didn't they already did a coverage on the x-47b a while back?

Just looked it up, looks like it was first aired 3/26/2008 :-[ Ah well, still has a lot of good stuff. (Didn't realize they were showing reruns, I don't watch it that often.)

(Screen cap whilst they were unfolding the wings.)

Looking at the right, we have the answer about the shape of the engine's nozzle.

Here: (Is it my imagination or is there a suggestion of a flap there at the trailing edge of the nozzle? I've looked the video several times and it's definitely not a video artifact.)

LOL yeah but he does tend to get into the moment a bit much at times.

Apologise friend. That is the NG X-47B demonstrator in assembly. Another poster asked if the exhaust had a flap on it for thrust vectoring - I hoped to show that it appears it does not.

sferrin - best line from "Future Weapons" the stealth episode. A LockMart engineer says about the F-35, "After we leave the battlespace all that's left will be teeth and eyeballs!"

Mack in enthusiastic but he has lived the life so he has walked the walk for sure.

Sometimes it can be useful to simply right-click over the picture and select the image's properties... the name of the picture often contains the name of the model shown (which WAS the case here...). :D

Might be a strap to tie it down on the jig. If it was a flap, would not the hinge line be out of alignment (stealth)?

Yeah, "Race" suggested that as well, and looking at it again I tend to agree with the strap notion.

Yes, he comfortably beat me to it - it's been a long day and I'm somewhat slow on the uptake ;)

The top picture seems to represent a different design from the bottom one. The top design seems a lot like the old Lockheed "Salmon" tailsitter, with equally spaced fins and rudders.

Two Lockheed Martin UAV/UCAV designs taken from a 2002 PowerPoint presentation entitled "Design of UAV Systems". The former has been seen earlier in this thread in lesser quality, while the second one doesn't ring a bell...

Mod edit: image removed/replaced with the higher-res

The former looks like a varient of Sabre Warrior (the tail section is different). I've always liked that one.

When I see that second image, I can't help thinking, "It's VATOL, again!?" Of course, it becomes much more doable without the problems of what to do with the cockpit/pilot position during vertical flight.

Unmanned Systems Alert From Insidedefense.com

Card: Navy Seeking To Dub Next-Generation Unmanned Fighter 'Cutlass'

Inside the Navy, Nov. 15, 2010 -- The Navy wants to name the service's next-generation unmanned fighter and intelligence, surveillance and reconnaissance aircraft the "Cutlass," and the plan is to have a four- to eight-plane squadron on a carrier deck by 2018, Rear Adm. Kendall Card, director of concepts, strategies and integration for information dominance (N2/N6), said last week.
--------------------------------------------------------------------------------------
So "on the deck by 2018" that timeline sure seems to indicate "something" is further along the development stage, than I am aware of anyway.

I guess Adm Card doesn't know that L3 already has a UAV named Cutlass... of course that's a company name and not 'official'

They could choose something a little bit more successful than the F7 "Gutless" Cutlass...unless they are pointing to the fact that the namesake was also a tailless vehicle.

Or it's just rampant optimism. X-47B follow on was supposedly slated for introduction around 2018. It's difficult to see something being introduced by then given the state of play with F-35C. That's actually flying and is only going to reach IOC by 2018.

Moreover, the X-47B can't seem to get off the ground. -SP

The Navy is presumably talking about UCLASS (unmanned carrier-launched airborne surveillance and strike), which is not as ambitious as an X-47B-follow-on UCAV would be. It's what GA-ASI is pitching Sea Avenger for.

But Cutlass - NOOOOOOO! It would be like naming an RAF fighter Defiant.

You may recall that Chance Vought/U.S. Navy named its F7U Cutlass. -SP

Well; I thinl that's pretty much what he meant, Steve. Giving the name of a US Navy fighter to a USAF aircraft would be like naming an RAF fighter with the name of a Royal Navy fighter... ::)

or maybe naming an aircraft after a (sadly) unsuccessful predecessor is not auspicious. I mean, nobody would christen a new liner the "Titanic II", would they?

Well, yeah. But Titanic is a bit extreme an example, don't you think?? LOL
The Northrop Tiger II reused the name of Grumman's F11F, which had not had a very successful career... The McDonnell Phantom II reused the name of its less than glorious predecessor...
