Assertion (A): Aircraft wings are slotted to control separation of boundary layer especially at large angles of attack.
Reason (R): This helps to increase the lift and the aircraft can take off from, and land on, short runways.
Explanation:
Introduction:
Aircraft wings are designed to generate lift, which is the force that opposes the weight of the aircraft and allows it to stay in the air. The lift is primarily generated by the difference in air pressure between the upper and lower surfaces of the wing. To maximize lift, it is important to prevent the separation of the boundary layer, especially at large angles of attack. Slotted wings are one of the methods used to control boundary layer separation.
Explanation of Assertion (A):
The assertion states that aircraft wings are slotted to control separation of the boundary layer, especially at large angles of attack. The boundary layer is the thin layer of air that flows over the surface of the wing. At high angles of attack, the boundary layer can separate from the wing surface, leading to a loss of lift and increased drag, which can be dangerous for the aircraft.
The slots in the wing are designed to control the airflow over the wing surface and prevent boundary layer separation. These slots allow high-energy air from the upper surface of the wing to be injected into the boundary layer, energizing it and preventing separation. By controlling the boundary layer separation, the lift can be increased, allowing the aircraft to maintain its flight, even at large angles of attack.
Explanation of Reason (R):
The reason states that slotted wings help to increase the lift and enable the aircraft to take off and land on short runways.
When the boundary layer separates from the wing surface, the lift generated by the wing decreases, and the aircraft may lose the ability to maintain flight. By preventing boundary layer separation using slotted wings, the lift can be increased, allowing the aircraft to generate more lift at large angles of attack. This increased lift enables the aircraft to take off and land on short runways, as it can generate the necessary lift even at low speeds.
Conclusion:
Both the assertion and reason are individually true. The slots in the wing are indeed used to control the separation of the boundary layer, especially at large angles of attack. This, in turn, helps to increase the lift, enabling the aircraft to take off and land on short runways. Therefore, Option C is the correct answer.
Reason (R): This helps to increase the lift and the aircraft can take off from, and land on, short runways.
