New General Approach to Airplane Rotation Analysis

The paper presents a new approach to analysis of dynamic properties of the rotating airplane. The analysis is based on the rate of rotational energy and a full non-linear model of airplane dynamics. It can be applied to a whole range of attack angles. To provide stable rotation, it is sufficient to use algebra and know only the inertial properties of the airplane and the functional relations of either aerodynamic moments or angular accelerations. We prove that the results are fully congruent with those obtained by conventional methods within the scope of validity of the simplified model.
