In order to satisfy the requirements of the high reliability of electric control unit (ECU) of the Diesel Engine, the thermal analysis of ECU was performed by using the software FLOTHERM based on the finite volume method. The temperature field of ECU was obtained under different operating conditions. The structural optimization of ECU was completed to solve the problem of local high temperature. As a result, the operational temperature of ECU is reduced under the allowable limit, and its reliability is improved. The physical experiment shows that the thermal analysis and structural optimization are valid. The local high temperature could be reduced effectively and the operational reliability is improved.

The emergence of new types of space and aviation technology necessitates the development of new types of thermal protection systems capable of operating at high temperature and long operating times. There are several types of thermal protection systems for different operating conditions: active thermal protection systems using forced supply of coolant to the protected surface, passive thermal protection systems using materials with low thermal conductivity without additional heat removal, high-temperature systems, which are simultaneously elements of the bearing structure and provide thermal protection, ablation materials. Heat protection systems in the form of rigid tiles and flexible panels, felt and mats are most common kind of heat protecting systems. This article examines the trends of development of flexible reusable heat protection systems intended for passive protection of aircraft structural structures from overheating.
