Abstract
Two arcuate panel sections having a dampening layer between two honeycomb layers form a module which is mounted in multiple elastomeric isolators located within channel members. Support brackets attached to the interior of the aircraft skin support the channels in the overhead area and along the port and starboard deck edge. The module is thereby spaced apart from the aircraft frame. There is a resulting diminution of acoustic transmission from the aircraft frame to its interior passenger area.
Claims16
A module for the interior of an aircraft fuselage containing a fuselage deck, the module comprising:
- (a) contiguous pairs of arcuate port and starboard panels having a first and a second end;
- (b) the first end of each panel mounted in multiple isolaters located within separate overhead support channels;
- (c) multiple support brackets attached to a port and starboard side of the fuselage deck;
- (d) an adjustable port support channel attached to the support brackets on the port side of the fuselage deck;
- (e) an adjustable starboard support channel attached to the support brackets on the starboard side of the fuselage deck;
- (f) multiple isolators mounted in the port and starboard channels for receiving and holding the second end of each arcuate panel;
- and
- (g) the overhead support channels supported by an assembly attached to an overhead portion of the fuselage, the arcuate panels thereby being spaced apart from the fuselage of the aircraft.
A cocoon structure for acoustical protection of passengers within the interior of an aircraft fuselage containing a fuselage deck comprising:
- (a) a multiplicity of panels held together in abutting end to end relationship by one or more joiner arches;
- (b) each panel having a port and starboard component with each component having first and second ends inserted into multiple isolators;
- (c) each isolator engaged within a channel member attached to a mounting element structurally affixed to an interior fuselage surface of the aircraft;
- and
- (d) one or more acoustical panels covering the fuselage deck, the cocoon structure thereby being spaced apart from the fuselage of the aircraft.
A method of mounting an aircraft interior module within an aircraft fuselage containing a fuselage deck comprising:
- (a) mounting support beams from an overhead interior surface of the fuselage;
- (b) attaching a mounting plate containing a port and starboard overhead channel member to the support beams by multiple overhead brackets;
- (c) attaching a port and starboard deck channel member to a multiplicity of port and starboard mounting brackets respectively affixed to the fuselage deck;
- (d) mounting multiple isolator members in each channel member;
- (e) mounting a first end of an arcuate starboard acoustical panel in the isolators in the starboard overhead channel member and a second end in the isolators in the starboard deck channel member;
- (f) mounting a first end of an arcuate port acoustical panel in the isolators in the port overhead channel member and a second end in the isolators in the port deck channel member;
- (g) mounting flat deck acoustical panels over the fuselage deck to form a module spaced apart from the aircraft fuselage.
