What is the specification for a class 2 rocket?

A class 2 rocket is defined by its total impulse. Specifically, the specification states that a class 2 rocket has motors providing a total impulse of less than 40,960 Newton-seconds (N-s). This measurement reflects the overall thrust performance of the rocket's motors and is crucial for categorizing the rocket in relation to safety regulations and operational parameters.

Total impulse is a key factor in rocketry, as it determines the rocket's performance capability during flight. A class 2 designation indicates a level of impulse that is suitable for certain types of amateur rocketry, allowing for a range of experimental and hobbyist applications while still maintaining safety standards established by governing bodies like the Tripoli Rocketry Association.

Other options present different criteria that do not accurately reflect the total impulse requirement for class 2 rockets. For instance, specifying a weight limit or restricting the rocket to a single motor does not align with the total impulse classification that defines class 2 rockets. Understanding this total impulse specification is vital for anyone engaged in rocketry, as it influences both the design and safety of rocket launches.
