How the hell does aircraft landing gear survive landing impact supporting almost 700,000 pounds? Is it Harry Potter magic?
LANDING GEAR STRONK
>>1989887A landing aircraft has a certain amount of energy, which is to say "it weighs however many tons and it is moving at a certain velocity." To make it stop, you need to remove that energy.Work is the process of removing that energy and bringing it to a stop. Work is force multiplied by displacement (the distance over which the force operates).If you can increase the displacement, less force is required to do the work.This is why landing gear are squishy. They squish so that they receive less force by increasing the displacement.hth
>>1989908Ok since you’re obviously autistic, a better question would be how the hell do those wheels survive smashing into the ground repeatedly with so much force
>>1989933Howould,,,you weigh aplane in flight??,,,,,blimpscale?
>>1989908but airplanes don't weight anything when they're flying?
>>1989933They counteract opposing forces acting upon them with a greater force
>>1989887Also, aviation rubber sure handles a lot of abuse
>Kills commercial supersonic air travel forever
>>1989933The answer is simple enchantment cages and imperial magic.
>>1990061Blame the DC10 for fouling the runway with metal FOD
>>1989887They don't slam down all of their weight in an instant; aside from the shallow touchdown angle they go for, the wings are also still providing a lot of lift at touchdown, lessening the weight on the wheels until they finally stall after rolling for a bit. Also they have long traveling suspension to lessen the impact even further.
>>1989887They are made of the strongest metal, diamonds
>>1989887Big strong metal. Smrt good hydraulics make gear take gear go brrrrr instead sproing and clap. Magnesium break get haha hot.
>>1989933This was already answered by the person you're replying to, they simply find ways to make the wheels withstand less force to begin with. They're taking a lot still but not nearly as much as you think.
You should Google it, it blew (hehe) my mind to learn that the tires are at 200 psi. I mean look how big that tire is! At 200psi!There's tough hard little pucks of rubber are there just to grip the runway. There's a lot of stress going from whatever the speed of a landing 747 is touching the non moving ground.
>>1991756at least they're not hookless
