Think about phase change cooling for 90 seconds and all the problems it
mitigates. LOX/Kerosene circuit. We did really didn’t have to get that cold but
were able to move a lot of heat in a short period and in a small space using a
simple expander. I guess I wasn’t convincing enough,

So is the aluminum tankage and many other materials just not pyrophoric.
Kerosene is also a good coolant, enough to cool the engine regenerativly.

Rare earth magnets are reasonably flammable in LOX. Really pretty fire though,
beautiful showers of sparks. On the test stand, be sure to shut off the flow of
LOX to the pump if it stops unexpectedly.
I won't impugn the complexity of getting the pumps working well, even if it's
one of the more straightforward cycles. It's very much in the "devil is in the
details" part of engineering. Hopefully PSAS will continue their electric pump
project and share details on how the engineering goes.

The pump looked quite common to me, just a spindle motor and a shrouded
inducer-impeller. Nothing new really.
They ran the prop through the motor for cooling, that’s not new either. Might
be scary with oxygen the first time.

I doubt their pump design is anything but rocket science, low pressure
centrifugal pumps for bi-prop rocket use were used by Robert Goddard and
Germany
back in the 1930's. It's the modern use of rare earth permanent magnet motors
that is unique, something I researched 10 years ago but got no one's attention
in,
i.e.The Rocket Racing League.

After looking at the patent, Peter Beck is the lead name i.e. Rocket Lab.
To me this looks like a design patent. If I 3D designed & printed a different
engine, I would patent the design. The Rocket Lab design looks reasonable but
nothing special. What I would love to see is a design patent on their pump
system.

Interesting diagrams, surprisingly weak claims.
