F-35B UK SRVL info - Updated when new/old info available

Salute!

That approach and rollout looks like one I saw this spring at Eglin.

That day we had a three-ship and on first low approach pass one Stubby had all the doors open. I think it ws a VIP demo with all three variants.

Anyway, the basic models landed but the B stopped and hovered, then did a close pattern and did a very short rollout. Had all the doors open, so I am pretty sure it was a "roll on", s the sucker couldn't have been faster than 100 knots on final and turned off about 2000 feet down the runway.

I also think that the great stability when transiitoning to the landing mode is more due to the aero than the FLCS. If it was mostly control laws, then the slab would have been moving a lot more. Atta boy to GD.

There's a lot of effort devoted to suppressing transients between mode switches.

The approach was set using Harrier VAAC no?

By 'approach' can we assume you mean the 'flight control laws' for the F-35B via the VAAC Harrier which (as best it could) simulated the F-35B in STOVL Modes? There is a lot of information about this aspect in this very forum (repeated from other sources of course). Some 'greatest hits': viewtopic.php?f=60&t=52507&p=356421&hilit=Vaac+control+unified#p356421

In this thread a tonne of words: viewtopic.php?f=22&t=20304&p=266824&hilit=Vaac+control+unified#p266824

Elsewhere: viewtopic.php?f=22&t=24054&p=252995&hilit=Vaac+control+unified#p252995

The rest can be found if required by searching. Example: viewtopic.php?f=22&t=24054&p=252995&hilit=Vaac+control+unified#p252995

PDFs about such matters: viewtopic.php?f=22&t=23199&p=247994&hilit=Vaac+control+unified+pdf%2A#p247994

IF interest expressed a PDF about UNIFIED Control Laws may be made or refound as required. CLAW/engine for example:

I meant the "very slow rolling approach". However 'm interested in the pdf.

OK - would be good if you described it easily by 'SRVL' - that is the name of this thread. So there is a heap of info about said SRVL in this thread. Search this thread using VAAC. Good video here: [From about 4 minute mark Justin Paines talks about the VAAC Harrier SRVL development along with CLAW for F-35Bs.] I should except the VAAC bit I guess....

viewtopic.php?f=22&t=20304&p=373976&hilit=VAAC#p373976

Anyway you'll find at least ten more hits using VAAC - just type that term into the search box top left of the page here.

TY. i'll remember SRVL

[spazsinbad]

No worries - are you familiar with 'rockapes'? For them I'll make just an SRVL PDF excerpt from my recent 4.4Gb PDF about the A4G, How to Deck Land and the F-35B/C particularly because they are at the forefront of NavAv on a MAGIC CARPET!

See the link at the btm of my posts for how to get aholt of the humungoid PDF & please follow the download instructions.

A 190 page 'all about SRVL' PDF attached made from a recent 4.4Gb PDF as described above. The SRVL PDF has been reprinted (prn) which flattens the pages and reduces file size however the URL links are lost but URL text still visible.

Pages are a bit jumbled because I got fed up at midnight trying to rearrange them so bear with - be happy but worry.

[spazsinbad]

Found some more SRVL pages to add so now there are 212 - same info as previous post above - new info (posted already in thread) on WIND OVER DECK theoretical measurement with photos of recent actual wind measuring instruments.

SEE NEXT POST BELOW!!!

[spazsinbad]

Had some time to review the SRVL PDF pages - deleted some irrelevant ones and added some more info about V-22 MROL Minimum Run On Landings (very useful for CVN COD V-22s one can imagine) & some stuff about SHOL/SEA STATEs. FINISH.

Repeated the SRVL COMPILATION VIDEO here - because of the SRVL Compilation PDF available for free download above.

[monkeypilot]

Nice one. TY.

[spazsinbad]

No worries. Of course looking through my archive SRVL have found some 'wind over CVF deck sims' that did not make it. I'm working on making PDFs out of them & see if they can be added to SRVL PDF & still be under file limit - probably not.
