Title:
SYSTEM FOR SUPPLYING ELECTRICAL POWER TO DE-ICING ELEMENTS IN AN AIRCRAFT PROPELLER
Document Type and Number:
WIPO Patent Application WO/1997/024261
Kind Code:
A1
Abstract:
The proposed electrical power supply system pertains to aircraft electrical equipment and can be used in aircraft de-icing systems with electrical propeller heating. The proposed system comprises measuring converters which convert the rotational frequency of the propeller and electrical generator stator, and control and malfunction monitoring systems. The stator is divided into two parts. The first part comprises inductor pole permanent magnets, rotates freely and can be fixed by a braking coupling. The second part is fixed and provided with a coil for monitoring malfunctions in the resistive heating elements and electrical generator coils. The proposed system eliminates the need for a heavy-duty power supply and reduces the weight of the system.
