Interesting Aviation and Turbofan videos

[Jay]

I am always intrigued in large civil aviation and the Turbofans that power them. Thought I would link some of the interesting Youtube videos for everyone to enjoy

3 Rolls Royce Trent 900 testing clips (Engine designed for Airbus A380)

Bird ingestion testing


Water ingestion testing


Blade off testing (nice explosion)


Airbus A330 Compressor stall, note the delay time before you hear the bangs, shows how far away the cameraman was.


Engine Hotstart (supposedly grease and oils burning off after long storage)


A good documentary clip on the testing and production of the General electric GE90-115B Turbofan (Boeing 777 engine)


Boeing 777 testing, this one is maximum rejected takeoff weight brakes testing (and wow they get hot!)


Boeing 777 maximum wing load test (until the wings break!)


Boeing severe cross winds testing (planes can drift too )


Pratt & Whitney 4084 Turbofan Testing (Boeing 777 engine)


747 engine no.1 failure rejected takeoff (must have been nice for the passengers to have seen)




Thats all for now, If anyone else has any other interesting aircraft videos or pictures please post them up, Civilian or Military!

Well I found them interesting anyway..

 

[CDailey]

just saw this thread. Awesome videos 👍 I'm becoming pretty interested in aviation myself. Do you have any links to where I could learn some more about it?

 

[Philly]

Those are pretty cool. I did a quick youtube browse and didn't find much more. All you are missing is that A320 that crashes in the trees.

 

[Omnis]

Amazing.

http://www.airliners.net/

That is a awesome site for airline based aviation


http://airreview.members.beeb.net/index.htm

This one is great to learn about the airlines themselves

http://news.airwise.com/

And this site is great for aircraft industry news

Not sure of any techincal websites on them as I haven't searched for any (I have read books for that), I'm sure google will come up with something.

Yeah, there is a couple crash videos I could have posted but I thought I would leave disaster ones like that out.

 

[CDailey]

Thanks for the links, Viper. I'll check them out.

Those bird ingestion ones are sweet. The birds just disintegrate.

 

[franz]

Very interesting videos ... didn't know they have to test all these
I always feel that the jet engines are too dangerous hanging under the wings
it looks like they are gonna fall off
that strong wind landing test is cool ... that test pilot got real skills

Yep, as long as the engine doesn't disintegrate then good.

Well actually in this case it is Boeing testing the aircrafts "LAND3" mode autolanding system in heavy windshear so the pilots arn't actually flying it in that case, but rather monitoring and preparing for a landing abort go around (They could land it themselves but are testing the limits of the autoland function).

Except the blueish/green 747 near the end, that was a full pilot landing in heavy windshear at the feared Kai Tak airport Hong Kong (Now closed).

You mean to tell me those 777s are flying by themselves? Ridiculous. On the one landing at about 25 seconds there's so much wind that the plane is still working the rudder and wheel on the ground just to make it roll straight!

Great thanks for that I'll check it out later. 👍




Speaking of Kai Tak airport here is a short video showing how difficult pilots found the airport due to mountains nearby (causing a sharp turn on final), buildings and bad crosswing





Here is a picture of another interesting approach airport

St. Maarten, Princess Juliana Intl.

It's a full LAND3 Autopilot function that includes flare and rollout modes (keeps the AC in the middle of the rwy after touchdown). All the Pilots need to do is arm flaps, monitor and engage thrust reversers until lower speeds where they take over again (80knots or so). In real service use they wouldn't use a LAND3 on those conditions.

Google it if you wish to learn more about it.

Some of those Kai Tak landings look like my GTA:SA flying skills.

 

[Bram Turismo]

THe blade testing video was simply amazing! When it began the rev up the engine to its ful lpower, it sounded like a Sience Fiction movie or something, creepy yet awesome 👍

Thanks for the vids Vip 👍

Because Boeing preferred under-wing engine mounting designs (as opposed to McDonnel Douglas and Lockheed, who preferred aft-fuselage mounts), the 747 and later Boeing liners can't tolerate much banking on touchdown.

So the Boeing landing gear is rated for up to 45 degrees of crab angle to account for crosswinds.

I thought I saw the landing gear at quite an angle on a few of the planes in the crosswind video. Thanks 👍

Yes, Engine Nacelle contact with the ground/ objects or just drawing in debris (dust etc, especially during taxi) is always a issue with underwing pod design.
747 engines have pretty good clearance but engines 1&4 are so spaced out on the wing they don't leave a lot of room if the aircraft banks on landing.

See on the GE90-115B testing video above where they mounted the large 100k+ lb's thrust engine on a 747, see how much little clearance with the ground there is . The Boeing 777 is wings are higher off the ground than the 747 to allow for that.


It's too bad McDonnell Douglas and Lockheed are all but defunct in civilian aircraft. I love the large widebody tri-powered DC10, MD11 and L-1101 Tristar (even though they still have 2 underwing pod engines). They didn't seem too favoured by the airlines and most are cargo planes now.

The blade on the one that ingested the bird moved, as its suppesed to, but didn't break off. Can that engine still be used as normal after that, or does it have to be throttled back/switched off?

And he’s there, doing this stuff, this weekend flying, and they have a word in airports- the airway industry, they have a thing called “Bird Strike.” It’s when a flock of birds is just flying along, “Oh, what a wonderful day! The sun is…” (sucking sound) They go straight through a jet engine! It’s called “bird strike,” and it’s a misnomer, it’s not true, oh no, because the birds are not striking; its an engine suck! The engine making bird soup mélange, you know? These birds aren’t going, “Who is for bird strike, eh? Johnny humans with these big metal buggers, they piss me off! I vote we go for a bird strike! Alfie, Ginger, Stevie, “Feathers” Stevens, “Big Beak” O’Reilly, Jimmy “The Penguin,” are you with me? No, you’re a penguin, so you just stay here… Come on, let’s do bird strike!” (singing “Dance of the Walkyries&#8221 "Faster, faster! 747!" (sucking sound) And just before they go through, do they go, “Look, it’s Rod Stewart on first class!” (sucking sound) We don’t know…

And I want to go to St.Maartan just so I can stand on that beach!

Here are some videos of 747s & other aircraft landing there.

JAL 747
China Airlines 747
NWA 747
Another NWA 747
SKILLZ!

Some A320s:

Odd landing
This guy is almost sideways!
Tree landing

Great fun.

I used to live in Hong Kong. It was easy to crap your pants when you sitting next to the right windows. You could feel like you are only 10m above the buildings. One of my aunt lives in those building, I could see those airlines fly by above us up-close in her balcony!! Huge, loud and scary ... I just couldn't understand why she could live there more than 40 years.

These pilots got serious skills to land in HK, specially when the storms were hitting soon. By the way, does anyone know how many passengers survived in the A320 tree crashing? It looks really bad

I'm pretty sure nobody survived.


Because nobody was on it to begin with

As the movie says, it ws the first fully computer controlled aircraft, definitly a test.

We once had a 747 fly right above our rooftops for some odd reason. That was scary but I imagine you would get used to it after awhile.

Really?

The accident and resulting fire killed 3 of the 130 passengers. Captain Asseline and First Officer Mazière, two Air France officials and the president of the flying club sponsoring the air show were charged with manslaughter. All 5 were found guilty. Captain Asseline was sentenced to 6 months in prison, plus 12 months probation; the others were sentenced to probation.

[franz]

Good lord for only 3 innocent people
but why the hell they put real people for crash test?

 

[Philly]

Did I understand the video wrong by thinking it was a conpletely computer operated plane similar to the new driver-less cars and UAVs currently being researched? In that case, there would've been nobody on board. So it was new fly-by-wire technology? Maybe they were saying "look what happens with a person in charge. He makes mistakes. A computer wouldn't do that."?

 

[Omnis]

They were doing a fly-by for the airshow. Problem was, they came in at 30 feet instead of 100.

If he was at a higher altitude (The 100ft he was supposed to be at) the Airbus's Fly-by-wire computer system would have engaged "Alphafloor" mode which automatically sets go around power when the aircraft is near stall, because he was under 50ft (from memory) Alphafloor mode did not take over.

 

[Philly]

So they were testing something to save the plane in an emergency. It all makes sense now, I think.

Kinda ironic, ain't it?

They weren't testing. It was an air show demonstration, but the pilot was under the altitude the software allowed for automatic landing abort. Since he was too low, the software forced a landing, even though he was trying to pull up and add throttle. It wasn't computer control, it's fly-by-wire, but the computer makes decisions based on its software, which was flawed.
