The 6 Paradoxes of our Aviation Blanket

Cocoon’s Improved Thermal Acoustic Blanket (ITAB) for the CH-47 manages to combine properties that on the surface seem incompatible. It took years of R&D, but thanks to a lot of trial and error, and some highly technical new textiles, we were able to make possible what at first seemed impossible.

Lightweight but durable
Cocoon’s CH-47 aviation blanket is 140+ lbs. lighter than the old blanket, while at the same time exceeding durability standards, which is essential in a workhorse like the Chinook.

Lightweight but acoustically absorbent
Despite being significantly lighter, Cocoon’s ITAB features a 40% improvement in acoustic absorbency in the cargo bay.

Waterproof but air-permeable
Our blanket is completely waterproof but also highly air-permeable. It keeps water from getting in, while letting vapor out, preventing the “greenhouse effect.” That means moisture won’t get trapped against the airframe and cause corrosion.

Filter to 0.3 microns but remain air-permeable
Cocoon’s blanket won’t let particulates through to the airframe (not even fine sand such as “moon dust”), yet it retains its air-permeability thanks to a membrane with over a billion pores per square inch. 

Oleophobic but air-permeable
Cocoon’s aviation blanket repels fluids, oils, and lubricants, so it won’t get contaminated or heavy, but remains highly air-permeable.

Attach securely without trapping moisture
We completely redesigned the attachment system so that the blanket stays firmly in place. There’s no longer any need for 550 cord. However, because of its air-permeability, it can sit firmly against the airframe without trapping any moisture. 

Advanced technologies aren’t just found in cars and computers, they now also come in the form of a textile.
