考虑到舰载飞机的非对称着舰和非对称拦阻,建立了六自由度的着舰拦阻动力学模型,对拦阻过程中的飞机动态响应进行了分析,讨论了航母运动对拦阻性能的影响。结果表明:航母纵摇和垂荡、横摇和艏摇分别是造成纵向、横向着舰偏差的主要原因;各运动对拦停距离和机体航向加速度影响程度不同,从大到小依次为:纵摇、横摇、垂荡、艏摇;在非对称拦阻力的作用下,机体的横向偏差可得到修正。
A six-degree-of-freedom dynamics model of landing and arresting of a carrier-based aircraft is established taking asymmetric situation into consideration.The aircraft dynamic response during arresting is calculated.The effect of carrier movement on the arresting performance is analyzed,and the kinetic cause of this phenomenon is also discussed in detail.From the landing and arresting calculation,three important conclusion are obtained:the pitch and heave,the roll and yaw movement of carrier are the primary source of the longitudinal and lateral landing error respectively;The effects of carrier movements on arrest-stop distance and acceleration in the heading direction differ in the degree,while they are pitch,roll,heave and yaw movement in descending order;Under the asymmetric arresting force,the lateral error is corrected.
