3 MAE 142 Wind-to-Body Axis Transformation Two rotations are needed to transform from the wind axis into the body-fixed axis. Rotate about negative z-axis (3-axis) by the sideslip angle. Rotate about positive y-axis (2-axis) by the angle-of-attack. T W2B = [ cos 0 sin 0 1 0 sin 0 cos ][ cos sin 0 sin cos 0 0 0 1 ] T W2B = [ cos cos cos sin sin sin cos 0 sin cos sin sin cos ]

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
