Roll Program – Definition & Detailed Explanation – Rocketry & Propulsion Glossary
I. What is a Roll Program? A roll program is a maneuver used in rocketry to control the orientation of a rocket during flight. It involves rotating the rocket around its longitudinal axis, causing it to roll along its flight path. This rotation can be controlled and adjusted to achieve specific objectives during the flight … Read more
