Aerospace Applications

• - Low weight and volume
• - High reliability

In the past decade there has been movement to more electric architectures in military & commercial aircraft in a trend to reduce weight & maintenance while improving reliability.  Existing aircraft have hydraulic powered systems that actuate retractable landing gear and flight control surfaces among others. Hydraulics are very heavy, powerful, and require significant maintenance. Hydraulic accumulator units (HAU) have been employed on aircraft for over 50 years and now proposals have been made to replace them with an electrical equivalent (EAU).

The addition of the ultra capacitor EAU to the power bus allows for both peak-power fill-in & regenerative power absorption.  This reduces thermal loads by eliminating regenerative power burning and reducing thermal output associated with peak power generation.  Weight reduction is realized by the absence of regen power burning components and lighter power generator designs, which do not require regen protection and peak-power capabilities.
