It does have forward sweep
Literally translated, TsAGI is the Central Aerohydrodynamic Institute in Moscow, founded by the pioneer of Russian aviation, Nikolai Yegorovich Zhukovsky on December 1, 1918.
I will accept the project number of this glider as a Tsagi product, but would prefer the name of its designer who led the team who built and flew it and is known for other projects that have appeared on this forum!
