In recent years researchers has taken keen interest in air-conditioning failure occuring at the pneumatic channel of the aircraft which is subjected to hot air pressure cycle, causing the stress developed in the material to be cyclic in nature. Due to the occurence of ice build-up in some parts of the ﬂow channel, to prevent it, pneumatic channel is provided feed with hot air that is bleed from the engine of the aircraft. Mainly titanium is used for pneumatic system components of aircraft due to its favorable characteristics. The crucial part where the failure occurs is taken in to consideration and a new model of the part has been created. CATIA V5 software is used for modeling and thermal analysis is done with the ANSYS software. From the obtained result it is evaluated that the rectangular duct has high heat ﬂux than square and circular ducts.
