The Dryden X-Press Volume 42, Issue 7 June 2, 2000

Smart Vehicle - Advanced Technology Demonstrator consists of an uninhabited technology demonstrator that will showcase innovative, hingeless aerodynamic effectors that will increase the maneuverability and performance of the vehicle with reduced signature. An advanced autonomous management system will provide health monitoring, fault detection, systems identification, control design, and control allocation and reconfiguration.

This project will be led by Langley with partners Lockheed Martin Tactical Aircraft Systems; Physical Sciences, Inc., Andover, Mass; Tel Aviv University, Israel; Naval Air Systems Command, Patuxent River, Md.; and Dryden.

Re: Lockheed Martin SVATD (Smart Vehicle - Advanced Technology Demonstrator) 200

I suppose wing warping not unlike this one on the first photo, studied by Northrop Grumman in 2003 under NASA 'Smart Wing' program (well, years beforte it was used on MDD Bird Of Prey), but it could be also manipulations with vortex breakdown...many concepts were studied, need to dig more.

Maybe more like....

@ Quellish - Would that be like the Demon UAV flapless flight testing done here in the UK? (utilised blown air instead of control surfaces).

It appears to be a seamless control surface like Bird of Prey, which may allow less deflection than a conventional control surface, and the blown air slat serves to augment it. So for 5 degrees of deflection you may get the same control authority you would with 15. It seems like in this case blown air is augmenting control surfaces rather than replacing them.

Conventional control surfaces cause an RCS spike when used, the B-2 has a "combat mode" which minimizes the allowed control surface deflection and adjusts the flight control laws accordingly - to sacrifice maneuver for stealth.

Initially, the team considered several advanced control effector concepts, including passive porosity,
spanwise blowing, seamless control effectors, inflatable flaps, pulsed jet vortex generators, oscillatory
blowing, wing decamber “bumps,” drooped leading-edge flaps, and reaction control systems. The
team judged each of the foregoing effector concepts (and others) on research merit in terms of
technology readiness level and disciplinary research and development required. The initial control
effector concepts chosen were passive porosity, seamless control effectors, spanwise blowing, and
decamber bumps. Fluidic thrust vectoring was identified as a desirable yaw control effector but was
eliminated to reduce program cost.
