
R-60, air-to-air missiles, after 40 years of sitting.
Ооу я помню похожие штуки на заводе собирал, говорят их до сих пор собирают с небольшими изменениями
Это вряд ли😹, может вывод у них совместим, но внутри уже оптика и плис.
@@hrissan собирают и лазерные и механические, узнавал))
@@andreasspizinn5073 удивительно, что люди не забыли, как это делать. Прям восхищает.
Whoops I still have one of these and an roci and use PT500 to power it. Works fantastic
How do you power the PT-500 rotary converter? It draws a stupid amount of power on startup 😀
как же я люблю этот звук....
И это в 1978 год 🔥🇷🇺👍
Sweet! its still working From that to a to a block on a computer chip Cool to see how far technology has come
For something that's 40 years old and still working they don't make them like they used to
Here's the thing. It hasn't been used for 40 years but its actually even older than that. crazy
@@akosmaradi5281 yes I know that👍
Soviet stuff was built to last
Sounds like my old desktop computers in 2000. My father used to say "It's about to take off like an airplane".
Awesome! Pitch seems to be working fine, why there were no changes in roll on HSI when you rolled the gyro?
This was only a very very basic setup with a part of a hsi that could only show the pitch information. To check how it shows the pitch and roll with the matching hsi instrument check the very short demo ath the end of this video: ruclips.net/video/xL5fZ5dPcso/видео.html
Totally cool to see that!!
That thing spins serious Rip-em's.
Ok.. That was stinkin cool.
My wife: What is that noise
Me: A fighter jet gyro on RUclips
My wife: ooookkkaaayyyy....
I would have happily sat for another five minutes listening to it spooling down to a stop :)
What a well built bit of kit.
So small and reliable after 40 years.
Russian engineering was as God as ours in the West.
Unusually 3 x 36V AC was this beacuse of failure redundancy.
I think 400Hz is the same frequency used on the DC3 and Grand Commander I flew on survey with it must be a standard for aircraft.
Do you have any other pices of electrical or mechanical equipment from 40 or mor years ago.
Thanks for the video.
Small mate 🤦♂️ u should see one of today
Anthony....., is the Earth flat , or a Globe ?
A thing of beauty 😍
I missed the sound of an inertial gyro spinning up. The N-1 on RC-135s sounded the same. It took 28 minutes to fully spin up.
Thank you for sharing, that kind of things is always interesting.
Very nice. Did you have a service manual to identify the pinouts and supply requirements or did you work that out yourself?
Dave, supply requirements were strait forward as Soviet military instruments this era usually run at 27VDC for the servo amps and for a bunch of relays and 3x36VAC for the gyro motors and syncro transmitters/resolvers. Pinout for the supply input was easyer and follows some regular Soviet scheme i've seen on other instruments as well, first 5pins on the bigger connector carries both DC and 3phase AC supply inputs (1->GND, 2->27V, 3->PhW, 4->PhV, 5->PhU). The rest of the pins were including a bunch of head straching and lot of DC, AC voltage and oscilloscope measurements while the unit was running.
@@barjan82 Awesome. Thanks for the info!
@@sircompo U're wellcome! Take care about the 3phase 36V AC supply phase order on pins 3-5. The gyro block will run with any phase order conneted, but however if the gyro block is connected up with the proper 'display instrument' and the 36V AC supply phase order is incorrect the complete system will behave false. This is valid for both the 'type 458' gyro block and the AGD-1 or KPP-1273 display units.
@@barjan82 I'm hoping to get a Smith's Industries horizon hooked up to a sim. I suspect it's expecting 3 phase 115v 400Hz supply for the synchros. Gonna be fun figuring that out! Suspect as it's a military part from a VC10 I'm not going to find service manuals!
@@barjan82 а частота тока 400 герц?
That’s awesome. It looks like 1980s wiring and connectors also.
I never though the gyro was separated from the instruments lol
Depends on the system and manufacturer. Usually smaller units has everything in one box sitting in the cockpit. More complex artificial horizons may have a separate hsi in the cockpit and a sensing gyro block somewhere else in the airframe.
That looks pretty cool
can anyone say we want to see gimble lock?
I left this video running while doing chores, and my wife runs in and screams WHAT IS THAT NOISE. I look at her wide eyed and said. "OH MY GOD, it's the gyroscope from a mig!. She was not amused.
Incredible tech even for today.
Now you have a beauty and heavy 3-axies steady cam.
