Abstract

A multi-staged suspension line length parachute may include a suspension line having a primary length and a secondary length. The primary length may be deployable upon a first deployment of the multi-staged suspension line length parachute. The secondary length may be prevented from deployment until the primary length has fully deployed. An attenuator may attach a first portion of the secondary length to a second portion of the secondary length.

First claim

What is claimed is:

1. A multi-staged suspension line length parachute, comprising:
a suspension line comprising a primary length and a secondary length, wherein the secondary length is folded to form an apex, and wherein a first portion of the secondary length extends from a first end of the secondary length to the apex of the secondary length, and wherein a second portion of the secondary length is located adjacent the first portion and extends from the apex of the secondary length to a second end of the secondary length;
an attenuator coupling the first portion of the secondary length to the second portion of the secondary length;
a bundling line coupled to the suspension line, wherein the bundling line is configured to secure the secondary length; and
a cutter configured to sever the bundling line and release the secondary length, wherein the attenuator is configured to sequentially release the first portion of the secondary length from the second portion of the secondary length.

2. The multi-staged suspension line length parachute of claim 1 , further comprising:
a canopy coupled to the suspension line; and
a bundling confluence coupled to the suspension line, wherein the bundling confluence comprises the cutter.

3. The multi-staged suspension line length parachute of claim 2 , wherein the first end of the secondary length is located proximate a suspension loop, and wherein the second end of the secondary length is located proximate a confluence loop.

4. The multi-staged suspension line length parachute of claim 3 , wherein the bundling line is located through the suspension loop and the confluence loop.

5. The multi-staged suspension line length parachute of claim 1 , wherein a first section of the attenuator comprises a first tensile strength, and wherein a second section of the attenuator comprises a second tensile strength greater than the first tensile strength.

6. The multi-staged suspension line length parachute of claim 5 , wherein the first section of the attenuator is located closer to the apex of the secondary length as compared to the second section of the attenuator.

7. The multi-staged suspension line length parachute of claim 5 , wherein the attenuator comprises a plurality of stitches, and wherein a pitch of a first set of stitches of the plurality of stitches is greater than a pitch of a second set of stitches of the plurality of stitches, and wherein the first set of stitches is located in the first section of the attenuator, and wherein the second set of stitches is located in the second section of the attenuator.

8. The multi-staged suspension line length parachute of claim 5 , wherein the first section of the attenuator comprises a first adhesive material including the first tensile strength, and wherein the second section of the attenuator comprises a second adhesive including the second tensile strength.
