At what total impulse and/or average thrust does a motor become categorized as high power?

A rocket motor is classified as high power based on specific criteria related to total impulse and average thrust. The correct answer indicates that a rocket motor qualifies as high power when it exceeds 160 Newton-seconds of total impulse or has an average thrust greater than 80 Newtons. This classification is significant in the field of rocketry as it defines the thresholds for safety regulations, licensing, and the type of certification required for operations involving high power motors.

Motors that meet or exceed these specifications are generally capable of producing significantly higher performance characteristics, which can affect flight stability, altitude, and overall aerodynamics. Therefore, adhering to these specific figures is essential for aligning with safety standards and operational guidelines within the rocketry community.
