Abstract

An evacuation assembly may comprise an evacuation slide and a first yoke coupled to the evacuation slide. The first yoke may comprise a first strap and a second strap. The first strap may be longer than the second strap. The evacuation assembly may optionally include a second yoke coupled to the evacuation slide. A first strap of the second yoke may be longer than a second strap of the second yoke.

Claims (25)

1. An evacuation assembly, comprising:

an evacuation slide; and

a deployment assembly coupled to the evacuation slide and configured such that during a deployment of the evacuation slide a forward portion of a toe end of the evacuation slide contacts an exit surface prior to an aft portion of the toe end of the evacuation slide, the deployment assembly comprising:

a first yoke coupled to the evacuation slide, the first yoke including a first strap and a second strap, wherein the first strap of the first yoke is longer than the second strap of the first yoke; and

a second yoke coupled to the evacuation slide, wherein a first strap of the second yoke is longer than a second strap of the second yoke.

2. The evacuation assembly of claim 1 , wherein the first strap of the first yoke is coupled to a forward portion of the evacuation slide and the second strap of the first yoke is coupled to an aft portion of the evacuation slide.

3. The evacuation assembly of claim 1 , wherein a ratio of a length of the first strap of the first yoke to a length of the second strap of the first yoke is from 6:5 to 4:1.

4. The evacuation assembly of claim 1 , wherein the first strap of the first yoke is between 6 inches and 9 feet longer than the second strap of the first yoke.

5. The evacuation assembly of claim 1 , wherein the second yoke is located closer to the toe end of the evacuation slide than the first yoke.

6. The evacuation assembly of claim 5 , further comprising:

a first releasable restraint coupled between the first yoke and the evacuation slide; and

a second releasable restraint coupled between the second yoke and the evacuation slide, wherein the first releasable restraint is configured to separate prior to the second releasable restraint during the deployment of the evacuation slide.

7. The evacuation assembly of claim 1 , wherein a first difference in a length of the first strap of the first yoke and a length of the second strap of the first yoke is greater than a second difference in a length of the first strap of the second yoke and a length of the second strap of the second yoke.

8. The evacuation assembly of claim 1 , wherein the deployment assembly further comprises a third yoke coupled to the evacuation slide, wherein a first strap of the third yoke and a second strap of the third yoke are approximately equal in length.

9. The evacuation assembly of claim 8 , wherein the third yoke is positioned closer to a head end of the evacuation slide than the first yoke and the second yoke.

10. A method of making an evacuation assembly, comprising:

coupling a first yoke to an evacuation slide, the first yoke comprising,

a first strap, and

a second strap, wherein the first strap is longer than the second strap;

coupling the first strap of the first yoke to a forward portion of the evacuation slide;

coupling the second strap of the first yoke to an aft portion of the evacuation slide; and

coupling a second yoke to the evacuation slide, wherein a first strap of the second yoke is longer than a second strap of the second yoke.

11. The method of claim 10 , wherein a ratio of a length of the first strap of the first yoke to a length of the second strap of the first yoke is from 6:5 to 4:1.

12. The method of claim 10 , wherein a first difference in a length of the first strap of the first yoke and a length of the second strap of the first yoke is greater than a second difference in a length of the first strap of the second yoke and a length of the second strap of the second yoke.

13. The method of claim 12 , further comprising coupling the second yoke closer to a toe end of the evacuation slide than the first yoke.
