Weight - The total weight of the rocket, with motor, at lift-off.
TTW Average - The average thrust-to-weight ratio of the rocket.
TTW Peak - The peak thrust-to-weight ratio of the rocket.
Accel - The maximum acceleration experienced by the rocket.
Speed - The maximum speed experienced by the rocket.
Rod Len - The minimal rod/rail length for the rocket to reach a safe speed (9 m/s) for free flight.
Optimal Delay - The optimal delay time (equal to the time from burnout to apogee).
Altitude - The altitude at apogee.
Note: These simulation results should be used with caution. Always double-check to ensure that your flight will be safe.
The Rocket Motor Guide helps you choose the right motor to use in your rocket by running a simulation using each of the motors in the RocketReviews.com motor database.
