Abstract

A recovery parachute assembly may comprise a container comprising an open base end, a parachute packed within the container, a plurality of riser lines and suspension lines packed within the container and proximate the open base end, a tray including a lip configured to receive the open base end of the parachute container, and a first standoff block coupled to the tray, wherein the first standoff block compresses at least one of the riser lines or suspension lines into the base end of the container and away from the tray, wherein the first standoff block defines a channel between the lip of the tray and the first standoff block, wherein the channel includes a plurality of drain holes formed along a distal edge of the tray.

First claim

What is claimed is:

1. A recovery parachute assembly, comprising:
a parachute container comprising an open base end;
a parachute packed within the container;
a plurality of riser lines and suspension lines packed within the container and proximate the open base end;
a tray including a lip configured to receive the open base end of the parachute container; and
a first standoff block coupled to the tray, wherein the first standoff block compresses at least one of the riser lines or suspension lines into the base end of the container and away from the tray,
wherein the first standoff block defines a channel between the lip of the tray and the first standoff block,
wherein the channel includes a plurality of drain holes formed along a distal edge of the tray.

2. The recovery parachute assembly of claim 1 , further comprising a skirt coupled to the container.

3. The recovery parachute assembly of claim 1 , wherein the lip defines a first basin and a second basin of the tray, wherein the first standoff block is coupled within the first basin and a second standoff block is coupled within the second basin.

4. The recovery parachute assembly of claim 3 , further comprising a third standoff block coupled within the first basin, wherein the first standoff block and the third standoff block define an interblock channel therebetween.

5. The recovery parachute assembly of claim 2 , wherein the skirt includes a flange portion and a deflector portion.

6. The recovery parachute assembly of claim 2 , wherein the skirt extends outward of the container and over the lip.

7. The recovery parachute assembly of claim 2 , wherein the skirt and the container are monolithic and wherein the first standoff block and the tray are monolithic.

8. An ejection seat for an aircraft, comprising:
a seat bucket;
a seat back coupled to the seat bucket;
a propulsion system; and
a parachute container comprising an open base end;
a parachute packed within the container;
a plurality of riser lines and suspension lines packed within the container and proximate the open base end;
a tray including a lip configured to receive the open base end of the parachute container, wherein the tray is coupled to the seat back; and
a first standoff block coupled to the tray, wherein the first standoff block compresses at least one of the riser lines or suspension lines into the base end of the container and away from the tray,
wherein the first standoff block defines a channel between the lip of the tray and the first standoff block,
wherein the channel includes a plurality of drain holes formed along a distal edge of the tray.

9. The ejection seat of claim 8 , further comprising a skirt coupled to the container.

10. The ejection seat of claim 8 , wherein the lip defines a first basin and a second basin of the tray, wherein the first standoff block is coupled within the first basin and a second standoff block is coupled within the second basin.

11. The ejection seat of claim 10 , further comprising a third standoff block coupled within the first basin, wherein the first standoff block and the third standoff block define an interblock channel therebetween.

12. The ejection seat of claim 9 , wherein the skirt includes a flange portion and a deflector portion.

13. The ejection seat of claim 9 , wherein the skirt extends outward of the container and over the lip.

14. The ejection seat of claim 9 , wherein the skirt and the container are monolithic and wherein the first standoff block and the tray are monolithic.
