Which rocket engine will lift my rocket safely?When buying a rocket kit, use the manufactures recommended motors.Use this rule of thumb when scratch building your own design. To figure out if a particular rocket motor can safely lift your rocket, divide the number between the letter and the dash by 4.48. This will convert the average thrust from newtons to pounds. You will need at least 6 times the amount of thrust as your rocket weighs with the motor installed. 9 divided by 4.48 = 2.01 2.01 divided by 6 = 0.33 Lbs Your rocket should weigh no more then .33 Lbs or 5.33 ozs. |
