Artificial Moment Unbalance as a Restrictor of the Rotor Angular Speed

Evacuation of people from burning high-rise buildings is a complex task. For this purpose, a rescue device has been designed that does not require special training or preparation. It can be used for self-descent of people and goods and for rescue of the injured who are in an unconscious state. It makes it possible to exclude centrifugal braking mechanisms used in conventional descending devices from the design of the proposed device. It allows the use of the natural frictional torque in the drum bearings and the minimal possible weight not exceeding 10 kg at the descent height of up to 100 m. This design can be used to develop portable reusable rescue devices of various applications. The developed and experimentally tested rescue descending device operates in the stable dynamic equilibrium where the load can descend at a constant speed.
