For an aircraft with a right-hand propeller, what effect will slipstream rotation acting on the fin have?

In an aircraft with a right-hand propeller, the slipstream created by the rotating propeller influences the aircraft's stability and control characteristics. The propeller generates thrust and, as it spins, it also creates a slipstream that flows around the plane.

Specifically, for a right-hand propeller, the slipstream will rotate around the aircraft in a clockwise direction when viewed from the right side. This rotating slipstream hits the vertical stabilizer (fin) on the left side of the aircraft. The interaction between the rotating slipstream and the vertical stabilizer generates a side force, which in turn causes the nose of the aircraft to yaw to the left.

This yaw to the left is a critical aspect of understanding how the propeller's torque and the aircraft's design interact in flight, especially during certain phases like takeoff and climb when power settings are higher and the slipstream effect is more pronounced. Maintaining control against this yawing tendency may require right rudder input to counteract the effect, which is particularly important for pilots to manage during flight operations.
