Paul,

Wonder if you have dimension / drawing of 13B Rotor, I want to price it out
for Si-Al Alloy to reduce weight. Thought it might benefit all those who
want a lighter weight engine.

Jeff has the dwgs. He has been working on a titanium version.

What is the working temperature of Si Al?

The rotors run 500 F in some places.

Paul

There is a NASA paper on Si-Al on your website, that answers the above.

450 F TO 700 F is the ideal.
