Resilient protection systems for more-electric and hybrid electric aircraft applications

更多的电力和混合动力航空航天系统提供了提高效率和减少排放的潜力，是向低碳飞行过渡的关键部分。然而，这两个系统的特点是越来越多地使用大型和飞行关键电力负载，这需要提供高度可靠的电力供应，以确保飞行安全运行。因此，使用可重新配置和有弹性的电力系统架构对于满足这些苛刻的负载可用性目标至关重要。拟议的PHD将研究新的弹性和可重新配置的飞机电力系统架构，采用固态、限流、保护和重新配置设备等关键使能技术，并采用新的接地和保护解决方案，以实现低维护、低重量的电力系统解决方案。

More-electric and hybrid electric aerospace systems offer the potential to deliver improved efficiency and reduced emissions and are a key part of the transition to low carbon flight. However, both systems feature an increasing utilisation of large and flight-critical electrical loads which require the provision of a highly reliable supply of electrical power to ensure safe flight operation. The use of reconfigurable and resilient electrical power system architectures is hence essential to meeting these demanding load availability targets. The proposed PhD will investigate new resilient and reconfigurable aircraft power system architectures, embracing key enabling technologies such as solid-state, current limiting, protection and reconfiguration devices, and employing new grounding and protection solutions in order to achieve, low-maintenance, low-weight power system solutions.
