Electric Systems

Hamilton Sundstrand Electric Systems, headquartered in Rockford, Ill., is the industry leader in electric power systems for commercial, regional, business, and military aircraft. Products include main and emergency power generation, power conversion and motor control, power distribution, and aircraft utilities management. Our products are complemented by our system design expertise which enables us to offer innovative physical and functional integration concepts that extend beyond the traditional boundaries of aircraft electric systems. 

Electric power generation requirements vary with the needs of the aircraft. Hamilton Sundstrand Electric Systems is uniquely able to offer optimum solutions with a complete range of electric power generation options including constant and variable frequency ac and high voltage dc systems.  For more electric aircraft applications, we also offer main engine and auxiliary power electric starting. There are currently two production aircraft programs featuring main engine electric start and Hamilton Sundstrand Electric Systems is the electric system supplier for both.

HS Elektronik Systeme GmbH is located in Nordlingen, Germany designs and manufactures Intelligent Power Modules. These power modules, Solid State Power Controllers (SSPC) and Solid State Relays (SSR), power distribution modules and power supplies are predominantly used in power generation and primary and secondary power distribution systems in aircraft, but also in motor drives and jet engine controls. The company builds its own product-specific test equipment and has its very own model shop. Burn-in, thermal cycling, temperature and EMI pre-compliance testing as well as constant acceleration testing are performed in-house. A team of highly qualified engineers and technicians is responsible for the design, development and production. The dedicated staff and highly trained employees provide the flexibility to quickly respond to customers' needs.

Electromagnetics creates solutions to satisfy reliable and efficient rotating electrical components and power generation for aerospace applications, hybrid electric vehicles and transportation refrigeration.  We design, manufacture and integrate advanced products and technologies for the Boeing 777-767-757 and 747, Sykorski Helicopters, the Airbus A380, Embraer, Canadair, Dash 8, Dehavaland, and advanced fighter jets.  Our industry-leading scientists and engineers allow us to offer custom hybrid motors and generators that are some of the most advanced in the world, designed to make your vehicle run efficiently and reliably. Electromagnetics engineers and manufactures state-of-the-art generators for the Carrier Corporation Vector transportation refrigeration units. Vector systems use patented all-electric hybrid technology to deliver maximum performance, efficiency and reliability.

The Page Aerospace business has recently moved from Electric Systems to the Interiors division of UTC Aerospace Systems. For more information on Page Aerospace, please visit http://www.pageaerospace.co.uk/.

In normal aircraft operation, the propulsion engines drive the generators that produce electric power.  In extremely rare cases, catastrophic events on-aircraft have resulted in total loss of engine power or generator output.  Hamilton Sundstrand’s emergency power systems have enabled critical aircraft systems to continue operating until the aircraft was safely landed.  To date, more than 1,600 lives have been saved in 15 different occurrences.
