摘要:

为完成某舰载飞机飞行试验任务,采用应变法实测了其拦阻着舰时的拦阻钩载荷。在分析着舰拦阻过程中拦阻钩受载状态的基础上,建立了拦阻钩纵向、侧向和垂向这3个方向上的载荷模型;对拦阻钩钩臂进行内力分析,设计了载荷测量应变电桥,并进行了载荷校准,建立了载荷方程。给出并详细分析了典型拦阻过程中的拦阻钩载荷,计算了拦阻功量及拦阻系统的效率。最后,通过与常规单向载荷模型的对比,探讨了采用三向载荷模型的意义。分析表明,建立的模型和采用的方法正确,结果合理可信,可供相关工程参考。

Abstract:

For the purpose of complete flight test mission of a carrier-based aircraft, its arresting hook loads are measured using strain gage. A three-direction (longitudinal, lateral and vertical directions) load model of arresting hook is built through analyzing the loads in the arrest deck-landing process. Strain gages are designed and installed on the arresting hook. Ground calibration tests are implemented and load equations are constructed. Some typical loads of arresting hook in the process of carrier-based aircraft arrest deck-landing are also presented in detail, and the arresting energy and efficiency of arresting gear equipment are studied. Moreover, compared with the loads obtained by an ordinary single-direction load model, the three-direction load model is discussed. The results show that the load model and measurement methods are correct and credible, which can provide some references for the engineering practice.

Key words: flight test, flight measurement of load, carrier-based aircraft, arresting hook, arrest deck-landing, strain-gage bridge
