Tip Shafts
What is the radial acceleration of the blade tip expressed as a multiple of the acceleration of gravity, ?
A model of a helicopter rotor has four blades, each of length 4.00 from the central shaft to the blade tip. The model is rotated in a wind tunnel at a rotational speed of 540 .
The linear speed of the blade tip is 226 m/s
V^2/r = 226^2/4 = 12769
g=9.8
12769/9.8 = 1303
