Summary

DescriptionSsme schematic (updated).svg	English: A functional diagram showing the flow of propellant through an RS-25 engine. Very high flow rates are needed in the main combustion chamber, so the energy to achieve this is generated in upstream combustion "pre-burner" chambers that generate a partial burn to drive the high pressure turbopumps on both the fuel and oxidizer sides. Pressure feeding the preburners is maintained by the low-pressure turbopumps. Routing fuel through the nozzle serves to both cool the nozzle as well as pre-heat the fuel. Català: Un diagrama funcional que mostra el flux de propulsor a través d'un motor RS-25. Es necessiten cabals molt elevats a la cambra de combustió principal, de manera que l'energia per aconseguir-ho es genera a les cambres de "precremador" de combustió aigües amunt que generen una cremada parcial per impulsar les turbobombes d'alta pressió tant pel costat del combustible com per l'oxidant. La pressió que alimenta els precremadors es manté mitjançant les turbobombes de baixa pressió. L'enviament del combustible a través de la tovera serveix tant per refredar la tovera com per preescalfar el combustible. Suomi: Toimintakaavio, jossa esitetään polttoaineen virtaus RS-25-moottorin läpi. Pääpolttokammiossa tarvitaan erittäin suuria virtausnopeuksia, joten tämän saavuttamiseksi tarvittava energia tuotetaan virtaussuuntaan sijaitsevissa polttoaineen esipolttokammioissa, jotka tuottavat osittaisen palamisen polttoaineen ja hapettimen puolella olevien korkeapaineturbopumppujen käyttämiseksi. Matalapaineturbopumput ylläpitävät esipolttimia syöttävää painetta. Polttoaineen ohjaaminen suuttimen läpi sekä jäähdyttää suutinta että esilämmittää polttoainetta.

This SVG file contains embedded text that can be translated into your language, using any capable SVG editor, text editor or the SVG Translate tool. For more information see: About translating SVG files.

This file is translated using SVG <switch> elements. All translations are stored in the same file! Learn more.

For most Wikipedia projects, you can embed the file normally (without a lang parameter). The Wikipedia will use its language if the SVG file supports that language. For example, the German Wikipedia will use German if the SVG file has German. To embed this file in a particular language use the lang parameter with the appropriate language code, e.g. [[File:Ssme schematic (updated).svg|lang=en]] for the English version. Do not specify a lang parameter if it is not needed. The parameter may prevent the use of a subsequent translation.

To translate the text into your language, you can use the SVG Translate tool. Alternatively, you can download the file to your computer, add your translations using whatever software you're familiar with, and re-upload it with the same name. You will find help in Graphics Lab if you're not sure how to do this.
