Pararotor Dynamics: Center of Mass Displacement from the Blade Plane—Analytical Approach

Abstract: The pararotor is a biology-inspired decelerator device based on the autorotation of a rotary wing whose main purpose is to guide a load descent into a certain atmosphere. This paper focuses on a practical approach to the general dynamic stability of a pararotor whose center of mass is displaced from the blade plane. The analytical study departs from the motion equations of pararotor flight, considering the center of mass displacement from the blade plane, studied over a number of simplifying hypotheses that al… Show more

“…It is worth mentioning that the present paper extends the studies previously developed [17] considering nonlinear effects in the pararotors dynamics and their results on pararotor flight behavior. Those nonlinear terms are the result of using Newton-Euler equations for a rigid body excited with aerodynamic loads coupled with inertial phenomena.…”
