I'm amazed by the minds of the engineers and scientists who designed this. Absolutely fascinating. Of course, weapon systems now are even more complex!
Very primitive electronics, today in the year 2024 it can be miniaturized to the size of 10cm x 10 cm, a smartphone carries more electronics in a small space. It must be that it is very expensive to redesign a missile from the 90s. But if they do not redesign it with 7 nanometer technology, the Chinese will do better things soon.
Funny thing is all the heat sinking and such is really there for ground test, and for flying while attached to the wing, as the less than a minute operational life, when fired, means nothing really has a chance to heat up appreciably enough to actually fail. You can have operate currents 10 times the rating of the heatsink, and simply let the thermal mass of the unit absorb it for long enough, to make the problem moot. Yes expensive, but literally only used once, unless it was one of the dummy missiles, that got used for war games, where it was really only the heat seeker and lock in systems on the missile that were needed, to interface with the aircraft avionics and give the correct firing solution. Then no actual rocket motor, and no firing charge, just a fuse that was blown to indicate to the aircraft the missile engine had been triggered, simulating the electric firing charge burning out, and then you are scored on seeing if you fired the missile while it had a valid target lock. Those have no warhead charge, no operate motor, no steering motors, though they do have ballast to emulate them, and a much larger onboard battery along with a recorder to give mission data, taking up the place of a lot of this space. An even more expensive missile than the one you actually fire, as it comes back time and again.
For starters you could get your AA-2 Atoll electronics x-rayed and then of course you could always melt off the posting compound exposed the electronics.
J'adore cette electronique a l'ancienne et big respect pour celui qui a dessiné les pcb 😍 (a l'epoque il n'y avait pas toutes les aides à la conception qu'on a de nos jours).
Impresionante electrónica !!! Cuando veo algo así, me siento como un "cero". ¿Es posible que esto lo ha inventado y fabricado un ser humano? Es impresionante. Y más si lo comparamos con la sencilla construcción de R-3C.
Не надо себя чувствовать нулём) Не настолько уж это сложно. Я недавно проектировал и собирал аппаратуру радиоуправления. В качестве деталей брал такие же микросхемы с корпусом DIP как на видео (но отечественные). Понемногу решал проблемы по мере их поступления, что-то вычитывал из интернета, какие-то решения были уже готовые. В итоге, после исправления кучи ошибок на макетной плате у меня оно всё-таки заработало) Попробуйте, будьте упорны в своих начинаниях, всё у вас получится, если будете стараться.
All the "bodges" the poster is mentioning. Those are the result of design mistakes that got baked into the PCB, and the vendor decided it was cheaper to specify hours and hours of rework instead of re-spinning the PCB. Amazed by how much hand rework is on those boards!
I used to shop around electronic surplus shops in the late 70s in the UK. There were many circuit boards with identical PCBs and construction technics like the boards in the video. I always wondered what they were for, but chances are they were some military electronics. They were useless for parts because they are almost impossible to desolder.
@@armaletalia3254 It was all through-hole plated and double sided. The components were very close to the board with short leads. The chips were all soldered in like that as well.
The 54xxx series are the military version of the common 74xxx ICs, the biggest differences is the working temperature range, 0=>70 °C for the classic 74 Series and -55=>125 °C for the 54 series, otherwise these ICs are the same.
As placas com trilhas estanhadas são idênticas a que encontramos em equipamentos da HP no final dos anos 60 e início dos anos 70. Será coincidência? Muitos funcionam até hoje. Duvido algo feito em SMD durar tanto.
atualmente os misseis, equipamentos militares e aviônicos em maior parte são SMD. mas é uma montagem totalmente diferente.... e boa parte dos circuitos ainda são assim, montados em PTH. tanto componente eletrônico dedicados pra explodir bundas de terroristas kkkkkkk
Hello, je suis assez ébahi du niveau de "Bidouille" sur ces cartes, je suis étonné d'ailleurs que ça passe tous les tests d'environement, accélérations, etc....
Thank you. Can we safely say that if we want to make something similar in function to these boards with modern integrated circuits parts, it would be easier and with less components ?
Modern ones use more integration, though mostly with custom silicon, and with a lot of the electronics now being put in SMD parts in a hybrid case, making for modules that are sealed and designed to be changed out only. Yes half the volume used, but a lot more complexity, and now mostly potted, as the forces on them are much higher, so they need more protection than available from the board level conformal coating. Thus a conformal coat that is flexible, to withstand vibration, then the whole board assembly is potted in a larger volume of conformal flexible compound, and in turn this is encased in a hard epoxy outer shell, so that your inside parts are protected from vibration and thermal stress. Then machined down to a rigid dimension, and placed in the frame. Modern unit is the same volume, but this is because it has more functions, and on board telemetry to and from the aircraft, so it can provide both feedback as to the target, but also get updated targeting information over the link to ensure it hits, and ignores countermeasures that would fool these older missiles. Before chaff and flares would make the missile miss, now they ignore them, and to a greater chance, they track and destroy the original target, and give confirmation, just before detonation, that they are at the right position and target, or have missed, and are going to go for alternate targets, or try again. You have to avoid it for 60 seconds as a target to not be killed, and if you have done that, the first missile will self destruct, as it runs out of propellant, but the second one will get you.
@@SeanBZAone fix I know on these for countermeasures to magnesium flares was to ignore anything really bright as the flare was a hell of alot brighter an hotter than the jet engines so they programed in a fix that ignored really really bright an hot images in the sensor
All these type of circuit is taught in which field of engineering can you please tell me sir... Electrical or computer engineering? Please reply brother
Notice the conformal coating (wiich looks like clearcoat) on all the elctronics. Also notice all the wire-adds to the board? Where these to repair opens in the PCB/PWB or design revisions?
Sometimes to fix mistakes, often they are a mod added as a functional revision to some circuit. Later toward the end of production they might be there to adapt a replacement part(s) for some that went out of production and became unavailable.
AGM-65C was never actually produced as the seeker was too expensive, so most likely the one in the video is from R&D or testing, so therefore a lot of modifications.
Someone besides me noticed that when they disassemble a Soviet rocket produced in the 70-80s, a bunch of amateurs run in and start laughing that it’s old inside. And when a similar Western one is dismantled, the same flock of amateurs and trolls begin to admire it. This is a substitution of concepts, as Orwell wrote in 1984, that peace is war, freedom is slavery, etc.
By the weapons manual, the capacitor to be feed first from the aircraft power bus, and then giving it the lifetime to survive the X seconds (like 60 seconds minimum) after launch. This is the Laser seeker variant, so you can take this part he has on table and swap it to another one that has a TV, Infra-Red or CCD seeker instead. So you swap some of those boards (likely one out of three) by the seeker. And I recall one board is for communication with aircraft and second is for autopilot (guidance control). So if you want to update something, you switch the corresponding board only. All the Maverick missile seekers send a TV video to the cockpit via common databus. The difference is that TV, IR and CCD has the actual camera in them, where the laser version does generate the video signal as where the seeker is pointing and when it is locked. So pilot doesn't see a video but a linegraph picture of seeker position, mode and tracking. The problem with the IR seeker is that you need to cool it down first. The cooling process takes 3 minutes, but you can activate seeker before it is completed but you get distorted video or not so sensitive for thermal differences. I believe they are peltier elements, so you don't have coolant in the missile or anything, so you just feed enough power to cool the peltier and give some time to do process. You can reach -60-70 C with peltier element. The USN used coolant bottles while USAF opted for peltier elements. As you can have unlimited coolant time with the peltier. The Maverick IR variant has a 30 minute ready time after activating cooling, and then you need to stop using the missile IIRC for 15 minutes, but every minute you keep it off, you get to use again. So if you keep it On for 30 minutes and then shut off for 5 minutes, you get additional 5 minutes to use it again. But after the 15 minutes you get full 30 minutes again. So it must be something about peltier element not able compensate increase in the temperature (you use those at low altitude, air friction in the missile seeker head) that slowly creeps up until safety limit is reached and then need to recharge the capacitors, peltier etc. The TV, Laser and CCD versions don't have a cooling time, so you can basically use them until you reach X hours of operation time and need to service the seeker section. So likely the 10-15 years shelf time, and then recheck for additional 5-10 years to do again. How you can have 20-25 years old weapons, but very unlikely as those are usually used for training and anyways as it is cheaper.
@@BobbyDotNet Mavericks have IIRC capacitor as battery, IIRC a 10 year shelf time and then with servicing to get additional 3 or 5 years. And the coolant for IR seeker is peltier, so electronic. When you select maverick in station, it starts cooling period that last 3 minutes. You can uncage seeker to see video earlier than 3 min, but it will be unsuitable depending how close you were 3 min period. You can keep the seeker cooling active for 30 min, after that you need to turn the seeker off and wait 30 min to start it again. You can shut it off in those 30 min use time, and you gain additional use time for twice you keep it off, like keep it off for 5 min and you get 2-3 min worth usage time. And on launch, the capacitor will hold the power before going empty. So selecting Maverick will electrify it and start the gimbal etc.
Question: it appears boards like this do most of their computing using "hardware" components. What is the advantage in doing so compared to having it operate more like a computer with sensors to get data and software to do the computing?
The technology was not relaible enough to make it that way in the 70's and 80's. Today you could use a multicore processor to make a much smaller unit. However FPGA is still used today in modern missiles, they are faster and simpler than a cpu.
Мой смартфон, который постоянно глючит, наглядно показывает, чем плоха цифровая электроника. Аналогичная электроника работать по-другому (не так, как её спроектировали) просто не может. А цифровая может, и ещё как. Чего только стоят ошибки с плавающей запятой, баги, ошибки и прочая ерунда.
It is not a binary computer and I don't think there is any software in this missile. It contains mostly analog components and no programmable chips for what I've seen. The 'program' is 'written' in hardware components.
No, production line changes as they went through and improved with each new batch, updating the old inventory to improve things like lock in times, accuracy and increasing track capability. With the boards costing over $20k each it was simpler to do these upgrades using this than remake the entire board, and recertify the design.
@@foxxy46213 Mods. Standard practice. The mod state of the board will have been tested and approved, a contract to bring up existing boards to that mod state would have been implemented. Designing and building a new board to reflect updates would have entailed the system going through qualification again which can take years.
So this is the cancelled prototype variant ordered by USMC? Its diameter isn't stated in wikipedia...So they made it dramatically smaller on top of different guidance method. It looks to be closer to Hellfire in size
Ebay and facebook mostly these days. Some of it you can get from military disposal stores, government auctions, contractors, or from military personnel that worked on the stuff directly and managed to acquire bits and pieces. Quite a lot of it is not meant to be out there in private hands so you do need to be careful, the tech is often still classified.
Wikipedia says: " In service 30 August 1972 - present[1] Used by 30+ countries." Amazing, so many technologies raise and fold since these days. We have MEMs for god sake.
@@lelabodemichel5162 I was joking .... but congratulations if you can do it! Aside from a schematic, it would be interesting to get a description of how the whole system works.
Very interesting…what makes me sad is to see all these lovey military grade quality and expensive electronic components to be destroyed in a blink of an explosion…booom! Gone…😢
Üdv; látva az összeszerelés minőségét örüljenek a gyártók, hogy nem náluk robbant fel valami ! / kicsit az ipari gépek "gyors" robotizációjára emlékeztet ! /+ gyerekkorom barkácsmunkáira a 70 -es évekből ! (Aki ilyen helyen dolgozott anno ugyan ezt mondta !!! ) Azóta csak rosszabb a helyzet !
Wow! 1980’s technology. Analogue Op Amp with a smattering digital circuit. Jamming proof and software bug proof. Super reliable, GPS spoofing will not works here.
transistor at 4:42 is rework to fix an error in the design. LOL they glued a NPN transistor upside down and wired it in to invert the output polarity of one of the digital signals off the IC's. The designer made a mistake. In fact the designer on that thing should have been fired. LOL. What a mess of cuts and jumpers to fix design errors. That board is a production nightmare for quality control. Those people in design were terrible. The head unit is the actual optics that do laser lock on. There is a gimble steering system for the optics, there is a resolver to pick off the optics pointing position, there are transistor drivers for the gimbals those 4 big transistors. WHich tell us the gimbals have 4 degrees of freedom and that makes sense. There is a lot of symmetry in the boards because there is 4 identical driver channels and resolver channels. so that's why you see a lot of repetitive circuitries. You can see RF for each degree of freedom which means the resolver signals are not muxxed together into a single composite signal. The 10Mhz oscillator is used for a lot of things. which was a poor selection in design methodology. Because 10Mhz is right at the transmit range and there is a lot of radiated emission off those boards, that's why they have RF shieling between boards. Interference and induction between them. That whole thing is a piece of junk. You can jam that thing with a GE toaster
I'm afraid the seeker you have there is from a Hellfire, not a Maverick. The Maverick has a diameter of 12 inches. Your seeker is clearly too small. I happen to have one just like it.
