The first thing the engineers began to speed up and facilitate the German design, and achieved considerable success - Rod rose to 51 ton.
But then there were problems of instability of fuel combustion in a large spherical combustion chamber. Glushko realized that it was a dead end and engaged in the development of engines with a cylindrical chamber.
In this field he excelled. In the hands of the keeper of the museum - the first working prototype, which confirmed loyalty to the chosen scheme. What is most surprising - the inside of the combustion chamber - copper alloy. It seems that the element where the pressure exceeds hundreds of atmospheres and temperatures - a thousand degrees Celsius, it is necessary to do from some refractory titanium or tungsten. But it turned out the camera easier to cool, and not to seek unlimited thermal stability. The camera is cooled by liquid propellants, and copper was used because of its high thermal conductivity.
The first development of a new type of combustion chamber were military. In the showroom, they are hidden in the farthest and darkest corner. And the light - pride - RD-107 and RD-108, which ensured the primacy of the Soviet Union in space, and allow Russia to lead the manned space flight today.
Vladimir Sudakov shows steering camera - additional rocket engines, which allow you to control the flight.
In the further development of such a structure has refused - decided to simply reject marching chamber of the engine entirely.
Problems with combustion instability in large chambers until the end to decide it was not possible, so most construction engines KB Glushko - multi-chamber.
