The situation where aircraft become invisible by entering a pure white cloud for a few seconds: Vapor Cone

At this point, the first questions that come to mind are: “Can something like this really happen?” Or “Is this an optical illusion?” It’s possible.

Bride, details of this phenomenon let’s see.

A vapor cone, also called a shock collar or Mach diamond, is the visible cloud of dense water vapor that forms around an aircraft as it approaches transonic speeds.

A vapor cone typically occurs in the immediate aftermath of an object moving through the atmosphere at high speed, such as an airplane, a rocket/missile launch, or an explosion-induced shock wave. rapid compression and expansion of air is caused by.

This expansion and compression causes a sudden drop in air pressure and temperature, causing the loss of water vapor into the atmosphere. condenses into small droplets and creates a distinctive cloud or cone-shaped structure around the object.

Various factors play a role in the formation of the vapor cone.

This; atmospheric conditions such as the speed, humidity and temperature of the object and the presence of nucleation sites for water vapor condensation. Furthermore, the length of time a vapor cone is visible to the human eye can vary greatly, again depending on several factors.

At this point the speed and duration of the event, atmospheric conditions, distance and viewing angle are effective. For example, the time that the vapor cone remains visible depends on the speed of the aircraft duration of the event causing the phenomenon is associated. Typically, vapor cones form and disappear within seconds.

Again humidity levels and temperature, affects the durability of the vapor cone. Vapor cones can last longer when there is more moisture in the air compared to dry conditions.

In addition, the distance of observers from the event and the viewing angles how long the vapor cone remains visible can influence. If it is observed from a considerable distance or from an angle where it quickly disappears from view, the time to visibility may be reduced.
