INSTALLATION OF DEMONSTRATION OF SURGE OF INPUT DEVICE Russian patent published in 2024 - IPC G09B25/02 

FIELD: training means.

SUBSTANCE: plant comprises axial fan 1, driven by electric motor of variable power 2 with nozzle 3 and straightening grid 4, which enables to simulate an incident flow, air intake 5, which moves in axial direction by mechanism 6 and allows to change volume in cavity of air intake channel A to receiver 7, device for controlling air flow rate through air intake made in form of movable panel 8, device for controlling air flow rate through receiver made in form of movable panel 9, movement of panels 8 and 9 makes it possible to change area of inlet into air intake due to movement of rod of mechanism 10, device for controlling the air flow rate into the receiver, made in the form of rotary flap bypass 11, located on the surface of the air intake and controlled by mechanism 12, through which part of the air is bypassed, regulator of local angle of incident flow 13, located in front part of air intake and controlled by mechanism 14, device for extraction part of air from the boundary layer on front panel 8, made in the form of fan 15 and adjustable throttle device 18, which provide rarefaction in cavity B and extraction of part of air volume from air intake 5, device for extraction a part of air from the boundary layer of rear panel 9, made in the form of fan 16 and adjustable throttle device 19, which provide a rarefaction in cavity C and extraction a part of the air volume from receiver 7, elastic membrane 17 separating cavities B and C, receiver 7 located behind the air intake, made in the form of a thin-walled stretchable impermeable shell 20, longitudinal elastic elements 21 located outside the shell, connected to fixed ring 22 on one side and movable ring 23 on the other, movable ring turning mechanism 24, movable outlet pipe 25, which moves in axial direction by mechanism 26 and allows to change volume of cavity D after receiver 7, throttle device 27 with movable control element 28, which moves in axial direction by means of mechanism 29, front housing of receiver 30, rear housing of receiver 31, input device rotation mechanism 32, input device rotation axis 33, frame 34 accommodates movable rod 35 displaced vertically by mechanism 32. Movable part of receiver 7 is made in the form of thin-walled elastic shell 20, one edge of which is attached by a cylindrical clamp to the front housing of receiver 30, and the other edge is attached to the rear housing of receiver 31.

EFFECT: described is installation for demonstration of surge of input device.
