dcmbody2wind - Convert angle of attack and sideslip angle to direction cosine matrix
Syntax
n = dcmbody2wind(a, b)
Description
n = dcmbody2wind(a, b) calculates
the direction cosine matrix, n, for given angle
of attack and sideslip angle, a, b. a is
an m array of angles of attack. b is
an m array of sideslip angles. n returns
a 3-by-3-by-m matrix containing m direction
cosine matrices. n performs the coordinate transformation
of a vector in body-axes into a vector in wind-axes. Angles of attack
and sideslip angles are input in radians.
Examples
Determine the direction cosine matrix from angle of attack and
sideslip angle:
alpha = 0.4363;
beta = 0.1745;
dcm = dcmbody2wind(alpha, beta)
dcm =
0.8926 0.1736 0.4162
-0.1574 0.9848 -0.0734
-0.4226 0 0.9063Determine the direction cosine matrix from multiple angles of
attack and sideslip angles:
alpha = [0.4363 0.1745];
beta = [0.1745 0.0873];
dcm = dcmbody2wind(alpha, beta)
dcm(:,:,1) =
0.8926 0.1736 0.4162
-0.1574 0.9848 -0.0734
-0.4226 0 0.9063
dcm(:,:,2) =
