The invention discloses a horizontal ejection-impact type blade bird cutting test device. The device comprises an air cannon, projectiles launched by the air cannon, a slideway, an impulse conversiondevice, a test blade and a test bird body, wherein the impulse conversion device serves as an impulse conversion medium, the impulse of the shots launched by the air cannon is transferred into the test blade, and the process that the test blade impacts the test bird body is used for simulating blade bird cutting. As the projectile does not directly impact the test blade and does not need to directly hit the test blade from a gun barrel, different types of bird impact blades are simulated by impacting the test bird body with the test blade, and convenience and accuracy of the bird impact resistance blade test method are improved. The invention further provides a test method using the test device.
本发明公开一种水平弹射‑撞击式叶片切鸟试验装置,包括空气炮、空气炮发射的弹丸、滑道、冲量转换装置、试验叶片、试验鸟体,以冲量转换装置作为冲量转换的中介,将空气炮发射弹丸的冲量转移到试验叶片中,试验叶片撞击试验鸟体的过程作为叶片切鸟的模拟。由于弹丸不直接冲击试验叶片,同时也不需要直接从炮管中打出试验叶片,通过试验叶片撞击试验鸟体模拟不同种类的鸟撞击叶片,提高了抗鸟撞叶片试验方法的便捷性和准确性。本发明还提供了使用该试验装置的试验方法。
