Determine Direction Cosine Matrix from Multiple Angles of Attack and Sideslip Angles
Determine 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 = dcm(:,:,1) = 0.8926 0.1736 0.4162 -0.1574 0.9848 -0.0734 -0.4226 0 0.9063 dcm(:,:,2) = 0.9811 0.0872 0.1730 -0.0859 0.9962 -0.0151 -0.1736 0 0.9848
alpha — Angles of attack
Angles of attack, specified as an array of m angles of attack, in
dcm defines the transformation of the body frame to the
beta — Sideslip angles
Sideslip angles, specified as an m array of sideslip angles, in radians.
dcm — Direction cosine matrices
Direction cosine matrices, returned as a 3-by-3-by-m matrix,
m is the number of direction cosine matrices.
dcm performs the coordinate transformation of a vector in
body-axes into a vector in wind-axes.
