Because of the Corona crisis, there are currently hundreds of aircrafts parked on the ground in the Netherlands alone. To keep them in good condition, the engines and other inlets can be wrapped with mothballing. You can read how this works exactly in this article.

It is important that aircrafts remain in perfect condition

In order to keep aircrafts in perfect condition even when they are on the ground, a number of technical operations are carried out.

This work ensures that when an aircraft is grounded for a long time, an aircraft is still safe and free from defects. This is of course crucial for safety. No things should rust or get stuck. The aircraft must also be able to start immediately if it is to be used again in a while.

How can Cocoon help airlines?

The longer an aircraft has to remain on the ground, the more drastic the measures to be taken to keep the aircraft in the correct condition.

An airplane has engines and other inlets. These are places where insects and fungi can settle if the device is on the ground for a long time.

To prevent this, the plane must be sealed. Mothballing with Cocoon is a suitable means for this. The engines can be sealed in this manner, so that they stay dry and no rusting occurs.

In addition, it is important that the air humidity in the aircraft is maintained, so that electrical components in the cockpit can remain in the correct condition. For this, the aircraft must be closed and dried inside.

Blowing dry air into the engines and into the rest of the aircraft

By blowing in dry air, so-called “temperature spots” with a locally higher relative humidity, caused by blind spots, thermal bridges or lack of air circulation, are prevented.

Lowering the air temperature and humidity ensures a barrier against mold growth and bacteria. In addition, it ensures better hygiene.

The Cocoon mothballing system was invented at the end of World War II to preserve all equipment such as jet fighters and naval ships after World War II ended. With this system they were able to preserve the equipment, and keep it in the highest state of readiness, if necessary.

When machinery are not used for a long time, they must be stored, among other things, to prevent corrosion. Mothballing equipment offers a perfect solution for this.

Within this exceptionally hard mothball skin, the humidity is kept constant at 38%, preventing corrosion and mold. In addition, rubber and other synthetic materials are also protected.

We have used the above method in the past for various Fokker aircrafts and recently for a submarine of the Royal Navy.

Want to know more about Cocoon Mothballing or Coating?

Cocoon is a revolutionary coating product. A high-quality, sprayable plastic that can be used for many purposes.

Cocoon mothballing provides the objects to be preserved with a weatherproof, tough and seamless Cocoon “skin”. Cocoon is able to hermetically seal parts from moisture and dust. Within this Cocoon, the relative humidity is kept around 40%. This prevents the formation of corrosion and fungi. In addition, rubbers and other applied plastics remain intact at this humidity.
