"The Dura-Chutes are the highest quality rocket parachutes in the industry."
If you have seen PML`s Dura-Chute parachutes out on the field, you know that we have the best parachutes on the market! Highest quality, professionally made, multipanel, 15 degree conical design, rip-stop nylon construction.
Starting with the PAR-60 (60" diameter), we add heavy duty reinforcement webbing to each seam of the chute. This includes the seams between every panel, the skirt, the apex, and cord attach points. These are extemely rugged chutes!
"PML chutes were judged the highest in overall ratings of strength, quality, and appearance as published in the December 1998 HPR Magazine report The Great Parachute Driftoff."
All PML parachutes have a spill hole at the apex to reduce sway and drift. Approximate sizes (they may vary slightly) for the spill holes are shown below.

The Piston System:
The PML Piston ejection system is the most reliable and effective ejection system ever developed for high power rocketry. You will never again need to stuff your rocket full of wadding or fiberglass insulation. Partial ejection caused by blow-by as well as burnt parachutes will become a thing of the past. Also, the nylon/rayon piston retaining strap is heat resistant and vastly reduces the zip cord effect encountered during early or late ejection by spreading the force over a much wider area than rope or cable. (The system must be incorporated during initial assembly).
How It Works
The operation of the piston system is quite simple. The piston sits in the airframe "over" the motor and "under" the parachute. It is attached to the motor mount via the nylon strap which is epoxied to both the motor mount and the piston itself. When the ejection charge goes off, the pressurization between the motor and the piston bottom pushes the piston upward, which separates the rocket and pushes the chute out. That`s all there is to it. No special prep needed, nothing to do...just push in the piston, load the chute, and you`re done.

Also offered are Tubular Nylon Shock Cord, as well as various sizes of nylon recovery strap used in our piston systems. Tubular Nylon is many times stronger than elastic and is used in place of elastic for shock cord tethering. See our Complete FAQ on the FAQ Page for details on shock cord and strapping selection.
