舰船机库大门对直升机起降特性影响研究

根据舰艉起降甲板的空气流场,结合直升机飞行动力学模型,计算了舰船机库门开启和关闭时的直升机舰面起降特性,并分析了舰船机库门开启和关闭对直升机起降特性的影响。计算结果表明,机库门开关状态仅对直升机总距操纵有一定的影响,而对其他操纵量和机身姿态影响甚小。提供的研究方法和所得结论为舰载直升机舰面起降提供了理论依据,有重要的实际意义。

Study of influence of warship hangar door on helicopter's take-off and landing characteristics

To analyze the influence on helicopters' take-off and landing behavior while hangar door is opened and closed, we computed the helicopter's take-off and landing characteristic in the two states, using the airflow field over warship deck and, in combination with the helicopter flight dynamics model.The result indicates that there are only some differences on helicopter's collective control between the above states, rather than anything else.The method and conclusions provided in this paper can be used as a theoretical basis for helicopter take-off and landing on warship, which is meaningful in practical work.
