The Cool Video Thread
SpazSinbad:
Here is another HOOK 2014 explanation from the OPNAV N-98 video. This is for the Super Hornet only and there are differences (TWO) with the CARPET for how things are done. I'll guess when testing is finished there will be good explanations about it all.

Just a bit of a recent blurb about SRVL and the SRVV etc.
Stepping-Stones Tony Osborne AVIATION WEEK & SPACE TECHNOLOGY / SEPTEMBER 8, 2014
--- Quote ---"...Test pilots have completed much of the trials work required for the shipboard rolling vertical landing (SRVL), a technique developed for the U.K. to allow the F-35 to land on the ship without having to offload fuel or expensive ordnance beforehand, particularly in warmer regions of the world such as the Middle East.
Trials of creeping vertical landings onto runways at speeds of 10-150 kt. have proven the viability of the SRVL technique, according to BAE Systems test pilot Pete "Wizzer" Wilson. However, the technique now needs to be put to the test on the ship, which is likely to occur on the U.S. East Coast at the end of 2018.
Approach speeds to the ship will probably be 50-60 kt., taking into account the ship's speed and aircraft overtake velocity.
After touchdown, the pilot simply applies the brakes [likely stops within 200 feet according to video below]. Once stopped, the fighter can be maneuvered to its parking position, allowing aircraft behind to land in quick succession.
According to Wilson, the U.S. Marine Corps has expressed interest in the SRVL capability, which would enable operation of F-35Bs from a U.S. Navy carrier without an arrestor hook. "One of the reasons Harriers have never been on board is because of that need to do a vertical landing, which slows the pace of carrier operations," says Wilson. "SRVL could be one way of cross-decking with the F-35B."
The Royal Navy and Royal Air Force expect to do a 50:50 mix of SRVL and standard vertical landings, but managers close to the program anticipate an increased number of SRVLs because they help to reduce the load on engines and thereby increase engine service life.
Deck landings can be performed at up to sea state 6—with waves 4-6 meters (13-20 ft.) in height with assistance from the Bedford Array developed by U.K.'s Qinetiq. The system uses a series of flashing lights located on the centerline of the ship at the landing point. The pilot's helmet-mounted display has a ship-reference velocity vector; by maneuvering the aircraft with vector lined up on the Bedford Array lights, the pilot can make a 6-deg. glideslope approach and landing [starting from 200 feet - approaching that descent point level, slowing down, if need be]...."

SRVL F-35B Demo CVF Sim + extras
GOONIE:
When MAGIC CARPET comes online, what is the pilot going to call at 3/4 of a mile? ???
Pilot:"110, Rhino MAGIC, 6.8"
LSO:"Roger MAGIC!"
that is sad :'(
GOONIE:
Spaz,
Not sure how to edit/clip the tail hook videos, but for those of you interested, here is the PLAT cam footage of the F/A-18E crash behind the boat as part of the safety center brief.
http://new.livestream.com/wab/tailhook/videos/61339809
starts at 29:39, scary stuff :o
SpazSinbad:
I use a screen capture program. I was not sure what was happening in that PLAT/ILARTS clip. Does the aircraft impact the water not far from the ramp? Do you know when that happened?
BTW JPALS will make precise auto landings possible after it is installed and incrementally upgraded. This technology (ship relative GPS) enabled the X-47B to so accurately deck land each and every time. Otherwise the pilot with Magic Carpet still has to move the stick backwards and forwards and side to side as required.
This is how cool it will be when all the bits of the puzzle are in place in a few years:
X-47B Program Update Published on Aug 6, 2013
--- Quote ---"The X-47B Unmanned Combat Air System (UCAS) program demonstrated an acute level of precision and repeatability during at-sea trials this spring/summer. On May 21 2013, the nose gear of the X-47B landed on the same relative spot on the deck of the USS George H.W. Bush seven times consecutively. The success of this at-sea trial, and the proceeding shore-based arrestments were key milestones that led to the X-47B UCAS first-ever carrier arrestment on 10 July."
