Which force acts toward the center of a turn in aerodynamics?

In the context of aerodynamics and circular motion, centripetal force is the key force that acts toward the center of the turn. When an aircraft is making a turn, the path it follows is circular, and to maintain this trajectory, a force is required to constantly pull the aircraft inward toward the center of the circle. This inward force is what we refer to as centripetal force, which can be generated by various factors, such as a combination of lift and bank angle.

It's important to distinguish centripetal force from centrifugal force. While centrifugal force is often perceived as acting outward, it is actually a perceived effect from the perspective of an observer in a rotating reference frame. This means that while a pilot or passenger may feel a force pushing them outward during a turn, this sensation is not a real force acting in that direction. Rather, the centripetal force is the actual force that is necessary for the aircraft to maintain its curved path.

In conclusion, during a turn, the force acting toward the center of the path of flight is the centripetal force, responsible for changing the direction of the aircraft and allowing it to navigate safely through the turn.
