The invention provides an infrared stealth unmanned aerial vehicle and a control method for the wake flow temperature of the unmanned aerial vehicle. The unmanned aerial vehicle comprises a vehicle body, a cooling medium heat exchange grating, a cooling medium storage device, a fuel cell and a master control system. The cooling medium heat exchange grating, the cooling medium storage device, the fuel cell and the master control system are all arranged in the fuselage; the cooling medium storage device is communicated with the cooling medium heat exchange grating; the cooling medium heat exchange grid is arranged at a gas outlet of the fuel cell; the master control system is connected with the fuel cell; the general control system is used for controlling the supply quantity of a cooling medium in the cooling medium storage device and regulating the temperature of tail gas at the gas outlet of the fuel cell by adopting the cooling medium heat exchange grating; the cooling medium is mixed with the tail gas at the gas outlet of the unmanned aerial vehicle fuel cell and then discharged, the temperature difference between the wake flow temperature of the unmanned aerial vehicle and the environment temperature can be reduced, and the unmanned aerial vehicle can be prevented from being detected by infrared rays.

    本发明提出了一种红外隐身的无人机及无人机尾流温度的控制方法,所述无人机包括机身、冷却介质热交换格栅、冷却介质存储装置、燃料电池及总控系统;所述冷却介质热交换格栅、所述冷却介质存储装置、所述燃料电池及所述总控系统均设置在所述机身的内部;所述冷却介质存储装置与所述冷却介质热交换格栅相连通;所述冷却介质热交换格栅设置在所述燃料电池的出气处;所述总控系统连接所述燃料电池;所述总控系统通过控制所述冷却介质存储装置中冷却介质的供给量,采用所述冷却介质热交换格栅调节所述燃料电池的出气处尾气的温度;本发明使用冷却介质与无人机燃料电池出气处尾气混合后排出,能够降低无人机尾流温度和环境温度的温度差,从而可避免无人机被红外探测到。
