The invention discloses a helicopter rotor anti-icing and deicing blade fault automatic detection circuit. A heating signal of the partition 1 is connected with a contact 4 of a power supply control relay 2-P1, and is connected with a control input end of the power supply control relay 2-P1 at the same time; a contact 6 of the power supply control relay 2-P1 is suspended, a contact 5 is connected with a control input end of the odd-number blade connection contactor P4 through a channel 6 of the collector ring channel, a control output end of the power supply control relay 2-P1 is respectively connected with contacts 2 of the fault control relays P2 and P3 through collector ring channels 5 and 8, and contacts 1 of the fault control relays P2 and P3 are grounded; a power supply is connected with a contact 1 of the power supply control relay 2-P1, a contact 2 is suspended, and a contact 3 is connected with an alarm lamp N3. According to the invention, the problem that the system cannot position the faulted blade when the heating element of the anti-icing and deicing blade of the helicopter rotor has a short circuit or open circuit fault is solved.
本发明公开了一种直升机旋翼防除冰桨叶故障自动检测电路。分区1加热信号连接电源控制继电器2‑P1触点4,同时连接电源控制继电器2‑P1控制输入端;电源控制继电器2‑P1触点6悬空,触点5通过集流环通道的通道6连接奇数桨叶接通接触器P4控制输入端,电源控制继电器2‑P1控制输出端通过集流环通道5、8分别连接故障控制继电器P2、P3的触点2,故障控制继电器P2、P3的触点1接地;电源连接电源控制继电器2‑P1触点1,触点2悬空,触点3连接告警灯N3。本发明解决了直升机旋翼防除冰桨叶加热元件出现短路或断路故障时,系统无法定位出故障桨叶的问题。
