    That mystery pivot on the rollerons is the secret sauce that makes them so effective. The rolleron is actually a little aileron-like fin, and that pivot point is its hinge. When the missile tries to roll, the little windmill-wheel precesses and causes the rolleron fin to pivot out against the direction of roll. All four rollerons pivot like that in the same way, and so all four act against the roll.

    I'm an F-15C pilot. The seeker in the front of the AIM-9 is gimbaled. There is a magnet in the yellow protective cover and there is a pre-flight check to pull the cover off and ensure that the seeker head moves inside the translucent seeker. The seeker is cooled by a little Argon canister that the AMMO guys install and keep pressurized, the heat buildup of air friction would blind the seeker if it did not have active cooling.

      Yup. Worked at Hill at the missile shop and this was our job whenever a trailer of these came through. Most of the heads were the concrete filled ones and not the seeker heads. But when we did get the seeker heads there was a TO on checking it off for use

    From what you said, the rollerons might not stabilise the rocket, but they only stabilise the little fin they are embedded in. But when the little fin is stabilised and the rocket rolls, it creates a surface to deflect air and that in turn stabilises the rocket. Looking at the outtro: excited engineers are always a little scary to the people around them... I am one myself, I would know xD

    • Chris L
      Chris L Před 7 měsíci +10

      Yes, because the rotating elements are in counter-rotating pairs, they have no net direct mechanical/gyroscopic effect on the missile as a whole. Individually, in response to the missile orientation changing they will deflect the pivoting element, resulting in an aerodynamic correction.

    • Chet Corcos
      Chet Corcos Před 7 měsíci +1

      @Chris L I'm out of practice with the right hand rule, but I feel like this is a similar effect that causes a bicycle to correct itself. Though that could just be due to the caster angle...

      And yes if I remember my lectures in Uni on guidance correctly you are right.

    • RickyboyH
      RickyboyH Před 7 měsíci +1

      The rolling effect is why the missile is called the Sidewinder, since it looks similar to the "rolling" motion of a sidewinding rattlesnake whilst flying through the air.

    • JJ FX
      JJ FX Před 7 měsíci

      @Chris L I'm glad you said this because I was thinking, "Wait a minute, wouldn't they be spinning opposite to the opposing fin??". The net effect is a bit over my head but this makes a lot more sense!

      IIRC, the seeker head did not track well if the missle was rolling. To have the fins up front steer the missle and dampen the roll was more difficult.........might as well us those big fins at the back,

  • Geoff Powell

    My dad was an engineer on the Sidewinder and other missiles at China Lake NAWS (formerly NWC). One of my earliest memories at age 4 was going to the Sensors and Platforms section of Michaelson Lab to see how the guidance system within that dome at the front of the missile works. It was incredible.

  • Dieter MacPherson
    Dieter MacPherson Před 7 měsíci +5881

    Got you fam “The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.”

    When I was in a rocket club, we considered adding hinged fins with rollers. The reason is that when the rocket rolls, the fins will move to oppose the rotation. That's what the sidewinder missile is doing too. It's just a passive way to stop roll.

  • Pasha
    Pasha Před 7 měsíci +1

    I think it auto corrects any rotation.
    When looking from behind - if it rotates clockwise - the "mini" fins holding the flywheel will try to stay in their original position so they will end up moving counter clockwise relative to the clockwise rotation of the missile, that way the "mini" fin will generate a thrust vector from the wind in the counter clockwise direction due to it's angle and then push the missile to rotate back to where it started ~~~ I think, feel and believe at this moment in time haha :D

    When I first got into DCS, I only had the Aim-9B in war thunder, the shock on my face when I saw what the 9x and 120c could do. Now I have all kinds of half decent missiles in WT like 9Ls, 7Fs, Phoenixes, R24 etc but the performance of these modern sticks is always insane to me

    I really enjoy your observational videos about things that others may dismiss. I have always tried to understand things around me that we take for granted. Knowing and understanding things makes me feel connected to the world and makes me feel like I can come up with solutions as an engineer by understanding as much as possible. Some people would just look at a missile and say it's a missile. You look at it and see the steering mechanisms and try to understand why. This curiosity is probably why people have gravitated to you over the years.

    I am honestly surprised that you say you don't know how they work exactly. When you did the amazing series about gyroscopic precession, I learned a whole bunch of great stuff! I tell you that is one of the most awesome videos about physics and practical mechanical application of the science that I have ever seen man. I came away from that having a feeling for how gyroscopic precession works, and I have literally watched the entire series 3 times to solidify my knowledge because it is so exciting. That said, I used to ride motorcycles and I was a cyclist for decades, and I know a basic fact. I know that when you apply pressure to a rotating wheel in one direction I know which way it wants to tilt. So if those wheels are rotating, say on the bottom fin. That is going to rotate towards the back on the bottom of the wheel, which means if you look at the wheel from the right it is going clockwise. If that wheel is tilted, top to the right, Does it not want to angle front edge to the right? Which would mean that it would push that hinged fin out to the left on the back edge, which would counter the rotational force. I don't know if I have this wrong, but it seems to make sense to me. I hope you can do a follow up video about the physics of these little wheels because I'm very interested and excited about it and I would like to know if my initial evaluation is correct. Thank you for all your videos you are amazing and you and Rich my life!

  • David hogan

    The aim-9 LM rollerons can pivot when unlocked or the term is referred to as uncaged. There's a little latch that is on the back that holds the rollerons from pivoting to prevent damage to them during take off and landing. The latch will come undone by the force of the missile launching off the aircraft. I worked on these in the air force for 7 years. Great video!

      How does the pivot affect flight?

      @Username the pivot allows the panel extend into the airflow and induce drag causing force to stabilize the missile to fly straight.

      Came here to say this. But I would like to add that once uncaged and able to pivot, gyroscopic procession makes the Rollerons into an actively powered control surface. If the missile rolls right, the Rollerons will all pivot towards that direction and stop the roll. The National Museum of the United States Air Force has an exhibit in the modern flight gallery that explains how this works.

    Awesome video, Destin! I enjoy your channel immensely and it LITERALLY makes me smarter every time I watch it. As a military aviation aficionado I found this short video incredibly engaging. I never knew about rollerons! What a clever solution to a very difficult problem that must have really vexed those engineers back in the 1960s before we had accurate gyros and accelerometers that can fit on integrated chips. I also never knew about the expanding rod warhead. The way you described it made sense to me but the animation you provided really brought it home.

    Nick Shipley Před 3 měsíci

    The “side looking proximity sensor” is actually a near miss system. That gives the missile a 99% hit rate.
    The reason the rollerons pivot is exactly what you said. There’s a little tab on the back that you can flip down to release the pivot, then a little pin to lock it back in place. The tab is released inertially when the missile is released.
    I used to be a fighter weapons tech.

    I've said this before, but I've got enormous respect for the engineers of yesteryear and their "analogue" solutions. Some of the mechanisms they came up with are truly stunning and make Babbage's (impressive) difference engine look like a child's toy. I might just be looking at things through rose tinted spectacles, but in this age of just throwing more gigahertz at things, it feels like we've lost a little of the art of engineering.

    The AIM-9 M and AIM-9 X are 2 totally different beasts. AIM-9 X can be fired at extreme angles and still find its target. DCS World is a nice playground to test it yourself with the F-18C Hornet. Its pretty impressive how the AIM-9 X can find its target, i think its might be because vectored thrust like you mentioned.

  • Jim Harris
    Jim Harris Před 7 měsíci +9

    On the AIM-9M there is a latch on the back of the rolleron that unlocks from the g-forces of launch. Then the gyro part is free to swing from side to side to stabilize the missile. The AIM-9M and X uses the same warhead, rocket motor and active optical target detector (AOTD). The guidance is totally different between them.

    Can confirm, AIM-9X does have thrust vectoring. Other fun fact, the AIM-7 Sparrow missile was upgraded to the AIM-120 Advanced Medium Range Air to Air Missile, or AMRAAM. The Sidewinder upgrade was originally going to be the Advanced Short Range Air to Air Missile, but someone giggled too much, and they changed it to 9X.

      Not quite. The US designed AMRAAM while the Brits & Germans agreed to design ASRAAM. ASRAAM exists (AIM-132) but for political reasons the US decided to withdraw and focus on AIM-9X and never adopted ASRAAM.

    The reason why the roll-ons have angled instead of straight hinges is due to the discovery in the testing of the Sidewinder prototypes is that the AIM-9 airframe in addition to rolling moments also had pitching and yawing moments and angling the roll-ons hinges allowed them to respond to these pitching and yawing moments.

    The rollerons instantly reminded me of a movie from 1984 called "Best Defense". As far as I know this is the only movie about a defense technology engineer where a device like the rolleron was designed.It's a good example of how rushing something like a sidewinder missile design might lead to overly inventive solutions.

  • Alex Young
    Alex Young Před 7 měsíci

    The rolleron reminds me of the STAPAC on the ACES II ejection seat. Works by the same principle: producing negative feed back with gyroscopic precession induced by the disturbance. The disturbance may be resulted from any known or unknown factors, but the correction force by design would be simply aerodynamic like with the rolleron, or vernier rocket propulsion like with the STAPAC.

  • Aeronaut
    Aeronaut Před 7 měsíci +116

    I read last week that the AIM-9X uses the entire visible light spectrum to track it's targets, and not just infa-red like the older versions. This means that the missile is EXTREMELY good at ignoring decoy flares etc. It's a beast.

    • Rubiconnn
      Rubiconnn Před 7 měsíci +27

      Not only that but it is a high off boresight missile, meaning it the pilot can lock on targets that are almost 90 degrees in any direction with his head mounted display and the missile can quickly turn and even turn around to track targets that have moved behind the launching aircraft.

    • Spencer Coleman
      Spencer Coleman Před 7 měsíci +17

      It primarily focuses in the infrared and ultraviolet spectrums. Decoys emit some ultraviolet light while the aircraft often only reflects ultraviolet light from the sun, which helps the missile to ignore decoys too. Not only that, but this new missile will also take an average spectrum analysis of the target while in the locked, pre-launch phase and continuously compare that average spectrum against background readings to also identify its target and only track that specific target. It helps to not only ignore decoys, but also prevents the missile from accidentally acquiring the wrong target. The AIM-9X doesn’t even need to see the target to be fired at it due to sensors in the pilots helmet or the plane if launched from an F-35.

    • Brian Young

      The 9X doesn't use visible light as far as the public knows, but it has exceptionally good algorithms - and its seeker design can see the entire aircraft as an image rather than just a point of light. Rumor has it 9Xes can target individual components of an enemy.

    Destin, The Sidewinder mounted in the static display aircraft had its rollerons caged. Early development Sidewinder models had un caged rollerons and pilots could feel them fighting control inputs. Caged rollerons are released by launching G forces which flip back the small grey tab at the back of the wing. Earlier rollerons wer caged by tying opposing rollerons together with a nylon line under tension. top to bottom and left to right. On that model the front control surfaces are called Canards and the rear, with rollerons, are called wings. Sparrow Missiles have front wings and rear fins. The aircraft mounted Sidewinder could be detonated 2 ways. First by a contact fuse if impacting another aircraft and second by the Influence Fuse (Chinese Balloon Fuse), the silver cylinder behind the anodized control section which detonated the warhead in the event of a near miss. I’m a former USAF 31651L Missile Maintenance Technician. Love the Channel. Change of topic and Suggestion, find a working Linotype machine to be fascinated, also a Hammond Tone Wheel Generator which mechanically created musical notes covering nearly the entire human audible range.

    The way it leads the target is actually really cool, instead of trying to point directly at the target it tries to maintain the bearing to target relative to the missile. It was a really smart way to do it back in the 50s when computers weren't an option. By doing this it can be fired perpendicularly, and by maintaining the bearing it ends up leading the target really well. This is why, unlike in movies, missiles don't "chase" right behind their target.

    I was a missile tech years ago and the heat seekers then were the Red eye with the IR pickup similar to the aim, but I'm sure it is much improved.

    “Sidewinder - Missile Development at China Lake” by Ron Westrum is a book about the development of the missile. One of the best engineering stories I have ever read and talks specifically how they came up with the rollerons. Goes to show what happens when you have smart people on a close knit team and give them freedom to tinker. Nobody thought it would work initially and almost scrapped multiple times.

    Well there ya go, I always thought the war head was at the front or head of the missile. And thought it was just an explosive. Didn't realise it had like an expanding ninja star of shrapnel in it. Glued quite a few of them onto model aircraft but don't think I've seen a real one up close like that. I had seen rollerons somewhere before though but not sure where exactly. So maybe I have seen the control fins of a missile on something else before.

  • Nightwolf
    Nightwolf Před 7 měsíci +117

    Sidewinders are awesome missiles! Because of the way the seeker worked in the earlier missiles, it only knows the angle that it's looking, and nothing about range. The optimal way to guide a missile to a target is leading it like you mentioned, but if you don't know the range, you need the seeker to stay at the same orientation in roll (so the guidance can use the angular rates of the seeker). Instead of having a whole inertial navigation system or any complex electronics in there the rollerons let the missile fly lead instead of pure pursuits using only a couple passive parts and the missile's own airspeed! I think the inertia of the flywheels wouldn't be enough compared to the mass of the missile to keep it stable, so instead they're on those hinged pieces that essentially want to stay in the same orientation, so if the missile starts to roll, they kind of stay in the same position and act as mini control surfaces on those aft fins. If I'm not mistaken, this is what gave the sidewinder its name, if you watch old videos of them it kind of wobbles side to side as the rollerons stabilize the missile. The modern AIM-9X is insanely advanced, with a digital seeker head and all kinds of electronics, that combined with the thrust vectoring you spotted and helmet mounted sights used by the pilots, let the missile engage things "high off-boresight," up to 90 degrees away from the direction the missile/plane that is firing it is pointed. There are a few test videos on CZcams of them being fired against QF-4 target drones at insane angles while completely ignoring all the countermeasures the drones deployed.

    • Nym Alous
      Nym Alous Před 7 měsíci +5

      It just occurred to me that maybe the AIM-9X has vectored thrust so that it can be launched in a vacuum. That gives me a little bit of the heebie geebies.

    • Daniel Kemp
      Daniel Kemp Před 7 měsíci +1

      As I understand, the USSR SA-7 Grail family of MANPADS used a similar tracking system, except, the fins spin the missile at a predictable rate, correction signal is sent to only 2 canard fins.
      The fins providing correction force 90 degrees off plane, causing precession of the whole missile!

    • ////

    • DarthyBuddy
      DarthyBuddy Před 7 měsíci +6

      @Nym Alousnah. It’s pretty much just to increase the turn rate of the missile. Same reason many countries put thrust vectoring on jets.

    • Julian Holstein

    The rolleron flywheel helps with unwanted rotation (roll).

Rollerons we’re my favorite feature that I learned about any ordinance for my job. I’m glad you get to appreciate them too!

    • Pedro Arrechea
      Pedro Arrechea Před 7 měsíci +4

      I think you also wanted to control the roll of the missile because the guidance "computer" was not sufficiently complex to account for the missile rotating around its axis. It can only guide correctly if the missile is not twisting about its axis

    My dad actually worked on the AIM-9 (I'm not certain which variant, but I think it was probably the AIM-9X). He even worked at a building that was later bought by the University of North Texas and turned into an engineering college, where I got my degree. As an interesting little quirk, the building had some kind of signal blocking built into it for national security reasons back when they were working on missiles and such that blocks signals from going in or out, so students have to use the school's wi-fi inside the building, since they can't get cell service. Just a weird coincidence, that my dad would work out of that facility developing missiles, and then years later I would go to that same building for college.
