Aircraft will interact with air during flight and produce drag, lift and lateral force. Among them, the resistance is the air resistance when the plane is moving forward, which will cause the plane to consume more fuel and reduce the flight speed. Lift is the upward pushing force on an airplane, which enables the airplane to take off against gravity and maintain its flight attitude. Lateral force is the lateral thrust generated when the aircraft turns in the air, which can change the attitude and course of the aircraft.
In order to reduce the drag of aircraft, designers usually adopt various aerodynamic measures. One of the common methods is to install the spoiler of the aircraft wing. These spoilers are usually triangular or arc-shaped and located at the leading edge or trailing edge of the wing. When the airflow passes through the spoiler, due to its special shape and structure, the airflow will be guided in different directions, thus changing the speed and direction of the airflow. In this way, the spoiler can reduce the air resistance of the aircraft and improve the flight efficiency and economy.
In addition to reducing drag, the wing spoiler can also improve the lift distribution of the aircraft. By adjusting the shape and position of the spoiler, designers can make the lift of the aircraft more evenly distributed on the whole wing, thus improving the stability and maneuverability of the aircraft. This is especially important for large passenger aircraft, because they need to maintain a stable flight state under different flight conditions.
However, it should be noted that the design and installation of aircraft wing spoiler need to be strictly calculated and tested. Their size, shape and position need to be accurately controlled to ensure that their influence on the aerodynamic performance of aircraft is positive rather than negative. In addition, the spoiler of the aircraft wing also needs to be inspected and maintained regularly to ensure its normal operation and good performance.
