What is the effect of accelerated slip-stream?

The effect of accelerated slipstream is primarily characterized by the difference in lift created by the prop wash over the wing. When a propeller rotates, it generates a slipstream of high-velocity air that flows over the wings of the aircraft. This phenomenon is particularly pronounced in multi-engine aircraft, where the slipstream can enhance the lift on the wing located on the same side as the rotating propeller, leading to improved aerodynamic performance.

This interaction between the slipstream and the wing's airfoil generates a higher angle of attack on the wing due to the increased airflow and pressure differential created by the prop wash. Consequently, this can improve the wing’s lift characteristics during various flight maneuvers, especially during takeoff and climb. Understanding the role of accelerated slipstream is essential for managing aircraft performance and handling, particularly in multi-engine operations where asymmetrical thrust can significantly affect the aircraft’s behavior.

The other choices, while related to flight performance, do not accurately represent the specific effect of accelerated slipstream as it pertains to the prop wash's influence on lift.
