  • Publication number: 20240083586
    Abstract: A device for delaying the opening of a parachute, in particular a personal parachute or a cargo parachute, of a person jumping exiting an aircraft or of a cargo dropped from an aircraft, characterized by a delaying means designed to provide a connection between a drogue parachute connectable with a detachable connection to the aircraft and a parachute bridal line, said delaying means being movable from a delaying position in which no deployment of the parachute takes place, to a deployment position in which the parachute is deployed. A delay of the opening of the parachute, i.e. the time required for the movement from the delaying position to the deployment position, can be between 0.5 seconds and 2 seconds by suitable design of the delaying means. Advantageously, the deployment of the parachute is delayed and occurs outside a wake turbulence of the aircraft.

  • Patent number: 4898346
    Abstract: The reserve parachute is folded and disposed in a covering. A pilot chute overlies the reserve parachute outside of the covering. A disc overlies the pilot chute and bears against a compression spring maintained under compression by a single centrally positioned cord connected between the disc and a single release pin on the opposite side of the covering. The cord extends centrally through the compression spring and is connected centrally of the disc. Handling, packing and releasing of the reserve parachute and deployment of the pilot chute is thereby simplified.
