Abstract
A hydraulic mechanism is positioned within the drogue bridle of a parachute system. The hydraulic link is slowly moved by tension on the drogue bridle to operate a release. The release operates to release the drogue chute and to deploy the main chute. The movement of the hydraulic link provides a time delay between deployment of the drogue chute and the main chute to allow the load to stabilize before deployment of the main chute.
Claims14
A parachute system comprising:
- a drogue chute;
- a main chute;
- and
- a hydraulic timer delayed release for deploying the main chute a predetermined period of time after deployment of the drogue chute.
1 more element
A method of deploying chutes in a parachute system having a drogue chute and a main chute, the method comprising the steps of:
- deploying the drogue chute;
- delaying a predetermined period of time using an hydraulic timer;
- and
- deploying the main chute after the predetermined period of time using a release operated by the hydraulic timer.
1 more element
A parachute system comprising:
- a drogue chute;
- a main chute;
- a bridle, connecting the drogue chute to the main chute;
- a hydraulic timer delayed release, for deploying the main chute a predetermined period of time after deployment of the drogue chute, and wherein the hydraulic timer delayed release is actuated by the tension on the bridle, and wherein the hydraulic timer delayed release includes a hydraulic link positioned in the bridle which moves from an engaged position to a disengaged position under tension of the bridle;
- and
- a release mechanism operable by the hydraulic link being moved into the disengaged position, for deploying said main chute.
