Abstract
In the event of sudden depressurization caused by an explosion in an aircraft cargo compartment, a blast attenuation valve is provided in the aircraft's air channels to form a barrier to the passage of air between the cargo compartment and passenger cabin. The valve contains a mixture of compressible bodies through which air can normally permeate. After an explosion, the bodies block and blast wave by compressing together due to the substantial increase in pressure.
