The article discusses the results of investigations of simulations aimed at determination of characteristic of throttle in the flow synchronization valve (synchronizer). The hitherto existing linear characteristic was able to assure the correct work of the arrangement at a definite point of work only. To improve the work of the arrangement, it was attempted to get the non-linear characteristics of the nozzle. Two methods were applied: the polynomial approximation of working points of the synchronizer for the bundle of linear characteristics, and optimisation at the modified criterion.
