Identifiers: Hovering. Results of experimental research on helicopter rotors are presented in the hovering regime. Optimum parameters are discussed for heavily loaded rotors. A generalized vorticity theory of the helicopter lifting ro or is se forth; this makes i possible to determine the induced velocity a any point in space for the basic flight mode. The results of aerodynamic research on computation of the flight characteristics of the helicopter rotor in the vertical-descent mode are set forth. Methods are given for determining the characteristics of the rotor. (Author)
