DYNAMIC STAND Russian patent published in 2006 - IPC G09B9/08 

FIELD: automatic adjustment technologies, namely, a dynamic stand - aviation training machine, working as part of complex for semi-natural modeling of flight conditions during training of airplane crews.

SUBSTANCE: dynamic stand contains a platform, carrying useful load, hydraulic power source and hydraulic drives, each one of which has electric control input and consists of serially connected sensitive element, adder, power amplifier, hydraulic amplifier and force hydraulic cylinder. Electric control input is connected to second input of adder, output of hydraulic power source is connected to second input of hydraulic amplifier, while input of sensitive element is connected to platform. Additionally provided are computing device, commutation device, emergency electric power source and, connected serially, device for controlling position of hydraulic cylinders and device for locking the platform. In each hydraulic drive between adder and power amplifier a controllable key is mounted, controlling input of which is connected to electric drive of emergency control, while second input is connected to output of commutation device, matching the hydraulic drive. Controlling input of commutation device is connected to output of device for controlling position of hydraulic cylinders, inputs, in accordance to number of hydraulic cylinders - to outputs of computing device and additionally one input - to output of device for platform locking. Controlling input of platform locking device is connected to electric emergency control input. Output of sensitive element of each hydraulic drive is connected to appropriate inputs of device for controlling position of hydraulic cylinders and computing device, while one additional input of computing device is connected to output of emergency electric power source.

EFFECT: increased safety of crew in training.
