Multi-channel onboard microsecond pulse plasma flowing control power supply

Abstract

The invention discloses a multi-channel onboard microsecond pulse plasma flowing control power supply. The multi-channel onboard microsecond pulse plasma flowing control power supply comprises a high-voltage module and a control module, wherein the high-voltage module comprises a first onboard battery DC inversion module, a voltage multiplication charging module, a channel selection module and a pulse formation module, and the control module comprises a remote controller, a receiving antenna, a receiver, a first fiber isolation plate until an N(th) fiber isolation plate, a first signal outputend until an N(th) signal output end and a second onboard battery. The power supply is provided with a plurality of output channels and can independently work, the various functions such as unmanned aerial vehicle plasma flowing control suppression separation, delayed speed reduction and rolling moment control can be achieved by combined application of multiple channels. The power supply also hasthe characteristics of small size and light weight, and remote control can be performed by the remote controller.

Description

technical field [0001] The invention relates to plasma flow control technology, in particular to a multi-channel airborne microsecond pulse plasma flow control power supply. Background technique [0002] Plasma flow control technology is a new type of active flow control technology, which has become an important research hotspot in the field of aerodynamics and aerothermodynamics in the world in recent years. A high-voltage pulse is applied between the two electrodes of the plasma actuator to ionize the air to form plasma. Plasma flow control can significantly suppress boundary layer separation and increase wing lift. Simultaneously applying plasma excitation on both sides of the aircraft wing can maximize the lift of the aircraft and delay the stall, while applying excitation to one side of the wing alone can increase the lift on one side of the wing while keeping the lift on the other side unchanged, thus Generate a large rolling moment to control the attitude of the air...

AI Technical Summary

Problems solved by technology

However, the traditional high-voltage pulse power supply is bulky and heavy, and cannot be controlled remotely, and most of them use 220V mains power supply, which is only suitable for laboratory operation and difficult for airborne use.

In addition, a single high-voltage pulse power supply often only has one output, and two power supplies need to be installed in the roll control to drive the exciters on both sides of the wing to work independently, occupying a larger cabin volume and load capacity
