DYNAMIC AIRCRAFT SIMULATOR BENCH Russian patent published in 2013 - IPC G09B9/12 

FIELD: aircraft engineering.

SUBSTANCE: proposed bench comprises moving platform to support payload, fluid feed source and hydraulic drives. Said drives serve to vary platform position in space. Every said drive has electric control input and consists of interconnected position transducer, adder, power amplifier, hydraulic booster and three-chamber actuator cylinder articulated with platform and foundation via rod and body, respectively. Electric control input is connected to adder second input Hydraulic booster fluid input is communicated via delivery and drain lines with fluid feed source while position transducer is coupled with hydraulic cylinder rod. Dynamic bench comprises also working fluid pressure stabilisation system common for all compensation chambers of hydraulic cylinders. Said system consists of interconnected pressure transducer, adder, power amplifier, hydraulic booster with its input connected with inputs of pressure transducer, hydro accumulator, safety valve and all compensation chambers. Booster fluid inlet is connected via drain and delivery lines to fluid feed source while adder second input is connected to reference voltage source.

EFFECT: higher accuracy of simulation, simplified design, power savings.
