SHINY new LCH4 GSE to support another round of testing- 25klbf & 5klbf engines . This is 1 of 2 under construction. #RocketsGetThirstyToo
3D printed rockets with Dave Masten - Orbit 10.32Published on 3 Sep 2017This week we bring on guest Dave Masten to get an update of the happenings at Masten Space Systems. In addition to an update on the XS-1 project, we also talk about how Dave and crew is using additive manufacturing (3D printing) to create entire rocket engines. Interview starts at 16:59
Broadsword is going to have at least as good TWR as Merlin. Does anyone have an educated guess about ISP?
Can an expendable XL-1 place the landing cradle for reusable XEUS?

The electric pumps are good for up to 5klbs engine, same as Rudiford. I did wonder how big an engine e-pump would drive.Broadsword 25klbs engine use two turbopumps one LOX and for methane.
Putting Merlin to shame T/W-wise......since Merlin is about 180-200 T/W on the dev-side, might they be talking 250-300? That'd make a fantastic SSTO engine.
If you address the minimum gauge issues with smaller engines using better manufacturing or design tricks, then in principle a small motor should get higher thrust to weight than a large one until minimum gauge issues bite again.
