DEVICE FOR LIMITATION OF AIRCRAFT ANGLE OF ATTACK Russian patent published in 2006 - IPC B64C13/00 

FIELD: aircraft control systems; construction of systems for limitation of aircraft pilotage parameters at attaining permissible limiting magnitudes.

SUBSTANCE: proposed device includes true angle-of-attack forming unit and permissible limiting angle-of-attack forming unit whose inputs are connected to output of sensors showing present position of flaps, M number, wing high-lift devices, wing sweep angle, versions of weight load, versions of external store and low-pass filter to whose input signals from angle-of-attack sensor, M number sensor and static pressure sensor are supplied. Output of true angle-if-attack shaping unit is connected to inputs of differentiating unit and adder. Supplied to second input of adder is signal from multiplying unit whose inputs are connected to outputs of differentiating unit and lead coefficient setter. Magnitude of this coefficient is formed depending on signals from M number sensor and static pressure sensor.

EFFECT: enhanced safety of pilotage due to enhanced accuracy of aircraft angle-of-attack control.
