Must be 18 years of age to purchase “D” and “E” size engines. For example, a motor with the code C6-5 has the power of a C class engine. Level 2 allows the purchase and use of I impulse class solid motors and hybrid rocket motors. This article is from the Model Rockets FAQ, by Wolfram von Kiparski with numerous contributions by others. (c) Class 3—Advanced High-Power Rocket means an amateur rocket other than a model rocket or high-power rocket. In addition to motor size, Model Rocket classification also takes into account the size of the rocket itself. The impulse class is a letter code assigned to a range of total impulse with each letter being twice as powerful as the previous. Estes Pro Series II 24mm Motor Retainer Set. Most importantly, you can download thrust curves for use with rocket flight simulators (RockSim and OpenRocket among others). Black powder rocket motors are only commonly produced up to Class E. Each class's upper limit is double the upper limit of the previous class. If one motor has a higher total impulse than another, it is said to have “more power.” The usefulness of the total impulse number has led to a simple way of classifying model rocket motors (professional rockets, like the space shuttle are not classifi ed this way). Model rockets don’t have regulations that limit altitude, but rather the weight of the rocket and amount of propellent. 99. The second category is "Cluster". All black powder (BP) motors… $119.99. 1.6 What do the letters and numbers on a model rocket motor mean? If you are interested in rocket systems you need to download files.

In the U.S. (which where the system of rules that I am most familiar with are enforced), the purchase and use of rocket motors are divided into two categories, one with its own sub-categories. Rocket Motor Data. Total impulse is: 1115.0 Newton-seconds. Since the early 1960’s rocket motors have been classifi ed by The first number indicates the average thrust in Newtons. The Estes Igniter Plug makes engine ignition extremely reliable. Classes A through G are for model rocketry, while classes H through O are for high power rocketry and require special certification and licensing. 109. (c) Class 3—Advanced High-Power Rocket means an amateur rocket other than a model rocket or high-power rocket. Hence, the motor in the figure is a class D total impulse engine with an average thrust of 12 Newtons and a time delay of 5 seconds. The answer depends on a couple of factors: the weight of your rocket and the motor you’re using. Rocketry organizations recognize five classifications of rockets, as outlined below, based on motor size or propellant weight. "Model Rocketry" rockets only use motors that are G and below. The modeler must demonstrate his ability to build and fly a rocket containing at least one H or I impulse class motor. Answers: 2 Get Other questions on the subject: Physics.
