DEVICE FOR ENGAGEMENT OF GYRO HORIZON IN PILOTAGE COMPLEX Russian patent published in 2003 - IPC

FIELD: aviation material. SUBSTANCE: the device has sine-cosine rotary transformers with output bank and pitch windings, storage battery feeding the voltage converter, as well as a unit for determining the bank and pitch angle limits, emergency warning and cautionary enunciator. The converter output bus-bars with 36-V 400-Hz three- phase voltage and +5-V and +27-V DC voltages are connected to the supply inputs of the gyro horizon, and bus-bars with +-15-V and +5-V DC voltages - to the supply inputs of the units for determining the bank and pitch angle limits. The "bank high left", "bank high right", "pitch high, diving" and "pitch high, pitch-up" outputs of the above units are connected to the enunciator. The output bank and pitch windings of the sine-cosine rotary transformers of the gyro horizon are connected to the inputs of the units for determining the bank and pitch limits. Realization of the supply circuits and the circuit of engagement of the gyro horizon provides for equipment of general aviation aeroplanes with minimum dimensional and mass characteristics with gyro horizons. EFFECT: enhanced safety of flights. 3 cl, 3 dwg
