Description
The SF-523 is a light jet fighter from early jet era (between 40th and 50th). Armament consist only from 4 cannon. This one incorporate unique layout - joined wing configuration, that appeared in 70th (but first teoretical prediction by Ludwig Prandtl made in 1924 in his article about induced drag of multiplanes, so some engineers could implement this layout before popularization made by Julian Wolkovitch in his famous paper "Joined wing: an overview" doi.org/10.2514/3.45285)Related content

Reminds me of post ww2 russian designs! Look very interesting!

I built this in KSP, It was a pain in the butt to get a stable flight out of... but I managed it, From what I seen in its performance sadly not a good fighter... BUT, It makes a Very decent High speed Short Range Interceptor.

What about CG position? And angle of incidence for rear wing must be less than in forward wing (1...3 degrees between)

thats not the case in KSP sadly, the rear wing just wasn't producing acquitted lift, and the center of lift made take off a pain.

I don't know, what kind of physics implemented in KSP. If I'll find enough free time, I'll try make this configuration in X-Plane (I have not any doubt about X-Plane physics - there implement true Lifting Line Theory accordingly to L.Prandtl).
I made calculation of aerodynamics coefficient of this configuration in static condition by panel-vortex software some years ago (ieeexplore.ieee.org/document/7… ).

This one resembles some of the "Jägernotprogramm" (Fighter emergency program) of the late Third Reich.
I like it.

This looks rather Russian and late for the Jägernotprogramm considering that, timeline wise, this is close to the end inter-war period just before the cold war.

Both Russians and Americans used technical data gained from experiments of german fighter research.
The MiG-15 and F-86 Sabre do look eerily similar for a reason.
German enigneers were about a decade ahead of anyone else and influenced pretty much any aircraft design until the 60s.
