Salute!

I can't find a good dimensional diagram of the A-7D hook distance, but it looks like about the same distance as the A-4 from mains to hook shoe.

Our hook was the same as the Navy version, and not the spring-looking thing depicted above for the "A" model. We also retained the wing fold and such from the Navy design.

WRT to the donuts..... Seems to me that the donuts cause the wire to bounce back up quickly after the mains pass over. The ones depicted for the boats would seem to allow the wire to slide forward and may not get back up high enough for a short hook to engage. But what do I know? Only had one skip outta three attempts, and was below flying speed.

When I get the next tour at Eglin, I'll get better pics and talk about it with the pilots and crew chiefs. We should be flying within the next month, according to the Wing king and others there yesterday.

Gums, Thanks. As the thread here suggests [http://www.f-16.net/f-16_forum_viewtopic-t-15767-start-120.html] the arresting systems are chaotic [http://elementsofpower.blogspot.com/2012/01/f-35-tailhook-risks-meh.html] (and different as you suggest).

What the F-35C hook redesign will do (which will then more closely resemble the F-35A hook and the A-4 hook) is enhance that ashore 'rubber grommet held up' arrestor wire catching and also the 'land based test onboard current USN flight deck gear system' at NAS Lakehurst. It will take the test results to show one way or tuther. I just don't leap to silly conclusions ala elp/Goon et al.

And a lucky last almost 'taxi 1' wire showing some possible A4G trampling but then again perhaps the wheels have hit the deck just after the no.1 wire - dramatic photo by Laurie Hillier nevertheless (CAA - Chief Airframe Artificer [overall in charge of maintenance and in effect the squadron) of VF-805 in the late 1970s. The chap to whom one says: "Not me Chief". Very Happy

The new F-35C hook design will enable a better pickup of trampled, or flat on the deck or runway, arrestor wires.

The reprofiled F-35 hook point looks alot more like the SH point then the one that failed the wire engagment tests.

The Growler is one of my squadron jets too.

navy_airframer I think you are missing something. Have a look at this graphic: http://www.f-16.net/attachments/f_35cho ... ig_145.gif
from 8th page of this thread: http://www.f-16.net/f-16_forum_viewtopi ... t-105.html

If you have a photo or drawing of a Super Hornet and / or a Hornet hook point to share that would be terrific. Thanks.

And this graphic is incorrectly attributed to the QLR PDF which actually does not have the hook series so the one to download is POGO at: http://s3.documentcloud.org/documents/2 ... report.pdf (19Mb)

@Spazsinbad..... I wonder if some one bothered to figure what the minimum radius they can get away on the front of the hook. One would think the less radius the better as you get more a spatula effect.

I think LM/NavAir/B&SS have this in mind.

According to this graphic the diameter of the 'Cross Deck Pendant' displayed on left of above graphic is 1 and 3/8ths of an inch OR 1 and 7/16ths of an inch.

Spaz, is there anything to preclude use of grommets aboard ship? They would seem to do a good job of elevating the cable off the deck.

IMHO the wire supports do a great job. Any deck hardware must be just that - hardwearing. The rubber grommets are for sometime use in the nevernever. There just in case. I don't know how long these rubber thingies would last but I guess they are replaced every now and then. I guess we need to see a slomo grommet arrest ashore to see what happens to them. Very Happy

Grommet is an Oz Surfer Slang term for a newbie. Especially an annoying one that gets in the way of real surfers. Very Happy

Another issue for friendliness onboard is that the wire supports go flat as do the wires when otherwise not in use. It really is no fun to be around the wires when they are UP!

Yup, those rubber rings would probably get shredded in no time in a carrier environment. Threading cable thru replacement rubber donuts won't be any fun either.

popcorn surmises (very well indeed) Very Happy

"...Threading cable thru replacement rubber donuts won't be any fun either." As I recall there is some Naval saying about 'rolling donuts' and 'flying something or others'? Very Happy
