There's a good article on the program in this week's AvWeek.  Basically both companies are working on demonstrator engines sized to fit the F-35, and also have contracts to investigate larger derivatives for 6th-gen aircraft.

Not sure if this picture is a PW AETD engine or not.  The description talks about the level of complexity of the test cell instrumentation and then goes on to say it was used for the adaptive technology development program.  The pipes around the combustor remind me of the bypass arrangement for the PW J58 on the SR-71.

Interesting.  RR also showed pipes in their notional 6th-gen engine design.  Funny that, until recently, all the released artwork has shown the 3rd-stream integrated into the engine case.  I wonder if in this case they just modified an F135 to emulate the effect of a 3rd stream without having to build a completely new engine.  And that the new engine would have the integral ducting of the 3rd stream.

Those are certainly multi-role device:
   - inlet pressure ctrl
   - power generation (Electricity - scalable - this why they are pipes and not con-centrics walls) (+ the added benefice of vorticity break down)
   - Fluidic ctrl at exhaust level and/or  Swirl number ctrl.
