Nice find, I know Spaz and I had been frantically searching for pretty much whatever we could find for a few months now (he probably longer)..Interesting that they did this on the weekend, don't know about the Chesapeake Bay but we nearly had a Tornado touch down in Annapolis-Baltimore area on Saturday

Sorry guys, but I've had to remove the video for now at the request of the source; it should be available again soon however.

It has been posted here (not by me):

...shucks, I missed it...but looking back at that photo, I begin to be staggered at the flight control variables that are being computed beyond a (simple??) cat shot! ....errr, am I missing something? :doh:

....how do you keep the "Bee" on the ski-jump?...where do you calculate V2? ...at the bottom of the jump or at the top???...sorry, it's been a long day...

...I am happy to see the photo.. Yay!

...and it's back again and the video explains most of it. The main strut seems to drop about 12" after lift-off (lite-load? (as one might expect?))...thanks again for the video from who ever. Cheers :cheers:

'neptune' OK for your long day - I get that now - IN my timezone it has been a LONG MORNING and I ain't ate brekkie (breakfast) and it is almost lunch time so I'm a bit ornery.... :devil:

Another thread has a long description of HOW the F-35B does the ski jump STO and how the flight computer knows that the aircraft is on the ramp and to keep the wheels on the ramp before going ballistic off it - with the aid of significant wing lift now allowed (not on the ski jump though) and the engine lift. I may find it before I faint from low blood sugar. :drool:

Thanks Spaz, I'll check it in the morn!

For 'bring_it_on'... During a fainting spell I had this vision of the old news about old scheduled JumpDeSki but URL now discontinued so perhaps I'm making it all up? Dunno.

JSF ski jump tests due in 2011
08 Jul 2010 Someone

“'Ski jump' trials of the Lockheed Martin F-35B Lightning II Joint Strike Fighter are expected to take place in 18 months' time at US Naval Air Station (NAS) Patuxent River in Maryland. The tests will see if the F-35B can fly from the take-off ramps to be fitted to the UK Royal Navy's two new Queen Elizabeth-class future aircraft carriers (CVF), but BAE Systems F-35 test pilot Graham Tomlinson told Jane's that he expects such take-offs to be far more straightforward than those from flat deck aircraft carriers.”

JSF programme to proceed with UK-specific land-based carrier trials
09 Jul 2012 Gareth Jennings

“The Program Office for the Lockheed Martin F-35 Lightning II Joint Strike Fighter (JSF) is to shortly commence UK-specific trials for carrier operations of the short take-off/vertical landing (STOVL) variant F-35B, it was announced at the Farnborough Airshow 2012. Speaking on 10 July, BAE Systems lead STOVL test pilot Peter 'Wizzer' Wilson said that 'ski-jump' launch trials will begin at Naval Air Station (NAS) Patuxent River, Maryland, in the near future, while work on the shipborne rolling vertical landing (SRVL) is also ongoing...."

Carrier countdown [MORE of this HERE: viewtopic.php?f=22&t=20304&p=275767&hilit=Robinson#p275767 ]
30 June 2014 Tim Robinson

"...Not your father’s ski-jump
The QE-class’s ski-jump, too, has been carefully designed and engineered from the beginning — drawing on BAE’s Harrier
heritage. Says Atkinson: “We had to go back into the archives and talk to people who had actually been involved with trials with the Sea Harrier and Harrier to make sure we understood the history of ski-jump ramp development. The aircraft carrier ski-jump is a UK innovation and something the UK is very proud of”. The QEC’s ski-jump is longer (200ft) than the Invincible class (150ft) and designed so that the aircraft has all three (including the nose) wheels in contact right up until the point where the aircraft leaves the deck — giving positive nose wheel authority throughout. Additionally, the F-35Bs smart flight control system ‘knows’ when it is going up a ramp and will pre-position the control surfaces and effectors to launch at the optimum angle to avoid pitch-up or down...."

Salute!

I did not see any "ballistic" arc, but more like the STO's from the Wasp.

Any Harrier troops out there to give us a clue?

I always thot the deal was provide an upward vector, unload and get to "wing borne" before coming back to the ground/sea. That sucker or two seemed to just gradually accelerate in that "in between" mode.

Gotta be a STO mode, as the Bee I saw here at Eglin awhile back flew a normal base turn and low approach with all the doors open. After stopping at mid field 100ft alt or so ( hover mode, apparently), it transitioned to forward flight and did a closed pattern for a fairly short landing with all the doors open.

Gums wonders....
