What is the maximum launch angle from vertical for a high-power rocket?

The maximum launch angle from vertical for a high-power rocket is critical for maintaining stability and performance during flight. A launch angle that is too steep can lead to instability and subsequent loss of control, while a shallow launch angle may not allow sufficient thrust to overcome gravitational forces efficiently.

The choice of a 20º launch angle strikes an ideal balance between the need for a stable trajectory and the ability to achieve the necessary altitude and velocity. At this angle, the rocket can maintain a robust aerodynamic path, minimizing side loads that could destabilize the rocket. It also allows for effective recovery system deployment and descent control after reaching apogee.

Lower angles, such as 10º and 15º, may not provide the optimal performance needed for high-power rockets to clear obstacles or achieve desired altitudes, while higher angles like 25º could increase the risk of aerodynamic instability and drag, ultimately impacting the flight duration and safety. Thus, the 20º angle is generally considered the maximum for effective launch performance, aligning with safety protocols and optimal design principles in rocketry.
