<VV> Astro 1 engine fans

[BobHelt at aol.com]

Jim, 
Sorry I can't answer your questions, but I can tell you that according to  
the test engineer's report on the Astro 1 engine, the horsepower to drive 
the  fans was just about the same as required for the stock Corvair engines.  
I.e., about 27 hp at 6000 rpm engine speed. Of course belt life will be much 
 better for the Astro setup. So we can see that the Astro 1's fans are no  
more efficient than the Corvair's fans.
Regards,
Bob Helt

the  cooling system was also radically different in that it used three  
blowers
(squirrel cage?) on a single horizontal shaft.  The fan  routing was
simplified to eliminate the 90 degree bends and looks much more  like a
conventional  layout.
