1988年,美国政府制定了综合高性能涡轮发动机技术(IHPTET)计划,它的目标是到2000年使发动机的推进能力提高1倍,即与1990年的基准发动机比,到1997年推重比提高90％,到2003年提高100％;燃烧室进口温度提高204℃(400°F)。到了20世纪90年代中期,又提出了到2003年使生产和维护费用降低35％的目标。这反映出美国国防部更关心发动机的可承担性,21世纪初调整了IHPTET计划下一步的目标,制定了通用的、可承担起的先进涡轮发动机(VAATE)计划。该计划的主要工作是研制一台通用核心机,再从该核心机研制出更高性能、更高耐久性和更低费用的民用和军用发动机,从而达到从2000年到2015年使可承担性降低到原来的1/10的目标。 VAATE计划共分2个阶段,第1阶段是从2004年到2010年,目标是以2003年研制的VAATE验证核心机为基础,使发动机的可承担性降低到1/6;第2阶段是从2009年到2015年,目标是使发动机的可承担性降低到1/10。工作的基准是目前先进的动力装置,如F119发动机。
In 1988, the U.S. government established the IHPTET project, which aims to double the propulsion capacity of the engine by the year 2000, that is, by 90% of the baseline engine ratio in 1990 and by 90% by 1997 %, Up to 100% by 2003; the inlet temperature to the combustion chamber increased by 204 ° C (400 ° F). By the mid-1990s, the target of reducing production and maintenance costs by 35% by 2003 was also raised. This shows that the U.S. Department of Defense is more concerned about the affordability of engines. In the early 21st century, the IHPTET plan was adjusted to the next goal and a common and affordable VAATE plan was put in place. The main task of this program is to develop a common core machine, then develop a higher performance, higher durability and lower cost of civilian and military engines from the core machine, so as to achieve affordability from 2000 to 2015 Reduce to the original 1/10 goal. VAATE program is divided into two phases, the first phase from 2004 to 2010, the goal is based on the VAATE core machine developed in 2003 based on the engine to reduce the affordability of 1/6; the second stage is from From 2009 to 2015, the goal is to reduce the engine’s affordability to 1/10. The benchmark for work is the current state of the art powerplant, such as the F119 engine.
