What is the white smoke coming from fighter jets?

Those white streaks planes leave behind are actually artificial clouds. They’re called contrails, which is a shortened version of the phrase “condensation trail.” Airplane engines produce exhaust, just like car engines do. As hot exhaust gases escape from a plane, the water vapor in the fumes hits the air.

What are the clouds on jet wings?

Contrails (/ˈkɒntreɪlz/; short for “condensation trails”) or vapor trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several miles above the Earth’s surface. Contrails are composed primarily of water, in the form of ice crystals.

What causes vapor on jet wings?

When airplanes manuever, wing lift exceeds airplane weight. To allow wing lift to increase, the airflow over the top of the wing speeds up and its pressure drops. When the pressure drops, moisture in the air sometimes condenses and becomes visible. The cloudy white stuff you see is water vapor.

Do planes make clouds?

Planes create their mesmerizing contrails as they soar high in the thin, cold air. Water vapor quickly condenses around soot from the plane’s exhaust and freezes to form cirrus clouds, which can last for minutes or hours.

Why do clouds form on wings?

Clouds form when moist air is cooled to a temperature below it’s dew-point. When an aircraft wing produces lift is the air pressure over the wing reduced. As a result is the air temperature reduced as well, and clouds may form.

Why is there a cloud when breaking sound barrier?

When the object has passed over the observer, the pressure disturbance waves (Mach waves) radiate toward the ground, causing a sonic boom. The lowered pressure condenses the water in the air, creating a vapor cloud.

Why do clouds form over wings?

How are Vapour cone formed?

The vapour cones are created by a shockwave that is generated by the aircraft as it picks up speed. Across these shockwaves there is ‘discontinuity’ in the local air pressure and temperature. This causes the air to lose its capacity to hold water and condensation starts to form, creating the vapour cone.
