Title: Over-The-Nose Visibility
Post by: KJ_Lesnick on July 15, 2010, 06:58:49 PM
It's an important quality for Carrier-Based aircraft, but I'm wondering what Air-Force Aircraft meet the criteria the US Navy require?  Also, are there any US Navy Aircraft that do not (The F8U-3 and F-18A don't look like they would do too well)

I would say the A-7, and the A-10 - probably the Thunderbolt II would be the best carrier plane, for visibility.  Also, the C-130, great over nose visibility, and proven capable of carrier landings!

It's not just a question of the shape of the nose, it also depends on the angle of attack on approach. I'm guessing that the F-18's FBW system and aerodynamics allow it to make a slow-enough approach at a reasonable AoA. Were it the same shape(ish), but with 1960s technology, it might have more of a problem. Also, remember that a USN F-18 is a relatively small aircraft on a VERY big carrier, so it can probably afford to come in hotter and flatter than it would on, say, the Charles de Gaul.

     Well, since the A-7 was already a USN a/c.......

I was rather thinking of the USAF A-7D, built especially for them.....
Besides, the A-10 would make a good carrier plane - low approach speed, strong u/c, good range, manouverable, heavy firepower, low maintenance....

One wonders how the Rafales fares in that regard. They seem to land with a very high angle of attack. :o

Actually, they'd have to ask the carrier to slow down a bit. At top speed, the carrier would probably outrun the A-10. :lol: I think someone (probably an Eagle or Viper driver) on ARC remarked that the A-10 is the only aircraft to have suffered birdstrikes from the rear.  :wacko:

No, I'm sure the Caribou suffered that indignity on a regular occurrence! ;D

Yeah, but then again, that was a wanted feature (the slow speed, not having birds fly up the exhausts  :wacko:) of the Caribou. Hence my idea to use them as COD planes for the helo pads of cruisers and destroyers. :lol:

Harrier.  RAF, rather than USAF I suppose but it would more than meet all requirements for deck landing of course.

The F-15 doesn't have much worse a view than the F-14 & a naval F-15N was proposed.

Makes sense as they're used off carriers

Instinctively I would agree, but I remember hearing at least once that it wasn't quite sufficient, maybe this was simply an excuse by the USN to prevent the F-15N from entering service with them, but who knows?

Wasn't it's original role though, the VTOL requirements just lent themselves to carrier ops

Truem but then again, they have a rather shorter nose shape than the F-18 that Kendra was talking about, so maybe they're geometrically better?

Somewhere in a book I have an A-10 pilot's first solo certificate, which features an excellent caricature of the aircraft with kitchen sinks among the underwing ordnance, tank-style rivets all around the cockpit "bathtub", "Acme Cement" on the engine nacelles and a bird flying into it from behind..... ;D

The F7U Cutlass landed at an extremely high AoA, in fact so high that they couldn't even see the deck (at all).  Yet the nose wasn't that abnormally shaped
Title: Re: Over-The-Nose Visibility
Post by: PR19_Kit on July 20, 2010, 02:50:11 PM
But they changed the shape of the nose of the Cutlass radically between the original  F7U-1 and the -3. The -1 has a relatively conventional cockpit position but the -3 had a much higher one and it was moved further forward I think. Either that or they shortened the nose itself.

The F7U-3 cockpit was raised up, leading to the big fairing behind it, and the nose shape was changed from a pure cone to something like an A-4 profile to make the angle of it's upper surface more steeply sloped.

Weaver,

QuoteThe F7U-3 cockpit was raised up, leading to the big fairing behind it, and the nose shape was changed from a pure cone to something like an A-4 profile to make the angle of it's upper surface more steeply sloped.

And these modifications were sufficient to allow them to see the deck during landing?
