| Video Discription | 22 Lego propellers are tested in a water-filled container. Which one provides the most thrust? Enjoy! 2 non-Lego propellers are also tested for comparison. Test method: a Lego Buggy motor (5292c01) and 7V input voltage. A weight scale measures the thrust in grams. Multiple gear ratios (from 1:25 to 5:1) and both directions of rotation are tested for each propeller. The test bench is explained in detail starting at 1:46. Note: the list of gear ratios shown from 3:22 to 3:50 are incorrectly presented as inverse ratios. Sorry about that. The results can be read in my blog: https://brickexperimentchannel.wordpress.com/2024/04/13/lego-propellers-water-thrust/ 0:00 propellers worst to best 1:00 RESULTS CHART 1:46 TEST BENCH 4:22 TEST PROCEDURE 5:44 6041 Propeller 3 Blade 3 Diameter with Axle Hole 6:08 4745 Propeller 2 Blade Twisted 6:40 92842 Propeller 3 Blade 5 Diameter 7:12 non-Lego boat propeller - Joysway 2-blade P1.4x40mm 83 series 7:51 30332 Propeller 3 Blade 9 Diameter 8:21 4751c Propeller 4 Blade 13 Diameter without Studs 9:02 2952 Propeller 2 Blade 9 Diameter 9:27 64683 Technic, Panel Fairing 3 Small Smooth Long, Side A 10:10 Lego liftarm propeller 2-blade 14x9 45-deg 11:05 18592 Propeller 3 Blade 13 Diameter (Ninjago Airjitzu) 11:39 41325 Propeller 4 Blade, for Flying Model Helicopter 12:26 2740c01 Technic Propeller 3 Blade with Gear 24 Tooth 13:10 non-Lego drone propeller Diatone Bull Nose 4 x 4.5 13:51 89509 - Propeller 1 Blade 14L with Two Pin Holes and Four Axles 14:41 COMPARISON TEST: 2 vs 4 blades 14:58 COMPARISON TEST: short vs long blades 15:23 COMPARISON TEST: 30 vs 45 vs 60 pitch angle 15:49 COMPARISON TEST: narrow vs wide blades Music: Heaven and Hell - Jeremy Blake https://youtu.be/T9IXodtjRgs [9_amdMnDMS4] |
