Description
technical field:
the utility model relates to a kind of Plasma Actuator device using pottery as dielectric.
background technology:
the object that aircraft flowing controls is the lift, the minimizing resistance that increase aircraft, improves and rises/resistance ratio, thus improve the aeroperformance of aircraft.In flowing controls, plasma controls a kind of method controlled as flowing, owing to there is no moving component, there is the advantages such as structure is simple, size is little, lightweight, the air-operated drive effect bandwidth of applying, excitation parameters are convenient to real-time control, respond rapidly soon, energy consumption is lower, reliability is strong, becoming the flowing of a kind of new concept aircraft and control thinking, is that the important breakthrough technology that the emerging important research field in international aerodynamics and plasma physics field becomes active Flow Control field most probably makes aircraft and power set performance be greatly improved.
the method producing plasma is a lot, in flowing controls, the most practical method is atmospheric pressure glow discharge plasma (OAUGDP at present, OneAtmosphereUniformGlowDischargePlasma), also known as dielectric barrier discharge, its typical effect mode is the air-spray based on the induction of plasma electrically fluid power.Air in flow field near plasma generator is ionized formation plasma under the effect of highfield, plasma is under the effect of space non-uniform electric field, to the directed movement of electric-force gradient direction, by with surrounding air generation momentum-transport and blending, realize flowing control.
what dielectric barrier discharge plasma exciter medium material was appeared in the newspapers mostly is the stronger material of the insulation property such as epoxy resin fiber plate, polytetrafluoroethylene, the Plasma Actuator of these media can be applicable to the Control experiment that flows, in flowing Control experiment, some plasma dielectric pole plate existing is slightly large at discharge power, time slightly long pole plate temperature raises very fast, be subject to thermal change soft, airfoil shape is finally caused to change, very large on the accuracy impact of data.In addition some dielectrics contain more impurity, add that quality is uneven, and discharge voltage is slightly high just easily breakdown.Use the Plasma Actuator using pottery as dielectric of the present invention can overcome existing unfavorable factor.
summary of the invention:
the purpose of this utility model is to provide a kind of Plasma Actuator device using pottery as dielectric.
above-mentioned object is realized by following technical scheme:
a kind of Plasma Actuator device using pottery as dielectric, its composition comprises: ceramic wafer, nanosecond pulse power supply, top electrode bar, electrode strip connecting line, lower electrode strip, plasma, described ceramic wafer is dielectric plate, top electrode bar is pasted with above described dielectric plate, lower electrode strip is pasted with below described dielectric plate, described top electrode bar is connected with nanosecond pulse power supply by electrode strip connecting line with lower electrode strip, described top electrode bar and lower electrode strip are staggeredly arranged up and down at dielectric plate, between described top electrode bar and dielectric plate, there is plasma.
the beneficial effects of the utility model:
1. the utility model is according to the principle of dielectric barrier discharge, and medium has enough insulating capacities, and can induce enough large electromotive force generation plasma in the power supply rear surface that adds high pressure, and plasma will move along the gradient direction of electromotive force.And in conjunction with the inconvenient factor of current conventional Plasma Actuator, we adopt using pottery as dielectric, and this pole plate has the advantages such as high temperature resistant, dielectric constant is high, stable chemical performance, compares the dielectric being suitable as Plasma Actuator.
the utility model it be made up of ceramic wafer and metal tape (as copper foil tape, aluminum foil and adhesive tape etc.).Pottery have high temperature resistant, not easily puncture, the advantage such as surface smoothness is good, dielectric constant is optional, stable chemical performance, compare the dielectric being suitable as Plasma Actuator.In addition, be pasted onto aircraft surfaces using pottery as the Plasma Actuator of dielectric, do not destroy the geometric parameter of aircraft surfaces, be particularly suitable for being used in aircraft surfaces and carry out plasma flow control.This Plasma Actuator energy ezpenditure using pottery as dielectric is low, and flowing control effects is good, and processing cost, installation difficulty, maintenance cost are all very low, and can reuse.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
