Welcome back!In the last two posts, we’ve introduced you to the first steps and calculations of how to calculate mission specified propulsion system parameters. We know it’s been a lot of information so, thank you for sticking with us!Let’s start with designing the other subsystems that facilitate the accurate functioning of the satellite propulsion system....

In the last post we’ve left you with the thrust calculations but did you think about the condition Pe=Pa? And that the thrust is maximum and the nozzle is said to be adapted? This condition is called optimum or correct expansion. At high-temperature, flow is exhausted and it expands against the walls of the nozzle...
