New X Plane: Lockheed Martin X-56 MUTT (Multi-Utility Technology Testbed)

[Whisperstream]

So, that's both X-56 air vehicles lost now. The first one crashed during takeoff on 19 November 2015.

I wonder how this will ultimately effect the Northrop Grumman sponsored research effort.

The X-56A lies on the lakebed following a landing accident involving the interaction of the aeroelastic wings and
the landing gear. It came to rest on its back and burned. The aircraft lies in a puddle of fire suppressant foam.

That should buff right out.

Interesting X-56A configuration with a beaver tail in CalPoly Pomona's Subsonic Wind Tunnel

When the aircraft touched down, did the flexi-wings bounce, changing shape fast enough to beat control loop and flip the rig ??

IIRC, one of the thin-winged 40s/50s US designs suffered from 'reversed controls' due to excessive flexure...

A number of the '50s era fighters had that issue (F8U and early F-100s as an example) , hence the inboard ailerons and in some cases (F3H), added spoilerons.

The model was built by a team of students at the University of Arizona. It was called X-56 Dynamically-scaled Aircraft for Research and Testing (DART). The project team was tasked with creating a half-size dynamically scaled working model of the X-56A Multi Utility Technological Testbed (MUTT).

The team also created a straight wing version of the aircraft that initially looked a lot like the QUARTZ Advanced Airborne Reconnaissance System UAV concept. For improved stability and control, however, they added a T-tail that gave the airplane a more conventional configuration.
