WebJul 30, 2014 · Abstract: Motion-induced oscillations of helicopter sling load seriously degrade their effectiveness and safety. The modeling and dynamics of helicopter sling load are derived. A novel control scheme is designed for reducing the payload swing. Simulations of a large range of motions and various system parameters are used to … WebAug 1, 2013 · Conclusions. A control oriented, physics based helicopter and slung-load model was developed. The helicopter model includes blade flapping and lead-lagging dynamics while for the slung-load a point mass model was used. A quasi-steady aerodynamic drag force acting on the slung load was modeled in the direction of the …
WebThe cables of the sling were modeled as massless rigid extensible rods, which collapse under compressive loads. Extensibility was provided by considering the rods as linear spring with viscous damping. Aerodynamics of the cable were neglected. Tabulated static aerodynamic data were considered for the helicopter as well as the load. WebFederal Aviation Administration
