The Space Cossacks is co-founded by Dmitry Khmara, and he has been talking about how the platform was designed. He said it involves a 3.2m inflatable disk full of helium. The two-ton rocket, according to him, is under an 18m cap, and it takes off from the air at about 20km, after which the disk is suspended. The trajectory of the movement of the rocket is then monitored by the pilot, who positions it orderly. The new prototype that the team is making can remain in the air 10 times longer than the normal copter, and it really amazed the judges including Max Polyakov. The group also won the national stage of the ActInSpace competition in 2018 and showcased their project to people of Europe.
