Yattaa does mean as much as Yippeee and more like "I have done it", i have made the decision, i am going to Japan next year, 3 weeks, finally. As for the engines, they are the so-called closed-cycle engines wich are more efficient than the open-cycle engine wich just waste precious fuel in the bre-burner wich drives the pumps and then throw it out. A closed-cylce engine leads it to the burning-chamber thus giving it a higher efficiency, the problem is that it also leads to higher pressures and temperatures (especially with a Hydrogen/LOX fuel, the N1 used Kerosene/LOX), if the engine does not work properly it could simply melt or explode. You can solve that problem partly by keeping the engines smaller, but you need more of them, and N1 had 30 engines (as to the Saturn V who had only 5 big open-cycle engines) in its first stage, an enginering nightmare especially since the chief-designer Korolev died in 1966. Take a look on Astronautix, great site about spacetravel and space-history, and a giant resevoir with resources and ideas. http://www.astronautix.com/articles/thepart1.htm For the N1-story
