Kevin -- Why waste good rounds? Jerry has the right answer with reversing battery cables (or whoever you want to do it) to fry the electronics. Anyway, bottom line is that the best way to ensure all of this stuff gets destroyed is to merely stand back and let the Taliban actually try to use it. smile

I'm thinking that a couple handfuls of sand into the intake will take care of things in a bit.


Another quality post.

Those engines ingest sand as a daily diet in that area, so it would probably take several shovels full to do anything dramatic- - - - -look at what happened to the "rescue" mission for the Iran hostages back in the dark ages. Flying low and slow in a sandstorm kicked up by other helicopters' rotors was much more effective at disabling turbine engines than any sort of ground fire could have been. Now, a handful of nuts and bolts into the intake of a jet engine would probably be a lot more effective, and do its work faster.

John has the best idea- - - - -just paint a big "This side up" sign on the instrument panel- - - - -with an arrow pointing down!

Has Rod Serling been reincarnated? It seems like we're living in an episode of "The Twilight Zone"- - - - -but it's going to be a long time before the commercial break comes around!

I saw a photo on the news. It showed all the instruments bashed in.

Rusty ... Brother Jerry is correct. About 20 years ago, we learned from the Russian experience in Afghanistan (their jet engines had longer life spans in desert environments than ours did). We discovered that they had developed a process to coat their compressor blades with Titanium Nitride (TiN). Extended their service lives and performance in an abrasive/corrosive environment exponentially. We licensed the process from them, set up a company to do it for most of our helicopter engines (exclusively GE for DoN rotorcraft) in Prince Edward Island and now you can almost aim a sand blaster nozzle into our engines with out serious degradation (for awhile ...). Nuts and bolts would work better. Or simply draining the oil out of the gear boxes (and refilling them with shampoo.. .) . or taking a ball peen hammer and merely bashing a few little dents into the tail rotor drive shafts ... or remove the upper half of a hanger bearing and cut just a nick into the driveshaft with a sawzall -- not too much or they won;'t even get off the ground) and replace the hanger bearing cap ... or loosen a nut (any nut ...) on the main rotor swash plate .... remove a safety wire here, a cotter pin there ... very simple to introduce a catastrophic failure into a rotor craft wink especially when those rotorcraft are being operated by 8th century brutes who wouldn't know a vibration damper from a pogo stick and haven't been extensively trained how to do a proper preflight ... wink

If you're pressed for time, George's approach works pretty good, too. Not as entertaining, but still effective.

My friend and fellow sports car racer who ran the jet engine test stand at Kadena AB Okinawa used to "decarbonize" jet turbine blades by pouring several pounds of finely ground walnut hulls into the intake with an engine running at about 50% thrust. That put some epic flames out of the business end of the engine, but the turbine blades can me out nice and shiny. I use something similar in a vibrator polisher along with a good dose of jeweler's rouge to shine up brass cartridge cases for reloading.

What John said! If they remain obligated to remain in the 7th century as many have stated then more attempts to run anything will be destruction. Their society makes nothing mechanical. I would like to know who sells them all the Toyota trucks. doc

When those trashed instruments get replaced, they'll be calibrated in Pakistani, Chinese, Russian, or Farsi. Nobody expects the "indigenous" troops to ever operate any of that machinery!

Jerry -- the walnut shell trick is still used. In the field or aboard ship, though, they use a simple water hose. I'm not sure the exact procedure but ... when they put the water to it, the black crap that comes out the back is amazing. When we went to Bangladesh for Operation Sea Angel, the Bangladeshis were having issues with their Mi-17's losing power. Our Marines showed them the water wash down trick and they were amazed at how much power they got back after simply aiming a fire hose into the inlet of a running Mi-17 engine to wash the crud out of it. It think its sort of like steam cleaning as the water turns quickly to steam in the hot section of the engine and the steam hits the blades in the turbine section. Just the water and the pressure does the trick in the compressor section.

The B-52D's I worked on and flew on occasionally used J-57 engines- - - -known to us wing nuts as "water burners". They used water injection to keep from melting the engines during max-load takeoffs. The KC-135 (Boeing 707) used the same engines, also with water injection. One pilot at Grissom AFB Indiana proved that if a KC starts a steep dive at 10K feet and hits the water injection, it can pass a B-58 that's doing Mach 1! The fact that it happened during a low-level high speed pass by the 58 during an air show got the pilot and the plane grounded for quite a while!
