Abstract: A parachute release mechanism includes a housing, a strap hinge pin pivotably mounted to the housing, a cord coupled to the housing, and a cord tensioner coupled to the housing and coupled to the cord, wherein the cord tensioner is configured to impart a desired tension to the cord. The strap hinge pin is pivotable between a secured position and a released position, wherein in the secured position the strap hinge pin is configured to support a suspension strap for a payload and in the released position the suspension strap is enabled to disengage from the strap hinge pin. The cord is configured to retain the strap hinge pin in the secured position.

Abstract: A lever-lock release system is configured to releasably couple two objects together, for example a parachute and a payload. The lever-lock release system may comprise a first lever and a second lever, each rotatably coupled to a rigid base. When activated, the levers cascadingly rotate to release a first object and a second object. With these systems and related methods, various failure modes may be eliminated, such as undesired premature deployment of recovery parachutes during aerial delivery.

Abstract: A ring release system is configured to releasably couple a parachute to a payload. The ring release system may comprise a series of release rings affixed to a riser. At least one release ring has an associated retaining ring that surrounds the riser and is affixed to the riser on a back side. The retaining ring prevents stitching securing the release ring from being placed in peel when under stress, improving the reliability of the ring release system.

Abstract: The present disclosure provides a parachute comprising a fabric-based canopy and a crown area air inlet formed in the fabric-based canopy. The crown area air inlet may be aligned with areas of highest external pressure acting on an external surface of the canopy as the parachute inflates in order to increase a rate of inflation of the parachute.

Abstract: A parachute inlet control system is configured to provide an improved inflation profile for solo and/or clustered parachutes. An inlet parachute is coupled to a main parachute via a plurality of inlet control suspension lines and/or reefing rings. The inlet control suspension lines may be passed through the reefing rings and coupled to an anchor point below the main parachute. The inlet parachute is located in the inlet area of the main parachute, and causes the inlet of the main parachute to rapidly form a desirable shape. The inlet parachute and inlet control suspension lines function as a reefing system to prevent full inflation of the main parachute until a reefing cutter has functioned. In this manner, parachute failures, such as those due to leading and/or lagging parachutes in a parachute cluster, may be reduced or eliminated.

Abstract: A ring release system is configured to releasably couple a parachute to a payload. The ring release system may comprise an upper release ring, an intermediate release ring with a partially and/or completely flattened end, and a lower release ring having a J-shape. When activated, the release rings cascadingly separate to release the parachute from the payload. With these systems and related methods, larger payloads may be supported, the mass and size of the ring release system may be reduced as compared to prior systems, and various failure modes may be eliminated.

Abstract: Inserts for parachutes, for example modified cruciform parachutes, provide improved structural strength and reduced inflation times. An exemplary insert comprises a high-strength fabric coupled to center panels at a set of discrete points. The insert at least partially blocks airflow between the center panels, allowing the parachute canopy to inflate more rapidly. Via use of an insert, other components of a parachute, such as center panels, may be made of lighter, lower strength, and/or less expensive material without compromising the load-carrying capacity or reliability of the parachute.
