METHOD FOR AUTOMATIC CONTROL OF HIGHLY-MANEUVERABLE AIRCRAFT FLIGHT Russian patent published in 2008 - IPC B64C13/18 

FIELD: transportation, aviation.

SUBSTANCE: upon information system failure there is switchover from primary control loop to backup control loop. Backup control loop saves current values of flight altitude-speed parameters. According to signals from integrated transducers unit ratios are set equal in primary and backup control loops and corresponding to signals from information system about current altitude-speed parameters. This allows performing "bumpless" switchover from primary control loop to backup control loop when information system fails. When information system fails backup loop control signal is generated. At that ratios are changed in time in response to signals from integrated transducers unit depending on saved values of altitude-speed parameters at the moment of information system failure in such a way that required characteristics of stability and controllability during airplane flight along its trajectory of return to airdrome could be provided.

EFFECT: improving safety of highly-maneuverable aircraft flight when information system has failed.
