Open rotor propellers ice protection system


ICEPS-ORPS project aims to develop a new IPS (Ice protection system) for composite propeller blades, which can be integrated with composites. From the current state of the of ice protection system (IPS) technologies, seven new active IPS technologies have been selected as having potential for being developed into a cost effective propeller IPS of high technical performance.

These are:

  • hot air heating
  • laser heating
  • heating foils either surface mounted or embedded with either steady state or pulsed electrical heating
  • electromagnetic repulsion/attraction
  •  microwave heating
  • low frequency forced vibration
  • guided wave ultrasonics

Synergistic combination of these IPS approaches and synergistic combination of any one with a number of passive technologies such as non-intrusive ice-phobic chemical coatings will also be investigated.


An effective ice protection system is essential for the safe operation of the advanced open rotor engine. With other innovative technologies used to develop this engine, the IPS technologies developed in this proposal make a contribution towards the overall impact of the advanced open rotor project in terms of economic, maintenance, environmental and societal benefits.
