What Is High Power Rocketry?
In essence, take everything you know about model rocketry and make it BIGGER!
If you like big smoke, big noise and big rockets; then high power is for you.

WHAT QUALIFIES AS HIGH POWER?
Any rocket which is heavier that 1.5 kg in weight or flies with a total impulse of greater than 160 N-s (the size of a "G" motor), is by definition a high power rocket. Under this definition, even a cluster of two G-sized motors would make the rocket "High Power". But they get much, much bigger than that.
Motor sizing in high power follows the same alphabetic lettering system used in model rocketry. Individual, commercially available, high power motors start with impulse class "H" and continue up to "O"; with each step of the alphabet representing a doubling of the motor's total impulse. An "O" class motor would be the equivalent total impulse of a cluster of 256 "G" motors!
WHO CONTROLS HIGH POWER?
High Power Rocketry is a controlled activity in Canada.
Purchase and use of high power rocket motors is controlled.
Launching of high power rockets is controlled through the Government of Canada Launch Safety Office. It requires the filing of an "Application to Launch a High Power Rocket" and the approval of Transport Canada. You must either be certified to launch a particular "level" of high power rocket, or attempting a certification attempt at that level. As such, high power launch events are always planned, controlled and scheduled events.
To fly high power rockets, you must be a member of the Canadian Association of Rocketry.
THE CERTIFICATION PROCESS
In Canada, Certification for High Power Rocketry consists of four progressive levels.
Level 1 allows the purchase and use of "H" impulse class motors.
Level 2 allows the purchase and use of "I" impulse class solid motors and hybrid rocket motors.
Level 3 allows the purchase and use of "J", "K" and "L" impulse class solid motors and hybrid rocket motors.
Level 4 allows the purchase and use of "M", "N" and "O" impulse class solid motors and hybrid rocket motors.
To achieve "certification" in any level you must demonstrate the ability to build, launch and safely recover your rocket.
HOW DO I GET THERE?
A number of MRG members have successfully achieved Level 4 status. They can guide you through the certification process of high power rocketry. But remember, it is not just the destination, but the journey itself. Join the MRG, and have fun; the sky is the limit!
