The continuously increasing interest in alternative aircraft propulsion systems is caused by the requirements and demands set by international institutions and government organizations. For instance, nowadays in the European Union, the objective called the European Green Deal seems most demanding. According to this regulation, the members of the European Union should ensure the net zero emission of greenhouse gases by the year 2050. This is why many efforts are devoted to finding ecological solutions for the aviation sector which almost completely relies on fossil fuels at the moment. One of the solutions, which has already proved beneficial for the automotive industry, is the hybrid gas-electric propulsion. Combining the advantages of the electric motors and batteries with the Internal Combustion Engines (ICE) creates an opportunity to reduce fuel consumption, thereby decreasing the greenhouse gas emission. However, challenges such as the immature batteries technology, complicated power management system or the cooling system for high power propulsion systems, among others, need to be dealt with. These all offer great potential for scientific studies, thus the associated literature is accumulating very quickly. The aim of this paper is to update the status and review the state of the art concerning aircraft with hybrid gas-electric propulsion systems. However, the other alternative propulsion systems are also described to indicate and emphasize drawbacks and benefits coming from the hybrid gas-electric propulsion.

混合气电飞机推进系统与替代系统的比较

由于国际机构和政府组织提出的要求和要求,人们对替代飞机推进系统的兴趣不断增加。例如,如今在欧盟,被称为“欧洲绿色协议”的目标似乎要求最高。根据这一规定,欧盟成员国应确保到2050年实现温室气体净零排放。这也是为什么目前几乎完全依赖化石燃料的航空业致力于寻找生态解决方案的原因。已被证明对汽车行业有益的解决方案之一是混合气电推进系统。将电动机和电池的优点与内燃机(ICE)相结合,可以减少燃料消耗,从而减少温室气体排放。然而,电池技术不成熟、电源管理系统复杂或大功率推进系统的冷却系统等挑战尚待解决。这些都为科学研究提供了巨大的潜力,因此相关文献积累得很快。本文的目的是更新现状并回顾有关采用混合气电推进系统的飞机的最新技术。然而,还描述了其他替代推进系统,以指出并强调混合气电推进的缺点和优点。从而减少温室气体排放。然而,电池技术不成熟、电源管理系统复杂或大功率推进系统的冷却系统等挑战尚待解决。这些都为科学研究提供了巨大的潜力,因此相关文献积累得很快。本文的目的是更新现状并回顾有关采用混合气电推进系统的飞机的最新技术。然而,还描述了其他替代推进系统,以指出并强调混合气电推进的缺点和优点。从而减少温室气体排放。然而,电池技术不成熟、电源管理系统复杂或大功率推进系统的冷却系统等挑战尚待解决。这些都为科学研究提供了巨大的潜力,因此相关文献积累得很快。本文的目的是更新现状并回顾有关采用混合气电推进系统的飞机的最新技术。然而,还描述了其他替代推进系统,以指出并强调混合气电推进的缺点和优点。其中,需要处理。这些都为科学研究提供了巨大的潜力,因此相关文献积累得很快。本文的目的是更新现状并回顾有关采用混合气电推进系统的飞机的最新技术。然而,还描述了其他替代推进系统,以指出并强调混合气电推进的缺点和优点。其中,需要处理。这些都为科学研究提供了巨大的潜力,因此相关文献积累得很快。本文的目的是更新现状并回顾有关采用混合气电推进系统的飞机的最新技术。然而,还描述了其他替代推进系统,以指出并强调混合气电推进的缺点和优点。
