The N1 design

[Bryanpoprobson]

Just a question really probably not really worthy of a thread.

The design of the N1 rocket, the USSR’s answer to Apollo, looks like they were going to use hot staging in the first two stages.

1:- Is that correct

2:- Looking at starship, is there a correlation between multiple small engine designs and the need for hot staging?

As opposed to the large engines used on the Saturn V.

It was seem I was wrong anyway, but most of what we know about N1 is speculation.
While the N1 did have vented interstages, it did not fully employ traditional hot staging as seen in rockets like the Proton or R-7. However, there were partial elements of hot staging involved:

Stage Separation Process:
The first stage fully shut down before separation, meaning there was no direct hot-staging burn-through like in the Proton.
The interstage ring had vents to help with pressure equalization, reducing residual thrust effects.
The second stage engines ignited very soon after stage separation—possibly while still within proximity of the first stage.
Why the Vents?
The vents allowed the second stage to fire quickly without over-pressurizing the interstage area.
This helped prevent backflow of exhaust gases when the second stage ignited, which could have damaged the engines.

No dispute here, but where did you dig up tis tidbit?
