SELF-RETAINING CELLULAR HEAT-AND-SOUND ISOLATION Russian patent published in 2013 - IPC B64C1/40 B64G1/22 B64C1/12 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to method if fitting insulation in aircraft device. Aircraft device comprises first and second carcass elements and foam insulation element with first and second ends. Said foam insulation element extends between said first and second carcass elements and squeezed there between by interaction of first and second ends with first and second elements, respectively. It is fixed in place by friction caused by squeezing between first and second carcass elements. One of said first and second ends of foam insulation element features angle in unsqueezed state exceeding zero degrees relative to vertical plane. Method of fitting insulation in aircraft device consists in arranging said element as-squeezed by interaction between first and second ends that feature in unsqueezed state the angle exceeding zero degrees relative to vertical plane with said first and second elements.

EFFECT: decreasing weight of construction and easy fitting insulation.
