If not, just plug the variables into this calculator and get the instant answer to your question. WebA model rocket is launched straight upward with an initial speed of 50.0 m/s. We can also try to use a rocket simulator, which is probably the best way to determine the altitude because it takes into account many factors that affect the flight of a rocket, such as the wind velocity and direction, and the launch rod inclination. The letter C in our example motor above tells us that there is anywhere from 5.01 to 10.0 N-sec of total impulse available in this motor. Nose cones were tested on the same model: 1st stage propellant burns out, booster apogee, 2nd stage ignition, The rocket movement stopped; the camera was separated from the rocket. For Class 2 and larger rockets, you must apply for a waiver from the FAA using the procedures described on the Filing For FAA Launch Authorization webpage. Therefore, the effective rod length for this rocket is only 912013=58 cm. The quintessential Estes ready to fly beauty. Includes pressure-sensitive decals and quick-release engine mount. Well take a look and remove the review if it doesnt follow our guidelines. Note, however that the average thrust printed on the motor may differ greatly from the actual average thrust of the motor. Often their labels are printed in a different color to help prevent you from using them in a typical rocket. By the way, we do not use the word fuel when we talk about model rockets because the word propellant means both fuel and oxidizer.
