Abstract

Various embodiments of a compressed gas tank assembly are disclosed. According to various embodiments, a compressed gas tank assembly is provided comprising a liner, an inside fastener coupled to the liner, an attachment feature removably coupled to the inside fastener.

First claim

What is claimed is:

1. A compressed gas tank assembly for an aircraft evacuation system comprising:
a liner comprising a cylindrical geometry and having a centerline axis;
a carbon fiber shell enveloping the liner;
a fiberglass shell enveloping the carbon fiber shell;
a port for at least one of charging and dis-charging the gas tank assembly;
an inside fastener coupled to the liner, the inside fastener comprising a first threaded portion;
an outside fastener comprising a second threaded portion; and
an attachment feature comprising a loop configured to rotate about a pivot, the loop removably coupled to the inside fastener via the outside fastener,
a securing element configured to secure the compressed gas tank assembly to a portion of an aircraft, a portion of the securing element passing through the loop,
the inside fastener disposed at least partially within at least one of the carbon fiber shell or the fiberglass shell,
the inside fastener is located at a first end of the compressed gas tank assembly and being concentric with the liner,
the port is located at a second end of the compressed gas tank assembly and being concentric with the liner, and
the first end and the second end are opposite ends of the compressed gas tank assembly.

2. The compressed gas tank assembly of claim 1 , wherein the liner comprises at least of an aluminum or aluminum alloy.

3. The compressed gas tank assembly of claim 1 , wherein the attachment feature is coupled to the securing element, the securing element comprising at least one of a wire, a cable, a nylon webbing, a polyester webbing, a rope, a string, or a tape.

4. The compressed gas tank assembly of claim 1 , wherein the compressed gas tank assembly is configured to hold between 2,000 psig and 5,000 psig of at least one of nitrogen or carbon dioxide.

5. A compressed gas tank assembly for an aircraft evacuation system comprising:
a liner comprising a cylindrical geometry and having a centerline axis;
a carbon fiber shell enveloping the liner;
a fiberglass shell enveloping the carbon fiber shell;
an attachment feature a securing element configured to secure the compressed gas tank assembly to a portion of an aircraft, the attachment feature comprising a loop configured to rotate about a pivot and a portion of the securing element passing through the loop;
an outside fastener coupled directly to the liner via a threaded portion of the outside coupler, wherein the loop is removably coupled to the liner via the outside fastener; and
a port disposed on a second end of the compressed gas tank assembly for at least one of charging and dis-charging the gas tank assembly,
the outside fastener disposed at least partially within at least one of the carbon fiber shell or the fiberglass shell,
wherein the port is concentric with the liner,
the attachment feature is concentric with the liner, and
the first end and the second end are opposite ends of the compressed gas tank assembly.

6. The compressed gas tank assembly of claim 5 , wherein the liner comprises at least of an aluminum or aluminum alloy.

7. The compressed gas tank assembly of claim 6 , wherein the attachment feature and the liner are integrally coupled.

8. The compressed gas tank assembly of claim 6 , wherein the attachment feature is coupled to the securing element, wherein the securing element comprises at least one of a wire, a cable, a nylon webbing, a polyester webbing, a rope, a string, or a tape.

9. The compressed gas tank assembly of claim 8 , wherein the compressed gas tank assembly is configured to hold between 2,000 and 5,000 psig of at least one of nitrogen or carbon dioxide.
