Not to nitpick, but the patent is about low observable air intake

Right, but prior art is the DSI bump on a flat surface.

I'm not sure "a DSI bump on a curved surface" is sufficiently novel to be patentable. Because it is a VERY obvious next step from the flat surface DSI.

Also, now that I think about it, IIRC the F-16 DSI was on a slightly curved surface as well...

an LTS of mine for Science. Other than AleDucat i guess no one else making model of LTS's inlet ?

But anyway this is my piece. As seen, I speculated the inlet will be bifurcated until it met the "main duct" somewhere in the middle of fuselage before curving back down to the compressor face. I assume AL-41F1 engine with 932mm diameter.

When modeling the intake did you use the patent as a reference?
