Dynamic Stability Analysis of a Hovering Helicopter with a Sling Load
Abstract:Equations of motion are derived for a hovering single‐rotor helicopter with zero‐offset flapping hinges, attitude stabilization and a sling load, being an aerodynamically unloaded compound pendulum, suspended from a fixed hook. The motion is restricted to a vertical plane and has in total 3 degrees of freedom. The stability is discussed in general terms. A numerical example for the lateral stability of a large helicopter with a sling load is included. The agreement with experimental results is good.
