Model rocket motor classification - Wikipedia
Motors for model rockets [1] and high-powered rockets [2] (together, consumer rockets) are classified by total impulse into a set of letter-designated ranges, from ⅛ A up to O. The total impulse is the integral of the thrust over burn time.
Why can't amateur rockets reach space on an O motor?
2014年12月21日 · A O rocket could achieve the altitude if optimized and configured properly (and especially absent a recovery system). HOWEVER going to space is easy, staying there is not. Read this for some clarification (at least something the …
Rocket Motor Information - National Association of Rocketry
In a typical hobby store, you will find motors in power classes from 1/8A to D. However, E, F, and some G motors are also classified as model rocket motors. Modelers certified for high power rocketry by the NAR can purchase motors ranging from G to O. Each letter represents twice the power range of the previous letter total.
Model Rocket Engine Sizes and Classifications
Model rocket engines are classified by engine sizes A through O, with the higher letters being more powerful. The numbers associated with each engine letter describe the burn duration and delay before firing an ejection charge.

2 stage O motor to space? - Model Rocketry Forums
2023年6月29日 · I am currently wondering the feasibility of launching a two stage rocket into space with two Aerotech O5500 motors. RASaero predicts 360k and mach 5.1 on the sustainer. Each stage would have a 4 inch diameter and be actively separated from one another. Opinions are very much appreciated.
Aerotech Rocketry O5500 Propellant X DMS Rocket Motor
The motor delivers 21,384 N-sec (4,808 lb. sec) of total impulse in 4.03 seconds making it ideal for extreme high-altitude attempts (including two-stage flights to the edge of outer space!) and sport flights in heavy weight rockets.

Rocketry Basics
Since each letter doubles the size of the previous letter designation, an "O" motor is 4096 times larger than a "C" engine that is most commonly used in model rocketry. The "O" engine price approaches $1000 and could lift a rocket to five miles.
