it dont work as good as i thought it would if it bottoms out every time on normal landings, what about a hard landing it doesnt got any more cushion to give
Incredible stuff! It really makes you appreciate the engineering of these tyres. From the flat spots upon touch down to the loading under the full weight of the plane... and repeat over and over and over again. If only Pirelli made Formula 1 tyres as durable.
First 757 Second A320 Third 787? Fourth 777 Fifth 757? Sixth ? Seventh A330 - So nice! Eighth: A320 Ninth: 787 Tenth : 777 Eleventh: 757? Twelfth: A320/19 Thirteenth: 787? I know some are wrong but which ones? :) Great video flugsnug!
Jordi- T&C noted. I expect you know that none of these landings is what a Boeing/Airbus/Fokker engineer would be consider a firm landing. A few showed initial contact followed by a second. The worse of them would be called a "shallow skip". This happens when the sink rate is near zero and minor flight path or runway grade variations cause more than one runway contact. A bounce is when the aircraft hits the runway with enough vertical energy to cause it to briefly climb before settling again. Either way, it's some damned good video!
This is absolutely awesome.. camera mounting has been so stable.. no shakes and jitters.. Wish one could also see the motion of the shockers while landing..
Really cool! I wonder if they could design little electrical motors to pre-spin the tires to minimize wear, cuz alot of rubber burns for a small time as the wheel-speed catches up with the ground speed of the airplane!
The motor system's cost and weight wouldn't outweigh the cost savings of the rubber. Remember those wheel spin up motors would be flying millions of miles in an aircraft's lifespan, costing fuel and is also a maintenance item.
if the wheels were to pre-spin to the rate of say 150 knots(170 MPH) it would cause a gyro effect and make the plane much less maneuverable during crosswind corrections..... gyros don't know the wind is blowing...they just fight to stay str8.................just my best guess
amazing, and it's so much more 'violent' an event in slo-mo than you realize! the trucks even wobble and vacillate left&right on some landings, amazing it's as smooth as it is inside the cabin. now we really know what's going on under us. and this gives you a big appreciation for those tires too, how do they not just explode? wow, great vid!
Great video! I miss the 75 even more now. That jet built up a nice ground cushion. I think it's the easiest plane to consistently roll on (of course getting the de-rotation and nose-gear touchdown was another story).
You really want to be focus on the first compression of the oleo strut and it's rate of travel - and on that regard, these landings aren't neither butter nor hard.
@@ag6371 > WoN Wheels is an electrical signal. There are Proximity sensors on each gear. When the strut collapses enough, the sensors mate and send a signal to LRU that reads the Proximity signal.
MMmmmmmmmmmmmm really needed this video. Needed to visualize these landing gear wheels going from zero to the speed that the plane is traveling. Felt like I could even swallow the impact in my throat, thats how smoothe it was.
While many of these look like bounced landings, as the wheels touch and then leave ground again, they aren't bounces at all. Instead, they are VERY smooth landings. In a bounced landing, the struts would bottom out, then extend again. But on many of these you see the struts remain extended, until the wheels spin-up enough to activate the auto ground-spoilers, at which time you see the weight of the aircraft settle heavily onto the struts and fully compress them. Interesting to see how much shimmy and vibration there is before the full weight of the aircraft settles onto the landing gear.
amazing video, great engineering. and now for a kind of silly question: would it make sense to put little fins on the rims, to give them some rotation before touchdown? wouldnt it help reduce the tire wear?
Too fiddly and space-wasting for little gain. The aerodynamic effect would not increase the speed of the wheels rotation enough to reduce wear on what are relatively inexpensive things, the tyres can be re-treaded several times before they are destroyed. The space that adding fins that would create enough rotation to make a noticeable difference would be sizeable, and would mean increasing the size of the landing gear bays, in turn reducing cargo space which could make far more money than the reduction in cost. Maintenance of such systems would cost extra man hours maintenance wise as they would be on wheels spinning at hundreds of RPM, likely needing testing for cracks/degradation every 200 aircraft hours. And finally, an important point. On take off, when the aircraft leaves the runway, those tyres are still spinning pretty quick. When the pilot calls gear up, the landing gear is lifted into the gear bays. Because you don't want a couple of tons of high speed metal whirring about uncontrolled in the aircraft, the wheels are stopped and held by a large wall of essentially brake pad like material that stops the wheel moving. If you add fins to the wheels, they will be spinning much faster as the gear retracts, and may actually increase tyre wear along with the arrestor plate in the gear bay, negating any positive effect they had. Not to rain on your idea, simply to inform. :) From an Aeronautical Engineer
***** I wanted to argue on your notes, and then I saw you signing as an aeronautical engineer, so I must respect your expertise. Thanks for the info btw ;)
surely the very fact that the moment the tires make contact with the tarmac and generate smoke due to the rubber (or what ever the tire compound is) is burning with the friction at the point of contact qualify as unnecessary ware, pulling a wheel spin every time you started a journey in your car that generated smoke, the life span of your tires would be greatly reduced.
carsos00 Very true, however, as I explained previously, that unnecessary wear is cheaper and easier to deal with compared to the proposed way of combating it. Aircraft design is all about trade offs. Electronic taxi is a prime example, companies have been trying for years to design a system that saves money and resources such as fuel and wear and tear an aircraft experiences during taxi. Only recently has it become a feasible possibility, as the technology has become cheaper and the designs have become more refined. Everything is a cost/benefit analysis, and as the proposed idea has no positive safety impact, at the moment at least, the basic principle stands that re treading a tyre is cheaper than designing, manufacturing and maintaining said system.
I think the most impressive part of an airplane is the landinggears. So much pressure they can handle. And you almost never hear about planes that had problems with the gears.
Electrics motors were tested during WW2 to pre spin the main landing gear on fighter planes. The weight and complexity of the systems couldn't be engineered out. Also a failure of either main gear electric motor sent the plane into a deadly crab landing attitude. Most of the test planes crashed . It is cheaper to replace the tires than to replace a severely damaged fighter plane and possibly kill a highly trained pilot.
Thank you so very much for this video.!!. Fascinating. There's so much that goes on every day in life that we just don't see, so I find something like this video very enlightening. I would love to see the same thing as this but in crosswinds. I think maybe the one at 3.16 was at a slight angle.?. Again, thank you.!!!.
Great video, was going to ask the obvious about pre rotating but as per other posters prob been considered already , so we get to enjoy this vids more.
1:00 - Softest landing EVER! It's amazing seeing this at such a slow speed because you can see smoke coming from the tires before it begins turning at all. Wild! Makes you wonder why there's not some simple method of getting the tires spinning before they touch down. That would significantly extend the life of those expensive beasts. Obviously they don't feel that savings (thus, safety) justifies the additional weight of a system like that. I have confidence they could create a system to take advantage of the wind speed on approach, maybe just using fins inside and out of the tires and possibly directing the wind using the venturi effect. They're bright people. LOL Ok, maybe the softest landing ever is at 2:00. Lol
I've always wondered - don't planes get flat spots on the tires when the tires are static and hit the moving ground? I mean it has to work, I'm purely wondering about the physics behind this.
Don't forget to watch this AMAZING video!

Sean Nelson dude how do you all know that?
Sean Nelson: You let down the internet as a whole for not replying, "That Fokker!"
It's amazing how often our passengers get two or more landings for the price of only one :-) 1:30

I wa thinking the same, or maybe some sort of blades on the wheels so they prespin with the wind during their approach.
The motor system's cost and weight wouldn't outweigh the cost savings of the rubber. Remember those wheel spin up motors would be flying millions of miles in an aircraft's lifespan, costing fuel and is also a maintenance item.
+Callsign Vega, I used to wonder the same, then came to the same conclusion as you.
Add a chain system, one wheel spins and it moves the rest
if the wheels were to pre-spin to the rate of say 150 knots(170 MPH) it would cause a gyro effect and make the plane much less maneuverable during crosswind corrections..... gyros don't know the wind is blowing...they just fight to stay str8.................just my best guess

crazy how much punishment the landing gear can take. really amazing engineering
This is a lot of dedicated camerawork. Thank you, it look amazing!!!
Its cool to watch how much work the shock absorbers do :O !
What is the cause of the truck bobbing such as at 0:45? I have seen 787s do that a lot. Can such vibrations be felt in the cabin?
TrainTrackTrav, I have been on an A330-200 where as soon as we touched down my row shook and vibrated (I was sitting in the wing).
I enjoyed this and im not even tired
1:53 when you know for sure it's an A330
The quality is unbelievable !
I could watch this all day its awesome to watch

Wow this is a surprisingly awesome video, I'm actually wishing it was longer....
I dont know why but I just love watching stuff like this.
Still more satisfying than any other "satisfying" video, especially the bigger planes with multiple wheels!
That's some plenty mesmerizing stuff. Thanks for sharing these.
this is really cool to see the touchdown and then watch the struts take up the landing load of the plane.
0:45 that is in slow mo and it looked hard I can't even imagine how hard that would've been in real life
You really want to be focus on the first compression of the oleo strut and it's rate of travel - and on that regard, these landings aren't neither butter nor hard.
These videos are oddly satisfying
Just love the way they bounce !!!!!!!!!!!!!
Will with it again again again again again again again
Awesome "holding up" at 1:54
As someone who works in a landing gear company, this is porn for me. Hands down best video on TH-cam focusing on landing gears alone.
Thank you, and I notice your YYZ affiliation - the A330 in the 7th shot is Air Transat from YYZ!
0:44 is pretty interesting. Wondering why the wheels are shaking like that on the 787 and not on the other planes like the A330 for example.
Very cool...and oddly satisfying. :)
3:17 was interesting. Crabbing a bit when he touched down?
Rib 5 inspection required......;)
It was allegiant
Gabriel Sasala that makes sense.
Wow! That really brings the phrase
'Weight on wheels' into perspective! Thanks for the great video.
Just for your information: Weight on Wheels is NOT when the wheels touch the ground.
@@rcairflr That's when the pressure relief valve opens and the actuator collapses

Lovely stuff, and really interesting to watch close up 👍
1:54 : what a smooth landing !!
eh
It might have been harder than it looks because the A330 makes landings look really smooth
I just noticed in the end credits that flugsnug did archive material for Skies Above Britain. Well done.
Awesome work! Great resource for mechanical engineering students and professionals to watch. Thank you for sharing!
I’ve worked in and around heavy aircraft landing gear for a long time & never realized the beating they take on EVERY landing, good and bad!
Some of those landings look rough ! Nice video
0:45 those wheels bounce like a blob xD
Very nice video! Congrats!
Superb video!! Joy to watch!!
Fair play, this is poetry in motion. Stunning.
I am more impressed with the Hydraulics shocks that the Thick , heavy , and strong tires !!
Hypnotizing!
