MIXED FLOW PUMP DESIGN
MIXED FLOW PUMP DESIGN
(OP)
I am looking for some info. on mixed flow pump design.
I would like to predict input requirements as well as output performence before moving to the prototype stage.
I am working at designing a lower hp (15 hp) outboard motor jet design instead of traditional propeller.
Jet configuration is nothing more than a centrifugal screw pump with 3 blade impeller configuration instead of single blade.
Presently all outboard motor manufactures are purchasing their jet pumps from a supplier in California, which is not interested in manufacturing for lower horsepower engines.
Any help ould greatly be appreciated

Thank you for taking the time to answer.
I will do so.

Sorry I can't give you any reference to it but at the time it was well documented - if you are going to search for it look for the name "Squid" - from memory this is what he named it.

Thanks for the reply.
Do you know if this was done on a outboard motor or was it inboard type like the axial jets used today on watercrafts and boats?

Sorry I can't be more specific - but at the time I wasn't all that interested in it - just remember reading an article about it which would have come from a USA boating magazine.
Thinking back it was probably more like 30 years ago not the 15 / 20 I said originally.
