Balancing small engines-flywheels

When you create a small spacecraft there is the problem of redressing the imbalance of the rotor-flywheel of the small engine flywheel with the selection of weights, while the mechanical contact method leads to elastic deformation in the supports of rotation, which has a negative impact on their work especially at high speeds of rotation of the flywheel. From this perspective, there is a need to study other ways of balancing of rotors, flywheels, namely contactless bal- ancing of rotor of flywheels with the help of concentrated energy fluxes of laser and electron-beam evaporation of the metal. The technology of balancing with an electron beam has a number of advantages over the laser technology of bal- ancing for the realization of balancing of rotors of flywheels. For example, it is possible to implement the process of redressing of imbalance in the vacuum that brings the balancing conditions to real operating conditions. Also the reflectance of energy in the processing of electron beam is much lower than during laser processing, which demon- strates the efficiency of the process. The dependences of the intensity of evaporation from the settings of the laser and electron beam are defined. Contactless balancing of rotors of flywheels with the help of concentrated energy fluxes evaporation of metal is cur- rently possible, but it is necessary to have special equipment with the required capacity of operation.
