Jet Engine Test

The controlled testing of a Trent 900 jet engine. Glad they don't do this too often.

The Orange blade went bye-bye.

Holy balls. I hope that was a test for catastrophic failure, and not to see if it runs good.

It`s a TTD (Tested To Destruction) run, to make sure the outer frame of the engine doesn`t blow the rest of the plane up. Personally I think it`s reassuring to see how well it handles it. Very clever engineering.

^ yea.

You can just hear a countdown (or count up) before he says "fire"... I`m assuming they shoot a frozen chicken into it or something similar.

Someone should make a compilation vid of "TTD`s".

The colored blade has a small explosive charge at the base, and it explodes releasing the blade. The point of this test is to see what would happen if a blade was to rip off at full speed, and if the outer shell would contain it or not.

I saw a similar test on tv when they built the Boeing 777 long ago. It`s a fan-blade failure test. They basically detach the orange blades that are attached to the big compressor fan and it can`t send stuff flying sideways into the passenger cabin or the wing. The engine on the 777 had a Kevlar jacket around it to keep the stuff inside.

Glad they don`t do it while mounted on an airbourne plane.

Another thing they test for is the structure`s ability to dissipate the uncontrolled energy when the blade is released. It`s designed to shake as much as possible to spread it out and avoid too much of blast in one direction. Most planes that size can fly with one engine out but recovering from the spin it would otherwise produce would be very hard.

Where`s the slow motion replay?

I wonder how much it cost to test this engine?
