Abstract:
Control of ducted-fan helicopter of the flying platform type is carried out in most cases by air vanes with the help of which during calculation of self-damping of the platform there is ensured both a proper margin of stability and also a definite speed of attenuation of perturbed motions. First order of approximations give simple calculating formulas for appraisal of effectiveness of air vanes and self-damping of flying platform on conditions of hovering. Author
