Re: [PSUBS-MAILIST] bionic propeller



Never heard of 'em! Some kind of flow-adaptive contraption?

Keep in mind that "ordinary," pedestrian propellers get very high efficiencies at design point, and wake-adapted propellers can be over 100% in propulsive (not propeller) efficiency with respect to the free stream. There isn't much room for improvement...

that they are more powerfull than normal propellers and very expensive
but I want to know if somebody knows them first hand and confirm or not
if they are so wonderfull as stated.
