The Akademiya Vozdushnogo Flota – Air Fleet Academy ( AVF / АВФ ) was an body set up for budding glider (planer) designers during the period 1923-26. Most of the designs appeared at the annual All-Union Gliding Competition (VPI) held at Koktebel (Feodossia) in the Crimea. The majority of the designs remained one-off but a number of well-known Soviet aircraft designers cut their teeth with the AVF.

Hi all!
Here are AVF-27 Vladimirsky Pioner (the world's first full-metal glider, according to Krasilschikov) and AVF-30 KiK photos, both from Krasilschikov book "Gliders of USSR". The man in AVF-30 cockpit is its designer, Anatoly Sen'kov.

By the way, the "Transkaukasier" (in Russian it is named Zakavkazets /Закавказец) is NOT an AVF design. This glider was designed by Alexander Chesalov by the order of Transcaucasian Osoaviakhim section. In August 1925 it was sent to Germany with Soviet team to participate in 6th Rhön gliding contest (together with Kiev-built KPIR-4 and three AVF gliders - AVF-21, 22 and 23) - therefore the name is written in German. The Zakavkazets was piloted by Leonid Jungmeister and took 1st prize for flight endurance among single-seat gliders - 1 hour 45 minutes 16 seconds.
Best regards,
Alexander

Yes: AVF-15 is another designation of Cheranovsky BICh-2. I think many of you recognized it on the picture posted by Maveric.
Best regards,
