Abstract
This paper presents a reduced order model for describing the steady-state and dynamic behavior of a single-winged samara seed pod undergoing autorotative descent. Blade Element Theory is employed to capture the span-wise behavior of a samara. By neglecting lateral motion of the center of mass and prescribing a roll angle, a simplified and compact model is developed while retaining reasonable accuracy in comparison to experimental data published in the literature. Steady-state results confirm the validity of assuming a small roll angle, which helps reduce model complexity. Simulation of the dynamics yields reasonable transient behavior and convergence to equivalent steady-state values. Accuracy of the reduced order model suggests the plausibility of designing and controlling simple autorotative mechanisms.
