Tom22 Posted February 23, 2011 Report Share Posted February 23, 2011 How can I find the flicker frequency of the main rotor for any given helicopter? It’s a good trivia question anyway. Quote Link to comment Share on other sites More sharing options...
AngelFire_91 Posted February 23, 2011 Report Share Posted February 23, 2011 Seems to me if you knew the RPM and the number of blades you could figure it out... I could be WAY off here cause I'm a pilot and not a mathematician but taking the 300 for example. M/R Rpm is ~500, with 3 blades. 500 * 3 = 1500 1500 / 60 = 25hz 1 Quote Link to comment Share on other sites More sharing options...

palmfish Posted February 23, 2011 Report Share Posted February 23, 2011 I decided to run up the AStar this morning to check the formula for accuracy. I woke up 4 hours later in a puddle of my own vomit. 2 Quote Link to comment Share on other sites More sharing options...
