METHOD FOR OPERATING AN AIRCRAFT, FLIGHT CONTROL SYSTEM FOR AN AIRCRAFT AND AIRCRAFT WITH SUCH A FLIGHT CONTROL SYSTEM

摘要

A method for operating an aircraft with N>4 drive units, preferably in the form of electrically driven rotors, where a flight control system generates control commands μCOM, μCOM∈U⊂RN, for the drive units, via a first channel and transmits them to the drive units, where U represents limitations of the drive units; the flight control system also generates pseudo-control commands γCOM, γCOM∈R4, in the first channel, which specify torques about corresponding axes of rotation of the aircraft and a thrust, a control matrix M∈R4×N according to γ=M μ establishing a relationship with the control commands μ; in the first channel, admissible control commands μCOM∈U are calculated from the pseudo-control commands γCOM by an allocation algorithm; and the first channel is monitored by an independent second channel and, based on a monitoring result, is passivated. Monitoring of the first channel takes place in the second channel, in that pseudo-control commands γMON, γMON⊂R4, are likewise generated in the second channel and the control commands μCOM of the first channel are evaluated in the second channel by the relationship γ*=M μCOM, for which γ* and γMON are compared with one another. A flight control system for carrying out the method and an aircraft equipped with such a flight control system are also provided.
