    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.”

    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.

    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.

    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!

      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.

    Somthing I heard from a Navy guy when I was in the USAF Reserve. One of his ship's aircraft came back from a mission with a North Vietnamese air-to-air missike sticking through the tailfin. It was very carefully removed and taken down to the missile maintenance shop. Several people had noted that it looked a lot like an AIM-9, so the seeker head was carefully removed and put on the AIM-9 test rig. It checked out perfectly! Furthe examination of the missile showed it was "probably" a Russian copy of an early AIM-9!

      Soviet AA-2 Atoll missile was a copy of the AIM-9B. the first people to use the Sidewinder in combat were the Republic of China (Taiwan) Air Force in air battles against Communist China in the late 1950's. In one battle, a PLAAF Mig was hit by a sidewinder which suffered a warhead failure and got stuck in the Mig's airframe. the Mig got back to base and the remains of the missile were given to the Soviets, who copied it.

    • @rubiconnn
      @rubiconnn Před rokem +29

      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.

    • @SupernovaSpence
      @SupernovaSpence Před rokem +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.

      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.

    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.

      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.

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.

Early AIM-9P missiles used string that held the rollerons in position. The rocket motor burned the string off at launch, uncaging the rolleron assembly.

    Awesome. For over a decade I was a soldier (Redstone Arsenal) then civilian technical advisor/instructor (Ford Aerospace) to foreign militaries who purchased sidewinder (air-to-air) and Chaparral (ground-to-air) missile systems. And the rolleron was always my favorite part for its elegant simplicity. That said, the guidance system is pretty elegant as well. I was fortunate to have worked with the engineer who originally designed it. Those OG engineers solved some incredibly complex problems with very basic tech including intercept (not chase) in 3 dimensional space, how to pivot a guidance fin (very high torque), and of course the rolleron.

    The ir guidance system on there is also genius: because of the technological restriction of the time, it had to be fully analog. What they did for the sideweinder was to place a rotating disc divided into sixteen sections, with one in two section beeing opaque, and one in two being transparent. Behing the disc was the ir sensor. When the ir signature of the airplane moved across the disc, the sensor would output different frequencies, as the the black and tranparent sections were blocking/letting through a diferent amount of light at different frequencies depending of the position of the ir signature. The outut frequencies could then be analyzed and the missile would try and correct until the output frequency matched the one that would mean the target is centered.
    Pureley genius!!

    @Nightwolf323 Před rokem +116

    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.

    @jcstudios7099 Před rokem +7

    Destin, awesome video, I love to see how excited you get about life and the things we humans create. To answer your question about rollerons, they provide stability primarily with aerodynamics. The gyroscopic stabilization acts on the flight surface more so than the missile as a whole. The cool thing is, it's completely passive.
    While in flight, as you said, the flywheels spin up and the movable tabs are locked in place to prevent tab movement while the aircraft is maneuvering. When the missile is released, those tabs unlock and become free to move. Because they are held in space by the spinning flywheels, as the missile rolls, those tabs will remain on the axis of the flywheels. Like a trim tab on an aileron, it will aerodynamically counteract any roll induced during the weapon's flight.
    I hope this helps you understand rollerons better.
    PS. I can't wait to see you experiment on those newly acquired fins.

    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.

    This is why I subscribe to your channel. It is so clear and obvious that you just love learning and sharing that learning with others. Anyone else would have gone through google or one of your many contacts to find out exactly what the pivots on the rollerons do before even attempting to make this video, but the vibe this gives off is that you just saw something as you were walking past it and wondered how it works so you made a video. Thank you for all that you do.

    I built an actual size replica of the AIM-9 L/M for the Southern Museum of Flight, back when I worked there.
    You might want to try this for a little fun…
    Take an air nozzle and air compressor (maybe 100 lbs psi)
    to spin-up the rolleron gyro and listen to that thing whine !!

    Oh dang, I think I just had one of those inspirations moments you have when figuring something out with those rollerons. So each of the 4 will have an angular momentum vector but the vector will be in the same tangential direction (clockwise as viewed from the back) around the missile (via the right hand rule) so the vector pointing directions are very important. Now it's doubtful conservation of angular momentum of those relatively small pieces alone will be enough to prevent a rocket moving at a high rate of speed from rotating, however as the rocket rotates that little piece on a hinge tries do try to conserve angular momentum so the flaps do move, and they move in the same tangential direction to the rocket's radius this is basically creating flaps which absolutely do create a counter drag to the rotation preventing it from spinning widely out of control.
    Now if this is common knowledge, I'm sorry, but yeah I just got a very inspirational "OH SHOOT I FIGURED IT OUT!" moment which kind of gave me a little tingly feeling. Thanks for making these videos.

    Destin, the roll motion is stopped by the gyroscopes precessing under roll and thereby deflecting the aerodynamic surfaces to which they are attached. It is not so much the rigidity in space of the gyroscopes doing the work as the deflection of the surfaces.

    I'm always blown away by how you seem to know so much about so many different things. Made a bit more sense that you might have just learned about rollerons from the informational plaques around (unless you already knew about them?!) but I'm still blown away by the fact that you noticed the tiny divots and knew what they were and why they were there. Great video, thanks Destin!

And thank you for showing us that clever passive engineering solution.

    A bunch of years ago, the local air national guard group had a display at the state fair. They had a Sidewinder missile. I saw the little "spinny thingy" at the rear of the fins. I spun it, studied it a while, found the hinged section and it dawned on me. NO WAY! THAT'S THE COOLEST THING! Easy to implement too. No electronics.
    Thanks! I love your giddy enthusiasm for this stuff.

  • @f38stingray
    @f38stingray Před rokem +1

    5:18 - the AIM-9 was one of the first missiles to lead targets with proportional guidance, and it's a cool point. It's also why stabilization is important. The seeker is a simple IR detector (no pixels or built-in direction sensing) and figures target direction with a spinning mirror that makes it continuously scan in a circle in front of the missile. The hottest part of the circle is where the target is, so the missile leads by comparing how much hotter one part of that spinning circle is than the rest.
    Thing is, if the whole missile (and not just the seeker) spins, then you don’t know if the hot part of the circle is actually still pointing at your target, hence the rollerons to stop roll. This is why the AIM-9X has no rollerons - its seeker is more like a camera, so it can find direction just by seeing which spot is brightest, so roll doesn't matter. Everything's connected!

    I would love more in-depth videos on how missiles work like this one! It's rare for me to see them up close like that, really neat stuff. And I have also loved the idea of the rollerons once I figured out what they were. Assembling models as a kid and seeing pictures in books they looked so weird since no other missile had those rollerons (except the AA-2 Atoll which was just a reverse engineered AIM-9).
