美国空军飞行动力实验室结构动力分部发表了一项建议,要求公司投标一项用超塑性成形办法制造铝合金飞机框架的研制计划。该建议提出设计、制造、评价并试验二种以上超塑性成形铝合金机体结构部件。这种部件将采用某种合适的超塑性铝合金来生产并且将代替现有的飞机或导弹部件。
The United States Air Force Flight Dynamics Laboratory Structural Dynamics Division published a proposal to require the company to bid for a plan to manufacture aluminum alloy aircraft frames using superplastic forming. The proposal proposes to design, manufacture, evaluate and test the structural components of two or more superplastic forming aluminum alloy bodies. Such parts will be produced using some suitable superplastic aluminum alloy and will replace existing aircraft or missile components.
