"This is the QPX-16, the latest Chinese airliner.  It uses solar cells in the nose to provide all the power it needs, while the cabin is so spacious that there are even seats in the tail!

A US Navy F-32 JSF has been scrambled to intercept.

 

Like if you don't want are Navy to harass the Chinese airliner industry just because they've gone past using oil!"

This is the Boeing XB-39:

This was an early B-29 prototype, but the Wright R-3350 Duplex-Cyclone engines were replaced with Allison V-3420s.  

 

What is an Allison V-3420?

 

Why, it's two Allison V-1710s glued together, of course!

Seriously.  That's what it is.  It's two V-1710s glued together.  Was @Oedipus Wreckx-n-Effect an engineer for Allison in a past life?

 

The Germans tried something similar with the DB 610, which was a pair of DB 605 engines paired together to a single output shaft.  However, by all accounts the Allison design worked reasonably well and the Daimler-Benz design did not.  Using the Allison engines in the B-39 would have caused delays, so the Army Air Corps decided to stick with the Wright R-3550.  Switching to the Allisons might have been a good idea, however, the Wright engines were very advanced, powerful and efficient, but they were not very reliable.

 

The V-3420 engine was also used to power the Fisher XP-75 Eagle.  The engine was located behind the pilot, very similar to the configuration of the P-39 and P-63:
