Final answer:
During a sideslip, the force generated by the aircraft's vertical tail attempts to realign the aircraft with the direction of flight, following principles like Bernoulli's and those related to momentum conservation.
Step-by-step explanation:
When an aircraft is in a sideslip, it means that the aircraft's longitudinal axis is not aligned with its path of flight, causing air to strike the vertical tail at an angle, which generates a force. This force, acting on the vertical tail, will attempt to align the aircraft back to the streamlined condition. This force is similar to lift but acts horizontally and is a result of the angle of attack created by the sideslip. An important aspect to consider is the aerodynamic principles at play, such as Bernoulli's principle and the conservation of momentum principle, which explain how changes in velocity and air pressure around the tail surface generate the corrective force.
During flight, not only do airplanes sustain lift with their wings, but they also maneuver by banking, which involves tilting the plane so that part of the lift force provides the necessary centripetal force for turning. Similar to how a wing generates lift, the vertical tail can generate a lateral force during a sideslip, which helps bring the aircraft back in line. Specifically, the side force generated by the vertical tail is intended to counteract the sideslip angle, thereby stabilizing the aircraft's flight path.
