PLAN Carrier Operations..News, Videos & Photos

They are basically throwing the aircraft into the air.

that's the magic of physics and air pressure! what you see with your eyes is deceiving. The aircraft while look 'slow' to you is actually experiencing massive lift. SU 33 is a BIG plane so it looks slow. Don't forget the carrier is turning toward the wind as well so the wings and flaps are catching a lot of wind pressure underneath it as well.

Ever try holding an umbrella in 30 mph wind? even the strongest man would say it's difficult. Now imagine your umbrella has 50 times the surface area and the wind is 5 times stronger?

The wind will break the umbrella...

The lift of the aircraft is much less than its weight so its trajectory is curved while it accelerates to flying speed.
Aircraft carriers should be as small as possible while still being efficient. That "being efficient" depend of course on the purposes for which the ship is to be used. For USN that means supporting the invasion of a country on the other side of the world and we cannot doubt that a 100k ship is appropriate. Less ambitious countries are better served by smaller carriers with fewer aircraft. But such ships do not want to sacrifice so large an area to cats nor, even worse, to a large deck run to the ski jump. The solution must be to use cats that provide the aircraft with the same velocity horizontally and vertically as the ski ramp by integrating the cat into the ski ramp.

That's the reason why the Su-33 has canards to prevent it from stalling at high angle of climb during a ski jump.

What if you have a flat deck, but allows some mechanism that raises the front wheel of the aircraft being launched, so that it is catapult-launched straight, but with nose at an angle into the wind?

You mean this old britisch technic?

Well the only way that will happen is if you and I go to Cuber, and relieve the bros castro of the burden of leadership, and as your brother of course I would let you try it, just for you to see for yourself. Now the pilot says I want as large a deck as possible, I'm afraid this small deck stuff is just because you're a "tight dutchman", any way it would be more banana republic than dictatorship.

I don't know how the Brits found it, but it would present additional concerns in a foul weather recovery especially. That long nose gear means you have to be very precise, or maybe it was just for launch, in which case it would be helpfull. Anyway I have flown a coupla riggs with short mains, an proportionately longer nose gear, it did present additional operational considerations upon recovery, and I'm thinking the Piper Commanche here.

I'm thinking more of something that raises out of the groove on the deck and which a normal length nose wheel can be firmly placed and secured on. Can make it retractable or lying flat when not in use maybe? Since for most carriers the landing aircraft does not need to use the part of the deck that is reserved for take-offs?

Might be complicated.

This give you a somewhat higher angle of attack at leaving the deck, it doesn't give your velocity a vertical component that would give you more time to accelerate. It proved necessary on the British F-4K in the '60's, but I understand the use was awkward.

The Cubans are bound to defend themselves, just as they did in 1961.

That is a very nice photo. Lots of different colored shirts there on the deck. People are learning their jobs.

Lines up pretty well with my own build of the vessel in 1/350 scale:

PLAN's First Aircraft Carrier

That model is close to 3ft long. Really enjoyed building it.
