Northrop Grumman X-47B UCAS-D

You are right! Your reach higher effectiveness of the spoiler for directional stability, when it is already partly deployed and has low effect in seperated flow. And can be than faster deployed fully, where it has the higher effect.

Interesting!...wouldn´t it be more effective to use wingtip "airbrakes" like the A-6 intruder?

...or like on the B-2. Yes it would, but the question / trade off is also where to put the other control flaps.
 
From the first flight at Pax.

Looks like they did better than Brand-X! At least so far.

::)
 
What sorts of flight control system is employed on this vehicle?
Is it stable aerodynamically?
 
I would say it is statically stable. Center of Gravity in front of the Main Landing Gear and the Neutral Point of the wing behind it!
 
lower left bird looks familiar, no? ;)

The X-47B Unmanned Combat Air System (UCAS) demonstrator successfully completed its inaugural land-based catapult launch Nov. 29 at Naval Air Station Patuxent River, Md.

The Navy's first-ever steam catapult launch of the pilotless X-47B ensures the vehicle can structurally handle the rigors of the unique and stringent aircraft-carrier environment. Read more at: http://www.navair.navy.mil/index.cfm?fuseaction=home.NAVAIRNewsStory&id=5199

First arrested landing (on land)

"X-47B makes its first trap on land"

The US Navy's Northrop Grumman X-47B Unmanned Combat Air System-Demonstrator (UCAS-D) made its first shore-based landing using a carrier's arresting gear system on 4 May. This first trap is the beginning of a series of tests before the X-47B makes its way onto the boat later this month.

"It moves us a critical step closer to proving that unmanned systems can be integrated seamlessly into Navy carrier operations," says Capt Jaime Engdahl, the Navy's UCAS program manager.

Carl Johnson, vice president and Navy UCAS program manager for Northrop Grumman, says, "The X-47B air vehicle performs exactly as predicted by the modeling, simulation and surrogate testing we did early in the UCAS-D program."

For the arrested landing, the X-47B used a navigation approach that closely mimics the technique it will use to land on an aircraft carrier underway at sea according to the Navy.

Hey we are filming history let's capture the guys waiving their hands around and not the UCAS geez Louise :eek:
 
It was that deck crew who made that history. Well done US Navy, well done
