 June 26, 2014, 09:27 Using a field function in changing the pitch angle of helicopter blades #1 New Member     Stephen O'Donnell Join Date: Jun 2014 Location: Ireland Posts: 7 Rep Power: 4 Hi everybody, I am currently simulating a helicopter rotor. As the rotor rotates the blades change in pitch. I'm using a rotational motion for the rotor and morphing motion for simulating the blades pitch rotation. The pitch of a blade is given by this equation: Theta = Theta_o + Theta_1c*Cos(azimuth angle) + Theta_1s*Sin(azimuth angle) where: Theta_o , 1c and 1s are all constants (in degrees), azimuth is the position of the blade in degrees ( 0 degrees is directly downstream) I'm new to field functions so I was wondering if anyone could help me with creating a field function for the rotation if say 1 time step = 1 degree of rotation
