Description
Technical Field
The utility model relates to an aircraft intake duct field, concretely relates to load S type intake duct of dielectric barrier discharge plasma exciter.
Background
Modern aircraft are increasingly demanding on speed and maneuverability, and increasingly stringent engine performance requirements. Optimizing the air intake is one of the important measures to improve the performance of the propulsion system. The inlet duct needs to provide sufficient mass flow to the engine while ensuring flow uniformity, and in addition, for the complete machine, its length, mass, etc. are related to the inlet duct. The S-shaped air inlet channel can effectively reduce the size of the air inlet channel due to the fact that the axial distance of the S-shaped air inlet channel is short, radar waves are subjected to a series of reflections between the walls with large curvature after entering the air inlet channel, the energy of the radar waves is weakened to different degrees in the reflection process, the scattering area of the radar is reduced, and accordingly stealth is improved. However, the flow of the air in the S-shaped intake duct is more complicated than that in the conventional intake duct. In the large-curvature bending section, the air flow is subjected to flow separation due to a strong adverse pressure gradient, and the total pressure recovery coefficient of the outlet section of the air inlet passage is reduced due to the flow separation, so that the effective thrust is reduced. The twin scroll structure also produces large pressure distortion at the outlet of the air inlet, which deteriorates the performance of the engine and may even cause the compressor of the engine to surge or stall.
The plasma flow control is a novel active flow control, and can realize the purposes of reducing resistance, increasing lift, effectively controlling separation and the like. There are various forms of plasma flow control, one of the most interesting of which is the so-called Dielectric Barrier Discharge (DBD) plasma flow control. The DBD plasma exciter can be widely applied to flow control under various conditions, such as boundary layer control, airfoil lift coefficient lifting, airfoil stall attack angle increasing, high-lift airfoil flow separation control and the like.
The invention patent application with publication number CN107701314A discloses a flow control method for improving starting performance of an air inlet by utilizing a flexible wall surface, and relates to an air inlet of a ramjet engine. Determining the type selection of the flexible material according to the flow field pressure oscillation frequency and the amplitude when the air inlet channel is not started; determining the size of the flexible wall surface according to the size of an airflow separation area at an inlet of a compression section when the air inlet channel is not started; and determining the initial installation position of the flexible wall surface according to the initial position of the airflow separation area. When the air inlet channel is not started, the pressure of the flow field periodically oscillates to drive the flexible wall surface to generate tiny oscillation, so that the energy of the oscillating flow field is transferred and dissipated to the flexible wall surface, the oscillation of the flow field is restrained, and the purpose of improving the starting characteristic of the hypersonic air inlet channel is achieved. The air inlet duct has the disadvantages that the wall surface of the air inlet duct needs to be modified, and the engineering quantity is large.
The invention patent application with the publication number of CN108104950A discloses that a partition board for isolating a shock wave incident into a lip and an upper wall surface boundary layer of an air inlet is additionally arranged on an incident shock wave path at the lip of the air inlet, so that the shock wave incident into the lip of the air inlet can act on the partition board to isolate the shock wave incident into the lip from the upper wall surface boundary layer of the air inlet, and the incident shock wave can not interact with the boundary layer, thereby reducing or even eliminating the separation of the upper wall surface boundary layer of the air inlet.

The first excitation power supply adopts an alternating current power supply. The first controller is electrically connected with the first excitation power supply and is used for controlling and changing the voltage amplitude and the frequency of the first excitation power supply. When air is introduced, the first controller controls the first excitation power supply to provide a high-voltage alternating current to the DBD plasma exciter 20, so that an induced air flow is formed in both the front area and the rear area of the first electrode 3 of the DBD plasma exciter 20, thereby suppressing the separation of the air flow at the position of the air inlet AA'.

The extending direction of the first flexible insulating medium layer 1 of the three DBD plasma exciters 20 is also the same as the width direction of the air inlet channel, and the three DBD plasma exciters 20 are arranged at intervals along the air inlet direction and have the same interval. Each DBD plasma exciter 20 has only one strip-shaped first electrode 3 and one strip-shaped second electrode 4, and the spread direction of the first electrode 3 and the second electrode 4 is also the width direction of the gas inlet passage. The first electrodes 3 of the three DBD plasma exciters 20 are connected with each other and connected to one pole of a third excitation power supply; the second electrodes 4 of the three DBD plasma actuators 20 are connected to each other and connected to the other pole of the third driving power source. The third excitation power supply also adopts a pulse power supply.

And the DBD plasma exciter 20 is flexibly attached to the inner wall of the channel of the air inlet channel, has no moving part, and has the advantages of simple structure, small volume, convenient manufacture, response speed block and low input power.
