Comment on 3D-printed Aerospike Rocket EngineparentComments−avmich12yThank you. However, turbine exhaust can't provide much thrust - both flow and speed aren't large. So the spike nozzle doesn't get much thrust from turbine gases - yet it can get it from chamber gases.−Gravityloss12yWhich was not my point. Low pressure turbine exhaust gas serves a purpose. Hence the whole name of the engine, "aerospike".It's not very important, it's just names. This project is hardly the first one to not distinguish between spike nozzles and aerospikes.
