Abstract: A fireproof and thermal insulator product (1) including an Alkaline Earth Silicate (AES) material (2), and at least one of the following: a liquid barrier film (5), an FRP (Fiber Reinforcement Plastic) layer (4), cork (3), wherein the liquid barrier film (5) and the FRP layer (4) are staked onto the AES material (2), and wherein the cork (3) material is also staked onto the AES material (2) or embedded into said AES material (2) in where said cork (3) is configured as a plurality of strips performing a grid structure infilled with the AES material (2).

Abstract: A rotary wing aircraft with a fuselage that comprises an upper primary skin and an aircraft upper deck arranged above the fuselage, wherein the aircraft upper deck comprises a firewall arrangement that defines a fire proof separation at least between at least one aircraft engine and an aircraft interior region, wherein the firewall arrangement comprises at least one funnel-shaped lower firewall that is arranged between the at least one aircraft engine and the upper primary skin of the fuselage, wherein the at least one funnel-shaped lower firewall converges from an outer perimeter to at least one inner collecting point, and wherein the outer perimeter is spaced apart from the upper primary skin of the fuselage.

Abstract: A battery for an aircraft. The present embodiments further relate to an aircraft with at least one such battery. The battery may include a battery casing with a casing wall that forms an interior volume, a plurality of battery cells that is arranged in the interior volume, and a functional layer that is arranged at the casing wall between the plurality of battery cells and the battery casing. The functional layer may include an intumescent material that, in case of a breach of the battery casing, is adapted to ensuring flame containment within the interior volume and mitigation of uncontrolled heat and gas emission from the interior volume through the breach of the battery casing.
