Rocketry Terms

Model Rocketry

As a model rocket, we usually consider all rockets based on the internations safety code according to NFPA 1122 using engines in the A-G range (up to 160 Ns).

This means using lightweight, breakable components and no basic metal parts. Examples are kits from Estes or Quest.

Additonal, we differ between Low- and Midpower model rockets. Lowpower is considered between A-D, while Midpower is within the E-G range.

High Power Rocketry

High-Power Rockets are, in general, based on usual model rocket building technics but are constructed a little 'bigger' using engines in the H-O range.

Like model rockets, they are build based on the safety code which means no basic metal parts and lightweight building components which will break in case of an accident. Due to the nature of this models they are constructed stronger than standard model rockets, e.g. using larger body tubes, but they are still using the same safety features. Examples are kits from AeroTech.

Amateur Rocketry

Everything which goes beyond standard model rocketry or high power rocketry can be considered as amateur  or semi-professional rocketry.

Sometimes it is called experimental rocketry, however, this is a little bit incorrect since every rocket is an experiment and therefore an 'experimental' rocket. In general, the criterias are: using different materials than described in the safety code such as basic metal parts, non-breakable body tubes, e.g. made from plastic material, and high-impulse engines starting at H.

For this kind of rockets, the safety code is no longer valid, however, to prevent accidents, specific safety rules and laws must be followed, especially if flown in any public event.
