WHY is there a WHITE CLOUD? Explained by CAPTAIN JOE
Captain Joe・6 minutes read
White clouds forming in the engine during takeoff are due to air cooling, leading to water vapor condensation explained through a plastic water bottle experiment. Warmer air's capacity to hold water vapor and relative humidity are key factors in cloud formation, impacting engine performance minimally as the cloud vanishes with high compressor temperatures.
Insights
- Cloud formation in the engine during takeoff is due to air cooling below the dew point, causing water vapor to condensate, illustrating the impact of relative humidity on this phenomenon.
- Although the cloud formation may slightly impact engine performance, the high temperatures in the compressor quickly dissipate the cloud, showcasing the resilience of the engine system in managing such occurrences.

Engine Cloud Formation Explained Through Experiment
- White stuff in engine during takeoff roll is explained as a cloud forming due to air cooling below dew point, causing water vapor to condensate.
- Warmer air can hold more water vapor, with relative humidity playing a key role in cloud formation.
- The process is demonstrated using a plastic water bottle experiment, simulating the engine intake pressure drop and air acceleration.
- Despite affecting engine performance marginally, the cloud dissipates as air passes through the compressor at high temperatures.
