Loads Acting on an Aircraft During Deck Landings.

You claim to be doing a project on carrier landings but you want us to tell you all of the forces acting. Well the fundamental forces are gravity, weak, electro-magnetic and strong force. I lead the student to explain how these forces are relevant.

Start by searching for, "forces exerted on aircraft during carrier landings"

This is no a homework help site.

Do your own homework.

Welcome to CR4, a place for ....

Mass weight of said aircraft (+) speed of said aircraft (+) resistive load of arresting cable (=) forces applied.

Naval forces.

Good answer but it was unnecessarily wordy. I would have placed the period after Naval and been done with it.

...and don't forget the force of the wave action on the deck! Good Luck!

They shouldn't forget about the sudden rotational torque on the wheels of the landing gear. I don't think anybody mentioned the kinematics of catching an arresting cable with the tail hook or the forces needed to "stop" a plane by the arresting cable and tail hook.. (Well not fully stop, the boat is moving.) Remember too that the plane has to be able to safely abort a landing. when things miss.

I forgot to mention that all of these tail hook forces pale in comparison to the role played by the strong forces in this.

I find it interesting that you ask about the forces on the aircraft carrier. This should be somewhat easier to explain than the forces on the aircraft. Good luck with your endeavors.

Are you being snarky about his indeterminate grammar, or did you deliberately ignore the title of the post?

Definately snarky. I will admit to sometimes being in a hurry and not arraigning sentence structure well.

Also, how many of us have been lured into meetings under a false premise with what we thought would be a relevant title?

But mostly snarky.

Gravity is the force acting on the aircraft during any landing!

in the absence of lift!

Resolve your own vectors, grasshopper. There are several of them at play in this problem.

You can answer then for yourself why a carrier aircraft has such robust legs (landing gear).

Any landing on a carrier you can walk away from is a "good" landing. All of them are controlled crashes. Some more than others. All of the successful (and unsuccessful) landings end rather abruptly.

Most people have probably heard this, however, an old pilot one told me, "A good landing is one you walk away from. A great landing is when you can still use the aircraft."

Yes, and from what I have been told, when you are in WWII, piloting an F4F Wildcat, maintaining radio silence, and searching for that little dot in the wide Pacific, it can be a real homesick feeling, there is only so much fuel left, so much daylight, and so much good weather.

Then once you find it, you hope your indicators are working, the hook is down, and both wheels deployed. You have to crab the landing on the last part, but that is part of the standard approach to a carrier, where one flies across the path of the bow, circles anticlockwise from above, then you bank that final turn to line up a short approach, keeping your nose up just enough to miss the fantail, and come down on the second wire.

Perhaps the greatest stimulus in those days in favor of an excellent landing was fear of the sharks, especially if even slightly wounded.

ESDU may have information on this, but it usually requires a subscription.

They do have some free apps, but they may not apply to your problem.

The U.S. Navy has load envelops it requires for naval aircraft system designs. I don't know if they are publicly available.

They are probably available on that Russian hacker's website.

DT can get them for you, he's friends with the predident

Should be highly classified. That is one reason why I don't talk about current model Navy Aircraft, the other reason is I don't know a damp thing.

But Kudos to the Navy, my dad was in the Navy between WWI and WWII, and was on a cruiser as engineman/fireman (classification obsolete), and did witness the first airplane catapulted off a military vessel. He lived long enough to see Americans land on the moon, and also the last Apollo Mission (17), but unfortunately did not live long enough to witness the first Space Shuttle Mission in 1981.

I'd choose a helicopter landing.

Have you seen any of the landings viewed from the cockpit of a helicopter on the back of a ship pitching in heavy seas? Hint - you cannot see the deck below you at all.

Nicely done, sir! Thank you for your service! (in all senses of that sentence)

I'll second that statement.
