From our research and development efforts, our scientists have created a compact gallium arsenide-based switch capable of handling ultrahigh voltages (over 75,000 V) and current densities in less than a billionth of a second, with ultralow jitter.
Applications that require rapid application of high voltages will benefit from this technology breakthrough. The initial application for IBIS™ PCSS enables a portable capability for future nuclear weapon effects evaluations to ensure sufficiently hardened equipment.
Our challenge was to improve the structural efficiency of launch systems by replacing the Ti-5Al-2.5Sn ELI alloy for Liquid H2 Turbopump Impellers with an aluminum-based alloy. Aluminum is about 1.6 times lighter and is less sensitive to the hydrogen environment. Al-7042 exhibited good properties over a broad temperature range (-269˚ C to 100˚ C). A Liquid H2 Turbopump Impeller was fabricated and successfully spin tested.
The Super High Strength AI Alloy 7042 offers:
