A bit of hype in the title, but interesting none the less.

Remotely Piloted PTERA Bridges Gap Between Wind Tunnel and Crewed Flight-Testing
On October 22, researchers from NASA’s Armstrong Flight Research Center at Edwards Air Force Base, California, and Area-I, Inc., of Kennesaw, Georgia, successfully conducted the maiden flight of a remotely piloted test bed for cutting edge aviation and space technologies. The Prototype-Technology Evaluation and Research Aircraft (PTERA) is a versatile flying laboratory bridging the gap between wind-tunnel experiments and crewed flight-testing...

Hi,

NASA spanloader cargo aircraft.

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19900004900_1990004900.pdf
~5% static margin during landing and they thought that was okay for a potentially non fly-by-wire aircraft? For perspective the UN-stable Formula 1 air racers have a static margin similar to this and are a real handful.

80% drag reduction with active laminar flow control with that thick of an airfoil at Mach .75?

Plus all the other specs paint the picture that a normal tube and wing config would be more efficient in all aspects.

1977, eh. They were assuming (correctly) that there would be another oil crisis in the near future, not to mention the already high extant oil prices. Pity this wasn't proceeded with. I wonder if there was any USAF interest in this for REFORGER?

No idea, the study concluded that the idea was economically marginal and one of their hopes was that the military would become interested enough to take the study to the next stage (Eg Wind Tunnel testing and hopefully construction of flight hardware...)

Evaluation of effectiveness of various devices for attenuation of trailing vortices based on model tests in a large towing

The effectiveness of various candidate aircraft-wing devices for attenuation of trailing vortices generated by large aircraft is evaluated on basis of results of experiments conducted with a 0.03-scale model of a Boeing 747 transport aircraft using a technique developed at the HYDRONAUTICS Ship Model Basin. Emphasis is on the effects produced by these devices in the far-field (up to 8 kilometers downstream of full-scale generating aircraft) where the unaltered vortex-wakes could still be hazardous to small following aircraft. The evaluation is based primarily on quantitative measurements of the respective vortex velocity distributions made by means of hot-film probe traverses in a transverse plane at selected stations downstream. The effects of these altered wakes on rolling moment induced on a small following aircraft are also studied using a modified lifting-surface theory with a synthesized Gates Learjet as a typical example. Lift and drag measurements concurrently obtained in the model tests are used to appraise the effects of each device investigated on the performance characteristics of the generating aircraft.
To cut to the chase, winglets mounted on the underside of the wing proved the most effective at reducing vortex generation, but nothing prevented the vortexes from being dangerous 4.5km behind the aircraft.

I sent like this idea in aircraft design from my creation to Boeing company from more than 6 years ago.

They seem to have, like a lot of the youtube video's, an unhealthy fixation on musical accompaniment. It is soooooo last decade, peeps.

Amazing concept,I did something like this but differed a little from my creation,

IMHO a study model of a NASA experimental high altitude research aircraft. It is probably powered by two (or one) turbocharged piston engines and features an extremely long span wing.

I suspect some of those designs are part of NASA's collaboration with Cranfield University in the UK, though the pdf doesn't mention it.
