ZeroAvia发展航空燃料电池系统的压缩机900千瓦ZeroAvia已经开发了一种高性能压缩机燃料细胞航空推进系统,包括公司的第一个ZA600 hydrogen-electric动力系统。(先前的帖子。)氢燃料电池可能提供的能力,实现真正的零排放提供电气化飞行,但一个关键的挑战是提供高流量氧气的化学反应在堆栈提供足够数量的电力。在高海拔地区,空气压缩机需要强大的和有效的,虽然不是向推进系统中添加不必要的重量,从而影响载荷和范围。ZeroAvia压缩机设计和测试特别遵守所有的需求与氢燃料电池航空推进系统。ZeroAvia将把技术作为核心部分的前两个hydrogen-electric引擎:9-19座位飞机目标的ZA600 entry-in-service到2025年,和ZA2000 40与EIS针对2027至80座飞机。ZeroAvia压缩机的初始测试表明,它提供高稳定性能在大范围内的权力和操作环境的要求。支持高达900千瓦的燃料电池系统中,压缩机是强大很多倍比任何现有的燃料电池压缩机和提供了较高的功率密度、ZeroAv ia说。ZeroAvia压缩机也被设计来操作通过一种创新与零延迟流管理方法。压缩机运行在电力核心提供的电力推进系统,消除了额外的逆变器和电动机通常需要在燃料电池系统。 The resulting reduction in complexity will aid certification of ZeroAvia’s powertrains, and fewer components means further reduced weight and greater reliability. This weight efficient system coupled with stable performance across a wide range of parameters makes ZeroAvia’s compressor technology an attractive solution for high-power and high-altitude transport applications. The compressor has been designed to meet all environmental conditions and aerospace standards, and the company plans certification testing to begin over the course of the next year. The performance to date is validation that ZeroAvia’s overarching powertrain will be capable of delivering large commercial, as well as environmental, benefits to airline operators. The company will also leverage the technology to enable enhanced testing of its HTPEM fuel cell stacks for ZA2000 and larger fixed wing and rotorcraft applications. ZeroAvia’s hydrogen-electric engines use hydrogen in fuel cells to generate electricity, which is then used to power electric motors to turn the aircraft’s propellers, with only water vapor emissions. The company has already signed pre-order agreements for nearly 2,000 engines with airlines including American, United and Alaska.
