Failure Type of Micro Gas turbine engine(159)

 

Thermal failure

 

Thermal failure is a type of failure that occurs in micro gas-turbine engines due to excessive heat. There are several types of thermal failure that can occur in micro gas-turbine engines, including:

• Overheating of components: Overheating of components can occur when there is not enough cooling or when the cooling system is not working properly. This can lead to the failure of components such as bearings, seals, and turbine blades.
• Combustion instability: This can occur when the combustion process in the engine is not stable. This can be caused by issues such as a lack of fuel or air, improper fuel-air mixture, or malfunctioning ignition system. Combustion instability can lead to damage to the turbine blades and other internal components.

To prevent thermal failure, regular maintenance of the cooling system and combustion system is essential. It is also important to ensure that the engine is operating within the specified temperature limits and that the temperature sensors are working properly. Additionally, using high-temperature materials for certain components can help to increase the engine's tolerance to heat.
