Safran Electrical & Power provides the best of electrical energy to power the whole of the aircraft systems. The electrical generation consists in converting a part of the engines' or APU's mechanical energy into electrical energy. Our equipment are onboard all types of commercial, regional, business aircraft and helicopters.
The Generator Control Unit (GCU) is part of the aircraft's electrical power generating system and supervises its associated AC generating channel. In addition to controlling the generator, the generator line contactor and protecting against faults in its generating channel, the GCU contains Built-In-Test Equipment (BITE) for fault detection and diagnosis as well as communications circuits which allow fault diagnostics and status data to be passed to the aircraft computers. Depending on customers' requirements, the GCU can be designed to include ground power control and protection to reduce the number of standalone boxes. This type of GCU is called a Generator and Ground Power Control Unit (GGPCU). The GCU/GGPCU control and protection features can be implemented in software or firmware depending on the complexity of the control unit.
From a few kVA up to 250kVA, Safran Electrical & Power has developed a large number of AC generators for civil and military applications.
The generators / starter generators are air or oil cooled and Safran Electrical & Power can provide a number of air inlet and outlet duct options to match the aircraft's ducting requirements.
Safran Electrical & Power's major references of AC generation for civil application are : A380 (JV Aerolec with Thales AES), MA60/600, Global Express (5000&6000). As for military aircraft, our systems are onboard : A400M (JV Aerolec with Thales AES), CN235, C295, C130J, F15 and Helicopters : AW101, CH-47, 292, CH-53K, B525.
