Hence I surmise that the umbrella-like design, described by Perminov , was not the final design for the 5M descent apparatus. Is that right?
 In this stage, the headlight was replaced with a conical aeroshield cover, which was like an umbrella and had a diameter of 11.35 meters. The center was a solid part of the cover with a diameter of 3 meters, into which the thick, tube-like beryllium spokes were installed. The spokes were covered with fiberglass. Before the spacecraft was launched, the spokes were folded along the lander's axis. After the spacecraft would be injected into an interplanetary trajectory, the spokes would be opened to create the aeroshield cover. [p.73]
