Six degrees of freedom (6DoF) refers to the freedom of movement of a rigid body in three-dimensional space. [citation needed] In aeronautical and aerospace engineering intrinsic rotations around these axes are often called Euler angles, but. 31), the resulting expressions, together with l 2 + m 2 + n 2 = 1, provide enough information to solve for the direction cosines, thus specifying the orientation of s 1 relative to the xyz system. Email this Article Aircraft principal axes. Each of the axes shows the tilt angle with respect to the field of gravity. Principal Axes of Inertia For a general three-dimensional body, it is always possible to find 3 mutually orthogonal axis (an x,y,z coordinate system) for which the products of inertia are zero, and the inertia matrix takes a diagonal form.
