Thermal Design of the Radar on an Unmanned Airplane

To ensure normal work of the radar installed in an unmanned aero cabin in the bad environment,an air intake is set on the front airframe.This paper analyses the fixing and cooling condition of this radar,the thermal design at the whole/unit level,the thermal analysis at several conditions of typical aero mission and the corresponding flow field simulation.The successful radar flight test has proved the feasibility of this method.This method can be used as a valuable reference for the thermal design of the similar radar or equipment.
