CIVIL AIRCRAFT PROTECTION SYSTEM Russian patent published in 2008 - IPC F41H11/02 

FIELD: civil aircraft flight safety support systems.

SUBSTANCE: the aircraft system for protection from missiles with infra-red homing heads uses the fact and missile launch co-ordinates sensors located on the flight vehicle, transceiver with the turn indicator and the optical channel, whose output is connected to the sensor of the missile co-ordinates in the trajectory of its flight and the receiver of the reflected radar radiation, on-board computer, and the generator of laser radiation with its starter. A fluoro-hydrogen-deutoreum generator of laser radiation is used. The on-board computer is made for computation of the co-ordinates of the missile launching point, tracking of its flight in the space, transmission of information of the ground flight safety support system and to the unbiased monitoring system, production of the control signal to the turn drive of the transceiver for orientation of the optical system input to the launched missile and of the control signal to the starter of the HF-DF generator. The novelty of the system is in fact that the sensor of the missile co-ordinates in the trajectory and the receiver of the reflected radiation are provided with devices for protection against HF-DF generator radiation, the computer is made with an additional opportunity to produce a start signal to the starter of the HF-DF generator, transmission of information to the flight vehicle, control system on the fact of the missile drift/non-drift from the trajectory in its flight.

EFFECT: enhanced reliability.
