Is it an interesting video other than that?

Paul - I highly recommend that one. It's an information breaktrough on YF-23 made with participation of Northrop/MDC veterans and Western Museum of Flight staff..

*chuckle* I can tell from the technology that those two screen caps show events in the late 1980s since I was  with Northrop, on other programs, at the time.  I've seen at least one other configuration, unfortunately I couldn't copy it, that was a blended double-delta with dorsal inlets that took full advantage of some wind tunnel testing Northrop did on efficient dorsal inlets at high-AOA conditions.

I'm not sure if that ATF-related, as patent refers to PopMech '83 article on 'French ACX'  in chapter named 'Other publications'. Probably El can say if Northrop have some co-operative works with France this time as they have with Germany on ND-102, or it's just cover up. Anyway, on my hard drive these pics are in Northrop ATF folder as well:)

I would say it is definitely ATF related. Everest Riccioni worked with Northrop on defining the "supercruise" aspect of the ATF, in the initial stages. So, this is probably one of the generic concepts studied in the early stages. You can see some relation to ND102 and even the YF-22.

Colonel Riccioni? Probably the most famous F/A-22 opponent?

Overscan, this is Northrop TTLA (Transverse Thrust for Lift Augmentation) concept

What's the rationale for deflecting some of the engine thrust laterally just aft of the wing trailing edge?
