FIELD: aviation.
SUBSTANCE: device for indicating a stall in the helicopter rotor blades contains fiber-optical sensors with optical input/output, fixed on the surfaces of non-rotating parts of the helicopter's swashplate, a panel stall indicating light, an electric data transfer bus bar, fiber-optical cable, fiber-optical connector, recorder unit. The recorder unit contains a spectral analysis unit, a digital-to-analog converter, a fiber-optical switching unit, a light source unit, a data storage unit, a data analysis unit, a power supply unit, an agile bandpass filter, two threshold devices, an AND circuit, a low-pass filter connected in a certain way.
EFFECT: flight safety by increasing the probability of detecting a flow stall.
