Venera-4 VS Venera-14

I'll be back into addon development in less than a month now, school year is nearly over. Can't wait !

Venera-4 VS Venera-14

Can you do the Mars probes as well? The bus share an identical design as Venera 14's

Looks very cool, I must say I'm not sure how the parachute used for final descent looked like. I know they made it from some kind of metal because nylon or kevlar just melted or burned in the infernal heat... It was learnt the hard way !

We're talking of +460°C, my own small kitchen electrical oven stops at +270°C, and it is enough too make anything from biological origin look completely charred very quickly

Stainless steel mesh, perhaps?

parachute was made of glass-nitron (стеклонитрон) connection nitron with fiberglass this material is found only in a parachute that now lies on Venus

coloring I was inspired by the pictures

I don't think they used the parachute below a certain altitude (don't know what it was, but it was way up), and the vehicle slowed down with the drag of the disk at the top, and landing was cushioned by the disk at the bottom.

Yeah, the parachute was separated way up at 50 km. The atmosphere is dense enough to land "soft" at 7-8 m/s

Venera 11 to 14 had their main buses flyby Venus instead of being destroyed in the atmosphere...however those of Venera 3 to 8 were indeed intentionally burned up iirc

maneuvers are performed by a single engine that oscillates

top cover had its own parachute (since the parachute consists of nitron and fiberglass nitron gradually burned out, the fiberglass lattice remained)

lunokhod and lander were covered with thermal insulation it is very different from the exhibition in the museum but you can make two 3d models


there was also an interface like a modern video game

Museum and realistic version

 

[N_Molson]

The thermal insulation makes a lot of sense. From what I have read, making the Lunokhod able to survive a lunar 14-days night without freezing to death was quite a challenge. In the absence of atmosphere, temperatures plummet to values close from the absolute zero (-273.15°C).

It led to that funny "kettle" design, with the lid closing to keep as much of possible the little heat from the RTG, and the sensitive electronics inside.
