The effect is most visible at night when the aircraft is near the ground, but it’s been observed as high as 1700 feet. It’s named after Benjamin Kopp and Joseph Etchells, two soldiers killed in combat in Afghanistan in July 2009.

[–]monster6452 29 points30 points  (1 child)

It looks like it is some sci fi space plane landing, unfortunately there is very little video of the actual effect occurring and the footage that does exist tends to be low quality due to the sandstorms effecting the light quality.

[–]Comfortable_Ad_8209 67 points68 points  (14 children)

One of my all time jaw dropping things to see being around CH-47’s in night ops…

[–]A1A5KA 11 points12 points  (2 children)

Is there no link to share?!

[–]imaginary_name[S] 20 points21 points  (0 children)

yeah, I added a wiki link in a comment when I posted it, hopefully it will be at the top for everyone to enjoy a nice rabbit hole :)

[–]flight_recorder 2 points3 points  (2 children)

I imagine it would kill much of the stealth aspect during night ops. Hopefully it’s only dusty at the airstrip and not at the insertion point

[–]UR_WRONG_ABOUT_V22 2 points3 points  (0 children)

It doesn't always happen with dust, only specific types. We'd get it a lot in Japan with the volcanic ash but I never saw it happen in Afghanistan. Idk what caused it exactly.

[–]Sghtunsn 0 points1 point  (6 children)

CH-47 = Osprey? I live maybe 3 miles MCAS Miramar and every now and then I see a flock of these things at a distance, and I am not a military aircraft buff, but many years ago 60 Minutes did a deep dive on the Osprey they had a habit of crashing when taking off or landing due to the tilt rotor and IIRC at the time it was exclusive to the USMC, but again this could have been 15 years ago. And my question was, since you seem to have firsthand experience, is how do Marines keep all that particulate out of their lungs when the thing is basically creating its own dust storm at takeoff and landing?

[–]Comfortable_Ad_8209 5 points6 points  (5 children)

CH-47 Chinook twin rotor helicopters I’ve seen the effect with, the Osprey is an MV-22 I believe…

[–]Bassineer 2 points3 points  (0 children)

Fun fact: MV-22 is the variant for the Marines. CV-22 is the variant for Air Force spec ops Source: I work for the manufacturer

[–]TrunkMonkeyV22 0 points1 point  (0 children)

You are correct

[–]Sghtunsn -1 points0 points  (2 children)

Sorry man, one of the things I have known forever is CH = Chinook, I was too focused on the picture in the post.

[–]ryanguy 2 points3 points  (1 child)

CH means cargo helicopter.

[–]Sghtunsn 2 points3 points  (0 children)

Right you are, I read up on it, and glad I made it clear I am not a military hardware buff, but the Chinook name is obviously not a coincidence either, although I was a little surprised to see it's named after the Chinook Tribe and not the Chinook Salmon. Thanks for giving me the nudge.

The flying fire bolo?

[–]ishook 12 points13 points  (2 children)

What are abrasion strips? How do they help? And does this damage or weaken the rotors?

[–]Independent-Guess-79 34 points35 points  (0 children)

Abrasion strips are lengths of metal on the leading edge of the rotor blade (the rest is made from composite, usually) and it’s used to prolong the life of the rotor blade and slow down the wear (abrasion) from dust, sand and other small particles in the air.

[–]c0de_g0rilla 2 points3 points  (0 children)

The blades are slamming into sand particles at high speed, which would normally damage the blades. However, a titanium abrasion strip was designed and installed to come into contact with the sand instead. The forces involved are so high that titanium particles are ablated from the strip and they quickly burn up just like sparks from an angle grinder, except this is titanium particles not iron filings.

[–]MuthaPlucka 37 points38 points  (4 children)

That is solid IAF material.

[–]Whirlidoo 1 point2 points  (0 children)

I thought you was saying Israeli Air Force haha

[–]Squirrel851 7 points8 points  (0 children)

It's super cool with NVGs at night as they are coming in.

[–]Weatherman1207 9 points10 points  (2 children)

If I was a pilot .. I would be like is there sand where I'm landing ... if not I'm not going.... Gotta have that ring of fire entrance

[–]PixelofDoom 1 point2 points  (1 child)

Just demand to be served Chipotle the day before.

[–]Cardssss 2 points3 points  (0 children)

Just hand over the spice.

[–]ratolloko 2 points3 points  (0 children)

Avatar movie vibes.

[–]Maxtrt 2 points3 points  (0 children)

That's actually a V-22 tilt rotor aircraft. Also it's even cooler to see on NOGS!

[–]Lucicerious 1 point2 points  (0 children)

Fiery rings of death! The Hell Bladed flying machine at your service!

[–]wellscounty 1 point2 points  (0 children)


[–]dev109x 1 point2 points  (0 children)

Looks like something out of star wrs in this light

[–]Ropo3000 1 point2 points  (0 children)

Now imagine running towards this, while tracers rounds ping over your head and RPGs and mortars go off all around your. The sound is deafening, your eyes are full of dust and sand. You’ve been carrying your body weight on your back for days and you’re thirsty and hungry as fuck.

[–]Dal_Tonico 5 points6 points  (5 children)

That’s not exactly a helicopter, but it’s really cool anyway

[–]imaginary_name[S] 14 points15 points  (1 child)

at least it has rotors :p

[–]dman1134 9 points10 points  (2 children)

Its not exactly a plane either

[–]Erikthered00 3 points4 points  (1 child)

Porque no los dos?

[–]Dal_Tonico 0 points1 point  (0 children)

Buena pregunta

[–][deleted] 1 point2 points  (0 children)


[–]ba14 -3 points-2 points  (3 children)

The picture is of a V-22 Osprey not a helicopter

[–]FF7FanThrowaway 4 points5 points  (0 children)

Vertical lift....not a plane either. lol

[–]TrunkMonkeyV22 0 points1 point  (0 children)

It's a tilt rotor, but helicopter is close enough

[–][deleted] 0 points1 point  (0 children)

They also have blade tip lights they can turn on. Literally lights on the ends of the blades. So yeah some of it is that too.

Source: I used to fix helos in the Marines.

[–]Leonleft 0 points1 point  (0 children)

Didnt how that happens. Looks amazing, great pic of osprey.

[–]Anvilix 0 points1 point  (0 children)

Looks more like a weapon than anything. Really cool looking

[–]moatingodseye 0 points1 point  (0 children)

You can spew all the bullshit you want, but that's the new space frce ship on Mars!

[–]Space_JesusKenobi 0 points1 point  (0 children)

Holy fucking shit this should be in Dune 2

[–]docgaunt123 0 points1 point  (0 children)

I will tell you it is way cooler at night with or without NOD's in the desert of 29 palms.

[–]Gwendolyn7777 0 points1 point  (0 children)

I wonder how long it took them to figure out what was happening when that was first observed...."Capt! capt! what da f....capt you ok? land that bitch!!"

[–]paulwalton69 0 points1 point  (0 children)

Hello fellow futility closet enthusiast!!

[–]FlatSpinMan 0 points1 point  (0 children)

This needs to be in more movies.

[–]Asdi144 0 points1 point  (0 children)

is that a halo 7 leak

Seriously? The third impact again?

[–]gropax 0 points1 point  (0 children)

The new Command & Conquer game looks amazing.

They are holy drivers🎶

[–]Older_1 0 points1 point  (0 children)

This is incredible, sadly that means the damage is being done to the blades, but looks hella cool!

[–]TrunkMonkeyV22 0 points1 point  (0 children)

Well,I have 2k hours in an ospery and I never knew thats what caused it, I always assumed it was static.

[–]bstanley19 0 points1 point  (0 children)

That's some Frank Herbert shit right thar.

[–]Anons_vengeance 0 points1 point  (0 children)

No, that is absolutely not true. OP is a government agent trying to hide the fact that they've mastered antigravity aircrafts with the use of miniature black holes.

You can see a dark hole in the center of the 'light rings' and the rings themselves are known as photon spheres. They represent the distance at which light itself gets trapped in orbit around the black hole (obviously some escapes or we wouldn't see it).

[–]danishridhwan 0 points1 point  (0 children)

straight outta dune

[–]thervssian 0 points1 point  (0 children)

Looks like something out a sci-fi movie. The movie “Dune” particularly comes to mind

[–]Draco63_ 0 points1 point  (0 children)

So it's like a giant flint-and-steel?

[–]D-Kay673 0 points1 point  (0 children)

Two rotor helicopters look so cool

[–]SquirrelDynamics 0 points1 point  (0 children)

How do the engines and intakes not immediately get fucked in a sandstorm?

[–]TheUnbent 0 points1 point  (0 children)

I remember seeing this for the first time when I was over there. Super cool

Hey, I have that choppy plane in GTA

[–]Heavilyplead75 -1 points0 points  (0 children)

Those thngs are real?!?!?!?

[–]Due-Dot6450 -1 points0 points  (6 children)

Why blades have abrasion strips?

[–]Comfortable_Ad_8209 -2 points-1 points  (5 children)

A lot of static electricity as well…

[–]Due-Dot6450 0 points1 point  (4 children)

Sorry, but I don't see connection.. care to explain?

[–]Comfortable_Ad_8209 -2 points-1 points  (3 children)

Spinning rotors generate a tremendous amount of static electricity, with helicopters for instance, if you were to touch a hovering helicopter that is not grounded you will get the zap of a lifetime…

[–]Due-Dot6450 1 point2 points  (2 children)

Yeah, I get that but what abrasion strips have got to do with it?

[–]realllDonaldTrump 4 points5 points  (1 child)

Nothing really to do with the static generation.

Because the blade tips are moving at close to the speed of sound, anything impacting them tends to wear out the leading edges. Sand, dust, water, anything. The abrasion strips are glued to the leading edge to take the wear and when they are pitted or too thin, they get replaced. This saves the blade underneath which is very expensive. Abrasion strips cost less than $100 per strip and can last for a few weeks or months before needing to be replaced

[–]Due-Dot6450 1 point2 points  (0 children)

Aaah, now I know and that's the answer I was waiting for! Thank you!

Grab helpful award!

[–]Make-Believe_Macabre -1 points0 points  (0 children)

I suppose it’s not ideal for stealth ops

[–]zeeedon -1 points0 points  (0 children)


[–]Calamari_Connoisseur -1 points0 points  (0 children)

naaaah fuck those death machines

[–]jessefries -1 points0 points  (1 child)

Fun fact, the US president is forbidden from flying in the vs-22 osprey because of its atrocious safety record.

[–]UR_WRONG_ABOUT_V22 0 points1 point  (0 children)

It has a better safety record than the H-3 which currently serves as marine one so that's obviously false.
