How Heat Seeking Missile Works I Aim 9 Sidewinder

This is a heat-seeking missile, and inside this cover is the optical guidance system.
The heat source from this aircraft travels through a set of lenses into the reticle, which spins on its axis. These infrared signatures are converted into audible tones like this sound here.

All set and done, the pilot releases the missile, which uses a solid fuel rocket as the motor to chase the infrared heat source.

The servo section controls the four canards to guide this AIM-9 Sidewinder towards the target.

However, sometimes it could lock onto the sun or another heat source instead of an enemy airplane, such as a plane deploying flares.

Later on, the AIM-9X began using infrared cameras to take pictures of where the seeker head is looking and, again, use computer algorithms to find their target.

The difference is that IIR seekers can recognize the shape of an aircraft and compare it against a database, using that information to improve their ability to track the target.

Former USAF munitions specialist here. Regarding the cooling to the seeker head, the AIM-9L/M utilized an on-board gas cylinder ( shaped a bit like a pot ) that contained 3000 PSI of Argon gas. When activated, this provided the necessary cooling as required. The Navy versions had Argon supplied from the aircraft itself

The missile knows where it is at all times. It knows this because it knows where it isn't.

Everyone needs an emotional support sidewinder.

[worthit]

You never disappointed us with the quality of animation. Keep it up. 👍

[JosephVeee]

I love the fact that some missiles have flow off to nowhere trying to destroy the sun.

Nice video but- Modern AIM-9X warheads use a Tungsten (in my language = "folded cable") warhead that slices aircraft like a sword. It behaves a bit different than HE frag but excels at cutting down aircraft- would be nice to see in an animation. It's used in a bunch of newer A2A too

one of the best channels on this platform

The missile is an amazing piece of technology and so are your videos!!! Great work!!!!

“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.
In the event that the position that it is in is not the position that
It wasn't, the system has acquired a variation,
The variation being the difference between
Where the missile is, and where it wasn't.
If variation is considered to be a
Significant factor, it too may be corrected by the GEA.
However, the missile must also know where it was.
The missile guidance computer scenario works as follows.
Because a variation has modified some of the information
The missile has obtained, it is not sure just where it is.
However, it is sure where it isn't,
Within reason, and it knows where it was.
It now subtracts where it should be from where it wasn't,
Or vice-versa, and by differentiating this from the algebraic sum of
Where it shouldn't be, and where it was,
It is able to obtain the deviation
And its variation, which is called error.”

Your quality has gone up but you should explain how the guidance system works, like how the data is transmitted to the flight controls or how the missile is able to detect the speed of a target and compensate appropriately

[tituskamau]

Hats off for the pilot who landed the aircraft with the sidewinder lodged into it.

[Eskatalogiya]

Excellent work. I've been getting deep insights about combat engineering through your videos.

Big gratitudes from Uzbekistan

[gamereditorner]

Cool! I remember learning this on the website called how stuff works over 15 years ago.

[dogwithanak.mp]

Saw a few of your videos a few months back. Came back to your channel and you're still posting absolutely awesome content. Instantly subscribed.

Brilliant illustration! So much ground (air space) covered in under 10 minutes.

[AgricultureTechUS]

This video is a masterpiece! So well-edited and engaging.

I believe this question was settled a long time ago
"The missile knows where it is at all times. It knows this because it knows where it isn't.

Despite the animations being as great as they are, the explanation leaves a lot to be desired.

[fredsmith]

someone needs to pay these people for such high quality content !!!

Where you have the warhead is a radar system. Since the sidewinder is meant to over correct its assumed it will effectively fly past the aircraft, so when it gets a strong return on the side looking radar the system assumes its beside the aircraft and pointing ahead of it, and detonates. If the target aircraft is not damaged by the initial burst, its going to fly into a cloud of debris fouling the engines at the very least
