Abstract：The internal environment induced by airplane platform is an actual work environment of the air-borne equipment,and the induced environment temperature is a main influence factor on airborne equip-ment work.Aimed at the problems of modeling and simulation of internal environment temperature in-duced by airplane platform,the main influence factors are analyzed,and the modeling method of induced temperature is proposed based on similar heat transfer structures classification.The aircraft's similar heat transfer structures are classified as a wing cabin structure,a ring cabin structure,a big cabin structure,an open cabin structure,and a thermal protection structure.The general lumped parameter models of the 5 heat transfer structures are established.Taking Modelica language as a tool,the simulation models of the 5 heat transfer structures are also established.The similar temperature regional division is made taking a cer-tain type aircraft as example,and the 5 heat transfer structure simulation models are used.The internal environmental temperature simulation model of whole airplane platform is established.The simulation re-sult verifies the feasibility of the modeling and simulation method.The simulation results show that the air temperature in the fuselage cabin can be up to 70℃,the temperature in the engine nacelle can be up to 140℃ in short time,and between 90℃~110℃ in long time,the temperature in the engine thermal protec-tion structure can be up to 160℃.
