The invention relates to the technical field of aircrafts, in particular to an aircraft fuel oil thermal management system, a control method and an aircraft. The aircraft fuel oil heat management system comprises a fuel oil heat exchange flow path, a lubricating oil heat exchange flow path and a power generation flow path. Through the arrangement of the power generation flow path, the heat load of the lubricating oil can be recycled when the heat load of the lubricating oil is too large, a part of the heat load (namely part of heat) of the lubricating oil passes through the evaporator to heat a working medium in the power generation flow path, the heated working medium enters the expansion machine to participate in acting, and then the power generator connected with the expansion machine is pushed to work. The purpose of converting heat energy of the lubricating oil into electric energy is achieved. In addition, fuel oil flowing out of the aircraft fuel oil pump exchanges heat with a working medium in the power generation flow path through the condenser, so that it is guaranteed that the temperature of the fuel oil entering the combustion chamber does not exceed a limiting value.
本发明涉及飞行器技术领域,尤其涉及一种飞行器燃油热管理系统、控制方法及飞行器。飞行器燃油热管理系统包括燃油换热流路、滑油换热流路和发电流路。发电流路的设置,能够在滑油热载荷过大时对滑油热载荷实现再利用,通过滑油一部分热载荷(也即一部分热量)经过蒸发器对发电流路中的工质进行加热,被加热的工质进入到膨胀机内参与做功,进而推动与膨胀机连接的发电机工作,实现将滑油的热能转变成电能的目的。另外,从飞机燃油泵流出的燃油通过冷凝器与发电流路中的工质进行换热,以保证进入燃烧室的燃油温度不超过限制值。
