What is Structural Mass ?

The structural mass is a critical aspect of rocket design, as it directly impacts the overall mass of the rocket and its performance characteristics. Engineers strive to minimize the structural mass while ensuring that the rocket remains structurally sound and capable of withstanding the forces and loads experienced during launch and flight. Achieving an optimal balance between structural mass, propulsion efficiency, and payload capacity is essential for the success of a rocket mission.
