donwon Posted November 19, 2007 Share Posted November 19, 2007 Since I only worked on the A,s the only thing I know about the 4 blade props is they have one blade more than the 3. Did the newer planes take off and climb out better than the A,s? Did they have as much vibration as the A,s? I have assumed they would cruse faster than the A,s, but I don\'t know.

SEFEGeorge Posted November 19, 2007 Share Posted November 19, 2007 About all I can remember right now is that the 3 bladed props out performed the 4 bladed props at lower altitudes. But at higher altitudes the 4 blades performed better. Quote Link to comment Share on other sites More sharing options...
herkman Posted November 19, 2007 Share Posted November 19, 2007 Yes that statement is correct, up to 18,000 ft the three bladed prop performed better than the four bladed ones. Vibration was also lower. Regards Col Quote Link to comment Share on other sites More sharing options...
herkman Posted November 19, 2007 Share Posted November 19, 2007 OOPS that could be misread, I meant the four bladed prop had less vibration. Col Quote Link to comment Share on other sites More sharing options...
