Which of the following is NOT an example of rocket control and stability systems?

• A. Vanes
• B. Gimbaled nozzles
• C. Fuel tanks
• D. Attitude control

Answer: (C)

The correct choice is fuel tanks, as they do not contribute to the control and stability of a rocket. Rocket control and stability systems are specifically designed to manage the trajectory, orientation, and stability of a rocket during flight. Vanes, for instance, are devices used to redirect airflow to create torque, effectively allowing a rocket to change its orientation. Gimbaled nozzles involve mounting the engine nozzles on a pivot, so they can be angled during flight to alter the direction of thrust, helping to steer the rocket. Attitude control systems utilize various inputs, such as reaction wheels or thrusters, to maintain or change the rocket's orientation in space. Each of these components plays a critical role in ensuring that the rocket can maneuver and maintain its intended flight path, while fuel tanks serve a different purpose by storing propellant rather than contributing to the rocket's control system.
