DEVICE FOR VISUAL CHECK OF SPATIAL ATTITUDE AND SPEED OF RECEIVER AEROPLANE DURING IN-FLIGHT REFUELLING Russian patent published in 1997 - IPC

FIELD: in-flight refuelling. SUBSTANCE: device includes light source and its control unit mounted on receiver aeroplane. Light source is made in form of one central and two lateral laser optical modules mounted for angular displacement relative to central module. Laser beams are adjusted with axis of fuel receiving device. Light source control unit includes brightness modulators of central laser beam and one lateral laser beam, monitoring unit, control unit, device for programmed separation of lateral laser optical modules and power supply unit. Outputs of modules are connected to monitoring unit and inputs of central and one lateral modules are connected to respective modulator; each of them is connected to monitoring unit and power supply unit connected with monitoring unit which is connected in its turn with control unit and lateral module programmed separation device whose actuator is kinematically linked with housings of lateral modules. EFFECT: enhanced efficiency. 5 cl, 11 dwg
