Greetings,
Has anyone looked at the
XR-40 engine that the Phantom guys are testing? http://www.rotary-xr40.com/
As I understand it, these are go kart engines that normally run up to 10,000
rpm, and make about 52 HP. For aircraft use, they are derating them to 40
HP at 7600 rpm.
I'm not in the market for
this, but I noticed in the FAQ that they don't have a pressure feed oil
system. Instead, they use roller bearings, and 50:1 pre-mix. That
would sure save some weight, and complexity. Has that ever been done on
other rotary engines?
Cheers,
Rusty
