High Powered Rocketry
Like model rocketry on steroids, high powered rocketry involves slightly larger rockets than model rocketry. High powered rockets also contain slightly more fuel and are capable of attaining slightly higher altitudes. High powered rocketry is the branch of the hobby of rocketry that falls directly between model rocketry and its more advanced, do-it-yourself older brother amateur rocketry.
This cross section of rocketry distinguishes itself from the other diverse segments in a very specific manner. A high powered rocket is one that is still relatively lightweight but that weighs a minimum of 1,500 grams and whose motor has a fuel capacity of at least 62.5 grams, as defined by the National Fire Protection Association. The same general construction methods as those used in model rocketry are employed in this segment too, with the exception that metal parts can now be added if required. Usually, however, high power rockets are made of plastic, wood, or cardboard.
Motors used by high powered rocketry hobbyists are generally pre-manufactured and may be either solid or hybrid varieties. Although there are no restrictions on the total weight of a high powered rocket, there are various restrictions as to the power capability of the motor. These impulse restrictions, however, are usually quite generous and allow for quite a high flying machine.
Although high power rocket motors are usually not available for over the counter purchase at your local hobby outlet, they are quite easy to obtain. There are a large number of high power certified modelers who make their machines available for purchase and shipment via online or mail-order retail. Certification to fly these models must also be obtained. This is offered by the NAR via a quick, three part certification program. Each rocket also comes with its own High Power Rocket Safety Code, which must be complied with at the time of launch.
To become an officially certified flyer of high power rockets, first of all you must apply for membership with the National Association of Rocketry. The NAR offers free high power rocket certification to all its adult members. A fascinating topic of study, this certification is generally quick and easy to obtain. Additionally, you can become a Trained Safety Officer and be qualified to assist in other peoples’ high power rocket launches in an official capacity as safety regulator. Both of these levels require a period of study terminated by a written exam.
If you are not yet an adult, there is a certification program for Junior High Power Rocket Participation. This is available for ages fourteen to seventeen and will qualify you to participate in high power rocket launches alongside an officially certified adult.
Not only does launching a high power rocket require certification, it also requires a lot more preparation time than your average model rocket launch. There are myriad details, both safety and otherwise, that must be attended to before the launch can be made. The field where the launch is to take place must be relatively larger than the minimum required for the launch of a smaller model rocket. This is simply because high power rockets produce greater thrust and must be given a wider berth and also because they can attain greater altitudes and need a wider plane of recovery.
The vast majority of high power rocket launches also require approval and clearance from the FAA. Both the date and location must be cleared to make sure that your launch does not interfere with the flight paths of any low-flying aircraft. Once you have received the FAA approved waiver stating that the surrounding area has been cleared of all air traffic, you may then proceed with the launch.
