Abstract:

As mission scenarios expand and flight profiles change, both military and commercial aerospace vehicles will be required to operate in a broader range of environments than current flight vehicles. This implies the need for increased reliability across a wide range of environmental conditions, i.e., environmental parameter space. A critical element to the overall operational capability of the vehicle is the reliability of the electrical systems onboard. In the case of electrical systems insulation, both reliability and lifetime can depend on addressing the relevant environmental issues in the design phase, to minimize or eliminate the degrading effects of corona or gas volume breakdown that can lead to insulation system failures. The information contained herein is a technology review of corona and discharge research, including technologies specific to the characterization of gaseous insulation breakdown in geometries of high electrical field stress. The report attempts to better define the parameter space for gas environments applicable to aerospace power in advanced military flight platforms, with some applicability to commercial aircraft and spacecraft, as well.
