Re: What was this glider ?
Interesting. The wing form makes Tikhonravov's much later I-302 rocket fighter design look tame by comparison.

"During his third year at Zhukovsky Academy, Tikhonravov along with V. S. Pyshnov and S. V. Ilyushin (future famous aircraft designer) organized a glider club under auspices of the Military Scientific Society. Within the club, students developed their own glider designs, which would be built at the academy workshops. Tikhonravov's glider dubbed AVF-1 "Arap" was built first. It was the only glider of the Academy, which passed the 1st All-Union glider tests in the fall of 1923 in Koktebel, Crimea. In 1924, Tikhonravov became a member of the Technical Committee overseeing glider testing. In Koktebel, the home of Soviet glider enthusiasts, in 1927, Tikhonravov met Sergei Korolev, who was also starting his career on the wings of gliders. They became friends and colleagues for decades to come and... made history in process."
