Motors for model rockets and high-powered rockets (together, consumer rockets) are classified by total impulse into a set of letter-designated ranges, from â…›A up to O. The total impulse is the integral of the thrust over burn time. See more
In many countries, the sale, possession, and use of model rocket motors is subject to governmental rules and regulations. High-power rockets in the United States are only federally regulated in their flight guidelines by the FAA. These regulations are codified in FAA … See more
1982An attempt was made by motor manufacturers in 1982 to further clarify the motor code by writing the total impulse in newton-seconds before the code.1990sIn the late 1990s, the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives began requiring that individuals obtain a Low Explosives Users Permit (LEUP) to possess and use high-powered motors.2000On February 11, 2000, Tripoli Rocketry Association and the National Association of Rocketry filed suit in the United States District Court for the District of Columbia claiming that the BATF applied onerous and prohibitive civil regulations against sport rocketry hobbyists due to the Bureau's improper designation of ammonium perchlorate composite propellant (APCP) as an explosive.2009In 2009, the court ruled in favor of the hobby organizations and ordered the BATF to remove APCP and other slow burning materials from its list of regulated explosives.1958The very first model rocket motor certified was by Model Missiles Inc. (Orville Carslile). Circa 1958.1985The very first high-power rocket motor certified was by U.S. Rockets (Jerry Irvine). Circa 1985.1970The very first APCP propellant model rocket motor made was by Rocket Development Corporation (Irv Wait). Circa 1970.The largest vendor of model rocket motors in the world is Estes Industries. The largest vendors of high-power rocket motors in the world are Cesaroni Technology Inc. See more

Rocket technology can combine very high thrust (meganewtons), very high exhaust speeds (around 10 times the speed of sound in air at sea level) and very high thrust/weight ratios (>100) simultaneously as well as being able to operate outside the atmosphere, and while permitting the use of low pressure and hence lightweight tanks and structure.
