Abstract

A parachute is coupled to a rocket where the parachute is extracted by having the rocket pull on the parachute. A parachute strap couples the parachute to an aircraft where at a first point in time, a first section of the parachute strap and a second section of the parachute strap are both secured independently of each other. At a second point in time, the second section of the parachute strap is still secured while the first section of the parachute strap is released where the released first section of the parachute strap gradually becomes taut as the parachute is extracted.

Claims (76)

1. A system, comprising:

a rocket;

a parachute, wherein the parachute is coupled to the rocket and the parachute is extracted by having the rocket pull on the parachute; and

a parachute strap that couples the parachute to an aircraft, wherein:

at a first point in time, a first section of the parachute strap and a second section of the parachute strap are both secured independently of each other,

wherein the first section of the parachute strap and the second section of the parachute strap are sewn to a fabric backing, including a parachute bag, using one or more pieces of string; and

at a second point in time, the second section of the parachute strap is still secured while the first section of the parachute strap is released where the released first section of the parachute strap gradually becomes taut as the parachute is extracted.

2. The system of claim 1 , wherein:

the first section of the parachute strap and the second section of the parachute strap do not overlap;

the first section of the parachute strap is bound by a first set of one or more bindings that tie the first section of the parachute strap to a surface; and

3. The system of claim 1 , wherein:

the first section of the parachute strap and the second section of the parachute strap do not overlap;

the first section of the parachute strap is between: (1) a first point along the parachute strap which a first point-to-point tie connects to a first anchor point and (2) a second point along the parachute strap which a second point-to-point tie connects to a second anchor point; and

the second section of the parachute strap is between (1) the second point along the parachute strap and (2) a third point along the parachute strap which a third point-to-point tie connects to a third anchor point.

4. The system of claim 1 , wherein the first section of the parachute strap and the second section of the parachute strap are attached to an interior surface of a fuselage using one or more pieces of covering.

5. The system of claim 1 , wherein the first section of the parachute strap and the second section of the parachute strap are attached to an interior surface of a fuselage using one or more pieces of covering, including one or more of the following: tape, an adhesive, or a composite.

6. The system of claim 1 , wherein the parachute strap includes steel.

7. The system of claim 1 , wherein the parachute strap is stronger towards a fuselage than towards the parachute.

8. A method, comprising:

providing a rocket and a parachute, wherein the parachute is coupled to the rocket and the parachute is extracted by the rocket pulling on the parachute; and

providing a parachute strap that couples the parachute to an aircraft, wherein:

at a first point in time, a first section of the parachute strap and a second section of the parachute strap are both secured independently of each other,

wherein the first section of the parachute strap and the second section of the parachute strap are sewn to a fabric backing, including a parachute bag, using one or more pieces of string; and

at a second point in time, the second section of the parachute strap is still secured while the first section of the parachute strap is released where the released first section of the parachute strap gradually becomes taut as the parachute is extracted.

9. The method of claim 8 , wherein:

the first section of the parachute strap and the second section of the parachute strap do not overlap;

the first section of the parachute strap is bound by a first set of one or more bindings that tie the first section of the parachute strap to a surface; and

the second section of the parachute strap is bound by a second set of one or more bindings that tie the second section of the parachute strap to the surface.

10. The method of claim 8 , wherein:

the first section of the parachute strap and the second section of the parachute strap do not overlap;

the first section of the parachute strap is between: (1) a first point along the parachute strap which a first point-to-point tie connects to a first anchor point and (2) a second point along the parachute strap which a second point-to-point tie connects to a second anchor point; and

the second section of the parachute strap is between (1) the second point along the parachute strap and (2) a third point along the parachute strap which a third point-to-point tie connects to a third anchor point.

11. The method of claim 8 , wherein the first section of the parachute strap and the second section of the parachute strap are attached to an interior surface of a fuselage using one or more pieces of covering.

12. The method of claim 8 , wherein the first section of the parachute strap and the second section of the parachute strap are attached to an interior surface of a fuselage using one or more pieces of covering, including one or more of the following: tape, an adhesive, or a composite.

13. The method of claim 8 , wherein the parachute strap includes steel.

14. The method of claim 8 , wherein the parachute strap is stronger towards a fuselage than towards the parachute.

15. A system, comprising:

a rocket;

a parachute, wherein the parachute is coupled to the rocket and the parachute is extracted by having the rocket pull on the parachute; and

a parachute strap that couples the parachute to an aircraft, wherein:

at a first point in time, a first section of the parachute strap and a second section of the parachute strap are both secured independently of each other,

wherein the first section of the parachute strap and the second section of the parachute strap are attached to an interior surface of a fuselage using one or more pieces of covering; and

at a second point in time, the second section of the parachute strap is still secured while the first section of the parachute strap is released where the released first section of the parachute strap gradually becomes taut as the parachute is extracted.

16. The system of claim 15 , wherein:

the first section of the parachute strap and the second section of the parachute strap do not overlap;

the first section of the parachute strap is bound by a first set of one or more bindings that tie the first section of the parachute strap to a surface; and

the second section of the parachute strap is bound by a second set of one or more bindings that tie the second section of the parachute strap to the surface.

17. The system of claim 15 , wherein:
