The invention provides a multi-electricity comprehensive energy system for a wing-body fusion aircraft, and belongs to the field of aircraft propulsion and energy. The problem of multi-working-condition design is solved, a multi-electricity comprehensive energy system not only comprises a traditional center line energy power system (a second aviation kerosene storage tank, a second electric pump, a fifth flow divider, a sixth flow divider, a turbine and a second combustion chamber), but also comprises other energy power systems and energy power systems with symmetrical side wings, and therefore when taking off, the energy power systems are connected with the power system. A large amount of fuel can be injected into a gas turbine channel, and the temperature in front of an inlet of a spray pipe can be increased and can reach 2200 K. In the cruise working condition, the ducted fan can be driven through the fuel cell, propelling work is mainly output, and low oil consumption rate is achieved. According to the system, various high-power-density technical means are adopted, the reformer and the membrane separation reformer are integrated, and compared with a traditional fuel cell, the power density of the fuel cell in the system can be improved by 80% or above.
本发明提出了一种用于翼身融合飞行器的多电综合能源系统,属于飞行器推进和能源领域。本发明解决了多工况设计难题,多电综合能源系统中不仅仅有传统的中线能源动力系统(二号航空煤油储箱、二号电动泵、五号分流器、六号分流器、涡轮和二号燃烧室),还有其他能源动力系统和侧翼对称的能源动力系统,因此在起飞时,可通过在燃气涡轮通道内注入大量燃料,努力提高喷管入口前温度,可达到2200K。本发明在巡航工况时,可通过燃料电池驱动涵道风扇,主要输出推进功,实现低耗油率。本发明采取了多种高功率密度的技术手段,集成了重整器和膜分离重整器相比于传统燃料电池,该系统中的燃料电池功率密度可提高80%以上。
