@lucinternet: Military helicopters flying through a sandstorm can create the spectacular Kopp-Etchells Effect, a phenomenon where the rotor blades appear to emit sparks or a glowing halo. This occurs due to sand and dust particles impacting the titanium edges of the blades at high speeds, causing a process called triboluminescence—light produced by friction. The harsh environment intensifies the effect, as the blades encounter constant abrasion from sand grains. Named after two fallen soldiers, this effect is a stark visual reminder of the dangers and beauty of operating helicopters in extreme conditions, blending science and the raw intensity of military operations.

That’s got to be bad for the blades

biggiecheese :

kind of reminds me of him

Goofyahhguy :

This to awful to the blades to fix

The v-22 is possibly the tuffest military aircraft

"Do you see it?" Our angels have arrived."

🔯🕎moistStky22🕎🔯 :

isn't it because much of the sand is quartz, and generates light via piezoelectric affect?

“Desert storm”

Daddy_LifeWeaver :

I was a an Apache mechanic for almost 10 years this shit is soooo cool in person. But awful to fix

Ur mom :

It ruins the blades too

F.I.B intergalactic bureau :

imagine a military corp named the sand angels and they go on missions when there is a sandstorm and pull up like this

like saturn rings

ENG flex kibet :

why are the comments making it harder to understand isn't the sand just creating sparks because of how fast the rotor spins

NitroPyx シ :

it's like pulling up to mars
