“普惠公司的影响触及到航空业和飞行界的许多人。这本史话如此生动地捕捉住那些先生们、女士们以及各种机器五彩缤纷的历史。这些先生们、女士们和那些机器让我们在技术进步的道路上走过近90年。我们对他们取得的成就致以崇高的敬意。”
——斯蒂文·F.乌德瓦-哈奇
这是一本关于航空界一个著名公司的史话,它与其他同行一样有个令人崇敬的名字,普拉特·惠特尼公司(简称普惠公司)。无论人们飞到哪里,都可以看到普惠公司可信赖的发动机如雄鹰翱翔。然而,普惠公司却是从烟草种植场的简陋仓库起家。1925年,弗里德里克·伦奇勒与一些工程师和制造专家一起在那里创立了普惠公司,发展到今天它已经研制了各种传奇性发动机,诸如,“黄蜂”、“大黄蜂”、“对黄蜂”和“双黄蜂”,以及J57、JT3、JT8、JT9、PW2000、PW4000、F100,乃至今天的F119、F135和齿轮传动涡扇发动机。普惠加拿大公司开辟了全新的小型发动机市场,诸如PT6、JT15、PW100和PW600系列发动机。普惠公司还用诸如RL10之类的航天推进系统进行航天发射,同时开拓燃料电池技术以及航改燃机。
然而,比各种发动机更重要的是,伦奇勒率先描绘出航空将成为全球性行业的发展前景,这一点在1925年很少有人能预见。三个简单原则指导着伦奇勒及其团队:对航空航天发动机的激情、对绝对优秀工程制造的专注和所有工作都必须以良好的业务计划为依据。普惠公司今天依然遵守这些原则制造“可信赖的发动机”,以使客户对发动机的每个方面都满意。
本书也是关于所有普惠人辛勤劳动和献身精神的故事,他们直面各种挑战,诸如“大萧条”,二战极端紧张的生产,在对喷气发动机知之甚少时如何制造喷气发动机?如何让发动机能在高于发动机本身金属熔点的温度下正常运转?以及如何让一个骨子里的美国公司适应新的全球经济,并改造自身成为一个具有全球性制造和支援设施网络的公司?
《可信赖的发动机:普惠公司史话》这本书有助于更好地了解航空业自身的历史以及打造航空业的人们。
