JoeSchmuckatelli Posted November 9, 2022 Share Posted November 9, 2022 They say they will use a sea level nozzle for testing and then replace with vacuum for flight... Is that common? Quote Link to comment Share on other sites More sharing options...

Is that common? I imagine their vacuum nozzle just isn't capable of operating at 1 atm, which makes sense Quote Link to comment Share on other sites More sharing options...

AckSed Posted May 21 Share Posted May 21 (edited) Totally missed this earlier, but EA has a new video comparing and contrasting RFA and ISAR, another startup. Tl;dw RFA takes advantage of automotive suppliers and a cost-optimising expert system to have components tweaked and supplied for a tenth of the cost from aerospace supplier, while ISAR is a near-full-integration vertical: https://www.youtube.com/watch?v=LRFnGnJzRJQ Honestly, RFA seems to have this: they build cheaply, build cleverly and outright state that they have to be profitable or they'll die. Edit: However, as a rocket propellant nerd, I like that ISAR is not only using propalox, but also cooling the chamber and throat with the LOX, with the propane cooling the nozzle.
