The invention belongs to the avionics system design technology, and relates to an aircraft icing stall warning system and method. The aircraft icing stall warning system comprises a conversion relay,an icing stall warning indicator lamp, an icing stall alarm, a non-icing stall alarm, a heating mounting plate and a heating switch. When the aircraft is frozen, the ice shape extends forwards, the airflow standing point is changed, a tongue piece of the freezing stall alarm is triggered, a microswitch in the freezing stall alarm is triggered, and a stall alarm signal is given; and in a non-icingstate, under the condition of no ice shape influence, the non-icing stall alarm is triggered by stall, and a stall alarm signal is generated. The system is simple in structure, not complex in controllogic, easy to implement, low in cost, capable of sending an accurate stall warning signal to the aircraft when the aircraft is frozen, capable of improving the safety of the aircraft, and suitable for being applied to general aircrafts.
本发明属于航电系统设计技术,涉及一种飞机结冰失速警告系统及方法。本发明飞机结冰失速警告系统包括转换继电器、结冰失速警告指示灯、结冰失速告警器、非结冰失速告警器、加热安装板、加热开关。飞机结冰时,冰形向前伸长,改变气流驻点,并触发结冰失速告警器舌片,并触发结冰失速告警器内部微动开关,给出失速告警信号;非结冰时,在无冰形影响下,失速触发非结冰失速告警器,产生失速告警信号。本发明系统结构简单,控制逻辑不复杂,实现容易,成本较低,能够在飞机结冰下,给飞机发出准确的失速警高信号,提高飞机安全性,适用于在通用飞机上应用。
