Yaroslav I. Perfecting of Eddy Control Devices Hydraulic Performances of Jet Final Control Sets

With the purpose of increasing of throughput capacity, decreasing of current cutting parameters and improving of dynamic patterns studies of vortex valves - boosters with diffuser on exit are fulfilled. Three types exit diffusers are reviewed: axial, axial-radial and slotted type. With help of designed adequate mathematical models the pattern of cur-rent in vortex chamber are obtained, the field of merging streams of power sup-ply and control, zone of forming of current before diffuser both "throat" section and field of a diffuser of a vortex valve - booster with a slotted type diffuser on an exit and dynamic of a jet pneumoactuator of system exact sow sabadilla are obtained also. An orifice coefficient depending on experimentally of geometri-cal arguments of a slotted type diffuser and its optimum sizes are defined. Comparative analysis of capacity of a vortex valve - booster with axial, axial-radial and slotted type diffuser on an exit are fulfilled operating characteristics of a vortex valve - booster with diffusers of different types are obtained. The method of engineering account of a vortex valve - booster is supplemented by the account of features diffuser of an exit, and it allows to receive a vortex valve - booster with higher dynamic properties. Key words: rotational flap - booster, diffuser, mathematical model, static and dynamic response, transmission function.
