the hail test is [X(]

Why does that sexy new blade draw in more air then a conventional straight chord blade?
More area reaching out beyond the norm of the conventional blade?

i dunno, but if we could get a few of them put on a JetCat................

great engine, thanks for sharing. Joe C!!

I wish I could watch it, but God forbid my computer actually work.[:'(]

@Speed Junkie, I just did some research, and read that the fan blades are specially designed to operate at low rpm ( around 2500 rpm ) so it moves the same ammount of air as a conventional blade running at a higher speed. This lower speed allows it to meet all noise requirements.

That is incredable

Just by contrast...in 1968 - 40 years ago- the first JT9D, the biggest jet engine in the world at the time (designed for the B747) flew its first test flight and developed a whopping 43,500 lbs of thrust

Impressive engine, I guess they can fly the 747 as a twin now!

Sara,
Do you have a FOD screen that will fit this?
Thanks,
Don

I flew on a 777 and it vibrated like no other jet I have been on..

They need to put 3 of those monsters on the back of flying wing
with 1000 head of cattle on board... hahaha

Eddie

Eddie,
They probably forgot to "Locktite" the bolts that hold the turbine to the plane! [X(]

Thanks for the cool vid . I can attest to the awsome power these engines can produce ! My new ride is the 777-300/ER and 200LR . Amazing machines !

....127,900 Lbs ?.. The GE90-115B Max Power at Sea Level is rated @ 115,300 Lb.......Or does it have a reheat version...

can only go by what the lady said as being 'Most Recently'.

115,300 Lbs of thrust at Sea Level is the Flat Rating, hence GE115BL (the 115 stands for the Flat Rating Thrust Available), however with a plug change to the Fuel Control Unit the engine can produce more thrust.

At a Sea Level Airport with standard pressure (1013.25 Millibars) the engine will produce 115,300 Lbs of thrust until the ambient temperature exceeds about 28 degrees celcius, meaning that below this temperature the engine is Flat Rated.

It's always better to reduce the thrust on all jet engines as much as possible (of course maximum thrust is always available in an emergency), but we very seldome do full rated thrust takeoffs. How we do this is to input an assumed ambient temperature into the FMC (sometimes as much as 75 degrees celcius), the engine now thinks that the actual ambient temperature is 75 so it limits the thrust.

Don't want to be too technical, more of a laymens answer.

Thanks you Darryl,,,,,,,,,,,,,,,,,,,, very well explained for the layman

So… With your experience, do those engines vibrate a little more than most jets…

Or was I on just on too much crack that day… ?

Crack Kills

Hello Eddie,

They growl and rumble a lot during the start procedure, but after stabilization they are as smooth as silk throughout the flight envelope.

I think this airplane has a very bad crack in one of its windows.

Cheers

And the current -400 versions of the 747, a-la 1989 vintage with the big upper deck and winglets, have over 60,000 pounds of thrust these days per engine, and the 747-8 due out next year will have well over 70k per engine, in the basic same size package for a total of about 290,000 pounds of thrust for the airplane.

And the A-380 with four of the 'baby' 777 engines on it, pretty amazing.

The 777 variant engines are pretty cool looking, but the big -300ER versions are just monsters. Wise cracks about 2 engines going on strike during short final not withstanding.

Engine technilogy has long been the bottleneck of aerspace development, it's pretty cool to see the development these days, bit by bit.

Its not the engines that are holding the 787 back...
