How These Enormous Landing Gear Can Support 400 Tons Aircraft 

The video shows the manufacturing process, the tools, the finished parts, the size of the finished parts, the assembly process, the size and types of aircraft, the different sizes relative to the aircraft and their real world testing methods. In other words, how it all works to support the weight of the plane. How did you miss all of that?

Yeah. What A WASTE.

@@BillStemil 🤣 You clicked on a 14 minute video expecting to see the maintenance manual of a 747 landing gear? Hell, I’ll sell you one and watch you complain it’s too long.

@@BillStemil So, you said ‘yes’ you wanted more engineering info in the video, then said ‘no’ you’re not complaining about the video. Then I suggest where you can get that info and you trigger. Hmmm, I’m glad you don’t fly real aircraft, you don’t have the temperament for it.

👍

Me too!

How I wish people can also love one another in the same commitment!

@@nyccollin That’s not a question, it’s an admission of mental defects and a cry for help. Please seek professional help.

Totally agree!

Agree...

The painting is the most important part if that’s not right than they have to redo everything

@@chadbroski342 say what?

What are body gears and wing gears???

The landing gear under the body and wing of the aircraft

I would think avionics.

@@davidrico52 I would actually say the Airframe was.

@@Smakheed I think its the airframe too, particularly a heavy 12Y check

IN BALDWIN KANSAS DURING WW2 THERE WAS AN SMALL TRUCKING COMPANY THAT HAD DIFFICULTY GETTING TIRES FOR THEIR TRUCKS! ON ONE OF THEIR DELIVERY ROUTES WAS AN MILITARY AIR BASE, AND THEY HAD A BIG PILE OF AIRPLANE TIRES THAT WERE REMOVED FOR SMALL DEFECTS,AND WERE CONSIDERED UNSAFE FOR AIRPLANE USE! THEY WERE GIVEN SOME AND THEY TOOK THEM HOME. THEY WERE ALSO BLACK SMITH AND METAL WORKERS AND MADE TRUCK WHEELS TO USE AIRCRAFT TIRES! THEY THEN HAD GOOD TIRES WITHOUT RATIONING! AFTER WW2 THEY STARTED ADAPTING AIRPLANE TIRES FOR FARM MACHINES TO WORK IN MUDDY FIELDS, AND THIS THEN BECAME A BIG BUSINESS, SELLING WHEELS AND AIRPLANE TIRES ALL OVER THE USA !

OMG é Power-Phull Orrrsé-Strâylêans

Can anyone could tell me ? this landing gear this strong carries all that weight, and the pressure of plane hitting the runway could evaporate after the crash ? like they told us the plane that hit the Pentagon just evaporated went up in smoke like the entire rest of the plane, boy that must be some special fuel LOL did anyone bought that BS explanation from the Government?

You mean he put aviation tires on his road transport prime mover or his attachment for his off highway farm tractor?... Cause I could see how the latter could probably work, but there's no way anyone is using them for a highway truck. Even if you used small ones, they're completely the wrong type of tire for the application and they wouldn't last long at all.

@@C.Fecteau-AU-MJ13 YES HE USED THEM ON A ROAD TRUCK AND AGRICULTURAL USE ALSO! DURING WW2 TIRES WERE SEVERELY RATIONED IN USA ! HOWEVER AT THE AIRFORCE BASE THEY WERE THROWING THEM AWAY IF HAD DEFECTS. THE BUSINESS OF TIRE AND WHEEL CONVERSION BECAME THE HEY MACHINERY CO AT BALDWIN KANSAS! THEY ARE STILL IN BUSINESS TODAY !

Should have worn those ear defenders early on before you lost your hearing. 😂

They make a very distinct whining sound. It's not a straight jet engine like on older b52s but I would never have said I never heard them until overhead

@@scottallberry6713 So do most Americans although you hear them half a mile away.

M

Real question is why are 95% of the engines in front of the wing and always have been? Mandela Effect

True... 🤣

Saw that and was like...... Damn, guess he failed the test???

The landing gear on all aircraft get more stress than any other part on the plane. The landing gear must do this for many years. They still must be as light as possible.

28 divided by 4 equals 7? You don't say!

@@tettazwo9865 I know, it truly is astonishing, but I've run the numbers several times. Checked, double checked, cross checked and I keep getting the same result. Incredible!

Tbh that is kinda impressive. Those engines put out so much power you need 7 tires just to stop it

That just isn't true though, a blown tire isn't a catastrophic failure, and yes there is a lot of jet fuel, but you also have less momentum. It's also worth noting that taxi is the same as the runway in your example if not "more dangerous"" since you don't have enough speed to generate lift, which means all the weight is on the aircraft's wheels. As the aircraft is accelerating down the runway it builds up speed and therefore lift, as lift increases the weight on the wheels decreases which in turn makes it safer (in your flawed example). So, I wouldn't let that random guy scare you. Even assuming there was a blow out of the tires there is 2 on each wheel, which means you would have a backup and just abort the takeoff. (Which mind you is extremely rare.) Even assuming you had both tires blow out which has happened before look into the February 22nd, 2022, A plane headed to Phoenix with 142 passengers blew two tires during takeoff, but the jet stopped safely on the runway. Passengers were transferred to another plane, and no one was hurt. So, to summarize, this is just not true in any regard, so don't worry about anything in future flights. And if you really want to know the most "dangerous part" it is universally considered to be the landings. Since you are at the extremes of the flight envelope among other factors, and since statistically, nearly half of all fatal accidents have happened during the approach / landing phases of flight are the most dangerous.

Tire explodes, full reverse if speed below V1.

And they actually don't burst until twice the rated (maximum sin-service) pressure. They use a lot more rubber thickness and cord layers than car tires do.

26 ply (layers)tires and 200-250 psi. Car and truck tires are 4-6 ply and 30 psi

"(maximum sin-service) pressure"

The only Antonov An-225 to be built was destroyed in the Russian-Ukrainian war

You are correct ✅ 👍

I don’t think they’ll bring up that plane because of the animosity involved. Ukrainians don’t want to admit that the plane was actually built by the Russians. It becomes a finger pointing game. Too much conflict between the countries regarding the plane and what happened. Russia will take the plane and rebuild it. It is a historical plane and it’s not entirely destroyed. Just was damaged to where it’ll take some time to repair it. But it was a dated plane that needed to be updated and rehauled with newer and stronger components.

True. I always wondered why they didn’t spin the wheels up close to landing speed to cut down on touchdown friction. Maybe someone tried it and it didn’t work?

@@6thmichcav262 That's been studied to death over the last sixty years. Turns out to be a lot more trouble than it's worth, regardless of the spinup method employed.

Landing loads can actually be less than takeoff loads. What's not obvious watching a landing is that at touchdown, most of the weight is still being supported by the wing until spoilers deploy. Also, stroking of the shock strut serves to reduce peak loads.

@@marcmcreynolds2827 Thank you for addressing that question for me!

It's consumes to much fuel, it's maintainance is more expensive than earning😅

Hello! This is about the tyres.. so shut up already.

I think you misunderstood the video... those companies mentioned are still utilizing the A380. The video didn't say the plane was flying off of the store shelves... so to speak.

@@ejkk9513 bro check 1 more time, today's only UAE use A380, most of airways companies stop using, they use their other models

@@ejkk9513 Are you implying that airlines routinely chose between jet models they have in their inventory to serve various routs on a routine basis? "Hey Bob, which jet should we fly from New York to London today? The 737 or the A380?" "Continues to be a popular option" is understood by everyone except you to mean that many airlines are choosing to purchase the A380 instead of other aircraft, which is obviously incorrect.

And what is a tank? 🤨😂

@@jordenbronson8122 Not a self-propelled artillery piece that's for sure! What's shown in the video is a Paladin M109a7 155mm Artillery System. In other words, not a tank. Cant be bothered to explain the difference, you can look it up yourself if you want to. But a tank... that ain't!

@@jordenbronson8122 a tank is an armored vehicle designed to support infantry assaults as well as the tip of the sword to punch a hole through an enemy's defensive line, and then attack and destroy the enemy's rear echelon. a self propelled artillery is not designed to punch holes through an enemy's defensive line and continue the attack. though it is used to support infantry assaults., mainly to "soften an enemy's defensive position from miles away. self propelled artillery is also used to fire from positions that towed artillery can not get access to.

Me too. Just general stuff about planes really.

Thick SHAFTS 😮

Safety plugs that burst at x temperature.

Pavement strength is what limits tire pressure BTW, to somewhere around 180 psi for larger airports. Going higher doesn't break the pavement instantly, but does wear it out faster over time via fatigue. Same idea as with metal fatigue, where the amount of load applied plays off against the number of cycles until damage or failure.

Do they consider passenger weight per person ? Some people, like football players weigh over 275 to 300 pounds each. I know lighter weight people ( like me ,175 ) , will average out total weight plane capacity. Does the plane roll over a scale before take-off.

@@michaelcesco2970 Scales might be used in special situations such as flight testing, and some airliners have built-in gear weight sensing. What's typically used in classic Weight & Balance calculations, where no direct measurements are made, is an assumed weight for the empty aircraft, the fuel taken on, and passengers plus bags. That can be a number like 220 lb per passenger including bags. I was once told that your (American) football players scenario is in fact what designs floor strength. For the aisle, where people actually walk, floor rigidity is also a consideration. Even if it's strong enough, a lot of flexing would be disconcerting. The above is for normal-sized airliners. For the smallest commuter planes, e.g. Cessna twins, passengers may be individually weighed and then seated so as to insure proper balance.

That could be said for the B747, as it's a 4 engine jet, as well. But, the B747F could be around longer, maybe.

@@walterfink9782 not for freighter the 747 is the best aircraft for moving large amounts of cargo

The two smaller ones are Uhhhh… Attached

I got tripplé boggeis in mié Nosé

I'm afraid to say that although the C-5 does have more landing gear legs and therefore more tires and brakes, the actual legs on the A380 are the largest of any aircraft that size; both the bodies and wings alike.

It’s from Hidden Enigma
