Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Important to note this is the Royal Air Force. Unlike the US, the Royal Air Force covers both land and naval based aircraft.
It's a surprisingly good idea for carrier aircraft. The landing gear on carrier planes has to be extra durable because carrier landings are rough. Getting rid of landing gear would save a lot of weight and a big source maintenance.
Worked pretty well. The only reason it wasn't pursued was because carrier aircraft do land on regular runways, and nobody wants to convert every single runway to a bouncy version.
I think that's a little incorrect. The Fleet Air Arm falls under the Royal Navy.
Though it seems that they have merged and split since original inception of the Royal Flying Corp and Royal Navy Air Service

The only reason? So they had a solution for that massive amount of friction too?
Take a look at this video: https://www.youtube.com/shorts/zZGi0Y1EPmo
You can see here how the arresting wire--which carriers have used anyway for a long time--tends to be the thing that takes up most of the speed. The plane doesn't slide against the runway so much as bounces a few times and stops.
There must be heat built up in the arresting wire system, of course, but no more than a traditional plane with landing gear doing the same. In fact, there is probably more energy transferred to the deck and the airplane skin than with rolling wheels, so the arresting wire system should have less kinetic energy turned into heat. All that heat is spread out more.
Also, not all of the energy is transferred as heat, either. Some of the momentum will make the boat go a little faster.
Soapy water! And a filled kiddie pool at the end of the runway to stop.
How would the planes taxi after landing
Sounds like a pain in the ass
