美国典型航空发动机发展计划及对技术创新的影响

摘要

In this paper, the Integrated High Performance Turbine Engine Technology (IHPTET) program and the Versatile Affordable Advanced Turbine Engines (VAATE) program were introduced as the typical aeroengine development program in American aeroengine development process. Then, the inlfuence of IHPTET program and VAATE program on American aeroengine technology was studied based on patents data collected from USPTO, included patent distribution in the year, technology distribution as well as the major research institutions.%介绍了在美国航空发动机发展历程中具有重大意义的典型发展计划，综合高性能涡轮发动机技术（IHPTET）研究计划和通用的经济可承受的先进涡轮发动机（VAATE）研究计划，并以UPSTO专利数据为基础，从发展趋势、技术分布以及机构分布等维度研究了这两个计划对美国航空发动机技术创新的影响作用。
