Propellers and propfans

Air propellers and propfans ranging from 15 to 30,000 h.p. feature aerodynamic efficiency up to 0.9 The following characteristics have been achieved by virtue of implementing multi-blade conception and using light composite blades:

  • Dimension & weight reducing
  • Noise level reducing
  • Design service life increasing & reliability improving
  • Overhaul ability of composite blades with durability of repaired blade at a level of new one.

The electronic control loop in propellers’ automatic control system allows to implement the following:

  • Expanded set of control functions
  • Diagnostics
  • Propellers’ phase-synchronization with additional noise level reducing
