DEVICE FOR DETERMINATION OF ANGLE OF ATTACK (SLIP ANGLE) OF FLYING VEHICLE Russian patent published in 1995 - IPC

FIELD: aeronautical engineering. SUBSTANCE: device is provided with Mach transducer, barometric altimeter and unit for determination of correction of coefficients and time constant of low-frequency filter; low-frequency filter is made as low-frequency filter of 1 st order; unit for determination of correction of coefficients and time constant of low-frequency filter has six setters of permanent parameters, air density signal shaper, air velocity signal shaper, shaper of decrement of damping of signal of aerodynamic angle sensor at zero altitude, shaper of signal of natural frequency of sensitive element oscillation of aerodynamic angle sensor at zero altitude, three division units, three multiplier units, adder, subtraction unit, two square-rooting units, two squarers, cubing unit and two amplifiers. EFFECT: enhanced accuracy of determination of angle of attack (slip angle). 2 dwg
