A domestic space engine with 360 tons of thrust in a single chamber has arrived.

　　Now our official announced that we would develop the single-room 360, and saw a friend invite out the F-1, the strongest single-room liquid in history, for sacrifice. Saturn V's F-1 is an ancient god beast, and it is also true that the 680-ton single-chamber push is invincible so far, but it can be said that it is of no reference value for us to engage in large-thrust kerosene engines now. The F-1 adopts the traditional gas generator cycle, without secondary combustion, with low efficiency and low fuel consumption, and the technology is outdated. The old horse can grow old trees and sprout new buds, and it is really awesome to play as it is now. We are taking the road of being an engine, and now the main YF-100 has been in a hierarchical cycle, so it is impossible to go back.

　　The reason why Laomei only made one F-1 in the field of kerosene engine is because it has never been able to overcome the problem of "coking in the combustion chamber": when the pressure of the combustion chamber is greater than 7mpa, the inner wall of the injector disk will agglomerate and block the fuel pipeline, and there is only one result: explosion. Therefore, even if it is as powerful as F-1, it can't cross this hurdle, and the combustion chamber pressure is finally fixed at 7mpa. On the other hand, the value of Russian RD-170 is 24.5mpa, which is three times as much as that of F-1. Even the YF-100 of rabbits has a chamber pressure of 18mpa.

　　Of course, now we all know that coking is caused by too high sulfur content in kerosene, and sulfur removal methods are quite mature today, which is not a problem. In the future, we will make a single room 360, and the room pressure should be at least close to RD-170, which is a great challenge. As also analyzed in the previous article, the combustion chamber area of YF-130 is much larger than that of RD-170, but the specific impulse is much lower, which is caused by the low chamber pressure. I wonder if the proposal of YF-135 has anything to do with it.

　　In other words, the United States and the United States also tried to solve this problem, but at the time of the US-Soviet moon race, there was no time to calm down and do in-depth research, so we had to adopt a temporary solution instead of a permanent solution: sharing the pressure of the combustion chamber by increasing the nozzle area, which is the origin of the unprecedented huge nozzle of the F-1. America knew the limitations of the F-1 and quickly abandoned it after landing on the moon. It seems that we are now in a new round of race to the moon, so it is inevitable that we will not follow the old road of no hair, and we must never follow the road that America made the F-1.
