How to calculate the thrust of a propeller

Web16 jul. 2013 · Answer: using the equation above, the propeller is producing 1619g, 1.619kg, or 3.57lbs of static thrust. Download the spreadsheet above to change the values for your application. At what airspeed will it produce zero thrust (ie: what is it's max thrust-producing airspeed)? Answer: ~60mph. Web29 dec. 2024 · Propeller's diameter 1m and 40° twist@¾ span. Cruise speed 60m/s. J = 60 33 = 1.8; from the plot we get a relevant η = 0.8. So: at 0speed thrust is ⅔ ½ 0.48 × 3 ′ 000 ⅔ ½ π 3 = 116 N at 60m/s it is 0.8 3 ′ 000 60 = 40 N Between those two speeds thrust can be simply linearly interpolated.

If the prop has no slip (unrealistic, but provides us with a starting point), the boat speed would be 16.5 m/s. The advance ratio above neglects slip, so the real value is maybe 1 (more for a lightly loaded prop and vice versa). 20% slip would reduce speed to 13.8 m/s. mice chirping https://markgossage.org
