The amount of heat transferred by conduction is small and the amount transferred by radiation is usually less than 25%, of the total. The chamber walls have to be kept at a temperature such that the ... WebMar 5, 2024 · The RS-25 nozzle has an unusually large expansion ratio (about 69:1) for the chamber pressure. [13] At sea level, a nozzle of this ratio would normally undergo flow separation of the jet from the nozzle, which would cause control difficulties and could even mechanically damage the vehicle.
‘Fire in the Hole:’ NASA’s Stennis Preparing Stand for RS-25 Testing
WebThe point is that the RS-25 has to accommodate a very wide range of inlet pressures while maintaining a set thrust level and engine mixture ratio. While this has always been the case for the SSME/RS-25, the longer SLS vehicle configuration simply exacerbates the situation. You’ll note that I’ve not talked about the liquid hydrogen here. WebThe RS-25 is designed to go from sealevel to practically space (if i am correct), so i guess the nozzle is designed for like 0.5 atm and thus the ambient pressure at sealevel is to high … how to make 10000 a month on youtube
