The Chongqing University Industrial Technology Research Institute has flight tested a prototype rotating detonation engine on a scale model plane. The engine is designated FB-1.

Interesting, especially why testing it in / under a Su-34look-alike scale model?

There's probably no significance to it, and likely was just a model that they happened to have lying around that was available.

As we can see the engine itself isn't even integrated in the airframe nacelle, but rather strapped under it.

Yes, but why a Su-34 shaped one? We know China knows all about the regular Flankers and even if we know they tested several other platforms in wind-tunnels or like this one, I'm at least surprised.

They probably have a bunch of air-worthy subscale models of a variety of different aircraft both domestic and foreign, because they probably have done testing for a number of domestic and foreign airframe designs as part of routine academic investigation.

The question probably shouldn't be "why Su-34" but "why not Su-34".
