How to Calculate Stability of a Model Rocket
Find the center of gravity of the rocket., Tie a four to six foot string around the rocket at this point., With the rocket suspended by the string, spin in a circle., Adjust the rocket to make it stable.
Step-by-Step Guide
-
Step 1: Find the center of gravity of the rocket.
This is the point at which you can balance the rocket on your finger. -
Step 2: Tie a four to six foot string around the rocket at this point.
When hung from the string, the rocket should be parallel to the ground. , If the rocket is stable, it will point forward in the direction you're turning. , There are two ways to do this.
Move the center of gravity forward by adding weight to the nose.
Move the center of pressure to the rear by enlarging or adding more fins. -
Step 3: With the rocket suspended by the string
-
Step 4: spin in a circle.
-
Step 5: Adjust the rocket to make it stable.
