,air force 90

r = mn * zn / cos (beta) / 2
x = r * cos (t * 360 * B * tan (beta) / (pi * 2 * r))
y = r * sin (t * 360 * B * tan (beta) / (pi * 2 * r))

r = db / 2
theta = t * 45
y = r * sin (theta)-r * (theta * pi/180) * cos (theta)
x = r * cos (theta) + r * (theta * pi/180) * sin (theta)
z = 0
sd0 = mn * zn / cos (beta) +2 * (han * mn)
sd1 = mn * zn / cos (beta)
sd2 = mn * zn / cos (beta) -2 * mn * (han + cn)
alfat = atan (tan (alfa) / cos (beta))
sd3 = cos (alfat) * mn * zn / cos (beta)
db = sd3

z = t * B
