摘要：

The twisting of a load on the outer suspension of a helicopter is regarded as a way to provide its transportation stability during the flight. Basic physics of the load stabilization is discussed. The experimental research results have been presented to determine amplitude-frequency characteristics and aerodynamic coefficients of rotating loads. The loads have the form of a parallelepiped and a ring cylinder. Three factors affect the stabilization of a rotating load. They are: the gyroscopic effect, symmetrization of the load shape and mismatch in oscillation frequencies.
