The primary performance requirements for the uplock support to meet the minimum
mechanical strength targets in the primary and secondary regions
- Primary -- 50 ksi ultimate tensile strength, 40 ksi
yield strength, and 5% elongation ductility.
- Secondary -- 45 ksi ultimate tensile strength, 36 ksi
yield strength, and 3% elongation ductility.
In addition, the aluminum alloy should be have good
casting properties and be machinable, weldable, and corrosion resistant. |
