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 a user selectable altitude 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 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.
