Actually it gave validity to post stall super maneuverability and used a layout similar to the EF. Without constant nose corrections it's nose would flip up and over instantly.

Isn't this almost a spitting image of it ?

well the Chinese did get an extensive look at the Lavi

then they made their own in the early 90s

but had to modify the design extensively because they could only get Russian engines.

this just looks right

J-10 flew 1998 https://en.wikipedia.org/wiki/Chengdu_J-10 and IAI Lavi 12 years earlier 1986; https://en.wikipedia.org/wiki/IAI_Lavi

So you are right.

Actually X-31 flew in 1990 and Eurofighter 4 years after; https://en.wikipedia.org/wiki/Eurofighter_Typhoon

I figure J-10 and Typhoon can supercruise.

When was the original concept first introduced/patented ?

Instead of super maneuverable fighter someone should design VLO light interceptor (composite sledge no need to tolerate high g's) what is designed to carry 3x BVRAAM's as it's armament. No cannon since it would only add weight.

It would be beautiful like F-104 Starfighter.

Might be....the FSX model was pretty easy to fly at 10 kts speed 70 degs nose up.

One thing bugs me...the X-31 goes 1.28 M but similar engine Gripen Mach 2.0 ?

Why does the X-31 have cranked-delta wing ? Does that cause the stability ?

What are those underneath the wing ? ;)

Who cares ? It was a research craft in the field of supermanoevrability. Why would they bother design an inlet that works up to Mach 2 ?

As said earlier, actuator fairings.

Right it was not designed to go any faster.

Did see one of the X-31's demonstrate at Le Bourget once. Was impressive!

Frontal area? Think F4J or F4M...

It was an experimental aircraft so no requirement for bottle shape area ruling.
