Simple example of isotropic rotor blade section for CAMRAD use, part b

[rhig2000]

The expected CAMRAD offsets are XC= 0.0725671 ZC= 0.00657381. My formulas compute these for θ = 0.13525064 radians, not degrees. Are the wrong angle units stated in the VABS output file or are the expected XC, ZC values incorrect?

No, if it is in radians, should be 0.00236057. Please double check you calculation. XC, ZC are correct.

I'm calculating θ = 0.00236057 radians = 0.13525064 degrees from Eq. 52. Then, using Eq. 77:
x2 = xT2 - xS2 = -0.07279082336
x3 = xT3 - xS3 = -0.0032710844618
XC = -(x2 * math.cos(θ) + x3 * math.sin(θ)) = 0.072798342
ZC = x3 * math.cos(θ) - x2 * math.sin(θ) = -0.0030992477467

Assuming a common error is using the wrong angle units I tried using θ = 0.13525064 radians = 7.749294186 degrees in Eq. 77. resulting in XC= 0.0725671 ZC= 0.00657381. Where is my error?

Sorry you are right. The correct values are 0.072798342 and -0.00309925
