PML CPR-3000
If you want to fly high altitude rockets in a small field, you'll need it!
What is CPR? CPR is an altimeter based, two step parachute deployment system. Using a dual-deployment altimeter, the first chute (a small drogue) is deployed at apogee allowing for a fast but controlled descent. At approximately 400/800 feet, (user selectable) the altimeter fires a second charge deploying the main chute allowing for a soft landing.
The altimeter is centrally located in a special compartment within the main airframe. The drogue chute is ejected from a split-point in the airframe just above the fin/motor section while the main is ejected at the nose cone. Both chutes are deployed using our exclusive Piston Ejection System.
Just two simple yet strong anodized aluminum parts hold the altimeter and ejection charge cylinders as a self contained unit. Prep the assembly on a table, slip it into your rocket, screw the airframes together, and launch. Once assembled, the altimeter/charge cylinder assembly can be easily moved to another CPR3000 rocket, making it easy (and cost-effective, since you only need one altimeter) to fly CPR3000.
What is CPR3000? The most complete Close Proximity Recovery System ever!
No need to purchase separate ejection systems, external safety switch, or drogue chute!
Also includes a 16 page, fully illustrated, comprehensive assembly and user manual. These
systems are perfect for retro-fitting into your existing rockets or for incorporating into
your new designs.
Here’s what you get:
| A: A small, yet very robust (rated at 6 amps) external
safety switch is mounted to the airframe in the area between the two centering rings. B: The CPR-3k system can be installed into any airframe diameter by simply using the appropriate centering rings and airframe coupler (included). |
F: This coupler adds a little strength to the joint but
primarily acts to align the IDs of the two airframe sections. G: The precision machined, aluminum threaded airframe coupler screws over the threaded sleeve to lock the airframes together and holds the altimeter/charge assembly within the altimeter tube. |
C:The soft vinyl charge cap fits snugly over the charge cylinder. No need for tape.
They are inexpensive and will be sold by the dozen. (4) are included with the kit.
D:The charge cylinder snaps firmly into the charge holder and will not require tape to
hold it. This design is intended to be used with electric matches and BP and can be
re-used indefinitely. Optional Charge Cylinders are available for flash bulb use.
E:The mounts are designed specifically for the new PML Co-Pilot and the P6 altimeters.
Optional mounts are available for the P5 and ALTS-25 altimeters. Some re-work of the
mounts may be needed for other brand altimeters.
