Aerotech adds a letter to the end of each engine denoting which of their three varieties of propellant mixtures it uses.
Aerotech makes engines with composite propellants, which they claim have up
to three times the energy of black powder by weight. They make disposable
engines in D through G size, and motors with reusable casings and replacable
propellant grains in D through M size. They also make a J size solid-liquid
hybrid which uses composite fuel and nitrous oxide liquid.
