The invention particularly relates to an indicator drive circuit structure for realizing five attack angle states of an airplane. The structure comprises an indicating lamp L1 (identification symbol:'V'), an indicating lamp L2 (identification symbol: '('), an indicating lamp L3 (identification symbol: ')') and an indicating lamp L4 (identification symbol: 'inverted V'). The brightness of the indicating lamp L1, the indicating lamp L2, the indicating lamp L3 and the indicating lamp L4 is logically controlled respectively by using different combination modes of the attack angle large signal A,the attack angle normal signal B and the attack angle small signal C, so that five states of large attack angle, relatively large attack angle, normal attack angle, relatively small attack angle and small attack angle are realized. The beneficial effects of the invention are that the whole circuit achieves five indication states, provides more accurate attack angle information for a pilot, adjuststhe attack angle in time in the take-off and landing and flight processes, guarantees the normal operation of take-off and landing, avoids the stall risk of a critical attack angle, and guarantees the stable flight.

    本发明具体涉及实现飞机五种迎角状态的指示器驱动电路结构,包含有,指示灯L1(标识符号:“∨”)、指示灯L2(标识符号:“(”)、指示灯L3(标识符号:“)”)及指示灯L4(标识符号:“∧”),利用迎角大信号A、迎角正常信号B及迎角小信号C三者的不同组合方式分别逻辑控制所述指示灯L1、指示灯L2、指示灯L3及指示灯L4的亮暗,以实现迎角大、迎角较大、迎角正常、迎角较小及迎角小的五种状态。本发明的有益效果在于:整个电路实现的五种指示状态,为飞行员提供更准确的迎角角度信息,在起降和飞行过程中及时调整迎角,保证起降的正常进行,避免临界迎角的失速危险,保证平稳飞行。
