Propeller de-icing system

These systems control the pneumatic de-icing of the airframe and indicate possible failures and anomalies of the de-icing process. Verified method of ice elimination on the leading edges of wings Highly reliable control system Possibility to modify technical parameters based on the aircraft type Intuitive control of panel For Safety of Passengers and Crew The system eliminates ice and indicates possible failures The icing can occur with aircraft not only in winter months, but also below the temperature of 3 °C. Even a low icing accretion can affect the wing profile and impair flight characteristics; therefore, the system for airframe de-icing is one of the important systems in terms of flight safety. The system for the pneumatic de-icing control of the airframe is designed for the elimination of the icing occurring during the flight in icing conditions and at the same time for the indication of de-icing system failures. The control system is characterised by high reliability and enables technical parameter modifications depending upon the aircraft type. The panel control is intuitive. System Description Principle of aircraft de-icing Several physical principles are used for aircraft de-icing, the most common methods are the heating of an aircraft part or mechanical elimination of icing on the appropriate part of the airframe. Powerful electrical sources, three-phase converters 115VAC/28V DC, are used for the electrical de-icing of cockpit windshields or for the de-icing of leading edges of propeller blades. The wings and the tail units of the airframe are de-iced pneumatically, normally by section.
