GE90-115B Gas Turbine Jet Engine Testing & Evaluation
GE90-115B Gas Turbine Jet Engine Testing and Evaluation I takes a lot of money and time to test as thoroughly as the FAA, military, and GE require. More money and time and lives are saved by finding most problems before they become much larger. Some claim US gas turbine aircraft engines can't take turbulence or odd angles of attack. The claim is clearly false, if you note the shot of the crosswind testing fans. The crosswind fans can simulate hurricane winds at any angle. The fan and the engine can be pivoted to simulate any angle. Typically it is some former soviet block people that make those claims. They think just because they carelessly showboat fighters at air shows doing extreme AOA, that they are the only ones that can do so. The fact is that we don't make a habit of showboating at air shows because it is risky. The former soviet block has crashed a lot of fighters showboating extreme AOAs. The fact is any time you move a gas turbine with reverse airflow your risk of a flameout increases dramatically. The exhaust can recirculate back into the intake the result can be a backfire or flameout or just reduced power; all can be fatal if you are flying with no margin of error at an air show. Normally; US pilots are told to avoid doing things that can cause cavitation or recirculation, particularly wile airborne. They are tested at higher altitude in remote areas to give a good chance of recovery, and restart, and if nothing else ejection. There are some exceptions (sometimes turbofans and turboprops), but it still can be a little risky to the engine. Note this C-17 backfire. I think there was no real damage to the engine in this case. http://www.youtube.com/watch?v=BPm2z4V43Bw

one of the best engines man has ever produced... long live and more power to GENERAL ELECTRIC AIRCRAFT ENGINES

I would guess, that N1, N2, EGT and Oil Temp (or 3 of them) would all exceed their continious operation limits for some period of time to check it doesn't explode.

What does triple-redline mean? Also, what is that weird ball thing that is covering the engine intake during that test.

too small clearance between the engine airfoil and ground at that 747 test. is this engine was intended to swap its former two cf6/jt9 with this one (as some sources wrote)? and 2000+ C - is unbelievable EGT

Damn that engine is one hell of an engineering feat. GE and Boeing FTW.

that whole flight wasnt ran on 4 engines its boeing's 747 test plane, the only engine that was running this whole flight was the ge90 115b

The GE on the 747 looks so big compared to the other engines GE90 = Best engine

Yeah, my heart leaps whenever the throttles are opened. Thing is, I can't understand why.

Salemcripple: about ...
Salemcripple: about 80% of the flow bypasses the core, where the combustion is occurring. The water is ejected through centrifugal force because the air has a slight swirl to it after the fan. (This swirl is corrected by exit guide vanes) Thus, most of the water isn't going through, and whatever does go through, is evaporated. Compressor exit temperatures are about 700 deg F, and combustion temperatures are above 2000 deg F!

note that if additional 2X GE90-115B were mounted on the test 747 they could produce more thrust than the 6X D18 Lotarev turbofans on the largest aircraft in the world- the An225.

When taking off in the 777, the first thing you notice is effortless, linear and strong but quiet acceleration. You're in the air in no time.

Awesome! I like that its made in America as well :)

This engine ...
This engine represents how strong the competition between Aribus and Boeing is. If i remember correctly, this engine was only made for the 777 so boeing could make the 777 two engined, beating the A340. It is still a true testament to the GE engineers though, but thank god for healthy competition :D.

My property touches this test facility. I think GE has around 9000 acres. Let me tell you, when they engage full power, all of Adams county rumbles. I think they are testing the GEnx 2b right now, it roars!!

Revituser, I saw a special on the development of the 777 and the GE90. They ran it at 120 percent for 3 days straight with no failures.
