BirdStrike Preventer

Abstract

The present invention is a 'bird collision prevention device' that utilizes airflow through fluid dynamics and is mounted on the front of an aircraft engine, and is composed of the following important elements. The device, composed of a hole-cone (2) and a frame (5), is characterized by using the airflow generated during aircraft operation to push birds away from the engine to prevent collisions, and by reducing induced drag through a winglet function to ensure safe operation. As a result, there is a significant economic effect in reducing economic losses caused by bird collisions, such as engine damage, flight delays, and repair costs. ㆍ Hole-Cone: The front of the cone (2) has a large hole and is cone-shaped, and is mounted on the front of the aircraft engine. The slanted surface of the cone performs the function of dispersing airflow and generates a wake, causing the air to be pushed outward. The amount of airflow pushed outward (force) is proportional to the aircraft speed and is converted into a powerful force that pushes away birds or foreign objects at the speed of takeoff and landing, preventing collision with the engine. ㆍ Frame: The frame (5) supporting the cone more efficiently fixes the shape of the cone. The curved shape of the frame provides the effect of reducing induced drag and smoothly disperses the airflow to form an airflow of a given intensity. A fin is installed in the middle of the frame and at the part where the cone (2) is joined, which serves to reduce vortices. The curved frame (3-1) can be operated more effectively as increasing the curvature generates a large amount of airflow. The streamlined fin (7) and the wide frame panel (3) have the characteristic of acting as winglets that control the airflow and efficiently mitigate air vortices. ㆍ Winglet: The combined structure (3) of the cone and the frame acts as a winglet, reducing induced drag generated by the cone, increasing fuel efficiency, and helping the aircraft fly stably. The frame of the part (3) where the cone is joined is designed with a wide curve and has protruding streamlined fins (7) arranged thereon. This increases fuel efficiency and improves stability during flight. The winglet controls the airflow more efficiently and contributes significantly to the stability of the aircraft. The invention relates to a collision avoidance device in which the airflow generated during flight between the inclined surface of the cone and the frame is converted into a pushing force, thereby maximizing the role of pushing birds and foreign objects away from the engine. • Material: The cone and frame (Fig. 2, Fig. 7) are characterized by their ability to prevent physical collisions on their own. They are manufactured using lightweight, high-strength materials such as titanium, aluminum, and composite materials. These materials minimize the weight of the device and minimize the impact on the aircraft's performance. Additionally, the device possesses durability capable of withstanding external impacts, making it suitable for long-term operation. When constructed with these materials, the device and all components for mounting can be configured with a weight of 80 kg to 200 kg, depending on the size of the aircraft engine. The auxiliary frame (4), located in the middle of the device, increases the bonding strength of each frame and also has an airflow that pushes outward, allowing it to protect the engine from external impacts on its own. • Air intake volume: The air intake volume is corrected through the rim-frame (Fig. 3). When viewed from the front (Fig. 4), if the combined area ratio of the cone and the frame is configured to be 18% of the area of ​​the engine intake, it affects the air intake volume; however, this can be corrected by widening the diameter of the engine body. Although the structure of the device can affect the air intake into the engine, the intake volume is optimized by mounting a rim-frame on the engine body to correct this. This additional device facilitates airflow and has the characteristic of minimizing the impact on engine performance.
