去年12月初,波音直升机分部完成了首架具有生产型特征的V-22机身的组装工作,并把其运至阿林顿完成与贝尔组装的V-22机翼的对接工作。在V-22计划中因综合产品组(IPT)采用了大量先进制造技术和新工艺方法,使工程与制造发展阶段(EMD)最初3年中生产的V-22的离厂成本降低了23％。迄今,已使该计划全寿命期总计划采购费节省了50亿美
In early December last year, the Boeing Helicopter Division completed the assembly of the first production-type V-22 fuselage and shipped it to Arlington for docking with the Bell-mounted V-22 wing. The introduction of a large number of advanced manufacturing and new process technologies for the Integrated Product Group (IPT) in the V-22 program resulted in a 23% reduction in the cost of leaving the factory for the V-22 produced during the first three years of the Engineering and Manufacturing Development Phase (EMD) . So far, a total of 5 billion U.S. dollars has been saved in the total planned lifetime procurement life of the program
