为了应对20世纪70年代的石油危机，NASA创建了先进涡轮螺旋桨项目（ATP），以成熟高速螺旋桨技术，从而相对于那个时代的涡轮风扇发动机大幅减少燃油消耗。单旋转和对旋转概念都是在地面设施和飞行中设计和试验的。作为这项工作的一部分，提出了一些新的概念/配置。高速螺旋桨概念确实节省了燃料，尽管有一些声学和结构上的挑战需要克服。当燃料价格下降时，激进的新发动机配置的商业案例崩溃，研究重点回到高旁通管道配置。包括推进机体一体化、对飞机重量声学敏感性和认证问题。
In response to the 1970s oil crisis, NASA created the Advanced Turboprop Project (ATP) to mature technologies for high-speed propellers to enable large reductions in fuel burn relative to turbofan engines of that era. Both single rotation and contra- rotation concepts were designed and tested in ground based facilities as well as flight. Some novel concepts/configurations were proposed as part of the effort. The high-speed propeller concepts did provide fuel burn savings, albeit with some acoustics and structural challenges to overcome. When fuel prices fell, the business case for radical new engine configurations collapsed and the research emphasis returned to high bypass ducted configurations. include propulsion airframe integration, acoustic sensitivity to aircraft weight and certification issues.
