Conventional turbopumps are fiddly to design, complex, somewhat unreliable/dangeous. On the other hand they have an extremely high power/weight ratio. But there's significant work in building one.Just got to wonder... lots of talk about how difficult it is to built reliable and efficient turbo pumps...
Two 'amateurs' have made pumps that I know of:lots of good intentions to experiment...
But has anyone ever succeeded in building a small-scale pump suitable for amateur use, and who would be willing to share anything from a rough sketch to a detailed blue-print?
- the www.flometric.com pump
- John Carmack built a rocket powered helicopter style rotor with considerable pumping capability; it's a similar concept to the Rotary Rocket pumping technique
There's also the reciprocating piston pump that XCOR are working on based on the Astrid pump concept.
