Lockheed Martin F-35A, B, C and other ideas

They've built a HUNDRED of them already?

Yep.  There was a real neat lineup of F-35Bs at Eglin for VMF-something in one the the recent aviation magazines on the stands.

Cheers,

Almost  . Designated to be the first Luke AFB F-35. I like the tail flash.

Wonder when we will get the Peppermint Primer in model paint as we have the Zinc Chromate previously used, so somebody is bound to do that pale green eventually. Would make a great model in the roll out scheme before they get to the paint shop

I've got a Pactra or Testors paint about that shade, used for custom car stuff, and I think it's actually called Peppermint too!

First night STOVL from a ship (the music is weird  )

Some interesting points there.

In the daylight shots they're landing with the weapons bay doors open, I wonder why? And in the night take off he only translates the aft nozzle to half deflection just before he reaches the bow, otherwise it's pointing more to the rear. That needs some precise timing for sure.

The weapon bay doors are probably open as LID or Lift Improvement Devices to help form a cushion of air beneath the fuselage.

I thought the nozzle was set at the same angle for the rolling take off.

In the vid you can just see the reheat flame vector downwards a bit more as the aircraft approaches the end of the deck. The equivalent of a ski-jump on a UK carrier perhaps?

Kit, it seems to me that the noozle is vectored down slightly right from the get-go, the flames appears to be hitting the deck right from the start and then appears to be vectored more at just before take-off, but that could be attributed to the rotation of the aircraft ---

That's exactly what I meant.

It starts of with around 30 deg deflection, it'd have to have SOME horizontal component or it wouldn't move, and just as it reaches the bow it angles down more. It's difficult to see as it's dark but I thought the nozzle moved relative to the airframe some.

Good link thanks.  I had the pleasure of being at Patuxeunt River Naval Air Station a few months back and there were two B models flying that day.  BF-3 taxied right past me with dummy sidewinders on the outer wing pylons.  Another was doing touch and goes, with heavy side to side rolls on approach- rocking back and forth with about 30 degrees down each wing. Very impressive. All landings were rollers at about 50 knots.  The "barn door" cover over the lift fan is indeed huge.  I can testitfy they defintiely meet the airshow crowd pleasing decible levels on takeoff!

I believe the F-35 flight logic will automatically adjust the rear nozzle angle for the deck takeoff, so no need to have a nozzle stop set like in the harrier/sea harrier, where the pilot has to time the precice time to bang the nozzles down to ~50 degrees when nearing the end of the deck.  So perhaps when the pilot rotates for launch the rear nozzle adjusts?

That makes a lot of sense, yes.

The control system for the F-35, developed on the Harrier T4 at Boscombe Down, would do that with the test aircraft and it flew a total mission, from engine start to shutdown, with the pilot operating 'hands off'.
