The invention belongs to the field of helicopter design, and particularly relates to a helicopter attitude auxiliary alarm device and method based on a mercury switch. At present, main sources of attitude signal acquisition of helicopters are mechanical gyroscope groups, fiber-optic gyroscope groups, laser gyroscope groups and the like, and no attitude overrun alarm device exists. A horizontal installation plate is arranged on a base, first mercury switches and second mercury switches are installed on the top of the installation plate in a cross-shaped layout mode, the number of the first mercury switches is four, the first mercury switches are distributed on the outer cross-shaped position in an axial symmetry mode, and the outward inclination angle ranges from 20 degrees to 30 degrees; the number of the second mercury switches is four, the second mercury switches are distributed on the inner cross position in an axial symmetry mode, and the outward inclination angle is 40-50 degrees; the longitudinal first mercury switch and the longitudinal second mercury switch are consistent with the course; the first mercury switch and the second mercury switch are connected with the signal lamp and the buzzer through wires. The device is small in size, low in cost and convenient to install, and the influence on the aircraft structure and the electrical performance can be ignored.
本发明属于直升机设计领域,特别是涉及一种基于水银开关的直升机姿态辅助告警设备及方法。目前的直升机上,姿态信号获取的主要来源是机械陀螺组,光纤陀螺组和激光陀螺组等,没有姿态超限的告警装置。本发明在基座上具有水平的安装板,在安装板顶部以十字形布局安装第一水银开关和第二水银开关,其中第一水银开关的数量为四个,轴对称分布在外十字位置上,向外倾角为20‑30°;第二水银开关的数量为四个,轴对称分布在内十字位置上,向外倾角为40‑50°;纵向的第一水银开关和第二水银开关与航向一致;第一水银开关和第二水银开关通过导线与信号灯与蜂鸣器连接。体积小,成本低,便于安装,对飞机结构和电气性能影响可以忽略不计。
