What does the '100' in the motor designation H100-5 stand for?

• A. It is the peak thrust in pounds of the rocket motor
• B. It is the rocket motor burn time in seconds
• C. It is the average thrust in Newtons of the rocket motor
• D. It is the manufacturer's retail price code

Answer: (C)

The designation uses the letter to indicate the total impulse class and the number after it to denote the motor’s average thrust in Newtons. The dash and trailing number show the delay time in seconds after burnout before deployment. So in H100-5, the 100 means the motor has about 100 newtons of average thrust, and the 5 indicates a 5-second delay. This is not the peak thrust in pounds, not the burn time, and not a price code.
