Pulse Jet Propeller Thrust Calculation

  1. Dec 15, 2009 #1
    Hello everyone!

    I recently visited the Air Force museum in Ohio and saw their Pulsejet Helicopter. It was intriguing how they attached a pulsejet to the end of each propeller tip. Since then, I’ve been wondering if two pulsejets could be used on a general aviation propeller.

    I’d like to calculate how fast a pulsejet powered propeller could spin, but I have no idea where to start. I got my degree in chemistry, so I’m out of my league here.

    I’ve looked online and found some smaller pulsejets that can output 4 lbs of thrust. If the jets were affixed perpendicularly to the tips of a 69 inch diameter propeller, about what are we looking at? I’m sure there’s drag and all sorts of things to consider, but is there a way to get a rough number?
