Shock cooling
Shock cooling refers to the theory that damage to engines (particularly air-cooled aviation piston engines) may occur because of an excessively rapid decrease in temperature.
The situation where rapid cooling arises is on
Manifestation
Damage from shock cooling is most commonly believed to manifest itself as stuck
Analysis
While the subject is very controversial, some believe shock cooling, as commonly explained, is nothing but a
Detection and prevention
A single cylinder head temperature (CHT) sensor, or in more sophisticated installations, an array of sensors, one for each cylinder, may be employed to monitor the temperature and cooling rate of the engine. Spoilers on the wings may also be deployed to lose lift without having to reduce engine power substantially, slowing the rate of engine cooling.[3]
