Aircraft Insulation blanket
When aircraft at high altitude, the outside temperature is about -60-degree Fahrenheit.
In combination with pressurization, aircraft insulation material helps keep the cabin warm by filling the space between the interior wall and the aircraft fuselage.
As we know that fire retardant material is must for all aircraft.
Purpose of Aircraft Insulation blanket
The reason of choosing fire retardant material is to minimize the potential for a fire and help to prevent or slow flame spreads if a fire occur, which will provide maximum evacuation time and helps to ensure the safety of passengers and crew members. Although, It’s a requirement of regulator for manufacture that the interior material for aircraft should have self-extinguishing quality.
primary purpose of aircraft insulation blankets
1.Protect passengers from frigid condition at high altitude
2.Minimize loss of heat from the fuselage
3.Stop the formation of condensation and
4.Reduce noise level in cabin.
5.Protect electronics component from condensed water.
6.It act as insulation material between fuselage structure and electrical component.
Location of Aircraft Insulation blanket
Insulation blanket normally installed on fuselage structure in pressurized area.
The Density of insulation blanket is vary depending on their location in an aircraft.
This is determined by design requirement in order to comply with thermal and acoustic requirements of particular area.
Different thickness of insulation identified according colour of insulation blanket.
The areas where the affected insulation blankets are installed include, but are not limited to, the following areas:
(i) Crown area of the airplane;
(ii) Areas behind flight deck panels and circuit breaker panels;
(iii) Areas behind sidewalls, lavatories, closets, and galleys;
(iv) Cargo compartment areas;
(v) Air ducting;
(vi) Waste and water tubing; and
(vii) Areas attached to the underside of floor panels
