REMOTE REDUNDANT SYSTEM OF AUTOMATED MODAL CONTROL IN LONGITUDINAL CHANNEL OF MANEUVERED MANNED AND UNMANNED AIRCRAFTS Russian patent published in 2018 - IPC B64C15/00 B64C13/16 G05D1/00 

FIELD: aviation.

SUBSTANCE: remote redundant system of automated modal control in the longitudinal channel of maneuvered manned and unmanned aircrafts contains a pilot handle/pitch setting device, a pitch angle autopilot calculator, a servo drive, a pitch angle sensor, a limit regimes restrictor, a pitch angular velocity sensor, a balancing unit, a modal control algorithm calculator (MCAC), an air data system, a linear acceleration sensor, an attack angle identifier, connected in a certain way. The servo drive contains a hydraulic drive and a minimum signal selector. The marginal condition limiter contains a maximum attack angle selector and an angle-of-attack restriction machine computer. MCAC contains a signal conditioner of averaged reduced lift force coefficient, a program unit of system transfer function by pitch angular velocity signal, a discrepancy unit of pitching angular velocity, a control signal conditioner.

EFFECT: improved flight safety due to improved control characteristics.
