Important Components of the Aircraft Engine Cooling System

Typical aircraft achieve flight with the use of an internal combustion engine that ignites air and fuel mixtures, generating propulsion and thrust. This process generates intense amounts of heat within the engine area, and the aircraft engine cooling system ensures that temperature can be kept at a level that protects components and maintains efficient operation of systems. The cooling system may be based on air or liquid cooling, or may be a combination of the two. Each also has their various advantages and disadvantages, and understanding these can make an investment decision easier.

An air cooling system functions through having cylinders and other aircraft engine parts exposed to airflow during flight. Fins or components may be implemented to direct airflow through the intakes to engine components, and temperature distribution is equalized across all cylinders. The air cooling system can sometimes be overly effective during winter months, and thus a winterization kit should be installed to limit airflow. Cowl flaps may be used to direct incoming air flow to the cylinders, and these may be operated by the pilot to mitigate drag effects. Cowls and baffles utilize high and low pressure within the system to create optimal air flow. While air cooling systems can increase drag, they are very light compared to other types.
Liquid cooling is very effective at providing evenly distributed cooling, albeit at the cost of weight. The liquid cooling system allows for rapid engine warm up procedures and can remain at a constant temperature during operation with thermostatic controls. As compared to some other cooling system types, the liquid cooling system can be very reliable, provide for long engine life, and consume less fuel during operation. Many modern aircraft engine parts are cooled using liquid cooling systems, and radiator assembly parts prove very beneficial for heat control.
