Hi! I'm currently a grade 12 STEM student and my research title was approved but my methodology was not. I plan to do an evaluation of the performance of different airplane propellers particularly those with 2 blades,3 blades and 4 blades.
I plan to gather data using a prototype balsa wood rubberband plane. Just a small scale. Then it would be tied to a some kind of weight so that it's motion would be circular. I proposed the data gathering using the average speed formula with 2pi(radius)/T.
But my teacher disagreed with it.
Do you know any other equations in which i could test it's efficiency? Or physical equations? Because i proposed that the trial with the farthest distance and lesser time would yield the most efficient one. Please help!!
