The Newcastle university involvement in the H2Gear project focuses on the development of the electrical network for the H2Gear all electric aircraft. This project will be specifically centred on the development of a protection system for the aircraft electrical network, creating optimal fault protection, reconfiguration and discrimination strategies designed to best protect the electrical network from faults. Aircraft fault protection systems and certification have not yet had to cater for fault protection for an all-electric aircraft as past commercial aircraft have also relied on hydraulic and mechanical systems to various extents. Therefore it is first important to establish the requirements for the fault protection system given the inter-reliant nature of on-board networks and the potential for cascading faults in a fully electric system. It should be within the capacity of the protection system to detect when a fault is occurring, determine the nature of the fault and its location, discriminate and execute the correct response to isolate and eliminate faults. Through simulations the effectiveness of these strategies in protecting the network from faults and ultimately ensuring the safe operation of the aircraft will be investigated, as will the practicalities of physically implementing these designs and integrating into the rest of the systems.

参与H2Gear项目的纽卡斯尔大学专注于为H2Gear全电动飞机开发电气网络。该项目将专门围绕飞机电网保护系统的开发，创建最佳故障保护，重新配置和识别策略，旨在最好地保护电网免受故障的影响。飞机故障保护系统和认证尚未满足全电动飞机的故障保护，因为过去的商用飞机也在不同程度上依赖于液压和机械系统。因此，考虑到车载网络的相互依赖性和全电力系统中级联故障的可能性，首先必须确定故障保护系统的要求。它应该在保护系统的能力范围内，以检测何时发生故障，确定故障的性质及其位置，区分并执行正确的响应，以隔离和消除故障。通过模拟，将研究这些策略在保护网络免受故障影响并最终确保飞机安全运行方面的有效性，以及物理实施这些设计并集成到其余系统中的实用性。
